Clear CMoS Jumper: ClR_CMoS
The mother�oard uses CMOS RAM to store the �asic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go �ack to
factory default when the BIOS settings were mistakenly modified.
The steps to clear CMOS data are :
1. Turn off the computer, unplug the power cord from the power outlet.
�. Remove jumper cap from pins �-3, put it onto pins 1-� to short them. This will clear CMOS
data.
3. Return the setting to its original with pins �-3 closed.
4. Plug in the power cord to your computer and turn it on.
5. Go to BIOS Setup to configure new system as described in next chapter.
