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:

Turn OFF the computer and unplug the power cord.

Remove the onboard battery.

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.

Re-install the battery.

Plug the power cord and turn ON the computer.

Hold down the <Del> key during the boot process and enter BIOS setup to re-

enter data.

Note!

Except when clearing the RTC RAM, never remove the cap on CLRTC

jumper default position. Removing the cap will cause system boot fail-

ure!
