Basic Checks: Dell™ OptiPlex™ GX110 System User's Guide
Overview

Checking Connections and Switches

Backing Up Your Files

Look and Listen

Basic Checks

System Setup

Overview
If your Dell computer system is not working as expected, and if you are not sure what to do, start your troubleshooting with the procedures in this
section. This section guides you through basic steps to solve basic computer problems. It also directs you to further detailed troubleshooting
information and procedures to solve more complex problems.

Backing Up Your Files
If your system is behaving erratically, back up your files immediately. If your system has a tape drive installed, see the documentation that came
with the tape backup software for instructions on performing a backup operation. Otherwise, see your operating system documentation for
information on backing up data files.

Basic Checks
See the following sections in the order indicated until the problem is resolved:
l

If your computer is wet or damaged, see "Troubleshooting a Wet Computer" or "Troubleshooting a Damaged Computer."

Perform the steps in "Checking Connections and Switches."

Perform the steps in "Look and Listen."

If your system did not complete the boot (start-up) routine, see "Getting Help."
NOTE: The boot routine is the operating system's attempt to load its files into memory from the boot-up sector on the hard-disk
drive or another bootable device.

If your system displayed a message or emitted a beep code, see "Messages and Codes."

Verify the settings in System Setup.

Run the Dell Diagnostics.

Checking Connections and Switches
Improperly set switches and controls and loose or improperly connected cables are the most likely source of problems for your computer, monitor,
or other peripheral (such as a printer, keyboard, mouse, or other external equipment).
NOTE: See "Controls and Indicators" and "Connecting Peripheral Devices" for the location of your computer's external connections
and switches.
Complete the following steps in the order indicated to check all the connections and switches:
1. Turn off the system, including any attached peripherals (such as the monitor, keyboard, printer, external drives, scanners, or plotters).
Disconnect all the AC power cables from their electrical outlets.
2. If your computer is connected to a power strip, turn the power strip off and then on again. If the problem is not resolved, try another power
strip or connect the system directly to an electrical outlet to see if the original power strip is faulty.
3. Connect the system to a different electrical outlet.
If doing so corrects the problem, the original outlet is faulty.

4. Reconnect the system to an electrical outlet. Make sure that all connections fit tightly together, and turn on the system.
5. If the problem is resolved, you have corrected a faulty connection.
6. If your monitor is not operating properly, see "Troubleshooting the Monitor."
7. If your keyboard is not operating properly, see "Troubleshooting the Keyboard."
8. If your mouse or printer is not operating properly, see "Troubleshooting I/O Ports." Otherwise, see "Look and Listen."

Look and Listen
Looking at and listening to your system is important in determining the source of a problem. Look and listen for the indications described in Table
1.
If after looking and listening to your computer you have not resolved the problem, continue with the recommendations in "System Setup."
Table 1. Boot Routine Indications
Look/Listen for:

Action

An error message

See "Messages and Codes."

The monitor's power indicator Most monitors have a power indicator (usually on the front bezel). If the monitor's power indicator does not light
up, see "Troubleshooting the Monitor."
The power and hard-disk
drive indicators

Use the power and hard-disk drive indicators to help you identify a system problem when you press the power
button to turn on the computer but the system does not boot.

The power indicator

Use the power indicator to help you identify a system problem when you press the power button to turn on the
computer but the system does not boot:
l

A blinking yellow power indicator before power-on self-test (POST) indicates that the power supply may be
faulty. In rare cases, the system board may be faulty. See "Getting Help" for instructions on getting
technical assistance from Dell.
A solid yellow power indicator before POST indicates that a device on the system board may be faulty or
is incorrectly installed. Be sure that the microprocessor is properly seated, remove all expansion cards,
and then reboot. If the system does not boot, see "Getting Help" for instructions on getting technical
assistance from Dell.
A solid green power indicator and a beep code during POST indicate that a dual in-line memory module
(DIMM) may be faulty or is not properly seated. Remove all DIMMs, install only one DIMM, and then reboot.
Repeat this procedure until you identify the faulty or improperly seated DIMM.
A solid green power indicator and no beep code and no video during POST indicate that the monitor or
the integrated video controller may be faulty. See "Troubleshooting the Monitor." If the monitor is operating
properly and is correctly connected, see "Getting Help" for instructions on getting technical assistance
from Dell.
A solid green power indicator and no beep code with video during POST indicate that an integrated
system board device may be faulty. See "Getting Help" for instructions on getting technical assistance
from Dell.

The keyboard indicators

Most keyboards have one or more indicators (usually in the upper-right corner). Press the key, the
key, and the key to toggle the keyboard indicators on and off. If the keyboard
indicators do not light up, see "Troubleshooting the Keyboard."

The diskette-drive access
indicator

The diskette-drive access indicator should quickly flash on and off when you access data on the diskette drive.
On a system running a Microsoft® Windows® operating system, you can test the drive by opening Windows
Explorer and clicking the icon for drive A. If the diskette-drive access indicator does not light up, see
"Troubleshooting Drives."

The hard-disk drive access
indicator

The hard-disk drive access indicator should quickly flash on and off when you access data on the hard-disk
drive. On a system running a Windows operating system, you can test the drive by opening Windows Explorer
and clicking the icon for drive C. If the hard-disk drive access indicator does not light up, see "Troubleshooting
Drives."

A series of beeps

See "Messages and Codes."

An unfamiliar constant
scraping or grinding sound
when you access a drive

Make sure the sound is not caused by the application program you are running. The sound could be caused by a
hardware malfunction. See "Getting Help" for instructions on getting technical assistance from Dell.

The absence of a familiar
sound

When you turn on your system, you can hear the hard-disk drive spin up, and the system tries to access the boot
files from the hard-disk drive or the diskette drive. If your system boots, see "Dell Diagnostics." If your system
does not boot, see "Getting Help."

System Setup
You can easily correct certain system problems by verifying the correct settings in System Setup. When you boot your system, your system checks
the system configuration information and compares it with the current hardware configuration. If your system hardware configuration does not
match the information recorded by System Setup, an error message may appear on your screen.
This problem can happen if you changed your system's hardware configuration and forgot to run System Setup. To correct this problem, enter
System Setup, correct the setting for the corresponding System Setup program option, and reboot your system.
If after checking the settings in System Setup you have not resolved the problem, see "Dell Diagnostics."

Battery: Dell™ OptiPlex™ GX110 System User's Guide
Overview
Replacing the Battery

Overview
A 3.0-volt (V) CR2032 coin-cell battery installed on the system board maintains system configuration, date, and time information in a special
section of memory.
The operating life of the battery can extend up to ten years. The battery may need replacing if an incorrect time or date is displayed during the boot
routine along with a message such as:
Time-of-day not set - please run SETUP program
or
Invalid configuration information please run SETUP program
or
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether you need to replace the battery, reenter the time and date through System Setup and exit the program properly to save the
information. Turn off your system and disconnect it from the electrical outlet for a few hours; then reconnect and turn on your system. Enter System
Setup. If the date and time are not correct in System Setup, replace your battery.
You can operate your system without a battery; however, without a battery, the system configuration information is erased if the system is turned off
or unplugged from the electrical outlet. In this case, you must enter System Setup and reset the configuration options.
CAUTION: There is a danger of the new battery exploding if it is incorrectly installed. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.

Replacing the Battery
To replace the system battery, perform the following steps:
1. If you have not already done so, make a copy of your system configuration information in System Setup.
If the settings are lost while you are replacing the battery, refer to your written or printed copy of the system configuration information to
restore the correct settings.
CAUTION: Before you remove the computer cover, see "Safety First — For You and Your Computer."
2. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."
3. Remove the battery.
See Figure 9 in "Inside Your Computer" for the location of the battery.
NOTICE: If you pry the battery out of its socket with a blunt object, be careful not to touch the system board with the object.
Make certain that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise,
you may damage the system board by prying off the socket or by breaking circuit traces on the system board.
Pry the battery out of its socket with your fingers or with a blunt, nonconductive object, such as a plastic screwdriver.
4. Install the new battery.
Orient the battery with the side labeled "+" facing up (see Figure 1). Then insert the battery into the socket, and snap it into place.
Figure 1. Replacing the System Battery

1 Battery
2 Battery socket

5. Replace the computer cover, reconnect your computer and peripherals to their electrical outlets, and turn them on.
6. Enter System Setup, and confirm that the battery is operating properly.
Enter the correct time and date through System Setup's System Time and System Date options. Also, use the copy you made in step 1 of
the system configuration information to restore the correct settings for other System Setup options. Then exit System Setup.
7. Turn off and unplug your computer. Leave the computer turned off for at least 10 minutes.
8. After 10 minutes, plug in the computer, turn it on, and enter System Setup. If the time and date are still incorrect, see "Getting Help" for
instructions on obtaining technical assistance.

