Gang,
I have been unsuccessful in building a working MP bootcd for a while now. I conferred with Hartmut about some of the details, but still cannot get it working.
This is what I tried:
- Set MP=1 in config.xml
- Hacked the hal xml files to make halmp.dll hal.dll on the bootcd, per Harmut

- make bootcd, as normal
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 resulting bootcd fails to boot under "qemu -smp 2" with the following trace:

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.
