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 jumpers to clear the Real Time Clock (RTC) RAM in CMOS. In the default (normal) position the jumper is on pins 4-6.

Clearing CMOS

To clear CMOS, follow these steps:

  1. Temporarily set jumper CLEAR_CMOS to pins 2-4.

  2. Wait 5-10 seconds and then return the jumper to pins 4-6.

  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:

  1. Turn OFF the computer and unplug the power cord.

  2. Locate the jumper labeled CLEAR_PWD. In the default (normal) position the jumper is on pins 3-5.

  3. Move the jumper on jumper CLEAR_PWD to pins 1-3 to clear password.

  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 reset the jumper to pins 3-5.

SPI Header

The motherboard may include an SPI header. This header is used during manufacturing and testing.

The header will have pins 1-2 bridged and should not be changed.
