Processor Graphics Registers
106 Datasheet, Volume 2 of 2
4.1 Vendor Identification (VID2)—Offset 0h
This register combined with the Device Identification register uniquely identifies any
PCI device.
Access Method
Default: 8086h
4.2 Device Identification (DID2)—Offset 2h
This register combined with the Vendor Identification register uniquely identifies any
PCI device. This is a 16 bit value assigned to the processor Graphics device.
Access Method
Default: 59XXh
Type: CFG
(Size: 16 bits)
Offset: [B:0, D:2, F:0] + 0h

DID_MSB: This is the upper part of a 16 bit value assigned to the Graphics device.
Reset value is written to 0x160 on the processor by hardware fuse distribution. Bits 5
and 4 are updated based on the GFX level by hardware.
