 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 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).
