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, and
software compatibility with legacy Parallel ATA. With the integrated controller in the
SIS 964 chipset, the motherboard supports RAID0, RAID1 configuration using
SATA drives. See pages 1-19.
CrashFree BIOS 2
This feature allows you to restore the original BIOS data from a floppy disk or
support CD in case when the BIOS codes and data are corrupted. This protection
eliminates the need to buy a replacement ROM chip.
AGP 8X support
AGP 8X (AGP 3.0) is the next generation VGA interface specification that enables
enhanced graphics performance with high bandwidth speeds up to 2.12 GB/s. With
a bus of 533Mhz, AGP 8X is twice as fast as AGP 4X.
8 USB 2.0 ports
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. The higher bandwidth of USB 2.0 allows connection of

1-3
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’s previous setting for each parameter.
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.

When using PCI cards on shared slots, ensure that the drivers support “Share
IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will
arise between the two PCI groups, making the system unstable and the card
inoperable.

1.9 Jumpers
1. Clear RTC RAM (CLRTC1)
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 RAM data in CMOS, that include
system setup information such as system passwords, is powered by the
onboard button cell battery.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. 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.
3. Plug the power cord and turn ON the computer.
4. 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 CLRTC1 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 BIOS can automatically reset
parameter settings to default values.

2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56, USBPW78)
Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU
stopped, DRAM refreshed, system running in low power mode) using the
connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no
power to CPU, DRAM in slow refresh, power supply in reduced power mode).
Both jumpers are set to pins 1-2 (+5V) by default because not all computers
have the appropriate power supply to support this feature.
The USBPW12 and USBPW34 jumpers are for the rear USB ports. The
USBPW56 and USBPW78 jumpers are for the internal USB header that you
can connect to the front USB ports.
1. This feature requires a power supply that can provide at least 1A on the
+5VSB lead when these jumpers are set to +5VSB. Otherwise, the system
would not power up.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal condition or in sleep mode.
3. The rear panel USB ports (Ports 1 to 4) do not support device wake-up
from S4 sleep mode.

2.2 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 may want to change
the configuration of your computer in the future. For example, you may want to
enable the security password feature or make changes to 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. It is a menu-
driven program, which means you can scroll through the various sub-menus and
make your selections among the predetermined choices.
Because the BIOS software is constantly being updated, the following BIOS
setup screens and descriptions are for reference purposes only, and may not
exactly match what you see on your screen.

3.3 ASUS Instant Music Lite
The motherboard is equipped with a BIOS-based audio playback feature called
Instant Music Lite. This feature is supported by the onboard audio AC’97
CODEC, and requires an optical drive (CD-ROM, DVD-ROM, or CD-RW).
1. Instant Music Lite only supports CDs in audio format.

1. Connect the analog audio cable from the optical drive (CD-ROM, DVD-ROM,
or CD-RW drive) to the 4-pin CD-In connector (labeled CD1) on the
motherboard. See section “1.10 Connectors” for the connector location.
Make sure to connect the CD-ROM audio cable. Otherwise, you cannot control
the audio volume using the Instant Music Lite function keys.
