18) CLR_CMOS (Clearing CMOS Jumper)

Use this jumper to clear the CMOS values (e.g. date information and BIOS congurations) and reset the

CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to tem-

porarily 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 clear-

ing 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 De-

faults) or manually congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS

congurations).
