Clear Cmos Jumper - Gigabyte GA-F2A75M-HD2 User Manual

11) COM (Serial Port Header)
The COM header can provide one serial port via an optional COM port cable. For purchasing the optional
COM port cable, please contact the local dealer.
12) CLR_CMOS (Clear 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, 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 configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).
