I picked up this Mac Portable and have seen a few loaded with different software etc but NEVER seen one like this. Can anyone shed some light on what these extensions might be, what or how that image of the portable has been added on boot or anything in general? This M5126 is also some kind of an early testing model. The board is much different than a stock M5126 board and has some internal Apple markings on it. It says "Aruba" is that some kind of code name?
