When I try to boot using "failsafe" from my Knoppix 3.4 cd, I get an endless
stream of error messages of the form

isapnp: unexpected or unknown tag type X for logical device N (device 1), ignored

where N increases by 1 each time and X cycles among 0xa, 0xae and 0xff.

If I don't use failsafe the screen just goes blank until I press the reset button.

The machine is a celeron 400 system with an Abit BH6 motherboard and a soundblaster 16 sound card. I'm pretty sure the cd itself is ok because it boots Knoppix with no problems on a newer Athlon machine.

I can't see anything in the cheatcodes that is supposed to disable pnp detection. Is there any way of doing it? And if I can disable autodetection, is there a way of feeding Knoppix the correct information about my hardware?

Thanks.

Do you have isa-cards?

Yes, sorry, I should have made it clear that the soundblaster card is an isa card.

If I type "knoppix noisapnp pnpbios=off" at the boot prompt, knoppix boots.
It might be helpful to add a mention of noisapnp to the cheatcode
documentation in case someone else has the same problem in the future.

Once knoppix is running, I can successfully run
isapnp isapnp.conf
where the isapnp.conf file has been copied over from a redhat6 system that
runs on the same machine. That would seem to indicate that the isapnp built
into the kernel reads the device differently from the standalone isapnp program.
