1-4 Chapter 1: Product introduction
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.
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 default
setting for each parameter.
