Jumpers

1.
Clear RTC RAM (3-pin CLRTC)
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 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
reenter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
2.
Intel
ME jumper (3-pin DIS_ME)
®
This jumper allows you to enable or disable the Intel
function. Set this jumper to pins 1-2 to enable (default) the Intel
ME function and to pins 2-3 to disable it.
Disable the Intel
1-4
If the steps above do not help, remove the onboard battery and move the jumper
again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the
battery.
You do not need to clear the RTC when the system hangs due to overclocking. For
system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature.
Shut down and reboot the system so the BIOS can automatically reset parameter
settings to default values.
