-Module Name:

-

-  IgdOpRegion.c

-

-Abstract:

-

-  This is part of the implementation of an Intel Graphics drivers OpRegion /

-  Software SCI interface between system BIOS, ASL code, and Graphics drivers.

-  The code in this file will load the driver and initialize the interface

-

-  Supporting Specifiction: OpRegion / Software SCI SPEC 0.70

-

-  Acronyms:

-    IGD:        Internal Graphics Device

-    NVS:        ACPI Non Volatile Storage

-    OpRegion:   ACPI Operational Region

-    VBT:        Video BIOS Table (OEM customizable data)
