When you power-on the system, the BIOS will check last system

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 without removing the cover of system housing,
and be able to set the jumper to clear CMOS data when your system hanged.
