3 | Load File protocol provides capability to load and unload EFI image into \r |
4 | memory and execute it.\r | |
d8a43975 | 5 | \r |
6 | Load file protocol exists to supports the addition of new boot devices,\r | |
7 | and to support booting from devices that do not map well to file system.\r | |
8 | Network boot is done via a LoadFile protocol.\r | |
9 | \r | |
8a7d75b0 | 10 | UEFI 2.0 can boot from any device that produces a LoadFile protocol.\r |
