Clearing the CMOS settings

caution:
Do not change any jumper setting while the computer is on. Damage to the motherboard can result.

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

In the default (normal) position the jumper is on pins 1-2.

Temporarily set the jumper to pins 2-3.
Wait 5-10 seconds and then return the jumper to pins 1-2.
On the next startup, enter BIOS setup to reset any custom BIOS settings.

Clearing the PASSWORD settings

The BIOS password is used to protect BIOS settings from unwanted changes. If you have forgotten your password you may use this jumper to clear the password settings.

To erase the BIOS password follow these steps:

Turn OFF the computer and unplug the power cord.
Find the password jumper.
Move the jumper to pins 2-3.
Plug in 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 1-2.
