Chapter 1 Hardware Configuration 7
1.5 Jumper settings
1.5.1 Introduction
This section tells how to set the jumpers to configure your card. It
gives the card default configuration and your options for each jumper.
After you set the jumpers and install the card, you will also need to
run the BIOS Setup program (discussed in Chapter 3) to configure the
serial port addresses, floppy/hard disk drive types and system operat-
ing parameters. Connections, such as hard disk cables, appear in
Chapter 2.
For the locations of each jumper, see the board layout diagram
depicted earlier in this chapter.
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal cap (often protected by a
plastic cover) that slides over the pins to connect them. To "close" a
jumper, connect the pins with the cap. To "open" a jumper, remove
the cap. Sometimes a jumper will have three pins, labeled 1, 2 and 3.
In this case you connect either pins 1 and 2 or 2 and 3.
You may find a pair of needle-nose pliers useful for setting the
jumpers.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative before
you make any changes.