Contacting Dell: Dell™ OptiPlex™ GX110 System User's Guide
Overview

Europe Contact Numbers

International Dialing Codes

Asia and Other Regions Contact Numbers

Americas Contact Numbers

Overview
When you need to contact Dell, use the telephone numbers, codes, and electronic addresses provided in the following sections. "International
Dialing Codes" provides the various codes required to make long-distance and international calls. "Americas Contact Numbers," "Europe Contact
Numbers," and "Asia and Other Regions Contact Numbers" provide local telephone numbers, area codes, toll-free numbers, and e-mail
addresses, if applicable, for each department or service available in various countries around the world.
If you are making a direct-dialed call to a location outside of your local telephone service area, determine which codes to use (if any) in
"International Dialing Codes," in addition to the local numbers provided in the other sections.
For example, to place an international call from Paris, France to Bracknell, England, dial the international access code for France followed by the
country code for the U.K., the city code for Bracknell, and then the local number as shown in the following illustration:

To place a long-distance call within your own country, use area codes instead of international access codes, country codes, and city codes. For
example, to call Paris, France from Montpellier, France, dial the area code plus the local number as shown in the following illustration:

The codes required depend on where you are calling from as well as the destination of your call; in addition, each country has a different dialing
protocol. If you need assistance in determining which codes to use, contact a local or an international operator.
NOTES: Toll-free numbers are for use only within the country for which they are listed. Area codes are most often used to call long
distance within your own country (not internationally)—in other words, when your call originates in the same country you are calling.
Have your Express Service Code ready when you call. The code helps Dell's automated-support telephone system direct your call
more efficiently.

How to Use Dell Diagnostics

Overview
Unlike many diagnostic programs, the Dell Diagnostics helps you check your computer's hardware without any additional equipment and without
destroying any data. By using the diagnostics, you can have confidence in your computer system's operation. If you find a problem you cannot
solve by yourself, the diagnostic tests can provide you with important information you will need when talking to Dell's service and support
personnel.
NOTICE: Use the Dell Diagnostics only to test your Dell computer system. Using this program with other computers may cause
incorrect computer responses or result in error messages.

Features of the Dell Diagnostics
The Dell Diagnostics provides a series of menus and options from which you choose particular test groups or subtests. You control the sequence
in which the tests are run. The diagnostic test groups or subtests have the following helpful features:
l

Options that let you run tests individually or collectively

An option that allows you to choose the number of times a test group or subtest is repeated

The ability to display or print test results or to save them in a file

Options to temporarily suspend testing if an error is detected or to terminate testing when an adjustable error limit is reached

A menu category called Devices that briefly describes each test and its parameters

A menu category called Config that describes the configuration of the devices in the selected device group

Status messages that inform you whether test groups or subtests were completed successfully

Error messages that appear if any problems are detected

When to Use the Dell Diagnostics
Whenever a major component or device in your computer system does not function properly, you may have a component failure. As long as the
microprocessor and the input and output components of your computer system (the monitor, keyboard, and diskette drive) are working, you can
use the Dell Diagnostics. If you are experienced with computers and know what component(s) you need to test, simply select the appropriate
diagnostic test group(s) or subtest(s). If you are unsure about how to begin diagnosing a problem, read the rest of this section.

Before You Start Testing
Turn on your printer if one is attached, and make sure it is online. Enter System Setup, confirm your computer's system configuration information,
and enable all its components and devices, such as ports.
See "Using System Setup" for instructions on entering and using the program.

Starting the Dell Diagnostics
After you complete the preliminary instructions outlined in the previous section, perform the following steps to start the diagnostics:
1. Turn off your system.

2. Insert the Dell Diagnostics media (for example, a diskette or CD) into the appropriate drive.
3. Turn on your system.
When you start the diagnostics, the Dell logo screen appears, followed by a message telling you that the diagnostics is loading.
After the diagnostics loads, the Diagnostics Menu appears (see Figure 1). The menu allows you to run all or specific diagnostic tests or to exit to
the MS-DOS® prompt.
For a quick check of your system, select the Quickly Test All Devices option. This option runs only the subtests that do not require user
interaction and that do not take a long time to run. Dell recommends that you choose this option first to identify the source of the problem quickly.
For a thorough check of your system, select the Fully Test All Devices option. To check a particular area of your system, select the Select
Devices to Test option.
To select an option from this menu, highlight the option and press , or press the key that corresponds to the highlighted letter in the option
you choose.
Figure 1. Diagnostics Menu

Dell Diagnostics Main Screen Overview
When you select Select Devices to Test from the Diagnostics Menu, the main screen of the diagnostics appears (see Figure 2). The main
screen lists the diagnostic test device groups, lists the devices of the selected device group, and allows you to select categories from a menu.
From this screen, you can access the main screens.
Information on the main screen of the diagnostics is presented in the following areas:
l

Two lines at the top of the screen identify the version number of the Dell Diagnostics.
On the left side of the screen, the Device Groups area lists the diagnostic test groups in the order they will run if you select All from the Run
Tests menu category. Press the up- or down-arrow key to highlight a test device group.
On the right side of the screen, the Devices for Highlighted Group area lists the computer's currently detected hardware and some of the
relevant settings.
Two lines at the bottom of the screen make up the menu area. The first line lists the categories you can select; press the left- or right-arrow
key to highlight a menu category. The second line gives information about the category currently highlighted.

Figure 2. Dell Diagnostics Main Screen

Confirming the System Configuration Information
When you boot your system from your diagnostics diskette, the diagnostics checks your system configuration information and displays it in the

Device Groups area on the main screen.
The following sources supply this configuration information for the diagnostics:
l

The system configuration information settings (stored in nonvolatile random-access memory [NVRAM]) that you selected while using System
Setup

Identification tests of the microprocessor, the video controller, the keyboard controller, and other key components

Basic input/output system (BIOS) configuration information temporarily saved in RAM

Do not be concerned if the Device Groups area does not list the names of all the components or devices you know are part of your computer
system. For example, you may not see a printer listed, although you know one is attached to your computer. Instead, the printer is listed as a
parallel port. The computer recognizes the parallel port as LPT1, which is an address that tells the computer where to send outgoing information
and where to look for incoming information. Because your printer is a parallel communications device, the computer recognizes the printer by its
LPT1 address and identifies it as a parallel port. You can test your printer connection in the Parallel Ports tests.

How to Use Dell Diagnostics
Six comprehensive, menu-driven, online help categories provide instructions on how to use the program and explain each menu item, test group,
subtest, and test result. To enter the Help menu, perform the following steps:
1. Highlight Select Devices to Test in the Diagnostics Menu.
2. Press .
3. Press .
The six Help menu categories are Menu, Keys, Device Group, Device, Test, and Versions. The online help also provides detailed
descriptions of the devices that you are testing. The Help menu categories are explained in the following subsections.
Menu Category
The Menu help category describes the main menu screen area, the device groups, and the different diagnostic menus and commands and
instructs you on how to use them.
Keys Category
The Keys help category explains the functions of all keystrokes that you can use in the Dell Diagnostics.
Device Group Category
The Device Group help category describes the test group that is currently highlighted in the Device Groups list on the main menu screen. It also
provides reasoning for using some tests.
Device Category
The Device help category is the educational section of online help. It describes the function and purpose of the highlighted device in the Device
Groups. For example, the following information appears when you select the Device help category for Diskette in the Device Groups list:
Diskette drive A:
The diskette disk drive device reads and writes data to and from diskettes. Diskettes are flexible
recording media, sometimes contained in hard shells. Diskette recording capacities are small and
access times are slow relative to hard disk drives, but they provide a convenient means of storing
and transferring data.
Test Category
The Test help category thoroughly explains the test procedure of each currently highlighted subtest. For example, the subtest Diskette Drive Seek
Test of the Diskette device group lists the following information:
Diskette drive A: - Diskette Drive Seek Test
This test verifies the drive's ability to position its read/write heads. The test operates in two
passes: first, seeking from the beginning to ending cylinders inclusively, and second, seeking
alternately from the beginning to ending cylinders with convergence towards the middle.
Versions Category
The Versions help category lists the version numbers of the subtests that are used by your Dell Diagnostics program.

NOTE: Tape drives sold by Dell come with their own operating software and documentation. After you install a tape drive,
refer to the documentation that came with the drive for instructions on installing and using the tape drive software.

Connecting Drives
When you install a drive, you connect two cables—a DC power cable and an interface cable—to the back of the drive. Your drive’s power input
connector (to which you connect the DC power cable) resembles the connector shown in Figure 13.
Figure 13. Power Cable Connector
1 Power input connector
2 Power cable

The drive’s interface connector is a card-edge connector or a header connector, as shown in Figure 14.
Figure 14. Drive Interface Connectors

1 Card-edge connector on drive
2 Notch
3 Interface cables
4 Colored strip
5 Header connector on drive

When you attach the interface cable to a drive, be sure to match the colored strip on the cable to pin 1 of the drive’s interface connector. For the
location of pin 1 on the drive’s interface connector, see the documentation that came with the drive.
When you disconnect an interface cable from the system board, be sure to press in on the locking tabs on the cable connector before you
disconnect the cable. When you attach an interface cable to the system board, be sure that the locking tabs snap into place so that the cable is
firmly attached to the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the
other connector (see Figure 14). Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored strip along one edge of the
cable) goes to the pin-1 end of the connector.
The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or card.
NOTICE: When you connect an interface cable, do not reverse the interface cable (do not place the colored strip away from pin 1 of
the connector). Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.

This section provides a procedure for troubleshooting the ports on your computer's I/O panel and the equipment connected to them, such as a
printer, scanner, or other peripheral device.
You can also use this procedure to test I/O ports on expansion cards. However, you should first complete the procedures in "Troubleshooting
Expansion Cards" to verify that the card is configured and installed correctly.
If a system error message indicates a port problem or if equipment connected to a port seems to perform incorrectly or not at all, the source of the
problem may be any of the following:
l

A faulty connection between the I/O port and the peripheral device

A faulty cable between the I/O port and the peripheral device

A faulty peripheral device

Incorrect settings in System Setup

Incorrect settings in the system's configuration files

Faulty I/O port logic on the system board
NOTE: With certain modems installed, the Serial Port test group subtests may fail because the modem appears to the diagnostics as a
serial port, but it cannot be tested as a serial port. If you have a modem installed and you experience a serial port test failure, remove
the modem and run the diagnostic tests again.

