+
+Abstract:
+
+  Load File protocol as defined in the EFI 1.0 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.
+
+  EFI 1.0 can boot from any device that produces a LoadFile protocol.

+/*++
+
+  Routine Description:
+    Causes the driver to load a specified file.
+
+  Arguments:
+    This     - Protocol instance pointer.
+    FilePath - The device specific path of the file to load.
+    BootPolicy - If TRUE, indicates that the request originates from the 
+                 boot manager is attempting to load FilePath as a boot
+                 selection. If FALSE, then FilePath must match as exact file
+                 to be loaded.
+    BufferSize - On input the size of Buffer in bytes. On output with a return
+                  code of EFI_SUCCESS, the amount of data transferred to 
+                  Buffer. On output with a return code of EFI_BUFFER_TOO_SMALL,
+                  the size of Buffer required to retrieve the requested file.
+    Buffer     - The memory buffer to transfer the file to. IF Buffer is NULL,
+                  then no the size of the requested file is returned in 
+                  BufferSize.
+
+  Returns:
+    EFI_SUCCESS     - The file was loaded.
+    EFI_UNSUPPORTED - The device does not support the provided BootPolicy
+    EFI_INVALID_PARAMETER - FilePath is not a valid device path, or 
+                             BufferSize is NULL.
+    EFI_NO_MEDIA - No medium was present to load the file.
+    EFI_DEVICE_ERROR  - The file was not loaded due to a device error.
+    EFI_NO_RESPONSE - The remote system did not respond.
+    EFI_NOT_FOUND   - The file was not found
+    EFI_ABORTED - The file load process was manually cancelled.
