1.3.2 Unique ASUS features
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.
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.
ASUS MyLogo2™
This new feature present in the motherboard allows you to personalize and add
style to your system with customizable boot logos. See pages 2-26.

Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1.
2.
3.
4.
5.
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.

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.

Jumpers
1. Clear RTC RAM (CLRTC)
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 the 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 its previous values.

BIOS Setup program
This motherboard supports a programmable firmware chip that you can update
using the provided utility described in section “4.1 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 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 of 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+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 menudriven program, which means you can 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.”
The BIOS setup screens shown in this chapter are for reference purposes only,
and may not exactly match what you see on your screen.
