2.3.1
Clear CMOS (JP1)
This jumper (3x1-pin p=2.54mm) allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system setup parameters by
erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM
data in CMOS, which includes system setup information such as system passwords.
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Remove the onboard battery.
3.
Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip on pins 2-3
for about 5~10 seconds, then move the clip back to pins 1-2.
4.
Re-install the battery.
5.
Plug the power cord and turn ON the computer.
6.
Hold down the <Del> key during the boot process and enter BIOS setup to re-enter
data.
2.3.2
