DO be sure you have the Firmware update. just in case, run the update utility. Thinking you have it won't help if you go to install OS X and it does not have the update. It will cause your computer to become a worthless paperweight. Also, remember that OS X has to be on the first 8GB of the harddrive. If it's not, it won't work. Since the board is based off the Gossamer, you will have to do this. It's the same with the gossamer.

again:

PLEASE PLEASE PLEASE Run the update utility first! Just to make sure. It will save from a lot of headaches down the road
