Controller Problems
You see a controller error for the drive controllers of 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.
External Cache Problems
The amount of 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
the External cache
option to
Enabled
and set both the
System shadow
and the
Video shadow
options to
Enabled. You can access these
options from the Memory
Cache
and Memory
Shadow
options on the Advanced System
Setup screen.
See Chapter 3 for instructions on changing the jumper settings
or information on installing external cache; see Chapter
1
for
instructions on using the SETUP program.
