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.
