You definitely need APIC for SMP and the APIC is part of the iA32 spec so I'm sure you have one somewhere. At a quick guess, I suspect you haven't enabled the APIC in your BIOS - check for an option that allows you to select between PIC and APIC interrupt types. If that's not the problem, we need more information: Motherboard/BIOS type and at least the beginning of a verbose boot (down to about the pci0 probe). -- Peter Jeremy _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
