According to the manual page 50 diagram 1-36 qcodes FB-FF are reserved for future AMI error codes so there is no clear definition of what it means. Code 55 is for the memory. My first board, which initially would boot, started halting on qcode 60. I immediately took it out and returned it to the retailer and exchanged it for another board which I am using now. Sometimes things happen so don't fret and go swap it for another board.
