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