+Abstract:
+
+  The EFI Legacy BIOS Thunk Protocol is used to abstract Thunk16 call.
+
+  Note: The names for EFI_IA32_REGISTER_SET elements were picked to follow 
+  well known naming conventions.
+
+  Thunk - A thunk is a transition from one processor mode to another. A Thunk
+          is a transition from native EFI mode to 16-bit mode. A reverse thunk
+          would be a transition from 16-bit mode to native EFI mode.
+
+
+  Note: Note: Note: Note: Note: Note: Note:
+
+  You most likely should not use this protocol! Find the EFI way to solve the
+  problem to make your code portable
