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.

You do not need to change jumpers J5 through J8 unless you
had to remove the existing microprocessor chip to install the
