Jumpers—A General Explanation
System-Board Jumpers
Disabling a Forgotten Password
This section provides specific information about the jumpers on the system board.
Jumpers—A General Explanation
Jumpers provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When reconfiguring the system, you may need to
change jumper settings on the system board. You may also need to change jumper settings on expansion cards or drives.
Jumpers
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The wire connects
the pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated. FigureA-1 shows an
example of a jumper.
Figure A-1. Jumpers
A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is no plug at all. When the plug is pushed down
over two pins, the jumper is referred to as jumpered. The jumper setting is often shown in text as two numbers, such as 1-2. The number 1 is printed on the
circuit board so that you can identify each pin number based on the location of pin 1.
FigureA-2 shows the location and default settings of the jumper blocks on the system board. See TableA-1 for the designations, default settings, and
functions of the system's jumpers.
System-Board Jumpers
FigureA-2 shows the location of the configuration jumpers on the system board. TableA-1 lists the function of these jumpers.
Figure A-2. System-Board Jumpers
WARNING: Make sure the system is turned off before you change a jumper setting. Otherwise, damage to the system or unpredictable results
may occur.
Table A-1. System-BoardJumperSettings

Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed in "Using the System Setup Program," in the
User's Guide. A password jumper on the system board enables these password features or disables them and clears any password(s) currently in use.
To disable a forgotten system password or setup password, perform the following steps.
1. Remove the system cover.
2. Refer to FigureA-2 for the location of the password jumper (labeled "PASSWORD") on the system board.
3. Remove the jumper plug from the PASSWORD jumper.
4. Replace the system cover, and then reconnect the system to an electrical outlet and turn it on.
The existing passwords are not disabled (erased) until the system boots with the PASSWORD jumper plug removed. However, before you assign a new
system and/or setup password, you must install the jumper plug.
5. Repeat step 1.
6. Install the jumper plug on the PASSWORD jumper.
7. Replace the system cover, and then reconnect the system and peripherals to their electrical outlets and turn them on.
8. Assign a new system and/or setup password.
To assign a new system password using the System Setup program, see "Assigning a System Password" in the User's Guide.

Installing and Configuring Software
Using Software
Because most systems 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 an application program
lInput errors
lDevice drivers that may conflict with certain application programs
lInterrupt conflicts between devices
You can confirm that a system problem is caused by software by running the system diagnostics. See "Running the System Diagnostics." If all tests in the test
group are completed successfully, the problem is most likely caused by software.
This section provides some general guidelines for analyzing software problems. For detailed troubleshooting information on a particular application program,
see the documentation that accompanied the software or consult the support service for the software.
Installing and Configuring Software
Use virus-scanning software to check newly acquired application programs and files for viruses before installing the application programs on the system's hard
drive. Viruses can quickly use all available system memory, damage and/or destroy data stored on the hard drive, and permanently affect the performance of
the application programs they infect. Several commercial virus-scanning programs are available for purchase.
Before installing an application program, read its documentation to learn how the application program works, what hardware it requires, and what its defaults
are. An application program usually includes installation instructions in its accompanying documentation and a software installation routine.
The software installation routine assists users in transferring the appropriate application program files to the system's hard drive. Installation instructions may
provide details about how to configure the operating system to successfully run the application program. Always read the installation instructions before
running an application program's installation routine.
When you run the installation routine, be prepared to respond to prompts for information about how the system's operating system is configured, what type
of system you have, and what peripherals are connected to the system.
Using Software
The following subsections discuss errors that can occur as a result of software operation or configuration.
Error Messages
Error messages can be produced by an application program, the operating system, or the system. "Indicators, Messages, and Codes" discusses the error
messages that are generated by the system. If you receive an error message that is not listed in "Indicators, Messages, and Codes," check the operating
system or application program documentation.
Input Errors
If a specific key or set of keys is pressed at the wrong time, an application program may give you unexpected results. See the documentation that came with
the application program to make sure that the values or characters you are entering are valid.
Make sure that the operating environment is set up to accommodate the application programs you use. Keep in mind that whenever you change the
parameters of the system's operating environment, you may affect the successful operation of the application programs. Sometimes, after modifying the
operating environment, you may need to reinstall an application program that no longer runs properly.
Application Program Conflicts
Some application programs may leave portions of their setup information behind, even though you have exited from them. As a result, other application
programs cannot run. Rebooting the system can confirm whether these application programs are the cause of the problem.
Device drivers, which are application programs that use specialized subroutines, can cause problems with the system. For example, a variation in the way the
data is sent to the monitor may require a special screen driver application program that expects a certain kind of video mode or monitor. In such cases, you
may have to develop an alternate method of running that particular application program—by creating a start-up file made especially for that application
program, for example. Call the support service for the software you are using to help you with this problem.
Avoiding Interrupt Assignment Conflicts
Problems can arise if two devices attempt to use the same IRQ line. To avoid this type of conflict, check the documentation for the IRQ line's default for each
installed expansion card. Then consult Table3-1 to configure the card for one of the available IRQ lines.

