OS every time it is turned on. If you want to clear the system conguration, please
temporarily short these two pins to clear data by using a metal object.

You can clear CMOS by touching two pins once with a metal object while the system is
o. Avoid clearing the CMOS while the system is on; it will damage the mainboard.
