playmidi also works with sbpro and I was able to listen to midis from the 
web, and a few streaming mp3 files with mpg123 (see my posted scripts)

dma2=0 also worked for me just now.

Adding these last two may have made mplayer and timidity louder.  (???)
They were pretty faint before.  timidity -N 300 to make it 3 times louder,
or mplayer press forward slash a few times.

I had mistyped 540 instead of 530 - corrected it here.
(Typical io for microsoft sound system).

Works in Puppy Linux if you do NOT select cs423x in the first menu but
choose 'legacy' and then uncheck all but cs4232 and let it find 
parameters.  I have no idea what file it put this information into.

Lots of helpful ideas from Puppy.  There is an Opera adblock around.
Also Opera 10.5 and later dropped qt so maybe we can get it to work with 
BL2.  (If it can use SW11 or older glibc).  xftConfig needs to be fixed
so that Opera 9 will use the right fonts.

Next challenge.  Found in 166-200MHz laptops.  Not one of the legacy 
cards listed in Puppy, I don't think.  Works in Win95/98, of course.
