IRQ0, 1, 2, 8 and 13 must not be used for PCI interrupts (external inputs PIRQ [A…H]#, which
are only reserved for future usage) routing. If an interrupt is used for PCI IRQ [A:H], SCI or TCO
it must not be used for ISA (legacy)-style interrupts (via SERIRQ). In PIC Mode (8259.mode), PCI
interrupts are mapped to IRQ3-7,9-12, 14 or 15. If IRQ11 is used for Timer 2, software must
ensure IRQ11 is not shared with any other devices to guarantee the proper operation of Timer
2. The chipset does not prevent the sharing of IRQ11. Interrupts can individually be
programmed to be edge or level, except for IRQ0, IRQ2, IRQ8#, and IRQ13.