Inside the System

In Figure5-5, the system cover and front bezel are removed to provide an interior view of the system.
Figure 5-5. Inside the System
The system board holds the system's control circuitry and other electronic components. Several hardware options such as the microprocessor and memory are
installed directly on the system board. The system board can accommodate up to five PCI expansion cards (two cards at 64-bit/66 MHz or 64-bit/33 MHz, and
three cards at 32-bit/33 MHz).
The drive cage contains two externally accessible, 5.25-inch drive bays that provide space for up to two drives, including a CD or DVD drive and one other
device, such as a tape drive. The drive cage also provides space for up to two 1-inch IDE hard drives.
Additionally, the card guide assembly provides two additional brackets for a 3.5-inch diskette drive and a 1-inch IDE hard drive.
When you look inside the system, note the DC power cables leading from the power supply. The power cables supply power to the system board, drives, and
any expansion cards that connect to external peripheral.
The wide ribbon cables are the interface cables for internal drives. For the diskette drive, an interface cable connects the drive to an interface connector on the
system board or on an expansion card. For IDE devices, interface cables connect the devices to an IDE connector on the system board (for more information,
see "Installing Drives").
During an installation or troubleshooting procedure, you may be required to change a jumper. For information on the system board jumpers, see "Jumpers and
Connectors."

If the date and time are not correct in the System Setup program, replace the battery.
You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you
shut down the system. Therefore, you must reenter the system configuration information and reset the options each time the system boots until you replace
the battery.
The battery is a 3.0-volt (V), coin-cell battery. To remove the battery, perform the following steps.
1. Enter the System Setup program and, if possible, make a printed copy of the System Setup screens.
See "Using the System Setup Program," in the User's Guide for instructions.
2. Shut down the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3. Remove the system cover (see "Removing the System Cover and Support Beam" in "Troubleshooting Your System").
4. Remove any expansion cards that limit access to the battery (see "Removing Expansion Cards").
5. Remove the battery (see Figure6-1, for the battery location).
6. Pry the battery out of its socket with your fingers or with a blunt, nonconductive object such as a plastic screwdriver.
7. Install the new battery with the side labeled "+" facing up (see Figure6-15).
8. Replace any expansion cards that you removed in step 4 (see "Installing Expansion Cards").
Figure 6-15. Installing the Battery
NOTE: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the
System Setup program, the problem may be caused by software rather than by a defective battery.
NOTE: If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation
is not caused by a defective battery.
WARNING: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
"Safety First— For You and Your System" in "Troubleshooting Your System."
WARNING: There is a danger of a 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: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.

9. Replace the system cover, and then reconnect the system and peripherals to their power sources and turn on the system power.
10. Enter the System Setup program to confirm that the battery is operating properly.
11. Enter the correct time and date through the System Setup program's Time and Date settings.
Also reenter any system configuration information that is no longer displayed on the System Setup screens, and then exit the System Setup program.
12. To test the newly installed battery, power down and disconnect the system from the electrical source for at least an hour.
13. After an hour, connect the system to an electrical source and turn on the power.

Configuring the Boot Device
Connecting Drives
Removing and Reinstalling the Drive Cage
Adding or Replacing Hard Drives
Adding or Replacing Other Drives
Your system has six drive bays for installing the following types of drives (see Figure7-1):
lThe externally accessible drive bays at the front of the system consist of a 3.5-inch drive bay that accommodates one 3.5-inch diskette drive (standard)
and two 5.25-inch, half height drive bays that can accommodate two 5.25-inch devices— typically a CD drive and one other device, such as a tape drive.
lThere are three internally accessible 3.5-inch bays that can hold up to three 1-inch EIDE hard drives.
Figure 7-1. Drive Bays
The following sections contain general information and information that you will need in several of the installation procedures. The remaining sections address
each type of drive removal and installation.
Configuring the EIDE Subsystem
The enhanced integrated drive electronics (EIDE) subsystem includes two IDE interfaces (primary and secondary), each of which can support up to two IDE
devices such as high-capacity hard drives, CD drives, DVD drives, and tape drives.
All IDE devices should be configured for the Cable Select jumper position, which assigns master and slave status to devices by their position on the interface
cable. In this configuration, the drive attached to the last connector on the interface cable is the master or boot drive (drive 0) and the drive attached to the
middle connector on the interface cable is the slave drive (drive 1). The drive jumpers are located on the back of each IDE drive. See the drive's documentation
for instructions on setting the Cable Select jumper position.
Configuring the Boot Device
If you plan to boot the system from a hard drive, the hard drive must be attached to the primary IDE controller. The device that the system boots from is
determined by the boot order specified in the System Setup program.
The System Setup program provides options that the system uses to scan for installed boot devices. Refer to the User's Guide for information about the
System Setup program.

Connecting Drives
When installing 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 Figure7-2.
Figure 7-2. Connecting the Power Cable
Your drive's interface connector resembles the connector shown in Figure7-3.
