SID—Subsystem Identification Register (Modem—D30:F3)
Address Offset:
Default Value:
Lockable:
The SID register, in combination with the Subsystem Vendor ID register make it possible for the
operating environment to distinguish one audio subsystem from another. This register is
implemented as write-once register. Once a value is written to it, the value can be read back. Any
subsequent writes will have no effect.
This register is not affected by the D3
CAP_PTR—Capabilities Pointer Register (Modem—D30:F3)
Address Offset:
Default Value:
Lockable:
This register indicates the offset for the capability pointer.
INT_LN—Interrupt Line Register (Modem—D30:F3)
Address Offset:
Default Value:
Lockable:
This register indicates which PCI interrupt line is used for the AC ’97 module interrupt.

Capabilities Pointer (CAP_PTR) — RO. This field indicates that the first capability pointer offset is
offset 50h
Interrupt Line (INT_LN) — R/W. This data is not used by the Intel
to software the interrupt line that the interrupt pin is connected to.
Subsystem ID — R/WO.
