BasicChecks:Dell™OptiPlex™GX100SystemUser'sGuide

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:

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

lPerform the steps in "Checking Connections and Switches."

lPerform the steps in "Look and Listen."

lIf your system did not complete the boot (start-up) routine, see "Getting Help."

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

lVerify the settings in System Setup.

lRun 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).

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.

Overview

Checking Connections and Switches

Backing Up Your Files

Look and Listen

Basic Checks

System Setup

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.

NOTE: See "Controls and Indicators" and "Connecting Peripheral Devices" for the location of your computer's external connections

and switches.

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

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:

lA 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.

lA 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.

lA 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.

lA 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.

lA 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 <Num Lock> key, the

<Caps Lock> key, and the <Scroll Lock> 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™GX100SystemUser'sGuide

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

Invalid configuration information -

please run SETUP program

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.

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.

2. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."

3. Remove the battery.

See Figure 7 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

Overview

Replacing the Battery

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.

CAUTION: Before you remove the computer cover, see "Safety First — For You and Your Computer."

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™GX100SystemUser'sGuide

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.

International Dialing Codes

Click a listed country to obtain the appropriate contact numbers.

Overview

Europe Contact Numbers

International Dialing Codes

Asia and Other Regions Contact Numbers

Americas Contact Numbers

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.

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

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

Figure 14. Drive Interface Connectors

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.

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 small-

form-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:

1. If you are replacing a hard-disk drive that contains data you want to keep, be sure to make a backup of your files before you continue this

procedure.

2. Prepare the drive for installation.

NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.

NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage the drive. Instead, set the drive on a

surface, such as a foam pad, that will sufficiently cushion it.

Check the documentation for the drive to verify that it is configured for your computer system.

NOTE: On systems with hard-disk drives larger than 2 GB, create a primary partition of 2 GB and divide the remaining capacity into

partitions of 2 GB or less. For example, a system with a 2.5-GB hard-disk drive would have a primary partition of 2 GB (drive C) and a

second partition of 500 MB (drive D). Hard-disk drives must be partitioned this way because MS-DOS-based operating systems

(including Windows NT, when using a file allocation table [FAT] 16 file system) do not support drive partitions larger than 2 GB.

Safety First—For You and Your Computer

The procedures in this section require that you remove the cover and work inside your computer. While working inside your computer, do not

attempt to service the computer except as explained in this guide and elsewhere in Dell documentation. Always follow the instructions closely.

Working inside your computer is safe—if you observe the following precautions.

Before you start to work on the computer, perform the following steps in the sequence indicated:

1. Turn off the computer and all peripherals.

2. Touch an unpainted metal surface on the computer chassis, such as the metal around the card-slot openings at the back of your computer,

before touching anything inside your computer.

3. Disconnect the computer and peripherals from their electrical outlets. Doing so reduces the potential for personal injury or shock. Also

disconnect any telephone or telecommunication lines from 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.

In addition, Dell recommends that you periodically review the safety instructions in your System Information Guide.

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.

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 standby 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 standby 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:

NOTE: This feature does not work if the system is shut off using a power strip or surge protector.

lWake from ARP

lWake from NetBIOS name lookup

lDirected 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 <F2> 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.

Table 1. Network Driver Interface Specification (NDIS) 4.0 Driver

Table 2. NDIS 5.0 Driver with ACPI Enabled

Remote System Alert

Remote System Alert allows the system to send to a remote management console certain predetermined messages about its operating condition

prior to system start-up (system boot). 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.

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.

Chassis Intrusion Alerts

Chassis intrusion alerts notify you if a local or remote system's chassis has been opened.

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 remote changes to the system asset tag, boot sequence, property ownership tag, and System Setup

settings and remote updates to 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 energy-

efficient 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.

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.

Upgrading the Microprocessor

To replace the microprocessor, perform the following procedure.

1. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."

2. If you are working in the small-form-factor chassis or low-profile chassis, it may be helpful to remove the power supply.

If you are working in the mini tower chassis, it may be helpful to lay the computer on its side, and then rotate the power supply out of the way.

For instructions, see "Rotating the Power Supply Away From the System Board (Mini Tower Chassis Only)."

3. If you are working in the mini tower chassis, remove the airflow shroud.

Pull up on the release tabs (see Figure 1) while you lift and rotate the bottom of the shroud up and away from the microprocessor/heat

sink assembly. Remove the shroud tabs from the chassis hooks, and lift the shroud out of the chassis.

Figure 1. Airflow Shroud, Heat Sink Assembly, and Microprocessor



4. If you are working in the small-form-factor chassis or low-profile chassis, disconnect the cooling fan power cable from the system board

connector. Then remove the two thumbscrews securing the cooling fan to the heat sink. Lift the cooling fan from the microprocessor/heat sink

assembly.

Figure 2. Cooling Fan, Heat Sink Assembly, and Microprocessor

Upgrading the Microprocessor

NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.

CAUTION: Before you remove the computer cover, see "Safety First—For You and Your Computer."

