JP1 (Clear CMOS)

In case the embedded board fails to boot due to user’s improper BIOS setting, this jumper can be

used to clear the CMOS data and reset the system BIOS information. To clear the CMOS

contents, shunt pins 2 and 3 for a few seconds, and then reinstall the jumper clip back to pins 1

and 2.

If the “CMOS Settings Wrong” message displays during the boot up process, you may then try to

correct the fault by pressing the F1 to enter the CMOS Setup menu. You may then enter the

correct CMOS setting, Load Optimal Defaults, or Load Failsafe Defaults. Save your changes and

exit the CMOS Setup menu.
