2.5 Jumpers
A jumper is a metal bridge that closes an electrical circuit. It consists of two metal
pins and a small metal clip (often protected by a plastic cover) that slides over
the pins to connect them. To “close” (or turn ON) a jumper, you connect the pins
with the clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case, you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when
setting jumpers. You can congure your motherboard to match the needs of your
application by setting the jumpers.
This section illustrates the default settings and conguration options of the
jumpers, and provides instructions on how to congure your motherboard by
setting them.