Troubleshooting Basic I/O Functions
If a system error message indicates an I/O port problem or the device connected to the port does not function properly, follow these steps in the
order indicated until the problem is resolved:
1. Enter System Setup and verify that the settings for the Serial Port 1, Serial Port 2, and Parallel Port options are set to Auto.
2. Insert the Dell Diagnostics media into the appropriate drive, reboot the system, and run the Serial/ Infrared Ports test group and/or the
Parallel Ports test group in the Dell Diagnostics.
If any of the tests fail, the system board may be faulty. See "Getting Help" for instructions on obtaining technical assistance.
If the problem persists, go to "Troubleshooting a Parallel Printer" or "Troubleshooting a Serial I/O Device," depending on which device appears to
be malfunctioning.

Troubleshooting a Parallel Printer
If the information in "Troubleshooting Basic I/O Functions" indicates that the problem is with a parallel printer, perform the following steps in the
order indicated until the problem is resolved:
1. Reinstall the printer device driver.
See the documentation for the printer and for your operating system for instructions on reinstalling the printer driver.
2. Turn off the parallel printer and computer, replace the parallel printer interface cable with a known working cable, and turn on the parallel
printer and computer.
If the problem is resolved, the original printer cable was faulty.
3. Run the parallel printer's self-test.
If the test fails, the printer is faulty.

If the problem still is not resolved, the system board may be faulty. See "Getting Help" for instructions on obtaining technical assistance.

Troubleshooting a Serial I/O Device
If the information in "Troubleshooting Basic I/O Functions" indicates that the problem is with a device connected to one of the serial ports, perform
the following steps in the order indicated until the problem is resolved:
1. Attach the serial device to the other serial port (for example, if it is currently connected to serial port 1, attach the device to serial port 2).
If the problem is resolved, the serial port on the system board is faulty. See "Getting Help" for instructions on obtaining technical assistance.
2. If the faulty device has a detachable serial cable, replace the serial cable.
If the problem is resolved, the serial cable was faulty.
3. Replace the faulty serial device.
If the problem is still not resolved, the system board may be faulty. See "Getting Help" for instructions on obtaining technical assistance.>

Installing an EIDE Hard-Disk Drive in a Small-Form-Factor
Chassis

Installing an EIDE Hard-Disk Drive in a Mini Tower Chassis

Installing an EIDE Hard-Disk Drive in a Low-Profile Chassis

General Information About EIDE Hard-Disk Drives
The small-form-factor and low-profile chassis support a single enhanced integrated drive electronics (EIDE) hard-disk drive in the hard-disk drive
bay. In the mini tower chassis, you can install up to two EIDE drives (one of which must be 1 inch high or less) in the hard-disk drive bracket below
the drive cage. The first EIDE drive is installed in the 1-inch (lower) drive bay labeled "HD1"; a second drive is installed in the 1.6-inch bay labeled
"HD2."
EIDE Drive Addressing
All EIDE devices require that you configure the cable select setting, which assigns master and slave status to devices according to their position
on the interface cable. You usually configure a drive for cable select by setting a jumper or switch, depending on the drive. Refer to the drive
documentation in your upgrade kit for information on configuring devices for the cable select setting. When you connect two EIDE devices to a
single EIDE interface cable and configure them for the cable select setting, the device attached to the last connector on the interface cable is the
master or boot device (drive 0) and the device attached to the middle connector on the interface cable is the slave device (drive 1).
With the two EIDE interface connectors on the system board, your system supports up to four EIDE devices in the mini tower chassis; the smallform-factor and low-profile chassis support up to two EIDE devices. EIDE hard-disk drives should be connected to the EIDE interface connector
labeled "IDE1." (Always connect EIDE tape drives and CD-ROM drives to the EIDE interface connector labeled "IDE2.")

Installing an EIDE Hard-Disk Drive in a Small-Form-Factor Chassis
To install an EIDE hard-disk drive in a small-form-factor chassis, perform the following steps:

Remote Wake Up
Remote Wake Up allows you to remotely turn on a Managed PC system that is either in a sleep state or soft-off state. The ability to turn on
Managed PC systems remotely allows you to perform remote computer setup, software downloading and installation, file updates, and asset
tracking at any time.
To use the Remote Wake Up feature, each Managed PC system must contain a NIC that supports Remote Wake Up. You must also enable the
Remote Wake Up option in System Setup.
NOTE:This feature does not work if the system is shut off using a power strip or surge protector.
Remote Wake Up by a System User
With the advent of ACPI technology, Microsoft implemented a new wake-up method called pattern byte matching (PBM). When PBM is enabled,
there is the potential for a local area network (LAN) user to wake up another system that is in suspend mode. The following information explains
wake-up technology and its functionality on your Dell system under various operating systems (OS).
Remote Wake Up, also known as Wakeup On LAN, allows a network administrator to start a system remotely using a LAN signal from a server
management console. This capability provides for remote computer access after hours and on weekends when LAN traffic is typically at a
minimum.
Magic Packet Technology
Wakeup On LAN originally used a technology known as Magic Packet, which sends a data packet directly to a system. This packet consists of
data that has 16 repetitions of the system's media access control (MAC) layer address. The MAC address is unique to the network adapter in the
system so the Magic Packet wakes only the system targeted for start-up. When the network adapter receives and decodes this packet, it sends a
power management event (PME) signal to the system that brings it back to full power and boots the system.
Pattern Byte Matching Technology
PBM provides the wake-up packet for systems that support ACPI. The system downloads a series of patterns to the network adapter, and the
network adapter monitors for the arrival of these patterns in a packet. If it finds these patterns, the network adapter generates a PME signal to
wake up the system.
PBM and Magic Packet Technology Differences
PBM wake-up technology is much different from Magic Packet wake-up technology. A Magic Packet is not a regular network data packet. Magic
Packet technology starts a system when a network administrator sends the data packet from a management station.
Wake from Address Resolution Protocol (ARP) and Wake from NetBIOS name lookup patterns are available in the PBM method currently
provided in Windows 98 Second Edition (SE). ARP or NetBIOS lookup packets are standard features of network activity and can wake up
suspended systems without action from an administrator. For example, several systems may share hard-disk drives in a standard work group
scenario. If a system is in a suspend mode when someone on the network searches for that system using Network Neighborhood or clicks the
system icon, it can generate an ARP or a NetBIOS name lookup packet that wakes up the target system.
Current Wake-Up Patterns
Current wake-up patterns allowed by the Network Device Class Power Management Specification are the following:
l

Wake from ARP

Wake from NetBIOS name lookup

Directed wake packet

The specification also defines Magic Packet as a wake-up method. Wake-up technology that uses PBM is controlled by the Microsoft Windows
OS because the OS programs the patterns. Therefore, PBM only works in systems that use the Windows OS with ACPI enabled. For more
information on PBM, please refer to the Network Device Class Power Management Specification.
Changing Remote Wake Up Options
To change Remote Wake Up options, enter System Setup by pressing during the start-up boot sequence. Tables 1 and 2 define remote
wake-up functions for each Windows operating system and system power state combination.

Remote System Alert
Remote System Alert allows you to receive certain predetermined messages from the system about its operating condition. For example, the
system can transmit an alert if the computer cover is removed.
To use the Remote System Alert feature, each Managed PC system must contain an integrated NIC that supports Remote System Alert.
NOTE: This feature does not work if the system is shut off using a power strip or surge protector.
Auto Power On
Auto Power On enables you to turn on the computer system automatically on certain days of the week at a preset time. You can set Auto Power
On to turn on the system either every day or every Monday through Friday.
NOTE:This feature does not work if the system is shut off using a power strip or surge protector.
Chassis Intrusion Alerts
Chassis intrusion alerts notify you if a local or remote system's chassis has been opened.
CIM Support
CIM allows you to access system management information if your system is running Microsoft® Windows 98 or any other Windows operating

system that includes the Web-Based Enterprise Management (WBEM) core components. For information about the WBEM core components and
how to install them, see the Microsoft World Wide Web site at http:\\www.microsoft.com.
For more information about CIM support, see the Dell OpenManage Client Instrumentation Version 5.0 User's Guide installed in the Dell
Documents folder on your hard-disk drive.
Configuration Change Alerts
Configuration change alerts generate warning messages if a local or remote system has a change in hardware configuration.
Asset Info With Support for the COO MIF Standard
Asset Info uses the nonproprietary DMI standard to allow you to record and track costs related to your system. The cost-related information is
stored in the cost of ownership Management Information Format (coo.mif) file on your system's hard-disk drive. For more information about Asset
Info and the COO MIF standard, see the online "Dell OpenManage Client Instrumentation Version 5.0 User's Guide."
Remote Flash BIOS
Remote flash BIOS allows a network administrator to perform remote BIOS upgrades to systems on a network.
Remote System Configuration
Remote system configuration features allow a network administrator to change the system asset tag, boot sequence, property ownership tag, and
System Setup settings and to update the system BIOS.
Prefailure Alerts
Prefailure alerts generate warning messages about potential failures by the system DIMMs and SMART II hard-disk drives.

