Hi all.

Sorry if the answer to this question is obvious, but I don't know enough
about hardware to be certain of all the possibilities.

Could anybody tel me what kind of errors I would see if needed to define
REALLY_SLOW_IO to read write io ports ? Or beter yet, How do I find out
if my hardware is too slow ?

I'm writing a driver for a Bitbus card. I don't have problems accessing
the hardware yet. But then I have been using recent hardware. I would
like my driver to use older Bitbus cards, and also I would like this driver
to function on old 386 boxes that I have arround here.

Thanks,

Ernest.
