* For dual-channel memory conguration (2), you may:

• install identical DIMMs in all four sockets OR

• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow
sockets) and another identical DIMM pair in DIMM_A2 and
DIMM_B2 (black sockets)

* Always use identical DDR2 DIMM pairs for dual-channel model. For

optimum compatibility, we recommend that you obtain memory modules
from the same vendor. Visit the ASUS website (www.asus.com) for the

latest Qualied Vendors List.

Important notice on installing Windows® XP 32-bit version

If you install Windows® XP 32-bit version Operating System (OS), the limitation
of this OS version is that it may reserve a certain amount of memory space for
system devices. We recommend that you install less than 3 GB system memory
if you would like to work under Windows® XP 32-bit version OS. The excess
memory installation will not cause any usage problem, but it will not give users

the benet of manipulating this excess memory space.

1.9 Jumpers

1. Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system setup
parameters by erasing the CMOS RTC RAM data. The onboard button
cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the onboard battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins

2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

4. Reinstall the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS setup to
re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

You do not need to clear the RTC when the system hangs due to overclocking.
For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall)
feature. Shut down and reboot the system so the BIOS can automatically reset
parameter settings to default values.

2.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can update

using the provided utility described in section “2.1 Managing and updating your
BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to“Run Setup.” This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration of your computer in the future. For example, you can enable the

security password feature or change the power management settings. This

requires you to recongure your system using the BIOS Setup program so that the

computer can recognize these changes and record them in the CMOS RAM of the
SPI chip.

The rmware chip on the motherboard stores the Setup utility. When you start up

the computer, the system provides you with the opportunity to run this program.
Press <Del> during the Power-On Self-Test (POST) to enter the Setup utility;
otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, reboot the system by doing any of the
following procedures:

• Restart using the OS standard shut-down procedure.

• Press <Ctrl>+<Alt>+<Del> simultaneously.

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or
system. We recommend to always shut-down the system properly from the
operating system.

The Setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various sub-menus and make
your selections from the available options using the navigation keys.

3.3 Creating a RAID driver disk

A oppy disk with the RAID driver is required when installing Windows®

2000/XP operating system on a hard disk drive that is included in a RAID
set.

To create a RAID driver disk:

1. Place the motherboard support CD into the CD-ROM drive.

2. Select Make Disk tab.

3. From the Make Disk menu, select the RAID driver disk you want to
create or browse the contents of the support CD to locate the driver
disk utility.

For detailed descriptions on the NVIDIA® RAID conguration, refer to the
“NVIDIA® MediaShield RAID User’s Manual” found in your motherboard
support CD .

4. Insert oppy disk to oppy disk drive.

5. Follow succeeding screen information to complete process.

6. Write-protect the oppy disk to avoid computer virus infection.

To install the RAID driver:

1. During the OS installation, the system prompts you to press the F6
key to install third-party SCSI or RAID driver.

2. Press <F6> then insert the oppy disk with RAID driver into the oppy

disk drive.

3. Follow the succeeding screen instructions to complete the installation.

Due to chipset limitation, the Serial ATA ports supported by the NVIDIA

chipset doesn’t support Serial Optical Disk Drives (Serial ODD) under

DOS.
