DIMM
Terminator
Module
To avoid damaging a DIMM and voiding its warranty, take the following precautions:
♦ Do not remove the DIMM from its antistatic package until you are ready to install it.
♦ Do not touch the metallic finger contacts.
♦ Do not bend, twist, drop, or otherwise handle the DIMM carelessly.
♦ Do not expose the DIMM to moisture or extreme temperatures.
When adding or replacing system memory on all system boards:
11
♦ On a 100 MHz FSB system board, install DIMMs in order from the lowest bank to the highest
bank, starting with ba nk 0.
♦ On a 133 MHz FSB system board, install DIMMs first in Bank 3, then in Bank 2, and finally
in Bank 0. Do not install DIMMs in Bank 1.
♦ On a 133 MHz FSB system board, do not replace DIMM terminator modules in Bank 1 with
standard DIMMs.
♦ Ensure all installed DIMMs are PC133 (133 MHz FSB system board) or PC100 (100 MHz
FSB system board), as appropriate. Do not mix DIMMs of different speeds.
♦ Use only registered DIMMs. Do not use unbuffere d DIMMs.
♦ Install DIMMs in both sockets of a bank. Do not install only one DIMM in a bank.
♦ Install the same size DIMM in both sockets of a bank. You can vary DIMM sizes from bank
to bank, but not within a bank.

CMOS/Clock Lithium Battery
The CMOS/clock lithium battery is located at the bottom of the system board, next to the lowest
expansion sockets. The battery may be hidden under installed expansion cards.
Battery
Battery replacement is not normally required. The battery has a life expectancy of 10 years with
no line power applied to the system. When line power is present, there is no drain on the battery.
If you must remove the battery, the system loses its operating parameters stored in CMOS memory.
As a result, the system BIOS parameter settings are lost. After you install a new battery, you must
reset the date and time and reconfigure the BIOS parameter settings. See Chapter 3, "BIOS
Setup," for more information on configuring BIOS parameter settings.
WARNING Turn off the system and disconnect it from AC power before changing the
battery. Damage to components can occur if the battery is shorted while AC
power is applied.
To remove the battery, push out the clip on the side of the battery holder to release the battery.
Ensure that the new battery is properly oriented before installing it (positive side facing up).
Replace the battery only with the same or equivalent type as recommended by the manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.
3 BIOS Setup
This chapter describes the BIOS Setup program and BIOS parameter settings. It also describes
how to use CMOS reset and how to update the system BIOS.
BIOS Overview
The system’s basic input/output system (BIOS) records basic system operating parameters, such as
the amount of memory, the boot sequence, and the type of video display. The BIOS is stored in
flash erasable-programmable memory (EPROM) on the system board, and reads the system
parameters in the system’s complementary metal-oxide semiconductor (CMOS) random-access
memory (RAM). When you power off the system, a lithium battery provides power to CMOS
RAM to retain the operating parameters. Each time you power on the system, the BIOS uses
stored parameters to configure system operation.
The BIOS Setup program, which is also stored in the flash EPROM on the system board, allows
you to manually change the system operat ing parameters. You can also run the BIOS Setup
program during the system’s power-on self-test (POST). For the system to operate correctly, you
should run BIOS Setup after you make any hardware cha nges to the system.

Using CMOS Reset
CMOS reset instructs the BIOS to use factory settings, clears BIOS passwords, and runs BIOS
Setup at system boot. See Chapter 2, "Components," for the location of the CMOS reset jumper
connector on the system board.
To use CMOS reset:
1. Turn off system power and disconnect the system from AC power.
2. Install a jumper on the CMOS reset connector (J29) on the system board.
3. Connect the system to AC power and start the system. BIOS Setup runs automatically.
4. Reconfigure the BIOS parameter settings as needed.
5. Go to the Exit screen and select Save Changes. Do not select Exit Saving Changes or press
F10.
6. Turn off system power (while still in BIOS Setup) and disconnect the system from AC power.
7. Remove the jumper from the CMOS reset connector (J29) on the system board.
8. Connect the system to AC power and start the system.

4 Resources
This chapter lists and describes system board resources.
ISA Interrupt Requests (IRQs)
Most Industry Standard Architecture (ISA) peripheral devices installed in the system require you
to reserve an interrupt request (IRQ). Peripheral Component Interconnect (PCI) peripheral devices
share system resources and can use the same IRQ. (See “PCI-to-ISA Interrupt Map” in this
chapter.) At least one IRQ must be unassigned for use with your system’s PCI devices.
33
IRQ
0 Reserved (timer/counter) 8 Reserved (real-time clock)
1 Reserved (keyboard controller) 9 System Management Bus / ACPI
2 Reserved (interrupt controller) 10 P CI
3 Serial ports COM 2 / COM 4 11 PCI
4 Serial ports COM 1 / COM 3 12 PS/2 mouse
5 PCI / Audio 13 Hardware Monitor
6 Reserved (floppy disk controller) 14 Primary IDE
7 Parallel port LPT 1 15 Secondary IDE
To reserve an IRQ for an installed peripheral device:
1. Start or restart the system and run the BIOS Setup program.
2. Go to the Advanced Screen and select the PCI Configuration parameter.
3. Select and reserve the appropriate IRQ.
4. Save the changes and exit from BIOS Setup.
The system has a limited number of available IRQs. To install more ISA peripheral devices than
you have available IRQs, you must disable one unused system port for each excess ISA device,
unless the device does not require an IRQ.
Some older PCI device driver software cannot share an interrupt, which is a violation of the current
PCI specification. If you install a device that uses such driver software, you must free an IRQ for
the device to work in the system.

This chapter lists and describes POST tasks and beep codes, and error messages produced by the
system board.
POST Tasks and Beep Codes
When you turn on power to or restart the system, the system’s basic input/output system (BIOS)
runs a number of tasks. These power-on self test (POST) tasks test and initialize the system
hardware and then boot the operating system from the system’s primary hard disk drive.
At the beginning of each POST task, the BIOS sends a test-point error code to input/output (I/O)
port 80h. Programmers and technicians use this code during troubleshooting to establish at what
point the system failed and what POST task was being run. If the BIOS detects a terminal error
condition, it issues a terminal-error beep code, attempts to display the error code on screen, and
stops POST. If the system hangs before the BIOS can process the error, the value displayed at I/O
port 80h is the last POST task run. In this case, the error code does not disp lay on screen.
The following is a list of test point codes written to I/O port 80h at the start of each task. The tasks
are arranged by test point number in the BIOS code. The beep codes are listed for terminal errors,
and are short groups of beeps that represent the terminal error code in four two-bit groups.

If the BIOS detects error 2C, 2E, or 30 (base 512 KB RAM error), it displays an additional wordbitmap (xxxx) indicating the address line or bits that failed. For example, 2C 0002 means address
line 1 (bit one set) has failed; 2E 1020 means data bits 12 and 5 (bits 12 and 5 set) have failed in
the lower 16 bits.
