Clearing the CMOS settings
The J4 jumper allows you to clear the date, time, and system setup parameter memories in CMOS, by erasing the RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, including system setup information.
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
  1. Turn off the PC and unplug the power cord.
  2. Move the J4 jumper cap from pins 1-2 (normal) to pins 2-3 (clear CMOS).
  3. Keep the J4 jumper cap on pins 2-3 for 5 to 10 seconds, then move it back to pins 1-2.
  4. Plug in the power cord and turn on the PC.
  5. Enter the BIOS setup to change BIOS settings.
Clearing the BIOS password
The BIOS password protects the BIOS from undesired changes. If password checking is enabled, and you need to disable it, use the following steps:
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
  1. Turn off the PC and unplug the power cord.
  2. Move the J2 jumper cap from pins 1-2 to pins 2-3.
  3. To enter BIOS setup, start the PC and press the F1 key as the PC boots.
  4. Clear or reset the BIOS password.
  5. Save the BIOS settings and turn off the PC.
  6. If desired, reactivate password checking by moving the J2 jumper cap back to pins 1-2.
