pnpbios
provides support for finding and
attaching devices by extracting information from the PnP BIOS of a
machine.
NetBSD includes the following
pnpbios
drivers, sorted by driver name:
The pnpbios
driver appeared in
NetBSD 1.5.
The 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.
