Hi everyone,

Having a small issue with my origin 350. After I Start the system in the maintenance menu, its just lists the basics of the Operating system, ending in "all rights reserved" and just waits.
I may have been playing around with the serial port settings, would this most likely be the cause? if so what is the easiest way to fix this? 
I was probably going to attempt a system recovery, but I thought I'd put it to the experts first.

Cheers,
