With this motherboard, AOpen provides a very special, useful feature for overclockers. When
you power-on the system, the BIOS will check last system POST
status. If it succeeded, the
BIOS will enable “Watch Dog ABS” function immediately, and set the CPU FSB frequency by
user’s setting that stored in the BIOS. If system failed in BIOS POST, the “Watch Dog ABS” will
reset the system to reboot in five seconds. Then, BIOS will detect the CPU’s default frequency and POST again. With this special feature,
you can easily overclock your system to get higher system performance, and without removing the cover of system housing to set the
jumper to clear CMOS data when your system hanged.
