carrying data in packets. This high speed interface is software compatible
with existing PCI specifications. See page 1-15 for details.
Serial ATA II technology
The motherboard supports the Serial ATA 3 Gb/s technology through
the Serial ATA interfaces. The Serial ATA II 3 Gb/s specification provides
twice the bandwidth of the current Serial ATA products with a host of
new features, including Native Command Queueing (NCQ), and Power
Management (PM) Implementation Algorithm. Serial ATA allows for thinner,
more flexible cables with lower pin count, reduced voltage requirement. See
page 1-22 for details.
The Hot Swap function is supported only in RAID mode.
S/PDIF digital sound ready
The motherboard supports the S/PDIF Out function through the S/PDIF
interfaces on the rear panel and at midboard. The S/PDIF technology
turns your computer into a high-end entertainment system with digital
connectivity to powerful audio and speaker systems. See page 1-23 for
details.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0
specification, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0
is backward compatible with USB 1.1. See pages 1-17, 1-19 and 1-23 for
details.

1.3.2 Innovative ASUS features
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 2-3 for details.
ASUS CrashFree BIOS 2
This feature allows you to restore the original BIOS data from the 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 for
details.
ASUS MyLogo2™
This feature allows you to personalize and add style to your system with
customizable boot logos. See page 2-35 for details.
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 the BIOS automatically restores the CPU default
setting for each parameter.

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 firmware 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 or the firmware hub.
The firmware 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>+<Del>, 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.”
