+    

+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
