How do I use isapnp?

[Ishaaq Chandy <kuru@lw1.vsnl.net.in>]

Hi,

I've been trying to get my PnP OPTi931 card (supposedly Soundblaster Pro
compatible) to work. Finally I managed to get it working by setting it
to IO 0x0220, DMA 1, IRQ 7 in DOS and then using Loadlin to load Linux.

However as the sound quality is awful and I prefer using LILO I am quite
unsatisfied with this compromise.

I heard that one can get the card working by using pnpdump, configuring
its output and lastly using isapnp on the configured output. I tried
this but pnpdump's output goes way above my head. Can someone help?

Here is pnpdump's output:

I did look at isapnp.conf but that made me even more confused.
I am using RedHat 5.0 and kernel 2.0.32.

Sorry for the length of the post but I did'nt know what to cut out. As
it is I'm not sure I have given all the info needed.

Thanks
