Controller Problems
You see a controller error for the drive controllers or the I/O
port controllers when you start your system.
If the error message refers to your PCI IDE controller, make
sure jumper JP25 is set to off; see “Changing the Jumper
Settings” in Chapter 4 for more information.
If the error message refers to your diskette drive controller,
make sure the controller is enabled in SETUP; see “Configuring
integrated peripherals” in Chapter 2 for more information.
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.

You may have installed the external cache chips incorrectly.
They may be the wrong type, or they may not be inserted all

access speed of 15ns or 20ns.
Also, you may not have changed the SETUP program or the
jumpers to recognize the new cache. Make sure you have set
