Setting the Jumpers
If you need to change any jumper settings, follow these steps:

Refer to the illustration on page 4-6 to locate the jumpers.

If there are any option cards installed in your computer, you
need to remove them to access the jumpers. See page 4-18.

A jumper’s setting is determined by where the jumper is
placed on the pins. Use the following table to identify the
pin settings for 2-pin, 3-pin, and 4-pin jumpers. To identify
pin 1, look at the system board under the jumper. You will
see a triangle traced on the board at pin 1.
