+Abstract:\r
+\r
+ This file is part of the IGD OpRegion Implementation. The IGD OpRegion is\r
+ an interface between system BIOS, ASL code, and Graphics drivers.\r
+\r
+ Supporting Specifiction: IGD OpRegion/Software SCI SPEC\r
+\r
+ Note: Data structures defined in this protocol are packed not naturally\r
+ aligned.\r
