Clear CMOS jumper
Upon encountering an abnormal condition preventing the device from booting, the jumper can clear the BIOS content stored in
CMOS and restore default settings. To clear CMOS, short pin #1 to pin #2 for a minimum of three seconds, and then remove
the jumper to return to normal mode (replace to pins #2 and #3, default).
