It should be use BIOS setup for PnP, if it can. I agree in principle, but let me think about how to implement that.

I feel uncomfortable about modifying that code without some indication from Nate, or our new chieftan Scott, that such a modification would be accepted. I really don't want to waste time on code that will never see the tree. I do think that setting up the pcic code to take a port at kernel config time is a reasonable thing to do. - ---------------------------------------------------------------------- Ted Faber faber@isi.edu USC/ISI Computer Scientist http://www.isi.edu/~faber (310) 822-1511 x190 PGP Key: http://www.isi.edu/~faber/pubkey.asc -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNwo9z4b4eisfQ5rpAQEjsQQAmbaKgbq1YYwoYkd1+PyOh7zb8MNfPP/P q0Dg9h6piuJWr8d46ALbS532lFgHfRsDJ9Jxknz6hp6DihwGBXHA2ug16u2AxJ8o R9/6P4qjxIAKW5edKk5Eue6lsz+UxxihiZX0dVe7778O6DeLy8+yW9kXHnXkL7mP NOkmEV7bzUk= =si9p -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
