I guess in my mind I was saying that the drivers don't use any bios routines ... the booting is _not_ done by FreeBSD, so I was still right there, but the PnP assignment, perhaps the data from that (but not the routines) are used, is that a correct assumption? The point was, our device drivers don't make any use of bios routines. Is that right? You *are* a device driver author, so I'll assume you can answer that correctly. The Pnp stuff, I mean the assignment, is done before FreeBSD gets control, right? And there is never any call from FreeBSD to any bios code, right? Even remapped code, or any code originally copied from bios, right? > > cheers > luigi > -----------------------------+-------------------------------------- > Luigi Rizzo | Dip. di Ingegneria dell'Informazione > email: luigi@iet.unipi.it | Universita' di Pisa > tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) > fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ > _____________________________|______________________________________ > > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic (FreeBSD-current) (301) 220-2114 | and jaunt (NetBSD). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
