I have 2 5830's that I'm trying to overclock on a linux box, but as far as I can see the only way to do it is in windows.  I don't currently have a windows 7 license to use for my mining rig (but I have one on my laptop).  Anyone know a good way for me to get access to windows for an hour or two to unlock the card?  Is there a trial account or flash drive method to do this?
