9 Most (all) Intel-MP compliant SMP boards have the so-called 'IO-APIC',
12 IO-APIC, interrupts from hardware will be delivered only to the

16 multiple IO-APICs. Multiple IO-APICs are used in high-end servers to

21 not boot Linux, then consult the linux-smp mailing list archives first.

43 In the unlikely case that your board does not create a working mp-table,
44 you can use the pirq= boot parameter to 'hand-construct' IRQ entries. This
