You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

gain. With this special feature, you can easily overclock your system to get higher system performance, and without removing
a

Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the
default setting or you can wait the AOpen “Watch Dog
