+Abstract:
+
+ This file is part of the IGD OpRegion Implementation. The IGD OpRegion is
+ an interface between system BIOS, ASL code, and Graphics drivers.
+
+ Supporting Specifiction: IGD OpRegion/Software SCI SPEC
+
+ Note: Data structures defined in this protocol are packed not naturally
+ aligned.
+
+ GUID forms:
+ {CDC5DDDF-E79D-41ec-A9B0-6565490DB9D3}
