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.
