2.4 Onboard jumpers
1. Clear RTC RAM jumper
The Clear RTC RAM jumper allows you to clear the Real Time Clock (RTC)
RAM in the CMOS, which contains the date, time, system passwords,
and system setup parameters.
CLRTC
PIN 1
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about
5-10 seconds.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter
BIOS setup to re-enter data.
NOTE: If the steps above do not help, remove the onboard button cell
battery and move the jumper again to clear the CMOS RTC RAM data.
After clearing the CMOS, reinstall the button cell battery.
