  2. Disable password checking.
In the default (normal) position the jumper is on pins 2-3.
Figure 3: Jumper locations
To clear CMOS, follow these steps:
  1. Temporarily set jumper CLRTC to pins 1-2.
  2. Wait 5-10 seconds and then return the jumper to pins 2-3.
  3. When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.
The BIOS password is used to protect BIOS settings from unwanted changes. If you have forgotten your password you may disable password checking.
To erase the BIOS password follow these steps:

  2. Locate the jumper labeled Clear P.W. The jumper is found at the lower right edge of the motherboard, near the SATA connectors.
  3. Move the jumper on jumper Clear P.W. to pins 1-2.
  4. Plug the power cord and turn ON the computer.
  5. Hold down the F1 key during the startup process and enter BIOS setup to change or clear the password.
  6. After changing or clearing the BIOS passwords, remember to reset the jumper to pins 2-3.
