Re: OSS Sound Blaster sb_card.c rewrite (PnP, module options, etc) - Failed

[Paul Laufer <paul@laufernet.com>]

Shawn, Adam,

Yes. Failing here is certainly not the right thing to do. The
soundblaster only needs 4 bytes at 0x388, which brings it from 0x388
to 0x38b, not in conflict with the ttyS0 that starts at 0x3f8.

Furthermore the soundblaster has other configurations at "priority
acceptable" with and without the OPL (0x388-0x3f8, 4 bytes).

Here are examples for the two cards I have in my system now:

So you can see that the second card is configured correctly with OPL
IO address at 0x38c-0x38f, because the first card took 0x388-0x38b.

Adam, any insight as to what is causing Shawn's resource conflict or
why PNP isn't dropping to some priority where the OPL is not enabled?

Shawn, do you have "PNP Bios" enabled? If you turn it off does the
resource conflict go away (this happened to me before and then stopped
for reasons unknown to me).

Thanks,
Paul
