Hi all,
I've got the CD interface on my LaserWave Nucleus to work properly
under Plan 9. The patch to devsbcd.c follows - it works for me, but I
haven't thought about doing it cleanly to coexist with a real SB CD
interface, so it shouldn't be applied unless you're trying to get
something like a LaserWave, LaserMate, or some other CD-only card
working. However, adding an INFO port as distinct from the DATA port
seems like a good general change.

i'm thinking of how to make this a general change to co-exist with the
sb16. what type of cdrom do you have?

It's branded as a LaserMate, but I think it's just a Panasonic CR-56x.
My patch isn't very reliable - it was enough to load the distribution, but
not for any serious use. It works so long as the CD is kept spinning, but
I think it shuts down after a couple of mins of idleness, and the driver
doesn't start it again. I think that would be a generic problem rather
than specific to my setup.
