are the CF cards absolutely identical? if not they may use different
controllers and one area of difference is how they handle the cable-
select line (which is how they determine whether they're master or
slave). you'll find more detail on this by searching the list archives.
try the combios settings (flash=primary/secondary) and you _may_ be
able to get the CF to be interchangeable, if not then try different
cards.
