Clearing the CMOS settings

The Clear CMOS RAM (CLRRTC solder points) jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. It also allows clearing of 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 such as system passwords.
  1. Turn off the PC and unplug the power cord.
  2. Use a flat screwdriver to short the two CLRRTC solder points.
  3. Plug in the power cord and turn on the PC.
  4. Press F1 while the PC starts to enter the BIOS setup and change BIOS settings.
