CAPPTR: Capability Pointer Register
INTL: Interrupt Line Register
The Interrupt Line register is used to communicate interrupt line routing informaiton
between initialization code and the device driver. The Intel 5000 Series MCH does not
have a dedicated interrupt line and is not used.
INTP: Interrupt Pin Register
The INTP register identifies legacy interrupts for INTA, INTB, INTC and INTD as
determined by BIOS/firmware. These are emulated over the ESI port using the
Assert_Intx commands as appropriate.
Power Management Capability Structure
The DMA engine integrated device within the MCH incorporates power management
capability with D0 (working) and a pseudo D3 hot/cold states (sleep) that can be
controlled independently through software. From a software perspective, the D3 states
convey information to the power controller that the device is in the sleep mode though
the physical entity inside the chipset may be fully powered. During transition
to D3, it will ensure that all pending DMA Channels are completed in full.

CAPPTR: Capability Pointer
This register field points to the first capability. PM structure in the DMA Engine
device.
INTL: Interrupt Line
BIOS writes the interupt routing information to this register to indicate which input
of the interrupt controller this PCI-Exress Port is connected to. Not used in the Intel
5000 Series MCH since the PCI-Express port does not have an interrupt lines.
INTP: Interrupt Pin
This field defines the type of interrupt to generate for the PCI Express port.
