Interrupts

The interrupts can be routed through either the Programmable Interrupt Controller (PIC) or the
Advanced Programmable Interrupt Controller (APIC) portion of the ICH6-R component. The
APIC is supported in Windows* 2000 and Windows* XP operating systems and supports a total
of 24 interrupts.
