1. Clear RTC RAM (2-pin CLRTC)

This header allows you to clear the CMOS RTC RAM data of the system setup

information such as date, time, and system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Use a metal object such as a screwdriver to short the two pins.

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.

If the steps above do not help, remove the onboard battery and short the two pins again to

clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.

2. RTC Battery header (2-pin BATT_CON)

This header is for the lithium CMOS battery.
