Load File protocol provides capability to load and unload EFI image into
|
|
memory and execute it.
|
|
|
|
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.