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 15 seconds before you remove the computer cover. Also, before you upgrade the

microprocessor, see the other precautions in "Safety First—For You and Your Computer."

Shroud tabs (2)

Chassis hooks (2)

Release tabs (2)

CAUTION: The microprocessor and heat sink assembly can get extremely hot. Be sure the assembly has had sufficient time to

cool before you touch it.

5. Release the metal securing clip that holds the heat sink assembly to the microprocessor zero insertion force (ZIF) connector.

Press down on the folded part of the clip with a small screwdriver to release the clip (see Figure 3). The securing clip hooks over tabs on the

sides of the socket.

6. Remove the heat sink assembly from the microprocessor.

Figure 3. Microprocessor Heat Sink

NOTICE: Be careful not to bend any of the pins when you remove the microprocessor from its socket. Bending the pins can

permanently damage the microprocessor.

7. Remove the microprocessor from the ZIF socket.

The microprocessor socket is a ZIF socket with a lever-type handle that secures the microprocessor in, or releases it from, the socket.

NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.

To remove the microprocessor, pull the ZIF socket release lever straight out until the microprocessor is released (see Figure 4). Then

remove the microprocessor by lifting it straight up from the socket. Leave the release lever extended so that the socket is ready for

9. Align pin-1 (the beveled corner) of the microprocessor with the pin-1 corner of the microprocessor ZIF socket (see Figure 5).

Figure 5. Installing the Microprocessor Chip

NOTICE: When you place the microprocessor in the ZIF socket, be sure that all of the pins go into the corresponding holes on all

sides of the socket. Be careful not to bend any of the pins when you install the microprocessor in the ZIF socket. Bending the pins

can permanently damage the microprocessor.

NOTICE: You must position the microprocessor correctly in the socket to avoid permanent damage to the microprocessor and the

computer when you turn on the system.

10. Install the microprocessor in the ZIF socket (see Figure 5):

a. If the release lever on the microprocessor socket is not all the way out, move it to that position now.

b. With the pin-1 corners of the microprocessor and socket aligned, align the pins on the microprocessor with the holes in the

socket.

c. Lightly set the microprocessor 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 microprocessor is misaligned).

When the microprocessor is positioned correctly, press it with minimal pressure to seat it.

d. When the microprocessor is fully seated in the socket, pivot the socket release lever back toward the socket until it snaps into

place, which secures the microprocessor.

NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.

11. Unpack the heat sink included in your upgrade kit and install it:

a. Peel the release liner from the adhesive tape that is attached to the bottom of the heat sink.

the fan with the two thumbscrews.

13. Reconnect the cooling fan power cable to its system board connector.

14. If you are working in the mini-tower chassis system, replace the airflow shroud:

a. Place the airflow shroud over the processor.

b. Fit the mouth of the shroud into the alignment slot on the left side of the fan and between the fan and the power supply bracket on

the right.

c. Lift up on the pair of tabs on the sides of the shroud and lower it onto the processor/heat sink assembly until it clicks into place.

The shroud should engage the top of the processor socket.

15. Replace or rotate the power supply back into position, making sure that the securing tab snaps into position.

16. Replace the computer cover, and then reconnect your computer and peripherals to their electrical outlets and turn them on.

As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration

information in System Setup.

17. Enter System Setup and confirm that the system data area correctly identifies the type of installed microprocessor.

18. While in System Setup, reset the chassis intrusion detector by changing Chassis Intrusion to Enabled, Enabled-Silent, or Disabled.

See "Chassis Intrusion" for instructions.

19. Run the Dell Diagnostics to verify that the new microprocessor is operating correctly.

SetupandOperation:Dell™OptiPlex™GX100SystemUser'sGuide

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

When you connect external devices to your computer's back panel, follow these guidelines:

lCheck 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.

lAlways 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.

Serial port 1 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.)

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 the documentation that accompanied your Dell ResourceCD 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):

lA 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.)

lA 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

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.

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.

Controls and Indicators

Figure 2 shows the controls and indicators on the front panel of your computer.

Figure 2. Controls and Indicators

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.

For Microsoft Windows 95, the power button functions as follows:

lWhen the computer is turned off, pushing the power button turns on the computer.

lWhen the computer is turned on, pushing the power button turns off the computer.

For Microsoft Windows 98 and Windows NT, you can configure the power button's function through the basic input/output system (BIOS). If you

configure the power button, it functions as follows:

lWhen the computer is turned off, pushing the power button turns on the computer.

Hard-disk drive access indicator

Reset button

Power indicator

lWhen the computer is turned on, pushing the power button and holding it for more than 6 seconds turns off the computer.

lWhen the computer is turned on, pushing the power button and releasing it places the computer in a suspended state that you determine

through the BIOS configuration.

lWhen the computer is in the suspended state, pushing the power button and releasing it brings the computer out of the suspended state.

If the system does not turn off when you press the power button, the system may be hung. Press and hold the power button until the system turns off

completely (this process may take several seconds). Alternatively, press the reset button to reset the system and reboot. If the system is hung and

both buttons fail to function properly, unplug the AC power cable from the computer, wait for it to completely stop running, plug in the AC power

cable, and if it the system does not restart, press the power button to restart the system.

