+
+  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 - Should always be FALSE.
+    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       - BootPolicy is TRUE.
+    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.
+    EFI_BUFFER_TOO_SMALL  - The BufferSize is too small to read the current 
+                             directory entry. BufferSize has been updated with
+                             the size needed to complete the request.
