1.6.1 Clear CMOS (JCMOS1)
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 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 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 <Del> key during the boot process and enter BIOS setup to re-enter data.

Chapter 1: Product Introductions
Except
when clearing the RTC RAM, never remove the cap on CLRTC
jumper
default
position. Removing the cap will cause system boot failure!
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 the BIOS can automatically
reset
parameter
settings to default values.
