A battery must be used to retain the motherboard configuration in CMOS RAM short 1-2
pins of JP3 to store the CMOS data.
To clear the CMOS, follow the procedure below:
1.
Turn off the system and unplug the AC power
2.
Remove ATX power cable from ATX power connector
3.
Locate JP3 and short pins 2-3 for a few seconds
4.
Return JP3 to its normal setting by shorting pins 1-2
5.
Connect ATX power cable back to ATX power connector
