Clear CMOS Jumper: CLR_CMOS1 ( Located near CMOS battery )
The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back 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.
2. Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them.
This will clear CMOS data.
3. Return the setting to its original with pins 2-3 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.
Clear Jumper on pins 1 & 2
- Disconnect the power cable before adjusting the jumper settings.
- Do not clear the CMOS while the system is turned on.
