Clear CMOS Jumper: JCMOS1
There is a CMOS RAM onboard that has a power supply from external battery to keep
the data of system configuration. With the CMOS RAM, the system can automatically
boot OS every time it is turned on. If you want to clear the system configuration, set
the JCMOS1 (Clear CMOS Jumper ) to clear data.
