+  Defines a Tag GUID used to mark a UEFI legacy BIOS thunk driver based\r
+  on legacy BIOS services and legacy option ROM. This Tag GUID must be installed on \r
+  the ImageHandle of any module that follows the EFI Driver Model and uses \r
+  the Int86() or FarCall() services of the Legacy Bios Protocol to produce\r
+  a standard UEFI I/O Protocol.\r
