Did you try the suggested -rc options with pnpdump? Those options will
do most of the work for you.

Please try the -rc options. I still am unable to make a good isapnp.conf
on my own, but the options will automatically create a working config
file for you.

You may need a newer isapnptools. I'm not sure if 1.21 supports
the -rc options.

Nothing. It just tells isapnp to give an error if there is an IRQ, IO,
DMA or memory conflict.

No. This is isapnptools-specific.

No. It is merely a comment. isapnp commands look like LISP code,
with all of those parentheses.

This line should be uncommented.

That's a command. Uncomment.

Ditto.

Yup.

Not strictly necessary, but a good idea, anyway.

Yes and no, respectively.

This is another set of IRQ, IO and DMA addresses. You're supposed to
pick one set. So you can leave these commented.

Doesn't matter, as long as isapnp thinks that there is no
conflict.

Just choose one address. isapnp will override any other settings if
it is a true PnP card.

Leave it alone if you don't want it at this address.

I think this is AWE. Better leave it in.

So AWE does use 0x620 as the address!

Just leave it commented out. You need the game port for MPU, by
the way. The game port is where MPU output goes.

Leave it in. It may be necessary.

Please try the -rc options to pnpdump, and without change /etc/isapnp.conf,
run isapnp immediately afterward. It should just work.
