INTR_LN—Interrupt Line Register (Modem—D31:F6)
Address Offset:
Default Value:
Lockable:
This register indicates which PCI interrupt line is used for the AC ’97 module interrupt.
INT_PIN—Interrupt Pin (Modem—D31:F6)
Address Offset:
Default Value:
Lockable:
This register indicates which PCI interrupt pin is used for the AC ’97 modem interrupt. The AC ’97
interrupt is internally OR’d to the interrupt controller with the PIRQB# signal.

Interrupt Line (INT_LN) — R/W. This data is not used by the ICH4. It is used to communicate to
software the interrupt line that the interrupt pin is connected to.
Next Capability (NEXT) — RO. This field indicates that this is the last item in the list.
Capability ID (CAP) — RO. This field indicates that this pointer is a message signaled interrupt
capability.
Reserved
Interrupt Pin (INT_PN) — RO. Hardwired to 010b to select PIRQB#.
