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