2.5 Jumper Settings
NOTE:
A jumper is a metal bridge that is used to close 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/SHORT a jumper means connecting the pins of the jumper
with the plastic clip and to OPEN a jumper means removing the plastic
clip from a jumper.
The motherboard jumpers are listed below.
