+ 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.
