1.
Clear RTC RAM (3-pin CLRTC1)
This jumper allows you to clear the CMOS memory system setup parameters by
erasing the CMOS Real Time Clock (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. 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 CLRTC jumper default
position. Removing the cap will cause system boot failure!
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.
