1. Clear RTC RAM (CLRTC1)

This jumper allows you to clear the Real Time Clock (RTC) RAM in

CMOS. You can clear the CMOS memory of 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 RTC RAM, never remove the cap on CLRTC

jumper default position. Removing the cap will cause system boot failure!
