5.1.1

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
includes system setup information such as system passwords.
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 to 10 seconds, and then move the cap back to pins 1–2.
3. Plug in the power cord and turn ON the computer.
4. Hold down the <F2> key during the boot process and enter the BIOS setup to re-enter
data.
CAUTION
Except when clearing the RTC RAM, never remove the cap on the
CLRTC jumper default position. Removing the cap causes system
boot failure!
NOTE: If the steps above do not help, remove the onboard battery and move the jumper again
to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
