i had linux installed but to get rid of it i attempted a full hdd reformat. (from the ps3 front end, of course)
3 hours later reformat was complete.
to make sure linux was gone, i decided to try to restart in other os mode.
to my surprise, the initial linux loading screen appeared (2 penguins) but then it stopped and failed to load.
i switched off the ps3 and when i started again only a black screen appeared.
Tried this a few times with diff av cables, no joy.
Seems dead because the controller wont sync with the machine either.
not too bothered, il just bring it back to GAME. Glad i didnt get a n import now!
