Hi Tomi, Thanks a lot! I was sure there would be some kind of procedure. My only problem now is that I have no root login and no other X1 to trade disk with :-( I was sort of hoping there would be a reset-jumper for this, but I guess I'm not that lucky. I'll try to see what I can come up with based on what this document outlines. Again, thanks a lot!
