2.6 Interrupts
The interrupts can be routed through either the Programmable Interrupt Controller (PIC) or the
Advanced Programmable Interrupt Controller (APIC) portion of the ICH5 component. The PIC is
supported in Windows 98 SE and Windows ME and uses the first 16 interrupts. The APIC is
supported in Windows 2000 and Windows XP and supports a total of 24 interrupts.
