Uh, no. :-) The same driver is used by all bus types, all that changes is the "probe glue" which the bus probes will call is that cards are identified on the right bus. Look at /sys/pci/bt9xx.c and you'll see that it's no more than a hundred lines (many of which are comments) long; it's just the PCI probe code and nothing else - the "meat" is bus independant. > From 2.2.1 GENERIC kernel we have: > controller bt0 at isa? port "IO_BT0" bio irq ? vector bt_isa_intr > > You want: > controller bt0 at pci? port "IO_BT0" bio irq ? vector bt_isa_intr And no, you most definitely do NOT want that. :-) -- - Jordan Hubbard FreeBSD core team / Walnut Creek CDROM.
