+Module Name:
+
+  Efi2WinNT.h
+
+Abstract:
+
+  Tiano mechanism to create WIN32 EFI code.
+
+  Only used for NT emulation environment. This file replaces the Tiano.h
+  when you need to access Win32 stuff in EFI.
+
+  Don't access Win32 APIs directly allways go WinNtThunk protocol.
+
+  In most envirnments gWinNt is a pointer to a EFI_WIN_NT_THUNK_PROTOCOL.
