|
.Sh CAVEATS
|
|
The
|
|
.Nm
|
|
bus provides a different way to attach devices than the real buses
|
|
(e.g.,
|
|
.Xr isa 4 ).
|
|
The reason to use
|
|
.Nm
|
|
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
|
|
.Nm
|
|
bus has a better chance of succeeding with getting it right.
|
|
.Pp
|
|
Many older BIOS implementations do not support PnP,
|
|
and some newer ones do not follow the standards.
