so how long should it take to install pin headers? 10 mins? well i got the iron out (20watt) and new desolder braid and for the life of me could not get all the holes to open up after a long time i had the pin headers in and soldered on the pins that required it. conected front daughter board, power supply in and nandx installed (two lights on) fired uo the jtag tool and get the message that it couldnt detect the device, quick read of forum says its my soldering. 2 hours later having checked every joint using close up blown up photos and multi meter still no joy. So i put the dam thing back together (boots and runs fine dash 6 something) and ill sell the damm thing, time to move onto box two and use qsb's this time
