IEEE 1394 describes a high performance serial bus, which is also
known as FireWire(tm) or i.Link(tm) and is used for connecting all
sorts of devices (most notably digital video cameras) to your
computer.

If you have FireWire hardware and want to use it, say Y here. This
is the core support only, you will also need to select a driver for
your IEEE 1394 adapter.

To compile this driver as a module, say M here: the
module will be called ieee1394.