ENERGY STAR® Compliance
Certain configurations of Dell computer systems comply with the requirements set forth by the Environmental Protection Agency (EPA) for energyefficient computers. If the front panel of your computer bears the ENERGY STAR® Emblem (see Figure 1), your original configuration complies
with these requirements and all ENERGY STAR® power management features of the computer are enabled.
NOTES: As an ENERGY STAR® Partner, Dell Computer Corporation has determined that this product meets the ENERGY STAR®
guidelines for energy efficiency.
Any Dell computer bearing the ENERGY STAR® Emblem is certified to comply with EPA ENERGY STAR® requirements as
configured when shipped by Dell. Any changes you make to this configuration (such as installing additional expansion cards or
drives) may increase the system's power consumption beyond the limits set by the EPA's ENERGY STAR® Computers program.
Figure 1. ENERGY STAR® Emblem

The EPA's ENERGY STAR® Computers program is a joint effort between the EPA and computer manufacturers to reduce air pollution by
promoting energy-efficient computer products. The EPA estimates that use of ENERGY STAR® computer products can save computer users up
to two billion dollars annually in electricity costs. In turn, this reduction in electricity usage can reduce emissions of carbon dioxide, the gas primarily
responsible for the greenhouse effect, and sulfur dioxide and nitrogen oxides, which are the two primary causes of acid rain.
Computer users can also help to reduce electricity usage and its side effects by turning off their computer systems when they are not in use for
extended periods of time—particularly at night and on weekends.

System Memory: Dell™ OptiPlex™ GX110 System User's Guide
Overview

Removing DIMMs

Installing DIMMs

Overview
You can increase system memory up to 512 megabytes (MB) by using synchronous dynamic random-access memory (SDRAM) dual in-line
memory modules (DIMMs). Figure 9 in "Inside Your Computer" shows the location of the DIMM sockets on the system board (DIMMs must be nonerror checking and correction [ECC]).
When you add system memory, you may install DIMMs in either socket. For optimum operation, Dell recommends that you install a DIMM in socket
A first (closest to the processor) before installing a DIMM in socket B.
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at
support.dell.com.

Installing DIMMs
To upgrade memory, perform the following steps.
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their
electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before you upgrade memory,
see the other precautions in "Safety First—For You and Your Computer. "
1. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."
2. If necessary, remove any DIMMs that occupy sockets in which you plan to install the upgrade DIMMs.
3. Install the upgrade DIMMs.
a. Locate the plastic securing clips at each end of the socket (see Figure 1).
b. Press the clips outward until they snap open.
c. Press the DIMM straight into the slot running down the center of the socket until the securing tabs snap into place around the ends
of the DIMM.
Figure 1. Installing a DIMM
1 Securing clips (2)
2 Slot

4. Replace the computer cover, and reconnect your computer and peripherals to their electrical outlets and turn them on.
NOTE: After you remove and replace the cover, the chassis intrusion detector causes the following message to appear on the
screen at the next system start-up:
ALERT! Cover was previously removed.
The system detects that the new memory does not match the existing system configuration information and generates the following
message:
The amount of system memory has changed.

Strike the F1 key to continue, F2 to run the setup utility
5. Press to enter System Setup, and check the value for System Memory.
The system should have already changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is
correct, skip to step 7.
6. If the memory total is incorrect, turn off and disconnect your computer and peripherals from their electrical outlets. Remove the computer
cover, rotate the power supply, and check the installed DIMMs to make sure that they are seated properly in their sockets. Then repeat steps
3, 4, and 5.
7. Reset the chassis intrusion detector by changing Chassis Intrusion to Enabled or Enabled-Silent.
NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting
the chassis intrusion detector.
8. When the System Memory total is correct, press to exit System Setup.
9. Run the Dell Diagnostics to verify that the DIMMs are operating properly.

Removing DIMMs
To remove a DIMM, press the securing clips outward simultaneously until the DIMM disengages and pops out slightly from the socket (see Figure
2).

None. Remove the drive from the system.
This should be done only after you have
backed up the data.

When errors occur during a boot routine that cannot be reported on the monitor, your computer may emit a series of beeps that identify the
problem. The beep code is a pattern of sounds: for example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3)
means that the computer was unable to read the data in nonvolatile random-access memory (NVRAM). This information is invaluable to the Dell
support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of the Diagnostics Checklist found in "Getting Help," and then look it up in Table 2. If you are
unable to resolve the problem by looking up the meaning of the beep code, use the Dell Diagnostics to identify a more serious cause. If you are still
unable to resolve the problem, see "Getting Help" for instructions on obtaining technical assistance.

Precautionary Measures
Before you perform any procedures in this manual, take a few moments to read the following caution for your personal safety and to prevent
damage to the system from ESD.
CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT
Before you start to work on the system, perform the following steps in the sequence listed:
1. Turn off the computer and all peripherals.
2. Disconnect the computer and peripherals from their AC power sources. Also, disconnect any telephone or telecommunication lines
from the computer. Doing so reduces the potential for personal injury or shock.
3. If you are disconnecting a peripheral from the computer or are removing a component from the system board, wait 10 to 20 seconds
after disconnecting the computer from AC power before disconnecting the peripheral or removing the component to avoid possible

damage to the system board.
4. Wear a wrist grounding strap, and clip it to an unpainted metal surface, such as the padlock loop on the back of the chassis. If a wrist
grounding strap is not available, touch any unpainted metal surface on the back of the computer or on the computer chassis, such as
the power supply, to discharge any static charge from your body before touching anything inside the computer. While you work,
periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal
components. Also avoid touching components or contacts on a card and avoid touching pins on a chip.
5. Verify that the auxiliary power indicator on the system board is not on. If it is on, you may need to wait 10 to 30 seconds for it to go out
(see Figure 20).

Your microprocessor socket is a zero insertion force (ZIF) socket with a lever-type handle that secures the chip in, or releases it from, the
socket.
To remove the chip, pull the microprocessor-socket release lever straight out until the chip is released (see Figure 28). Then remove the chip
from the socket. Leave the release lever extended so that the socket is ready for the new microprocessor.

2 Release lever
3 Microprocessor socket

CAUTION: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: Positioning the microprocessor chip incorrectly in the socket can permanently damage the chip and the computer when
you turn on the system.
NOTICE: Be careful not to bend any of the pins when unpacking the microprocessor. Bending the pins can permanently damage
the microprocessor.
8. Unpack the new microprocessor.
If any of the pins on the chip appear to be bent, see your Installation and Troubleshooting Guide for instructions on obtaining technical

assistance.
9. Align the pin-1 corner of the microprocessor chip with the pin-1 corner of the microprocessor socket (see Figure 28).
NOTE: Identifying the pin-1 corners is critical to positioning the chip correctly.

The pin-1 corner of the microprocessor is the squared off corner (see Figure 28).
10. Install the microprocessor chip in the socket (see Figure 28).
If the release lever on the microprocessor socket is not all the way out, move it to that position now.
With the pin-1 corners of the chip and socket aligned, align the pins on the chip with the holes in the socket. Set the chip lightly in the socket
and make sure all pins are headed into the correct holes. Because your system uses a ZIF microprocessor socket, there is no need to use
force (which could bend the pins if the chip is misaligned). When the chip is positioned correctly, it should seat itself in the socket with
minimal pressure.
When the chip is fully seated in the socket, pivot the microprocessor-socket release lever back toward the socket until it snaps into place,
securing the chip.

the folded end of the clip to snap the clip over the tab on the bottom edge of the socket.

14. Replace the fan assembly and secure it with two thumbscrews. Then connect the fan power cable to the FAN connector on the system
board .
15. Install the microprocessor fan cable connector to the FAN connector on the system board.
16. Replace the computer cover, and then reconnect your computer and peripherals to their power sources and turn them on.
As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in
the System Setup program.
17. Enter the System Setup program, and confirm that the Microprocessor option correctly identifies the installed microprocessor.
18. Run the Dell Diagnostics to verify that the new microprocessor operates correctly.

Getting Started
If you need to set up your computer system yourself (rather than having it set up by a network administrator), see "Getting Started" in the System
Information Guide that accompanied your system for instructions on connecting cables and turning on your system for the first time.
After you correctly connect all the cables to your system and turn it on, see the setup guide for your operating system to complete its installation.
When the operating system is installed, you can connect peripheral devices, such as a printer, or install application programs not already installed
by Dell.

Connecting Peripheral Devices
Figure 1 shows the connectors on the back of your computer for attaching external devices.
Figure 1. I/O Ports, Connectors, and Indicators

1 Parallel port connector
2 Mouse connector
3 USB connectors
4 Link integrity indicator (see "Integrated NIC Connector")
5 Activity indicator (see "Integrated NIC Connector")
6 Integrated NIC connector
7 Video connector
8 Serial port 2 connector
9 Keyboard connector
10 Serial port 1 connector
When you connect external devices to your computer's back panel, follow these guidelines:
l

Check the documentation that accompanied the device for specific installation and configuration instructions.
For example, you must connect most devices to a particular input/output (I/O) port or connector to operate properly. Also, external
devices like a mouse or printer usually require you to load device drivers into system memory before they will work.

