Serial Interrupt Request: This pin implements the serial interrupt
protocol.
PCI Interrupt Requests: In non-APIC mode the PIRQx# signals can
be routed to interrupts 3, 4, 5, 6, 7, 9, 10, 11, 12, 14 or 15 as
described in the Interrupt Steering section. Each PIRQx# line has a
separate Route Control register.
In APIC mode, these signals are connected to the internal I/O APIC in
the following fashion: PIRQA# is connected to IRQ16, PIRQB# to
IRQ17, PIRQC# to IRQ18, and PIRQD# to IRQ19. This frees the legacy
interrupts.
PCI Interrupt Requests: In non-APIC mode the PIRQx# signals can
be routed to interrupts 3, 4, 5, 6, 7, 9, 10, 11, 12, 14 or 15 as
described in the Interrupt Steering section. Each PIRQx# line has a
separate Route Control register.
In APIC mode, these signals are connected to the internal I/O APIC in
the following fashion: PIRQE# is connected to IRQ20, PIRQF# to
IRQ21, PIRQG# to IRQ22, and PIRQH# to IRQ23. This frees the legacy
interrupts. If not needed for interrupts, these signals can be used as
GPIO.
IDE Interrupt Request: This interrupt input is connected to the IDE
drive.
