Hi Charlie,
I've reinserted it a few time and also used a different JAT file which
I downloaded direct from the CB website. Still not getting any
recognition of this card. I've loaded other .bit files with no
problems at all, so I can't see why the JAT bit file would be a
problem. This is very frustrating indeed. As I mentioned, inserting
the demo card also gives me a card not recognized, but doing a reset
on the Apple then pulls up the list of files it contains, and I can
run them no problem. A reset while using the bitstream card does not
have this effect. I'll keep trying stuff, and see if I can't see some
sort of pattern to the problem.

Thanks again

Phil