Always attach external devices while your computer is turned off. Then turn on the computer before turning on any external devices, unless
the documentation for the device specifies otherwise. (If the computer does not seem to recognize the device, try turning on the device
before turning on the computer.)
NOTICE: When you disconnect external devices from the back of the computer, wait 5 seconds after turning off the
computer before you disconnect any devices to avoid possible damage to the system board.

Parallel Port Connector

The integrated parallel port uses a 25-pin D-subminiature connector on the computer's back panel.
This I/O port sends data in parallel format (where eight data bits, or one byte, are sent simultaneously over eight separate lines in a single cable).
The parallel port is used primarily for printers.
The default designation of your computer's integrated parallel port is LPT1. Port designations are used, for example, in software installation
procedures to identify the port to which your printer is attached, thus telling your software where to send its output. (An incorrect designation
prevents the printer from printing or causes scrambled print.)
NOTE: The integrated parallel port is automatically disabled if the system detects an installed expansion card containing a parallel port
configured to the same address as specified in Parallel Port in System Setup.
Mouse Connector
Your system uses a Personal System/2 (PS/2)-compatible mouse. The mouse cable attaches to a 6-pin miniature Deutsche Industrie Norm (DIN)
connector on the back panel of your computer. Turn off the computer and any attached peripherals before connecting a mouse to the computer.
A PS/2-compatible mouse works as does an industry-standard serial mouse or bus mouse except that it has its own dedicated connector, which
frees up the serial ports and does not require an expansion card.
Mouse driver software gives the mouse priority with the microprocessor by issuing interrupt request (IRQ) 12 whenever you move the mouse. The
drivers also pass along the mouse data to the application that is in control. If you have the Microsoft® Windows® 98, Windows 95, or Windows
NT® 4.0 operating system, Dell already installed the necessary mouse drivers on your hard-disk drive. If you need to reinstall the mouse drivers,
see "Mouse Drivers" for instructions.
USB Connectors
Your system contains two Universal Serial Bus (USB) connectors for attaching USB-compliant devices. USB-compliant devices are typically
peripherals such as keyboards, mice, printers, and computer speakers.
If you reconfigure your hardware, you may need pin number and signal information for the USB connectors.
Integrated NIC Connector
Your system has an integrated 10/100-megabit-per-second (Mbps) 3Com® Peripheral Component Interconnect (PCI) 3C905C-TX Ethernet
network interface controller (NIC). The NIC provides all the functions of a separate network expansion card and supports both the 10BASE-T and
100BASE-TX Ethernet standards.
The NIC includes a Remote Wake Up feature that enables the computer to be started by a special local area network (LAN) signal from a server
management console. Remote Wake Up provides remote computer setup, software downloading and installation, file updates, and asset tracking
after hours and on weekends when LAN traffic is typically at a minimum.
The NIC connector on the computer's back panel has the following indicators (see Figure 1):
l

A yellow activity indicator flashes when the system is transmitting or receiving network data. (A high volume of network traffic may make this
indicator appear to be in a steady "on" state.)
A dual-colored link integrity indicator, which lights up green when there is a good connection between a 10-Mbps network and the NIC, or it
lights up orange when there is a good connection between a 100-Mbps network and the NIC. When the green indicator is off, the computer is
not detecting a physical connection to the network.

Video Connector
The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graphics array (VGA)-compatible
monitor to your system.
Serial Port Connectors
The serial ports use 9-pin D-subminiature connectors on the back panel. These ports support devices such as external modems or plotters that
require serial transmission (sending one bit of data at a time over one line).
The default designations for these integrated serial ports are COM1 for serial port 1 and COM2 for serial port 2. Port designations are used in
software installation procedures to identify the port used by a device—for example, to specify the port used by a modem when you install
communications software.
The system contains a reconfiguration feature to reassign the serial port's designation if you add an expansion card containing a serial port using
this designation.
If you set the system’s integrated serial ports to Auto in System Setup and add an expansion card containing a serial port configured to a specific
designation, the computer automatically maps (assigns) the integrated ports to the appropriate COM setting as necessary.
Before you add a card with a serial port, check the documentation that accompanied your software to make sure that the software can be mapped
to the new COM port designation.
Keyboard Connector

Your system uses a PS/2-style keyboard. The keyboard cable attaches to a 6-pin miniature DIN connector on the back panel of your computer.
Network Cable Requirements
Your computer's NIC connector (an RJ45 connector located on the back panel) is designed for attaching an unshielded twisted pair (UTP) Ethernet
cable. Press one end of the UTP cable into the NIC connector until the cable snaps securely into place.
Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on your network
configuration.

Hard-Disk Drive Access Indicator
The hard-disk drive access indicator lights up when a hard-disk drive is reading data from or writing data to the drive.
Reset Button
The reset button allows you to reboot (restart) your system without having to turn the power off and then on again. Rebooting the system in this
manner reduces stress on system components. However, be sure that you have saved and closed all open files and application programs (if
possible) to avoid losing any data. Then perform an orderly shutdown of the operating system (see your operating system documentation for
instructions).

Power Indicator
The power indicator on the front of the computer has a light-emitting diode (LED) that illuminates in two different colors and blinks or remains solid
to indicate several different states. See "Diagnostic LEDs" for a description of each of these states.
Power Button
The power button controls the system's AC input power.
The Microsoft Windows 98 and Windows 98 Second Edition (SE) operating systems let you configure the function of the power button through the
Advanced Configuration and Power Interface (ACPI) feature (see Table 1).
NOTICE: To turn off your computer system, perform an orderly system shutdown using the operating system menu when possible.

Diskette-Drive Access Indicator
The diskette-drive access indicator lights up when the drive is reading data from or writing data to a diskette. Wait until the access indicator turns
off before removing a diskette from the drive.
Cover Release Button
On the back of the chassis, slide the upper half of the padlock ring to the left. Then press the cover release button to remove the computer cover.

Chassis Intrusion
An integrated chassis intrusion alarm displays the status of the system chassis intrusion monitor. If the chassis has been opened, the setting
changes to Detected and the following message appears during the boot sequence at system start-up:
Alert! Cover was previously removed.
Use System Setup to reset the alarm so that future intrusions are detected.

Security Cable Slot and Padlock Ring
On the back of the computer are a security cable slot and padlock ring (see Figure 5, Figure 6, Figure 7, or Figure 8 in "Inside Your Computer") for
attaching commercially available antitheft devices. Security cables for personal computers usually include a segment of galvanized cable with an
attached locking device and key. To prevent unauthorized removal of your computer, loop the cable around an immovable object, insert the locking
device into the security cable slot on the back of your computer, and lock the device with the key provided. Complete instructions for installing this
kind of antitheft device are usually included with the device.
NOTES: Antitheft devices are of differing designs. Before purchasing such a device, make sure it works with the cable slot on your
computer.
The small-form-factor chassis has a padlock ring that slides in and out of the back cover. To use the ring, pull it into the extended
position.

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If
your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption
programs.
Your Dell system is shipped to you without the system password feature enabled. If system security is a concern, operate your system only with
system password protection.
You can assign a system password, as described in "Assigning a System Password," whenever you use System Setup. After a system password
is assigned, only those who know the password have full use of the system.
When System Password is set to Enabled, the computer system prompts you for the system password just after the system boots. See "Using
Your System Password to Secure Your System" for more information.
To change an existing system password, you must know the password (see "Deleting or Changing an Existing System Password"). If you assign
and later forget a system password, you must remove the computer cover to change a jumper setting that disables the system password feature
(see "Disabling a Forgotten Password"). Note that you erase the setup password at the same time.
NOTICE: If you leave your system running and unattended without having a system password assigned, or if you leave your
computer unlocked so that someone can disable the password by changing a jumper setting, anyone can access the data stored on
your hard-disk drive.
Assigning a System Password
Before you can assign a system password, you must enter System Setup and check the System Password option.
When a system password is assigned, the setting shown in System Password is Enabled. When the system password feature is disabled by a
jumper setting on the system board, the setting shown is Disabled. You cannot change or enter a new system password if either of these options
is displayed.
When no system password is assigned and the password jumper on the system board is in the enabled position (its default setting), the option
shown for the System Password option is Not Enabled. Only when System Password is set to Not Enabled can you assign a system
password, using the following procedure:
1. Verify that Password Status is set to Unlocked.
For instructions on changing the setting for Password Status, see "Password Status."
2. Highlight System Password, and then press the left- or right-arrow key.
The option heading changes to Enter Password, followed by an empty 32-character field in square brackets.
3. Type your new system password.
You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field. The password assignment
operation recognizes keys by their location on the keyboard, without distinguishing between lowercase and uppercase characters. For
example, if you have an M in your password, the system recognizes either M or m as correct.
Certain key combinations are not valid. If you enter one of these combinations, the speaker emits a beep.
To erase a character when entering your password, press the key or the left-arrow key.
NOTE: To escape from the field without assigning a system password, press the key or the key
combination to move to another field, or press the key at any time prior to completing step 5.
4. Press .
If the new system password is less than 32 characters, the whole field fills with placeholders. Then the option heading changes to
Verify Password, followed by another empty 32-character field in square brackets.
5. To confirm your password, type it a second time and press .
The password setting changes to Enabled. Your system password is now set; you can exit System Setup and begin using your
system. Note, however, that password protection does not take effect until you reboot the system by pressing the reset button or by
turning the system off and then on again.
Using Your System Password to Secure Your System
Whenever you either turn on your system or press the reset button, or when you reboot the system by pressing the key
combination, the following prompt appears on the screen when Password Status is set to Unlocked:
Type in the password and
- press to leave password security enabled.
- press to disable password security.
Enter password:
If Password Status is set to Locked, the following prompt appears:
Type the password and press .
After you type the correct system password and press , your system boots and you can use the keyboard and/or mouse to operate your
system as usual.
NOTE: If you have assigned a setup password (see "Using the Setup Password Feature"), the system accepts your setup password as
an alternate system password.
If you enter a wrong or incomplete system password, the following message appears on the screen:
** Incorrect password. **
Enter password:
If you again enter an incorrect or incomplete system password, the same message appears on the screen.
The third and subsequent times you enter an incorrect or incomplete system password, the system displays the following message:
** Incorrect password. **
Number of unsuccessful password attempts: 3
System halted! Must power down.
The number of unsuccessful attempts made to enter the correct system password can alert you to an unauthorized person attempting to use your
system.
Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete system password is entered.
NOTE: You can use Password Status in conjunction with System Password and Setup Password to further protect your system from
unauthorized changes.
Deleting or Changing an Existing System Password
To delete or change an existing system password, perform the following steps:
1. Enter System Setup by pressing , and verify that Password Status is set to Unlocked.
2. Reboot your system to force it to prompt you for a system password.
3. When prompted, type the system password.

