Chapter 1: Product introduction
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.
ASUS Instant Music Lite
This unique feature allows you to playback audio files even before entering the
operating system. Just press the ASUS Instant Music special function keys and
enjoy the music! See page 2-21.

Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
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, the 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.
