Im having a fragging problem, too. frag with chip on, boots fine into ms dash with the chip off. Visually the lpc points look soldered correctly, I have resoldered them many times hoping to catch myself missing something.
I just realized something that may be a problem. I soldered all 11 pins to the lpc points on the underside of the board. I really dont think this should be an issue, since if those extra pins could cause the chip to not work, we would have been told to remove them before installing the headerpin cuz they'll probably end up touching the point just by being there.
Anyone know if this will cause an issue?
and a big thanks to McGeyser, your last post is full of very useful info.
