Unfortunately not having the APIC enabled in the BIOS also means that we cannot use PMCs, the APIC timer or the thermal monitor, even if the CPU implements these features. My too simple experiment attempting to enable the local APIC on an AMD K7 box didn't go very well; this would be entirely due to lack of clue on my part since Linux 2.4 seems to be able to turn on the APIC on the same hardware without issues. -- FreeBSD Volunteer, http://people.freebsd.org/~jkoshyReceived on Mon Nov 07 2005 - 12:45:06 UTC
