You should not use that card in the Soundblaster pro mode. This gives
you only limited 8 bit sound. Better use the WSS driver with that card.

a. That's right. b. You have no reason at all to boot to Dos, isapnp
and the sound driver will overwrite the dos settings anyway.
However, what you really need to do depends on the kernel
that you use and also on your bios.
The free driver for the OPTi 82C931 is using the card in it's non-PnP
mode.
With older sound driver:
(Linux 2.0.34 and older. I'm not sure about 2.0.35).
There are several web sits that tell you how to set-up this card.
You need to set isapnp in a way that will disable PnP for the card.
Then, there is a user-mode program that patches some registers
and then you can use the card as if it were a 82C931.
With newer sound driver:
(recent development kernels, possibly 3.0.35 or patches available
from Alan Cox). Everything needed for configuration in the mad16 driver.
(actual sound processing is in the ad1848 driver).
Modularized sound driver is recommended. You may need to run isapnp
but later when the sound driver is loaded it reinitializes the card
with its own settings. Isapnp is needed to resolve the card only if
you do not have a PnP bios.
Write to me directly if you still have problems. Please give an exact
description of your hardware, which system you use, do you have any
experience with patching/configuring/compiling the Linux kernel?
