This is because neither can rely on hardware in a market where the ability to interoperate with the Win95 PCI enumerator is the only real criteria for widespread distribution. > not necessarily match probe order, but it may be better to sit down with > one of the PnP books and attempt to make FreeBSD's attach order match, as > closely as possible, to what the PnP spec suggests for BIOSes. It would be much easier just to call the BIOS PCI entrypoint (which is obtained in -current but not used), however Stefan will tell you all sorts of horror stories about nonconforming PCI BIOSsen. Unfortunately, unless you can second-guess the BIOS you can't guarantee that you'll pick the same ordering that it does. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
