FreeBSD contains code the configure PnP cards, but doesn't have the smarts on what parts of the system are free for the card to use... what happens if you have an unsupported arcnet card in the machine that you use in dos mode? how is FreeBSD suppose to know about that card and not use the same resources that the card uses... of course you will counter with, "but Win95 does this!", yes, they do, but they also happen to have all manufacturers writing drivers and detection routines for them so they can be pretty sure about what resources are free... Win95 will have the same problem FreeBSD will if you stick a card of your own make (i.e. NO win95 drivers) into a machine... FreeBSD just doesn't hide the problem... > Is there any particular reason (besides lack of interest or resources) for > no implementing this? well, the code that deals with the isa bus (and all busses for that matter) is actually going under a complete rewrite... once that is done we should be able to support autoconfiguration of PnP devices... -- John-Mark Gurney Modem Rev/FAX: +1 541 346 9237 Cu Networking P.O.
