1.3 Special features
1.3.1 Product Highlights
With the SiS
®
648FX chipset, the motherboard supports 800MHz front side bus
and the Intel
®
Prescott CPU. In addition to supporting high-bandwidth DDR400,
unique MuTIOL technology increases the bus speed between the northbridge and
southbridge to 1GB/sec for enhanced system performance.

1.3.2 Unique ASUS features
CrashFree BIOS
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 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 2-2.
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 shut down and reboot the system, and
BIOS automatically restores the CPU previous setting for each parameter.
Instant Music Lite
This unique feature allows you to playback audio CDs even without booting the
system to Windows
®
. Just press the ASUS Instant Music special function keys and
enjoy the music! See details on pages 2-15 and 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 discharge
any static electricity by touching the metal surface of the system chassis.
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.

1.6.2 Installing the CPU
Follow these steps to install a CPU.
1. Locate the 478-pin ZIF socket on the motherboard.
Make sure that the socket lever is lifted up to 90°-100° angle; otherwise, the
CPU does not fit in completely.
2. Unlock the socket by pressing the
lever sideways, then lift it up to a 90°-
100° angle.

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.
3. Position the CPU above the socket
such that its marked corner matches
the base of the socket lever.
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!

1.7.2 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.
• Install only qualified DDR DIMMs on this motherboard. See Table 1.
