Setting Jumper Switches
Jumpers are sets of pins connected together with jumper caps. The
jumper caps change the mainboard’s operation by changing the
electronic circuits on the mainboard. If we connect two pins with a
jumper cap, these pins are SHORT; if remove a jumper cap from
these pins, they are OPEN.
