In your case, add "ide2=noprobe" to the end of your kernel boot
line. However, Documentation/ide.txt seems to indicate that there
is no probing beyond the first two IDE interfaces, so I don't
think this will solve the problem.

I don't think I've ever seen one. Does anyone on this list know
how rare these are?

The c option to pnpdump tells pnpdump to choose appropriate settings
for you, so no editing is necessary. The r options resets the ISA PnP
hardware, and is not needed in all situations, but it does help.

GNU Parted can set the 'hidden' flag on DOS partitions. It can also
non-destructively resize partitions, unlike fdisk. It's basically
a better (and larger) fdisk.

I think this was answered several years ago on this list.

It works fine after the isapnp voodoo. ppp-on works with it, for the
first time.

If I try to specify dma16, I get a 16-bit DMA channel not available error.
MPlayer still works fine. I can't detect any quality problems from only
having 8-bit.

Is that for the AWE midi? Or is AWE midi on the main (e.g. 0x220) IO
address?

Probably.

setserial is unnecessary if serial support is in a module. Just
run isapnp first, then load the module and it will autodetect the
correct port.

No non-pnp setting here. This isn't really a Cirrus Logic modem; it's
really an Actiontec (I forget the model). It was originally an X2
modem (it would have said "ISA PnP 56K X2 Modem" above, instead of
Cirrus Logic) but I flash upgraded it.

I think anything which could have been on an ISA card eventually had
a PnP model. PCI eventually replaced everything, though.
