CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
To clear CMOS, follow these steps:
  1. Temporarily set jumper Clear CMOS to pins 1-2.
  2. Wait 5-10 seconds and then return the jumper to pins 2-3.
  3. You may now restart the PC.
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 P.W.
  3. Move the jumper on jumper Clear P.W. to pins 1-2.
  4. Wait approximately 10 seconds and then return the jumper to pins 2-3.
  5. Plug in the power cord and turn ON the computer.
This connector allows qualified technicians to reload firmware into the SPI boot flash in case there is problem with the data.
This jumper should not be changed.
