16) CLR_CMOS (Clearing CMOS Jumper)

Use this jumper to clear the CMOS values (e.g. date information and BIOS configurations) and

reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the

two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two

pins for a few seconds.

• Always turn off your computer and unplug the power cord from the power outlet before

clearing the CMOS values.

• After clearing the CMOS values and before turning on your computer, be sure to remove

the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized

Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for

BIOS configurations).
