Changing Jumper Settings

If you change your computer’s configuration, you may need to

change a jumper setting in the computer. A jumper is a small

electrical connector that controls one of the computer’s

functions.

A jumper’s setting is determined by where the jumper is placed:

either between pin 1 and pin 2 (position 1-2) or between pin 2

and pin 3 (position 2-3), as shown below:

position 1-2

position 2-3

Jumper J5 on the main system board is different from the other

jumpers in the Equity 386SX. The pin positions for jumper JS

are shown below:

position 1-2 position 2-3

c@?

cJ?$?

The jumpers you may need to change are on the main system

board. There is an additional jumper on the SIMM card that

you may want to check if your dealer has installed SIMMs for

you. The following tables list the jumper settings and their

functions.
