what size firewire pin cable do i need?

samhradh

hi all
first and foremost i am not a computer wizz at all so i hope this makes sense
basically i have 2 mac laptops- 1. macbook and 2.i book g4, which never gave any trouble until today.
the macbook will not start up when i turn it on- just shows flashing apple on screen. i tried a few things like holding down x,shift button after pressing power button and calling apple but no solution.
helpful lady in apple explained that i need to get firewire cable and hook up macbook(laptop with problem) to working laptop(ibook) and that basically the ibook will make the macbook all better
i have been trying buy firewire cable on line but it shows all these sizes like 4 pin to 6 pin etc,.
how do i find out what pin firewire cable i need?
any help would be great as i have college essay in and all my stuff on macbook:(

Look at this web page: http://en.wikipedia.org/wiki/IEEE_1394_interface

It shows pictures of the 4-wire and 6-wire connectors. They are distinctive, look at the sockets on your Macs and you will know which one to get.
