If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function, this header
is called a jumper in this manual.
• A Jumper is usually but not necessarily given a "JpX" legend.
• In the Jumper setting diagram, all jumper pins covered with
black marks stand for closed pins with jumper cap.

make sure the power is off before changing any jumper
settings. Otherwise, mainboard could be damaged.
