Quick answers before I go tinker -
I have not done anything with the firmware, so I will work on that in a
sec. Sounds like a simple copy paste thing, correct?
I have no USB devices besides the mouse plugged in, and no firewire at all.
No specail boot parameters as far as I know. How would I check?
I will post output of the command in a sec.
