Clearing the BIOS 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.

Clearing CMOS

To clear CMOS, follow these steps:
  1. Temporarily set jumper CLR_CMOS_HP to pins 2-3.
  2. Wait 5-10 seconds and then return the jumper to pins 1-2.
  3. When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.

Clearing the 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 CLEAR_PWD. The jumper is found at the lower right edge of the motherboard, near the SATA connectors.
  3. Move the jumper on jumper CLR_PWD to pins 2-3.
  4. Plug the power cord and turn ON the computer.
  5. Hold down the F10 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 turn off the computer and reset the jumper to pins 1-2.
