Register Description3.7.16 CAPPOINT—Capabilities Pointer Register (Device 2)Address Offset:Default Value:Access:Size:34hD0hRO8 bitsBit7:0DescriptionCapabilities Pointer Value—RO. This field contains an offset into the function’s PCI configurationspace for the first item in the New Capabilities Linked List, the ACPI registers at address D0h.3.7.17 INTRLINE—Interrupt Line Register (Device 2)Address Offset:Default Value:Access:Size:3Ch00hR/W8 bitsBit7:0DescriptionInterrupt Connection—R/W. This field is used to communicate interrupt line routing information.POST software writes the routing information into this register as it initializes and configures thesystem. The value in this register indicates which input of the system interrupt controller that thedevice’s interrupt pin is connected to.This register is needed for Plug-N-Play software.Settings of this register field has no effect on GMCH operation as there is no hardware functionalityassociated with this register, other than the hardware implementation of the R/W register itself.3.7.18 INTRPIN—Interrupt Pin Register (Device 2)Address Offset:Default Value:Access:Size:3Dh01hRO8 bitsBit7:0DescriptionInterrupt Pin—RO. As a single function device, the IGD specifies INTA# as its interrupt pin.01h = INTA#.Intel ® 82865G/82865GV GMCH Datasheet 109
