Clearing BIOS settings

Resetting BIOS settings are done by moving a jumper onto a pair of pins on the motherboard. Use this section to clear settings for the CMOS RAM (sometimes referred to as Real Time Clock or RTC) or the BIOS password.
Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
This motherboard has jumpers to:
  1. Clear the Real Time Clock (RTC) RAM in CMOS. In the default (normal) position the jumper is on pins 2-3.
  2. Disable password checking.
Figure : Jumper locations

Clearing CMOS

To clear CMOS, follow these steps:
  1. To clear CMOS settings, 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.

Clearing BIOS password

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:
  1. Turn OFF the computer and unplug the power cord.
  2. Locate the jumper labeled CLPWD. The jumper is found at the top edge of the motherboard, near the DIMM sockets. In the default (normal) position the jumper is on pins 2-3.
  3. Move the jumper on jumper CLPWD to pins 1-2 to clear password.
  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.
