17) CLR_CMOS (Clear 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, 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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).
