OK I am a total noob when it comes to Linux and it's variations. The unit I was given has a demo program that seems to be written in the root or perhaps on the persistent flash drive of the unit. Is there a key hold sequence other than the one that causes it to go to factory_reset? This does not help me out all it does is reload the demo program. I would love to be able to use this unit even if I have to replace the OS. So any assistance would be extremely helpful and appreciated.
