Any mainboard device on a non-enumerable bus, including LPC, is _supposed_ to be reported in the ACPI tables -- precisely to avoid the need for drivers to engage in risky probing to find their hardware. That's no guarantee of course -- there are plenty of buggy BIOS around -- but it might be worth looking to see if this one got it right. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
