ftp://ftp.opti.com/pub/chipsets/sound/ has a fair bit of stuff.
I think the 933 and 935 are still "proprietary", so you can't get them
w/o an OEM password.

The problem is that the regions it maps are not correct for a WSS
card. It maps 220/16, 534/4, 380/12, and e0c/4. 220/16 is the
standard SB area, and a WSS is 530/8, not 534/4 (the WSS config
is at 530/4, and the codec is at 534/4).

That's all I can figure out, or that the PnP mappings won't correctly
support a WSS card. There is some cryptic stuff in the user manual
(which I had to get from the web :-) about it "switching to windows
mode when Windows is launched," but I'm not sure what they mean.

Also, there's a cryptic mention of OPL5 support needing
388-38f, which isn't in the above mappings either. :-)

I'd really apreciate suggestions, then, on what to do when the default
mappings don't support the functionality I want to support. :-)

Also, does anyone have pointers on where to find info on programming
the OPL chips (the FM synthesizers)? On the web'd be spiffy.

Take care,
