Memory configurations
You may install 256 MB, 512 MB, and 1 GB unbuffered ECC/non-ECC DDR2
DIMMs into the DIMM sockets.
•
For dual-channel configuration, the total size of memory module(s) installed
per channel must be the same (DIMM_A1 + DIMM_B1 = DIMM_A2 +
DIMM_B2).
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Visit the ASUS website (www.asus.com) for the latest
Qualified Vendors List.
•
When using only one DDR2 DIMM module, install it into slot DIMM_A1
only.
•
For single-channel memory configuration, start installing the DDR2 DIMMs
from slot DIMM_A1 or DIMM_B1.
•
For dual-channel memory configuration, install the DIMMs in slots
DIMM_B1 and DIMM_A1 (yellow slots); install another pair of DIMMs in
slots DIMM_B2 and DIMM_A2 (black slots).
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 benefit of manipulating this excess memory space.

Jumper
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!

BIOS setup program
This motherboard supports a programmable Low-Pin Count (LPC) 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, reconfiguring
your system, or prompted to“Run Setup.” This section explains how to configure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change the
configuration 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 reconfigure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the
LPC chip.
The LPC 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, restart the system by pressing <Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if
the first two failed.
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.
•
The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Default Settings item under the
Exit Menu. See section “2.7 Exit Menu.”
•
The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

Discard Changes
This option allows you to discard the selections you made and restore the
previously saved values. After selecting this option, a confirmation appears. Select