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

Press the cover release button to remove the computer cover for the small-form-factor chassis or the low-profile chassis.

On the back of the mini tower 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 3) 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.

Figure 3. Security Cable Slot and Padlock Ring

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.

Padlock ring

Security cable slot

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 <Backspace> key or the left-arrow key.

4. Press <Enter>.

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 <Enter>.

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 <Ctrl><Alt><Del> key

combination, the following prompt appears on the screen when Password Status is set to Unlocked:

Type in the password and

- press <ENTER> to leave password security enabled.

- press <CTRL><ENTER> to disable password security.

Enter password:

If Password Status is set to Locked, the following prompt appears:

Type the password and press <Enter>.

After you type the correct system password and press <Enter>, your system boots and you can use the keyboard and/or mouse to operate your

system as usual.

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.

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 <F2>, 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.

NOTE: To escape from the field without assigning a system password, press the <Tab> key or the <Shift><Tab> key

combination to move to another field, or press the <Esc> key at any time prior to completing step 5.

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.

NOTE: You can use Password Status in conjunction with System Password and Setup Password to further protect your system from

unauthorized changes.

4. Press <Ctrl><Enter> to disable the existing system password, instead of pressing <Enter> 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 <Alt> 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. Since your system is also shipped with the DMI agent enabled and

active (allowing system settings to be changed remotely), Dell strongly recommends that you enable and use the setup password feature to

prevent unauthorized changes to system settings.

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.

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.

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.

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.

NOTE: You can use Password Status in conjunction with Setup Password to protect the system password from unauthorized

changes.

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.

Refer to "System Board Jumpers" for jumper information and to Figure 8 in "Inside Your Computer" for the location of the password

jumper (labeled "PSWD") on the system board.

3. Replace the computer cover.

4. Reconnect your computer and peripherals to an electrical outlet, and then turn them on.

Booting your system with the PSWD jumper plug removed erases the existing password(s).

5. Enter System Setup, and verify that the password is disabled. Proceed to step 6 if you want to assign a new password.

6. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."

7. Replace the PSWD jumper plug.

8. Replace the computer cover, and then reconnect the computer and peripherals to an electrical outlet and turn them on.

Booting your system with the PSWD jumper installed reenables the password feature. When you enter System Setup, both password

options appear as Not Enabled, meaning that the password feature is enabled but that no password has been assigned.

9. Assign a new system and/or setup password.

To assign a new system password, see "Assigning a System Password."Toassignanewsetuppassword,see"Assigning a Setup

Password."

lParallel Port

lIDE Drive Interface

lDiskette Interface

lUSB Emulation

lPC Speaker

lPrimary Video Controller

lVideo DAC Snoop

Press <Enter> 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 <Ctrl><Alt> 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:

lCOM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is remapped to COM3 (I/O address 3E8h).

lCOM2 (I/O address 2F8h), which shares IRQ3 with COM4, is remapped to COM4 (I/O address 2E8h).

Parallel Port

Parallel Port configures the system's integrated parallel port. Press <Enter> 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.

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

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.

NOTE: You cannot set the parallel port to 3BCh if you are in extended parallel port (EPP) mode.

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 <Enter> 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.

The following settings identify the type of EIDE devices installed in the computer:

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

lOff

lUser 1 or User 2

lA specific drive-type number

To choose a setting for each option, press <Enter> 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).

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:

lIf 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 drive-

type number until the correct one is displayed.

lIf 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 <Tab> key to highlight each of the parameter fields in succession, and enter the appropriate

number for each field.

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,

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.

NOTE: Operating systems that bypass the system BIOS may not obtain optimum hard-disk drive performance.

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).

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:

lThe microprocessor type and BIOS level.

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

lThe system's seven-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

the new memory is installed correctly and is recognized by the system.

System Security

System Security configures the following password and chassis intrusion options:

lSystem Password

lPassword Status

lSetup Password

lChassis Intrusion

lCPU Serial Number

Press <Enter> to configure these options as explained in the following subsections.

System 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. Dell strongly recommends that you enable and use this feature to prevent unauthorized changes to System Setup settings.

The System Password option has the following settings:

lNot Enabled (the default)

lEnabled

lDisabled by Jumper

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.

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.

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 <Ctrl><Enter>.

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 <Ctrl><Enter>. Then change

lDisabled by Jumper

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.

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.

SoftwareChecks:Dell™OptiPlex™GX100SystemUser'sGuide

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:

lImproper installation or configuration of a program

lInput errors

lDevice drivers that conflict with certain application programs

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

lInterrupt 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

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.

Table 1. Default IRQ Line Assignments

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.

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:

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

lTo 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 <Print Screen> 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 <F2> to Enter Setup prompt appears in the upper-right corner of the screen, press <F2>.

If you wait too long and your operating system begins to load into memory, let the operating system finish loading; then shut down the system and

try again.

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:

lTitle — The box at the top of all screens lists the system name.

lSystem 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).

lOptions — 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.

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