Normally when replacing an 8" with a 5.25" HD, I would simply leave the
system configured for an 8" drive and make an adapter to connect the
5.25" drive to the 8" connector - I have not looked at this in detail, however
as long as you can set jumpers to connect the right signals to the right
places on the 5.25" connector it should work. Just make sure the signals
are the same ones that would go the the 8" Drive (no extra conditioning
