Controller Problems

You see a controller error for the hard disk drive controller,
the video controller, or the I/O port controllers when you
start your system.
The indicated controller on your system board may be faulty.
If you have an option card with a controller that will work with
your device, you can install it and change the jumper settings
on the system board to disable the built-in controller. You can
then continue to use your system until it is convenient for you
to have it serviced.

Mouse Problems

Your mouse isn't working properly or you see an auxiliary
device error message.
Make sure the mouse cable is securely connected to one of the
serial ports. Also make sure you installed the mouse driver
correctly and selected the right settings for the serial ports in
the SETUP program. See the documentation that came with
your mouse and Chapter 1 for instructions.
