Page 41 highlights

Interrupt and DMA Assignments Most IRQ assignments are dynamic because of Plug-and-Play and PCI configuration. However, some are fixed based on legacy requirements, as shown in the table below. Because the SurePOS 500-XX3 design will make use of the APIC interrupt controller in the ICH4, there will be 20 interrupts instead of 16 as we had in the previous designs. The legacy ISA interrupts are the same from 0 - 15, and interrupts 16-19 correspond to the PCI interrupts INTA, INTB, INTC, and INTD. Thus PCI devices no longer need to take an ISA interrupt with the APIC design.
