Integrated Graphics Device (D2:F0) (Intel® 82945G/82945GC/ 82945GZ GMCH Only) 7.1.17 CAPPOINT—Capabilities Pointer (D2:F0) PCI Device: 2 Address Offset: 34h Default Value: 90h Access: RO Size: 8 bits Bit Access & Default 7:0 RO 90h 7.1.18 INTRLINE—Interrupt Line (D2:F0) PCI Device: 2 Address Offset: 3Ch Default Value: 01h Access: R/W Size: 8 bits Bit Access & Default 7:0 R/W 01h 7.1.19 INTRPIN—Interrupt Pin (D2:F0) PCI Device: 2 Address Offset: 3Dh Default Value: 01h Access: RO Size: 8 bits Bit Access & Default 7:0 RO 01h Description Capabilities Pointer Value: This field contains an offset into the function’s PCI configuration space for the first item in the New Capabilities Linked List, the MSI Capabilities ID registers at address 90h, or the Power Management Capabilities ID registers at address D0h. Description Interrupt Connection: This field is used to communicate interrupt line routing information. POST software writes the routing information into this register as it initializes and configures the system. The value in this register indicates which input of the system interrupt controller that is connected to the device’s interrupt pin. Description Interrupt Pin: As a device that only has interrupts associated with a single function, the IGD specifies INTA# as its interrupt pin. 01h = INTA#. 184 Intel ® 82945G/82945GZ/82945GC GMCH and 82945P/82945PL MCH Datasheet
