Set the Jumpers
Jumpers are sets of pins that can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.
