The mainboard provides jumpers for setting some mainboard functions.
This section will explain how to change the settings of the mainboard
functions using the jumpers.
Clear CMOS: CLEAR_CMOS
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 that include system setup information such
as system passwords.

Clear CMOS setting ON ON OFF
Keep CMOS setting OFF ON ON
To erase the RTC RAM:
• Turn OFF the computer and unplug the power cord.
• Remove the onboard battery
• Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep cap
on pins 2-3 for about 5~10 seconds, then move the cap back to
pins 1-2.
• Replace the battery.
• Plug the power cord and turn ON the computer.
• Hold down the <Del> key during the boot process and enter BIOS
• Setup to re-enter data.
WARNING: Except when clearing the RTC RAM, never remove the
cap on CLEAR_CMOS jumper default position. Removing the cap
will cause system boot failure. Clearing the CMOS while the system
is on may damage the mainboard.
