pnpbios provides support for finding and attaching
devices by extracting information from the PnP BIOS of a machine.

pnpbios driver appeared in NetBSD
1.5.
pnpbios bus provides a different way to attach
devices than the real buses (e.g.,
isa(4)). The reason to use
pnpbios instead of the real bus is that some machines
have weird routings of, e.g., interrupts. The exact information about these
things can be found in the BIOS, which is why the
pnpbios bus has a better chance of succeeding with
getting it right.
Many older BIOS implementations do not support PnP, and some newer ones do not follow the standards.
