Is it a 9310, not a 9301? My sound card gives the same line (inclding the
OPTi Audio 16 stuff), except it's a 9310.

I've gotten the joystick port, and recently the IDE port, working, but
never got the sound card going. Actually if I weren't looking for ajob, it
shouldn't be too hard to get the 401 working.

The two problems I ran into were that the ad1848 expected an io range in
which it was the upper four of eight bytes. For this card, you only get
the exact 4 bytes needed. So I was going to change the ad1848 code to use
a subrange which was just its four bytes. That would be the 534/4 range in
this I/O card.

Also, I never got the MAD i/o code to work right with this card. :-(

I'm happy to help. If you get -current, you should get the IDE support.

Take care,
