Chapter 1: Product introduction
1.3 Special features
1.3.1 Product Highlights
Latest processor technology
The motherboard supports the latest AMD Athlon™, Athlon™ XP and AMD
Duron™ processors via a 462-pin surface mount ZIF socket. The AMD Athlon™
and AMD Athlon™ XP processors features a 400Mhz front side bus and the
QuantiSpeed™ architecture for rapid execution of applications.
Serial ATA solution
The motherboard supports four interfaces compliant to the Serial ATA (SATA)
specification, an evolutionary replacement of the Parallel ATA storage interface.
The Serial ATA specification allows for thinner, more flexible cables with lower pin
count, reduced voltage requirement, up to 150 MB/s data transfer rate.
Serial A TA RAID
The motherboard provides a high-performance Serial ATA RAID controller that
enhance hard disk performance and data backup protection without the cost of
additional RAID cards. The onboard VIA VT8237 RAID controller provides an
additional two Serial ATA connectors for RAID 0 and RAID 1 functions.
AGP 8X support
AGP 8X (AGP 3.0) is the VGA interface specification that enables enhanced
graphics performance with maximum bandwidth speed of up to 2.12 GB/s.
S/PDIF out
The motherboard’s S/PDIF out function turns your computer into a high-end
entertainment system with digital connectivity to powerful speaker systems.
USB 2.0 technology
The motherboard implements the new Universal Serial Bus (USB) 2.0
specification, extending the connection speed from 12 Mbps on USB 1.1 to a fast
480 Mbps on USB 2.0 - supporting up to eight USB 2.0 ports. The higher
bandwidth of USB 2.0 allows connection of devices such as high resolution video
conferencing cameras, next generation scanners and printers, and fast storage
units. USB 2.0 is backward compatible with USB 1.1.
6-Channel Audio solution
The motherboard uses an onboard audio Codec that lets you enjoy high-quality
6-channel audio without having to buy advanced sound cards.

1.3.2 Unique ASUS features
ASUS Wi-Fi slot
The ASUS Wi-Fi slot is designed for the ASUS WiFi-b™ add-on card to set up an
environment for wireless LAN. The ASUS WiFi-b™ add-on card bundles the
exclusive software Access Point (AP) to save the extra cost of a stand-alone AP. In
addition, the card comes with user-friendly utilities and applications that allow quick
connection to notebooks, PDAs and other wireless LAN peripherals. See page
1-16.
AI NET solution
The Marvell® Gigabit LAN controller chipset is onboard to provide a single-chip
solution for LAN on Motherboard (LOM) applications. The controller integrates 32bit 10/100/1000BASE-T Gigabit Ethernet Media Access Control (IEEE 802.3
compliant) and Physical Layer Transceiver solution to support high performance
network applications. The controller is equipped with the Virtual Cable Tester™
(VCT) net-diagnosing utility that intelligently diagnoses and reports cable faults
from a remote location up to 100 meters. This feature helps maintain a more stable
network connection.
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the fan speeds according to the
system loading to ensure quiet, cool, and efficient operation. See page 2-26.
CrashFree BIOS 2
This feature allows you to restore the original BIOS data from the ASUS support
CD in case when the BIOS codes and data are corrupted. This protection
eliminates the need to buy a replacement ROM chip. See page 2-6.
ASUS MyLogo™
This feature present in the motherboard allows you to personalize and add style to
your system with customizable boot logos. See pages 2-28.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply reboot the system and the BIOS shows
the previous setting so users can amend the CPU setting again.
C.O.P. (CPU Overheating Protection)
With AMD® Athlon XP™ installed, the motherboard offers automatic CPU
Overheating Protection to prolong the life of the entire system. If the CPU
temperature exceeds the set criteria, the PC shuts down automatically.
1-4
Chapter 1: Product introduction
ASUS EZ Flash BIOS
With the ASUS EZ Flash, you can easily update the system BIOS even before
loading the operating system. No need to use a DOS-based utility or boot from a
floppy disk. See page 2-5.
ASUS Instant Music Lite
This unique feature allows you to playback audio files even without booting the
system to Windows™. Just press the ASUS Instant Music special function keys
and enjoy the music! See pages 2-14, 3-5
1.4 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. 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.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
5. 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 stand-by power LED. When lit, this green LED
indicates that the system is ON, in sleep mode, or in soft-off mode, 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.

lever sideways, then lift it up to a 90°100° angle.
Socket lever
Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the
CPU does not fit in completely.
3. Position the CPU above the socket
such that the CPU corner with the
gold triangle matches the base of the
socket lever.
90°-100° angle
4. Carefully insert the CPU into the
socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into the
socket to prevent bending the pins and damaging the CPU!
5. When the CPU is in place, push
down the socket lever to secure the
CPU. The lever clicks on the side tab
to indicate that it is locked.

Chapter 1: Product introduction
1.7.3 Installing a DIMM
Follow these steps to install a DIMM.
1. Unlock a DIMM socket by pressing the
retaining clips outward.
2. Align a DIMM on the socket such that the
notch on the DIMM matches the break on
the socket.
3. Firmly insert the DIMM into the socket
until the retaining clips snap back in place
and the DIMM is properly seated.
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT
force a DIMM into a socket to avoid damaging the DIMM.
1.8 Expansion slots
To install and configure an expansion card:
DDR DIMM
Unlocked
1. Install an expansion card following the instructions that came with the chassis.
2. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 2 for BIOS information.
3. Assign an IRQ to the card. Refer to the tables next page.
4. Install the drivers and/or software applications for the expansion card
according to the card documentation.
