Noobie here with a resurrected n800

Just succeeded - I got it working

One tip, when you press the power then eject key, hold the eject key and look for the message 'connected to USB' on the screen of the n800, if you don't see this then you almost certainly need to power off and try again.

I have 2 AT90USBKEY2's due to arrive Wednesday but I just couldn't wait that long to get in on the action.

Using the backup manager now to backup a few disks then I'm going to try the same technique on my other system which still has 3.15
