9) COM (Serial Port Header)
The COM header can provide one serial port via an optional COM port cable. For purchasing the op-
tional COM port cable, please contact the local dealer.
10) 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 clear-
•
ing the CMOS values.
After system restart, go to BIOS Setup to load factory defaults (select Load Optimized De-
•
faults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS
configurations).
