>Description:
4.2-STABLE does not recognize PCNet-ISA+ cards I have. The problem is
present for long now, since 4-current days. The problem appeared after
PNPBIOS hit the 4-current tree, as I recall. Accordingly to
options.i386 file, the PNPBIOS is supposed to be optional, but it's
not because certain header is hard-coded into /sys/i386/i386/bios.c
file. However, I don't know the reasoning and this can be even normal,
but then option PNPBIOS does not make sense.
>How-To-Repeat:
Take an older, ISA-bus only 486-class machine which does not have PnP
BIOS. Configure PCNet-ISA+ card as non-PnP, assign I/O, IRQ and DRQ.
Boot appropriately configured kernel.
>Fix:
Not known.
For workaround some mods are required:
Remove following two lines from /sys/conf/files
isa/pnp.c optional isa
isa/pnpparse.c optional isa
Remove following hardcoded #include from /sys/i386/i386/bios.c
#include "opt_pnp.h"
