1.6 Jumpers
1.6.1 Clear CMOS (CLRTC)
This jumper 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 include
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 cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for
about 5~10 seconds, then move the cap back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the key during the boot process and enter BIOS setup to re-enter
data.
Except when clearing the CMOS, never remove the cap on the
CLRTC jumper default position. Removing the cap will cause system
boot failure!
