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.
