Timing problems on a Risc PC motherboard
|
|
|
Some motherboards, especially older ones, seem to suffer from
timing problems in combination with some expansion cards, such
as 486 and 586 PC cards. Most of these problems can be cured
by removing a capacitor from the motherboard as it appears to
be unnecessary. In fact later versions of this motherboard
(such as the ones produced by Castle)
don't have this capacitor on at all.
However, some cases in the past have revealed that it is sometimes
better to have C32 present, even if it wasn't there before.
Unfortunately we cannot gove any guidelines as to the neccessity
of C32, so you will have to experiment.

The capacitor is in the centre front of the StrongARM connector
on the motherboard. It is called C32 but is not
marked as such. The drawing below is supplied to locate the
capacitor.
Removing or placing the capacitor involves some SMD soldering experience.
You should not do this yourself,
unless you know exactly what you are doing.
If in doubt, ask your local dealer to
do it for you (there may be some charge for it).
Note from one of our customers
When experimenting with C32 it may be wise to replace it with
a variable capacitor of 80pF so that you can find the best
value for your situation.
