-Abstract:\r
-  Load File protocol as defined in the EFI 1.0 specification.\r
-\r
-  Load file protocol exists to supports the addition of new boot devices,\r
-  and to support booting from devices that do not map well to file system.\r
-  Network boot is done via a LoadFile protocol.\r
-\r
-  EFI 1.0 can boot from any device that produces a LoadFile protocol.\r
