+  Load File protocol as defined in the UEFI 2.0 specification.
+
+  Load file protocol exists to supports the addition of new boot devices, 
+  and to support booting from devices that do not map well to file system. 
+  Network boot is done via a LoadFile protocol.
+
+  UEFI 2.0 can boot from any device that produces a LoadFile protocol.
