Hi,
A while back I seem to recall that if you ran on an SMP system, that you
would end up with essentially 32 irqs. That doesn't seem to happen any
more. This particular motherboard (Supermicro P6DNE) is configured with
PNP OS set to yes. That is the only way I can get this box up and
running. Otherwise, it assigns every PCI board irq 11, and a that
point, no interupts are comming through.
Thanks,
Lars
