   3   Load File protocol.
   4
   5   Load file protocol exists to supports the addition of new boot devices,
   6   and to support booting from devices that do not map well to file system.
   7   Network boot is done via a LoadFile protocol.
   8
   9   UEFI 2.0 can boot from any device that produces a LoadFile protocol.
