1.8.2 CMOS Clear (CMOS1)
To avoid damaging the computer, always turn off the power supply before setting
"Clear CMOS". Before turning on the power supply, set the jumper back to "3.0 V
Battery On". This jumper is used to erase CMOS data and reset system BIOS Infor-
mation.
The procedure for clearing CMOS is:
1. Turn off the system.
2. Short pin 2 and pin 3.
3. Turn on the system. The BIOS is now reset to its default setting.
