2-18 Chapter 2: Hardware information

2.6 Jumpers

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 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 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 <Del> 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!
