2.1. Jumper Setting Summary
Regarding hardware settings on the board. They specify configuration
options for various features. The settings are made using something
called a "Jumper". A jumper is a set of two or more metal pins in a
plastic base attached to the mainboard. A plastic jumper "cap" with a
metal plate inside fits over two pins to create an electrical contact
between them. The contact establishes a hardware setting.
Some jumpers have two pins, other have three or more. The jumper are
sometimes combined into sets called jumper "blocks", where all the
jumpers in the block must be set together to establish a hardware setting.
The next figures show how this locks.
