		IN EFI_DEVICE_PATH_PROTOCOL *	FilePath,
		IN BOOLEAN	BootPolicy,
		IN OUT UINTN *	BufferSize,
		IN VOID *Buffer	OPTIONAL
	)

Causes the driver to load a specified file.

Parameters

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.

Return values

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 canceled.
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.
