If you want to clear the system configuration, use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions below to clear the data:
- Turn off the PC and unplug the power cord.
- Temporarily set the jumper labeled "JBAT1" to pins 2-3.
- Wait at least 6 seconds and then return the jumper to pins 1-2
