Changing the Jumper Settings
If you change your computer’s configuration or need to alter the
way it operates, you may need to change a jumper setting inside
the computer.
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 control certain features
by changing the standard settings as follows:
❏ Enable or disable the built-in mouse connector
❏
Enable or disable a mouse installed on an option card
❏ Set your monitor type to monochrome or color
❏ Change the amount of your base memory
❏ Enable or disable the power-on password function
❏ Enable or disable the built-in VGA display adapter
❏ Change the operation of the input \output ready signal.
If you add more memory to your computer by installing memory
modules, you must set a group of jumpers to indicate the amount
of memory you now have.
If you need to change any jumper settings, follow the
instructions below.
