Dear Warner,
Many thanks for your explanation. The question is why PNPBIOS tries to
attach and assign resources to devices that have already been attached
(things like AT DMA controller, keyboard controller, math coprocessor,
printer port, etc.) Is it not smart enough to figure it out? And why
do I need this option to make my non-PnP ISA sound card work? Am I
right in assuming that some intrusive device probes (that break my sound
card) are avoided when PNPBIOS is defined?
Alex
P.S. Do you have the correct URL for PnP codes?
