The 7I43 connects this to +5V. Most MB headers have this pin open or
its a key (pin missing). If its grounded on the MB there will be trouble
I ran in to the same problem. Motherboard died so replaced with a spare (GA-P35-DS3P) which only has internal parallel header. Made a 26 to 26 pin cable and could not get LinuxCNC to start. Saw this post and cut pin 26 cable and now works.
