2.6 Jumpers
1. Clear RTC RAM (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 RAM
data in CMOS, that include system setup information such as system
passwords, is powered by the onboard button cell battery.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper 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. Replace 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.
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R.
(CPU Parameter Recall) feature. Shut down and reboot the system so
BIOS can automatically reset parameter settings to default values.
