Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board with an external battery power supply to preserve the system configuration data. With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration, please temporarily short these two pins to clear data by using a metal object.
