This motherboard has jumpers to clear the Real Time Clock (RTC) RAM in CMOS.

Clearing the BIOS settings

Clearing CMOS

To clear CMOS, follow these steps:

Temporarily set jumper Clear CMOS (CLRTC) to pins 1-2.
Wait 5-10 seconds and then return the jumper to pins 2-3.
When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.

To erase the BIOS password follow these steps:

Turn OFF the computer and unplug the power cord.
Locate the jumper labeled Clear P.W. The jumper is found at the lower right edge of the motherboard.
Move the jumper on jumper Clear P.W. to pins 1-2.
Plug the power cord and turn ON the computer.
Hold down the F1O key during the startup process and enter BIOS setup to change or clear the password.
After changing or clearing the BIOS passwords, remember to reset the jumper to pins 2-3.
