P/I-P55SP4 User's Manual
Using Your Mainboard
In addition to the operating instructions in your system manual,
there are a few additional things specific to the mainboard you will
need to know. These have to do with the hardware settings on the
mainboard and the system configuration record.
Hardware Settings
There are a number of hardware settings on the board. They
specify configuration options for various features. The settings are
made using something called a 'jumper'. Ajumper is a set of two or
more metal pins in a plastic base attached to the mainboard. A plas­
tic jumper 'cap' with a metal plate inside fits over two pins to create
an electrical contact between them. The contact establishes a hard­
ware setting.
Some jumpers have two pins, others have three or more. The
jumpers 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 looks.
