Unfortunately not having the APIC enabled in the BIOS also
means that we cannot use

hi,
FreeBSD 6.0 always uses local APIC for the clock.
But on my Pentium 3, 850 MHz machine, it doesnt detect local APIC and
falls back to using the motherboard clock for the clock interrupts.
I figured this out by printing the value of
"using_lapic_timer" variable in the sys/i386/isa/clock.c fi
