Changing the Jumper Settings

A jumper is a small electrical connector that controls one of the

computer’s functions. The jumper settings in your computer

are preset at the factory; however, you can alter the following

functions by changing the standard settings:

Change the microprocessor type

Enable or disable the built-in VGA display adapter

Enable or disable the built-in mouse port

Enable or disable a mouse or other pointing device on an

option card

Set the computer to use a color or monochrome adapter

Enable or disable the password function.

If you need to change any jumper settings, or if you want to

check the current settings, follow the instructions in this section.

The following tables list the jumper settings and their functions.

CPU type Jumper settings

CPU type

486SX/33

ODP486-33 or 487SX/33

You do not need to change jumpers J5 through J8 unless you

had to remove the existing microprocessor chip to install the

new one. See “Installing a New Processor Chip” on page 2-21

for more information.