4. Press to disable the existing system password, instead of pressing to continue with the normal operation of your
system.
5. Confirm that Not Enabled is displayed for the System Password option of System Setup.
If Not Enabled appears in the System Password option, the system password has been deleted. If you want to assign a new
password, continue to step 6. If Not Enabled is not displayed for the System Password option, press to reboot the system,
and then repeat steps 3 through 5.
6. To assign a new password, follow the procedure in "Assigning a System Password."

Using the Setup Password Feature
Your Dell system is shipped to you without the setup password feature enabled. If system security is a concern, you should operate your system
with setup password protection.
You can assign a setup password, as described in "Assigning a Setup Password," whenever you use System Setup. After you assign a setup
password, only those who know the password have full use of System Setup. See "Operating Your System With A Setup Password Enabled" for
more information.
To change an existing setup password, you must know the setup password. If you assign and later forget a setup password, you need to remove
the computer cover to change a jumper setting that disables the setup password feature (see "Disabling a Forgotten Password"). Note that you
erase the system password at the same time.
Assigning a Setup Password
You can assign a setup password only if Setup Password is set to Not Enabled. To assign a setup password, highlight Setup Password and
press the left- or right-arrow key. The system prompts you to enter and verify the password. If a character is illegal for password use, the system
emits a beep.
NOTES: The setup password can be the same as the system password.
If the two passwords are different, the setup password can be used as an alternate system password. However, the system password
cannot be used in place of the setup password.
After you verify the password, the Setup Password setting changes to Enabled. The next time you enter System Setup, the system prompts you
for the setup password.
A change to Setup Password becomes effective immediately (rebooting the system is not required).
Operating Your System With a Setup Password Enabled
If Setup Password is set to Enabled, you must enter the correct setup password before you can modify the majority of the System Setup options.
When you start System Setup, the System Setup screen appears with Setup Password highlighted, prompting you to type the password.
If you do not enter the correct password, the system lets you view, but not modify, the System Setup screen.
NOTE: You can use Password Status in conjunction with Setup Password to protect the system password from unauthorized
changes.
Deleting or Changing an Existing Setup Password
To delete or change an existing setup password, perform the following steps:
1. Enter System Setup.
2. Highlight Setup Password and press the left- or right-arrow key to delete the existing setup password.
The setting changes to Not Enabled.
3. If you want to assign a new setup password, perform the steps in "Assigning a Setup Password."

Disabling a Forgotten Password
If you forget your system or setup password, you cannot operate your system or change settings in System Setup until you remove the computer
cover, change the password jumper setting to disable the passwords, and erase the existing passwords.
To disable a forgotten password, perform the following steps.

CAUTION: Before you remove the computer cover, see "Safety First—For You and Your Computer."
1. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."
2. Remove the jumper plug from the PSWD jumper to disable the password feature.

AC Power Recovery
AC Power Recovery determines what happens when AC power is restored to the system.
When Off is selected, the system remains off when AC power is restored. When On is selected, the system starts up when AC power is restored.
When Last is selected, the system returns to the AC power state existing at the time that AC power was lost. If the system is on when AC power is
lost, the system starts up when AC power is restored. If the system is off when AC power is lost, the system remains off when AC power is
restored.

Asset Tag
Asset Tag displays the customer-programmable asset tag number for the system if an asset tag number is assigned. You can use the Asset Tag
utility, which is included with your software support utilities, to enter an asset tag number up to ten characters long into nonvolatile random-access
memory (NVRAM).

Auto Power On
Auto Power On allows you to set the time and days of the week to turn on the computer system automatically. You can set Auto Power On to turn
on the system either every day or every Monday through Friday.
NOTE: This feature does not work if you turn off your system using a power strip or surge protector.
Time is kept in a 24-hour format (hours:minutes). To change the start-up time, press the right-arrow key to increase the number in the highlighted
field or press the left-arrow key to decrease the number. If you prefer, you can type numbers in both fields.
The default for Auto Power On is Disabled.

Boot Sequence
Boot Sequence enables you to set the order of the devices from which the system attempts to boot.
The term boot refers to the system's start-up procedure. When turned on, the system "bootstraps" itself into an operational state by loading into
memory a small program, which in turn loads the necessary operating system. Boot Sequence tells the system where to look for the files that it
needs to load.
To set the boot device order, press to access the field's pop-up options menu. Press the up- and down-arrow keys to move through the list
of devices. Press the spacebar to enable or disable a device (enabled devices appear with a check mark). Press plus (+) or minus (–) to move a
selected device up or down the list. The following subsections describe typical boot devices.
Diskette Drive A:
Selecting Diskette Drive A: as the first device causes the system to try booting from drive A first. If the system finds a diskette that is not bootable

in the drive or finds a problem with the drive itself, it displays an error message. If it does not find a diskette in the drive, the system tries to boot
from the next device in the boot sequence list.
Hard-Disk Drive
Selecting Hard-Disk Drive causes the system to attempt to boot first from the hard-disk drive and then from the next device in the boot sequence
list.
IDE CD-ROM Device
Selecting IDE CD-ROM Device causes the system to try booting from the CD-ROM drive first. If the system finds a CD that is not bootable in the
drive or finds a problem with the drive itself, it displays an error message. If it does not find a CD in the drive, the system tries to boot from the next
device in the boot sequence list.
MBA UNDI
Selecting MBA UNDI allows the system to boot from the network server. The MBA UNDI option appears under Boot Sequence only if the
Network Interface Controller option is set to On w/MBA. If the Network Interface Controller option is set to On or Off, set it to On w/MBA and then
press to save the change and reboot the system. MBA UNDI then appears under Boot Sequence.
When you select this option, the system prompts you to press at the Dell logo screen during system boot. A menu then appears
that allows you to select PXE, RPL, BootP, or NetWare as the active boot mode. If a boot routine is not available from the network server, the
system tries to boot from the next device in the boot sequence list.

CPU ID
CPU ID provides the manufacturer's identification code for the installed microprocessor.

CPU Speed
CPU Speed indicates the processor speed at which your system boots.
Press the left- or right-arrow key to toggle the CPU Speed option between the resident microprocessor's rated speed (the default) and a lower

NOTE: Tape drives are not reflected in the Diskette Drive A and Diskette Drive B options. For example, if you have a single diskette
drive and a tape drive attached to the diskette/tape drive interface cable, set Diskette Drive A to match the characteristics of the
diskette drive and set Diskette Drive B to Not Installed.

Integrated Devices
Integrated Devices configures the following devices integrated with the system board:
l

Network Interface Controller

Mouse Port

Serial Port 1 and Serial Port 2

Parallel Port

IDE Drive Interface

Diskette Interface

USB Emulation

PC Speaker

Primary Video Controller

Video DAC Snoop

Press to configure these options as explained in the following subsections.
Network Interface Controller
Network Interface Controller determines whether the integrated NIC is On, Off, or On w/ MBA. The default is On. If you select On w/ MBA, you
are prompted to press at the Dell logo screen during system boot. A menu then appears that allows you to select PXE, RPL,
BootP, or NetWare as the active boot mode.
Mouse Port
Mouse Port enables or disables the system's integrated Personal System/2 (PS/2)-compatible mouse port. Disabling the mouse allows an
expansion card to use interrupt request (IRQ)12.
Serial Port 1 and Serial Port 2
Serial Port 1 and Serial Port 2 configure the system's integrated serial ports. You can set these options to Auto (the default) to automatically
configure a port, to a particular designation (COM1 or COM3 for Serial Port 1; COM2 or COM4 for Serial Port 2), or to Off to disable the port.
If you set a serial port to Auto and add an expansion card containing a port configured to the same designation, the system automatically remaps
the integrated port to the next available port designation that shares the same IRQ setting as follows:
l

COM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is remapped to COM3 (I/O address 3E8h).

COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is remapped to COM4 (I/O address 2E8h).
NOTE: When two COM ports share an IRQ setting, you can use either port as necessary, but you may not be able to use them both at
the same time. If you are using the Microsoft® Windows® 95 or IBM® OS/2® operating system, you cannot use both serial ports at the
same time. If the second port (COM3 or COM4) is also in use, the integrated port is turned off.

