Clearing CMOS
To clear CMOS, follow these steps:
  1. Temporarily set jumper JBAT1 to pins 2-3.
  2. Wait 5-10 seconds and then return the jumper to pins 1-2.
  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.
To erase the BIOS password follow these steps:
  1. Turn OFF the computer and unplug the power cord.
  2. Remove the JPWD1 jumper.
  3. Connect the power cord and turn on the PC.
  4. Enter BIOS Setup Menu, you will find the previous password is cleared.
  5. Turn off the PC and unplug the power cord.
