Advanced Interrupt Controller
The I/O Controller incorporates the Advanced Pro-
grammable Interrupt Controller (APIC). While the
standard interrupt controller is intended for use in a
single-processor system, APIC can be used in either a
single-processor or multi-processor system.
APIC Interrupt Mapping
The I/O Controller supports a total of 40 interrupts.
Each interrupt is assigned a unique vector by software.
Table 25 identifies how each interrupt is routed into
the I/O APIC inputs.
