Clearing Cmos Jumper; Serial Port Header - Gigabyte GA-Q35M-S2 User Manual

15) COMB (Serial Port Header)
The COMB header can provide one serial port via an optional COM port cable. For purchasing the
optional COM port cable, please contact the local dealer.
16) 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
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).
