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 diskette drive or hard disk
drive controllers, make sure the jumpers for these devices are
set to enabled; see Chapter 4.
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.
External Cache Problems
The amount of external cache displayed by the power-on
diagnostics program is incorrect.
You may have installed the external cache chips incorrectly.
They may be the wrong type, or they may not be inserted all
the way. Also, make sure the tag chip you’ve installed has a
20ns access speed.
Also, you may not have changed the SETUP program or the
jumpers to recognize the new cache. Make sure you have set
t h e E x t e r n a l c a c h e a n d V i d e o s h a d o w o p t i o n s t o
Enabled. You can access these options from the Advanced
System Setup screen.
See Chapter 4 for instructions on changing the jumper settings
or for information on installing external cache; see Chapter 2
for instructions on using the SETUP program.
