Take note of the following precautions before you install motherboard components
or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any
component.

• Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that
the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you
should shut down the system and unplug the power cable before removing or
plugging in any motherboard component. The illustration below shows the location
of the onboard LED.

1.7.1 Overview

The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory

Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched

differently to prevent installation on a DDR DIMM socket.

The gure illustrates the location of the DDR2 DIMM sockets:

Channel Sockets

Channel A DIMM_A1

Channel B DIMM_B1

1-8 Chapter 1: Product introduction

1.7.2 Memory congurations

You may install 256MB, 512MB, 1GB, and 2GB unbuffered non-ECC DDR2

DIMMs into the DIMM sockets.

• For dual-channel conguration, the total size of memory module(s) installed

per channel must be the same (DIMM_A1 = DIMM_B1).

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the

same vendor. Refer to the DDR2 Qualied Vendors List on next page for

details.

• If you are using a Windows 32-bit operating system (e.g. 32-bit Windows
XP, 32-bit Windows Vista) without the Physical Address Extension (PAE)

support, the system will allocate a certain amount of memory space for
system devices.

• We recommend that you install only a maximum of 3GB system memory

when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;

however, the system can not use this excess memory space and the

system will display less than the total size of physical memory installed.

• This motherboard does not support memory modules made up of 128 Mb

chips or double-sided x16 memory modules. .

1.7.3 DDR2 Qualied Vendors List

The following table lists the memory modules that have been tested and qualied

for use with this motherboard. Visit the ASUS website (www.asus.com) for the

latest DDR2 DIMM modules for this motherboard.

Make sure to choose the right QVLs (Qualied Vendors List) from ASUS

website according to the version of your mother board. Refer to your Printed
Circuit Board (PCB) for version information.

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

The rmware hub 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 rst 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 “2.8 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.
