You can clear the CMOS memory of date, 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. Use a metal object such as a screwdriver to short the two pins for 5 - 10 seconds. 3. Plug the power cord and turn ON the computer. 4. Hold down the key during the boot process and enter BIOS setup to re- enter data. Except when clearing the RTC RAM, never short-circuit the CLRTC jumper. Shorting the CLRTC jumper will cause system boot failure! If the steps above do not help, remove the onboard battery and repeat steps 1 - 2 to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery. 1-10 Chapter 1: Product Introduction

Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, 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.
Use a metal object such as a screwdriver to short the two pins for 5 - 10 seconds.
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 short-circuit the CLRTC jumper. Shorting the
CLRTC jumper will cause system boot failure!
If the steps above do not help, remove the onboard battery and repeat steps 1 - 2 to clear
the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
