NetBSD/sys/arch/i386/pnpbios/wss_pnpbios.c
drochner 2298f7abf4 "pnpbios" pseudo-bus. Reads out device IDs and ressource usage from the
BIOS and attaches devices to it.
While it is potentially able to deal with all the motherboard ISA
devices, it is only used in hairy cases for now - laptop stuff in
particular.
