(3). JP1: CMOS Memory Clearing Header
This header uses a jumper to clear the CMOS memory. Short pin 2 and pin 3 only when you
want to clear the CMOS memory. The default setting is pin 1 and pin 2 shorted for normal
operation.
NOTE: Turn the power off first (including the +5V standby power) before clearing the
CMOS memory. Failing to do so may cause your system to work abnormally or malfunction.
