Dude ... I've just reviewed your last (and only) three posts here on the forum, and to be quite honest, something just isn't adding up. In fact, a question has drifted through my mind about exactly who's machine/HDD you are working on, and how and by whom fedora 12 got installed.
I recommend Google. I also recommend installing F16.
In the meantime, and until that nagging little question goes away, folks are free to respond via PM as they wish, but for now ...
... thread closed.
EDIT: Please feel free to PM me with details and further explanations.
