Clearing the CMOS settings

CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
Clear RTC RAM (3-pin CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.
  1. Turn off the PC and unplug the power cord.
  2. Move the jumper cap from pins 1-2 (Normal) to pins 2-3 (Clear CMOS). Keep the cap on pins 2-3 for about 5 to 10 seconds, then move the cap back to pins 1-2.
  3. Plug the power cord and turn on the PC.
  4. Hold down the F1 key during the startup process and enter BIOS setup to re-enter/reset any custom BIOS settings.
CAUTION:Except when clearing the RTC RAM, never remove the cap from the default position. Removing the cap will cause system boot failure!

Clearing the password settings

CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
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 PC and unplug the power cord.
  2. Move the jumper cap on jumper CLPWD to pins 1-2.
  3. Plug the power cord and turn on the PC.
  4. Hold down the F1 key during the boot process and enter BIOS setup to re-enter/reset any custom BIOS settings.
  5. After changing or clearing the BIOS passwords, turn off the PC reset the jumper to pins 2-3
