ASUS Vintage-S800 barebone system

4.3 Jumpers

This section describes and illustrates the jumpers on the motherboard.

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 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. 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.

3. Plug the power cord and turn ON the computer.

4. 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 CLRTC1 jumper

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