What happens when you use the FULL ACPI support? I suspect that you really do want the interpreter, in order to evaluate _PRTs properly. ISTR that the reason you are thinking that ACPI only is programming some of the ioapic entries is because whatever is printing them is looking at the mp_irqs array. Which is MPS specific. So ACPI doesn't bother filling it all in. :) Is that a bug? Should ACPI fill it in completely, or maybe not at all? Don't know. But it is strictly unnecessary. Regards -- Andy
