Apparently, the M2-ATX may have timing issues due to the pic code sending the pulse to the motherboard before the rails are fully powered. This user claims that a reprogramming of the pic code fixes this issue:

Can someone give a bit more information on this issue? If I were to get a pic programmer, which part of the code needs changing?
