Extrenal Cache Problems
The amount of cache displayed by the power-on
diagnostics program is inconect.
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, 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 cache option to Enabled and set both the
System shadow and the Video shadow options to Enabled.
See Chapter 4 for instructions on changing the jumper settings
or information on installing external cache; see Chapter 2 for
instructions on using the SETUP program.
