4.6 Jumper

This section describes and illustrates the jumper on the motherboard.

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 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.
