Jumpers

1. Clear RTC RAM jumper
The Clear RTC RAM jumper allows you to clear the Real Time Clock (RTC) RAM
in the CMOS, which contains the date, time, system passwords, and system setup
parameters.
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
reenter data.
DO NOT remove the jumper cap from its default position except when clearing the RTC
RAM. Removing the jumper cap will cause system boot failure!
• If the steps above do not help, remove the onboard button cell battery and move the
jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall
the button cell battery.
• Due to chipset behavior, AC power off is required to enable C.P.R. function. You must
turn off and on the power supply or unplug and plug the power cord before rebooting
the system.