Parallel Port
Parallel Port configures the system's integrated parallel port. Press to configure the Parallel Port options explained in the following
subsections.
Mode

You can set this option to PS/2, EPP, ECP, AT, or Off to disable the port.
Set this option according to the type of peripheral device connected to the parallel port. To determine the correct mode to use, see the
documentation that came with the device.
I/O Address

This option determines the I/O address used by the parallel port and appears except when Mode is set to Off. You can set I/O Address to 378h
(the default), 278h, or 3BCh.
NOTE: You cannot set the parallel port to 3BCh if you are in extended parallel port (EPP) mode.
DMA Channel

This option determines the direct memory access (DMA) channel used by the parallel port and appears only when Mode is set to ECP. The
available options are DMA 1, DMA 3, and Off.
IDE Drive Interface
IDE Drive Interface enables or disables the system's integrated enhanced integrated drive electronics (EIDE) hard-disk drive interface.

With Auto (the default) selected, the system turns off the integrated EIDE interface when necessary to accommodate a controller card installed in
an expansion slot.
As part of the boot routine, the system first checks for a primary hard-disk drive controller card installed in an expansion slot. If no card is found, the
system enables the integrated EIDE interface to use IRQ14 and IRQ15.
If a primary controller is detected on the expansion bus, the integrated EIDE interface is disabled.
Selecting Off disables the integrated EIDE interface.
Diskette Interface
Diskette Interface controls the operation of the system's integrated diskette drive controller.
With Auto (the default) selected, the system turns off the integrated diskette drive controller when necessary to accommodate a controller card
installed in an expansion slot.
With Read Only selected, nothing can be written to any diskette drives and tape drives using the system's integrated diskette/tape drive controller.
(The system can still read from the drives.) When Read Only is selected, Auto (whereby the system turns off the integrated diskette drive
controller as necessary) is also in effect.
Selecting Off turns off the integrated diskette/tape drive controller; this setting is used primarily for troubleshooting purposes.
USB Emulation
USB Emulation determines whether the system basic input/output system (BIOS) controls Universal Serial Bus (USB) keyboards and mice.
When On is selected, the system BIOS controls USB keyboards and mice until a USB driver is loaded by the operating system. When Off is
selected (the default), the system BIOS does not control USB keyboards and mice, though they function during the boot routine. Set USB
Emulation to Off if you are using a PS/2-compatible keyboard and mouse.
PC Speaker
PC Speaker determines whether the integrated speaker is On (the default) or Off. A change to this option takes effect immediately (rebooting the
system is not required).
Primary Video Controller
Primary Video Controller determines which video controller to use when the system boots. When Auto is selected, the system uses a video
expansion card, if one is installed, or the onboard video controller if a video expansion card is not installed. When Onboard is selected, the
system uses the onboard video controller even if a video expansion card is installed.
Video DAC Snoop
Video DAC Snoop lets you correct video problems that may occur when you use certain video expansion cards. The default is Off. If you are
using a video expansion card and problems such as incorrect colors or blank windows occur, set Video DAC Snoop to On.

Keyboard NumLock
Keyboard NumLock determines whether your system boots with the Num Lock mode activated on 101- or 102-key keyboards (it does not apply
to 84-key keyboards).
When Num Lock mode is activated, the rightmost bank of keys on your keyboard provides the mathematical and numeric functions shown at the
tops of the keys. When Num Lock mode is turned off, these keys provide cursor-control functions according to the label on the bottom of each key.

PCI IRQ Assignment
PCI IRQ Assignment specifies which IRQ lines are assigned to the Peripheral Component Interconnect (PCI) devices installed in the computer.
Press to configure these devices. Then select the device whose IRQ line you want to change, and press the plus (+) or minus (–) key to
scroll through the available IRQ lines. Normally you do not need to change the IRQ lines assigned to PCI devices unless a particular device, device
driver, or operating system requires a specific IRQ line already in use by a PCI device.

Primary Drive n and Secondary Drive n
Primary Drive n identifies drives attached to the primary EIDE interface connector (labeled "IDE1") on the system board; Secondary Drive n
identifies drives connected to the secondary EIDE interface connector (labeled "IDE2"). Use the secondary EIDE interface connector for EIDE
CD-ROM and EIDE tape drives.
NOTES: For all devices obtained from Dell that use the integrated EIDE controller, set the appropriate Drive option to Auto.

You must have an EIDE device connected to the primary EIDE interface if you have an EIDE device connected to the secondary EIDE
interface.
The following settings identify the type of EIDE devices installed in the computer:
l

Auto (use this setting for all EIDE devices from Dell)

Off

User 1 or User 2

A specific drive-type number

To choose a setting for each option, press to access the field's pop-up settings menu. Then type characters from the keyboard or press
the left- or right-arrow key to cycle through the settings.
A drive-type number specifies the parameters of a hard-disk drive, based on a table recorded in the system's basic input/output system (BIOS).
NOTE: Operating systems that bypass the system BIOS may not obtain optimum hard-disk drive performance.
If You Have a Problem
If the system generates a drive error message the first time you boot your system after you install an EIDE drive, it may mean that your particular
drive does not work with the automatic drive-type detect feature. If you suspect that your problem is related to drive type, try entering your drive-type
information in one of the following ways:
l

If you know the drive-type number
Use the drive-type number you found in the documentation that came with the drive, or if the drive was installed by Dell when you
purchased your system, access the Manufacturing Test Report from the Dell Accessories folder.
To set the drive-type number in System Setup, highlight the appropriate drive option (Primary Drive 0 or Primary Drive 1) and type
the correct drive-type number. If you prefer, you can press the right- or left-arrow key to increase or decrease, respectively, the drivetype number until the correct one is displayed.

If you do not know the drive-type number
The Drive 0 and Drive 1 options display the following parameters for each drive:
¡
¡
¡
¡
¡

Drive Type is the drive-type number for the selected hard-disk drive.
Capacity (automatically calculated by the system) indicates the number of millions of bytes of storage provided by the drive.
Cylinders is the number of logical cylinders.
Heads indicates the number of logical heads in the drive.
Sectors is the number of logical sectors per track.

If none of the supported drive types match the parameters of your new drive, you can enter your own parameters. To do so, highlight the Drive 0
option and type u to display User 1. You can then press the right- or left-arrow key to switch between the User 1 and User 2 settings (only two
user-defined drive types are allowed). Then press the key to highlight each of the parameter fields in succession, and enter the appropriate
number for each field.
NOTE: You can use the User 1 and User 2 drive types for both the Primary and Secondary Drive 0 and Drive 1 options. However, if
you select the User 1 or User 2 drive type, you may not obtain optimum hard-disk drive performance. Also, you cannot use the User 1
and User 2 drive types for hard-disk drives with a storage capacity that is greater than 528 megabytes (MB).

Remote Wake Up
Remote Wake Up allows you to set the Remote Wake Up feature to On or Off. You must reboot your system before a change takes effect.

Report Keyboard Errors
Report Keyboard Errors enables or disables reporting of keyboard errors during the power-on self-test (POST), which is a series of tests that
the system performs on the hardware each time you turn on the system or press the reset button.
This option is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these situations,
selecting Do Not Report suppresses all error messages relating to the keyboard or to the keyboard controller during POST. This setting does not
affect the operation of the keyboard itself if a keyboard is attached to the computer.

System Data

The following information about the system is displayed in the system data area of the System Setup screen:
l

The microprocessor type and BIOS level.

The size of the integrated level 2 (L2) cache.

The system's five-character service tag number, which was programmed into NVRAM by Dell during the manufacturing process. Refer to this
number during technical assistance or service calls. The service tag number is also accessed by certain Dell support software, including the
diagnostics software.

System Date
System Date resets the date on the computer's internal calendar.
Your system automatically displays the day of the week corresponding to the settings in the month, day-of-month, and year fields.
To change the date, press the left- or right-arrow key to select a field, and then press plus (+) or minus (–) to increase or decrease the number. If
you prefer, you can type numbers in the month, day-of-month, and year fields.

System Memory
System Memory indicates the entire amount of installed memory detected in your system. After you add memory, check this option to confirm that
the new memory is installed correctly and is recognized by the system.

System Security
System Security configures the following password and chassis intrusion options:
l

System Password

Password Status

Setup Password

Chassis Intrusion

CPU Serial Number

Press to configure these options as explained in the following subsections.
System Password
System Password displays the current status of your system's password security feature and allows you to assign and verify a new password. No
one can assign a new password unless the current status is Not Enabled, which is displayed in bright characters.
The System Password option has the following settings:
l

Not Enabled (the default)

Enabled

Disabled by Jumper
NOTE: See "Using the System Password Feature" for instructions on assigning a system password and using or changing an existing
system password. See "Disabling a Forgotten Password" for instructions on disabling a forgotten system password.

Password Status
When Setup Password is set to Enabled, Password Status allows you to prevent the system password from being changed or disabled at
system start-up.
To lock the system password, you must first assign a setup password in Setup Password and then change the Password Status option to
Locked. When Setup Password has a password assigned and Password Status is set to Locked, the system password cannot be changed
through the System Password option and cannot be disabled at system start-up by pressing .
To unlock the system password, you must enter the setup password in Setup Password and then change the Password Status option to
Unlocked. When the option is set to Unlocked, you can disable the system password at system start-up by pressing . Then change

the password through the System Password option.
Setup Password
Setup Password lets you restrict access to System Setup in the same way that you restrict access to your system with the system password
feature. The settings are:
l

Not Enabled (the default)

Enabled

Disabled by Jumper
NOTE: See "Using the Setup Password Feature" for instructions on assigning a setup password and using or changing an existing
setup password. See "Disabling a Forgotten Password" for instructions on disabling a forgotten setup password.

