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. Open: Normal Short: Clear CMOS Values •• 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). - 20 -

12) 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 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 configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS
configurations).
Open: Normal
Short: Clear CMOS Values
