This motherboard has jumpers to clear the Real Time Clock (RTC) RAM in CMOS.
Clearing CMOS
To clear CMOS, follow these steps:
Temporarily set jumper CLR_CMOS to pins 1-2.
Wait 5-10 seconds and then return the jumper to pins 2-3.
On the next startup, enter BIOS setup to reset any custom BIOS settings.
Clearing the BIOS password settings
The BIOS password is used to protect BIOS settings from unwanted changes. If the BIOS password has been forgotten, disable password checking to enter setup and change or erase the password.
To erase the BIOS password follow these steps:
Turn OFF the computer and unplug the power cord.
Locate the jumper labeled PSWD.
Move the jumper on jumper PSWD to pins 1-2.
Plug the power cord and turn ON the computer.
Hold down the F10
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.