Chassis Intrusion
Chassis Intrusion displays the status of the system chassis intrusion monitor and can be set to Enabled, Enabled-Silent, or Disabled. The
default is Enabled.
If the computer cover is removed while the intrusion monitor is set to Enabled, a Desktop Management Interface (DMI) event is generated, the
setting changes to Detected, and the following message appears during the boot routine at the next system start-up:
Alert! Cover was previously removed.
If the computer cover is removed while the intrusion monitor is set to Enabled-Silent, a DMI event is generated and the setting changes to
Detected, but the alert message does not appear during the boot sequence at the next system start-up.
If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no messages appear.
To reset the Detected setting, enter System Setup during the system's POST. In the Chassis Intrusion option, press the left- or right-arrow key to
select Reset, and then choose Enabled, Enabled-Silent, or Disabled.
NOTE: When the setup password is enabled, you must know the setup password before you can reset the Chassis Intrusion option.
CPU Serial Number
CPU Serial Number determines whether the microprocessor serial number (if any) is provided to programs that request it. When Enabled is
selected, the system provides the microprocessor serial number to programs that request it. When Disabled is selected, the system never
provides the microprocessor serial number.

System Time
System Time resets the time on the computer's internal clock.
Time is kept in a 24-hour format (hours:minutes:seconds). To change the time, press the left- or right-arrow key to select a field, and then press
plus (+) or minus (–) to increase or decrease the number. If you prefer, you can type numbers in each of the fields.

Memory-Resident Programs

Installing and Configuring Software

Program Conflicts

Error Messages

Memory Address Conflicts

Input Errors

Interrupt Assignment Conflicts

Overview
Because most computers have several application programs installed in addition to the operating system, isolating a software problem can be
confusing. Software errors can also appear to be hardware malfunctions at first. Software problems can result from the following circumstances:
l

Improper installation or configuration of a program

Input errors

Device drivers that conflict with certain application programs

Memory conflicts resulting from the use of terminate-and-stay-resident (TSR) programs

Interrupt conflicts between devices

You can confirm that a computer problem is caused by software by running the System Board Devices test group as described in "Dell
Diagnostics." If all tests in the test group complete successfully, the error condition is most likely caused by software.
This section provides some general guidelines for analyzing software problems. For detailed troubleshooting information on a particular program,
see the documentation that accompanied the software or consult the support service for the software.

Installing and Configuring Software
When you obtain software, check it for viruses with virus-scanning software before installing it on your computer's hard-disk drive. Viruses, which
are pieces of code that can replicate themselves, can quickly use all available system memory, damage or destroy data stored on the hard-disk
drive, and permanently affect the performance of the programs they infect. Several commercial virus-scanning programs are available for
purchase, and most bulletin board services (BBSs) archive freely distributed virus-scanning programs that you can download with a modem.
Before you install a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its accompanying documentation and a software installation routine on its program diskette(s)
or CD(s).
The software installation routine assists you in transferring the appropriate program files to your computer's hard-disk drive. Installation instructions
may provide details about how to configure your operating system to successfully run the program. Always read the installation instructions before
running a program's installation routine. You may be instructed to modify some operating system start-up files, such as config.sys and
autoexec.bat, or the installation routine may modify start-up files automatically.
When you run the installation routine, be prepared to respond to prompts for information about how your computer's operating system is
configured, what type of computer you have, and what peripherals are connected to your computer.

Error Messages
Error messages can be produced by an application program, the operating system, or the computer. "Messages and Codes" discusses the error
messages that are generated by the system. If you receive an error message that is not listed in "Messages and Codes," check your operating
system or application program documentation.

Input Errors
If a specific key or set of keys is pressed at the wrong time, a program may give you unexpected results. See the documentation that came with
your application program to make sure the values or characters you are entering are valid.
Make sure the operating environment is set up to accommodate the programs you use. Keep in mind that whenever you change the parameters of
the computer's operating environment, you may affect the successful operation of your programs. Sometimes, after modifying the operating
environment, you may need to reinstall a program that no longer runs properly.

Memory-Resident Programs
There are a variety of utilities and supplementary programs that can be loaded either when the computer boots or from an operating system
prompt. These programs are designed to stay resident in system memory and thus always be available for use. Because they remain in the
computer's memory, memory conflicts and errors can result when other programs require use of all or part of the memory already occupied by
these TSR programs.
Typically, your operating system's start-up files (such as config.sys and autoexec.bat) contain commands to start TSR programs when you boot
your system. If you suspect that one of these TSR programs is causing a memory conflict, remove the commands that start them from the start-up
file. If the problem you were experiencing does not recur, one of the TSR programs probably created the conflict. Add the TSR commands back
into the start-up files one at a time until you identify which TSR program is creating the conflict.

Program Conflicts
Some programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot
run. Rebooting your system can confirm whether or not these programs are the cause of the problem.
Programs that use specialized subroutines called device drivers can also cause problems with your computer system. For example, a variation in
the way the data is sent to the monitor may require a special screen driver program that expects a certain kind of video mode or monitor. In such
cases, you may have to develop an alternative method of running that particular program—the creation of a boot file made especially for that
program, for example. Call the support service for the software you are using to help you with this problem.

Memory Address Conflicts
Memory address conflicts occur when two or more devices try to access the same address in the upper memory blocks (UMB). For example, if a
network expansion card and an expanded-memory page frame are assigned an overlapping block of addresses, a memory address conflict
arises. As a result, when you try to log in to the network, the operation fails.
To resolve this type of conflict, you can change the address of one of the devices. For example, in the case of the network expansion card and
expanded-memory page-frame address conflict, you can move the network card to an address block in the range of CC000h through D0000h. To
reassign the expansion card's address block, refer to the documentation for the card.

Interrupt Assignment Conflicts
Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for
the default IRQ-line setting for each installed expansion card. Then consult Table 1 to configure the card for one of the available IRQ lines.
NOTE: Table 1 lists default IRQ settings. In systems with Plug and Play capabilities, you can modify the default settings. If you install a
Plug and Play card in a Plug and Play system, the system automatically selects an open IRQ line if any are available. If you install a
non-Plug and Play or legacy card, you may need to run the ISA Configuration Utility to determine the current IRQ settings and to find an
available IRQ line.

NOTE: The low-profile chassis and its optional stand are shown in Figure 1. The optional stand for the small-form-factor chassis differs
slightly in shape, but the process for removing or replacing the stand is the same as for the low-profile chassis.
To attach the optional stand to the small-form-factor or low-profile chassis, perform the following steps:
1. Turn the computer onto its right side so that the drive bays are at the bottom.
2. Fit the stand onto what was the left side of the computer.
Position the stand as shown in Figure 1. Align the large round hole in the stand with the securing button on the side of the cover, and
align the captive thumbscrew in the stand with the screw hole in the cover.
As you lower the stand into place, make sure that the locator pin (see Figure 1) fits into the corner hole of the hole pattern as shown.
When the stand is in place, tighten the thumbscrew.
3. Rotate the computer so that the stand is at the bottom and the drives are at the top.

Overview
Each time you turn on your computer system or press the reset button, the system compares the hardware installed in the system to the hardware
listed in the system configuration information stored in nonvolatile random-access memory (NVRAM) on the system board. If the system detects a
discrepancy, it generates error messages that identify the incorrect configuration settings. The system then prompts you to enter System Setup to
correct the setting.
You can use System Setup as follows:
l

To change the system configuration information after you add, change, or remove any hardware in your system

To set or change user-selectable options—for example, the time or date on your system

You can view the current settings at any time. When you change a setting, in many cases you must reboot the system before the change takes
effect.
After you set up your system, run System Setup to familiarize yourself with your system configuration information and optional settings. Dell
recommends that you print the System Setup screens (by pressing the key) or record the information for future reference.
Before you use System Setup, you need to know the kind of diskette drive(s) and hard-disk drive(s) installed in your computer. If you are unsure of
this information, see the Manufacturing Test Report that was shipped with your system and is located in the Dell Accessories folder.

Entering System Setup
To enter System Setup, perform the following steps:
1. Turn on your system.
If your system is already on, shut it down and then turn it on again.
2. When the Press to Enter Setup window appears in the upper-right corner of the screen, press .
If you wait too long and your operating system begins to load into memory, let the system complete the load operation; then shut down the system
and try again.
NOTE: To ensure an orderly system shutdown, consult the documentation that accompanied your operating system.

System Setup Screen
The System Setup screen displays the current setup and configuration information and optional settings for your system. Information on the
System Setup screen is organized in four areas (see Figure 1 for typical examples):
l

Title — The box at the top of all screens lists the system name.
System data — The two boxes below the title box display your system processor, level 2 (L2) cache, service tag, and the version number of
the basic input/output system (BIOS).
Options — The main area of the screen is a scrollable window containing options that define the installed hardware in your computer and the
power conservation and security features for your computer.
Fields next to the options contain settings or values. You can change those values that appear bright on the screen. Options or values that
you cannot change (because they are determined or calculated by the computer) appear less bright.

Key functions — The line of boxes across the bottom of all screens lists keys and their functions within System Setup.
