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

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 •

congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS congurations).
