I can build a smp boot cd. The smp build runs on my smp machine (ASUS
P2B-DS motherboard with 2xPIII 500MHz). I've also boot the smp build on
my amd64. I've update my pc with a amd64x2 cpu. Since the update, the
smp build won't boot. Ros hangs before I can see any debug messages.

The ipi interrupt isn't sent to the second cpu. I've looked to the qemu
apic code. The 'fixed delivery mode' isn't implemented in
apic_bus_deliver (hw\apic.c). This means,  a smp version of windows,
linux or ReactOS will not run with qemu.
