Quoted from EdHess:
The board is 2 months old from Fred swemmer. NVRAM is correct number.
I am new to this and read all I can here but have never seen HOW TO PING out traces. Problem just started a week or so ago. Haven’t emailed Fred yet. I will now.
PING OUT just means using a digital multi meter on the continuity setting and ensuring the traces from pin to pin have continuity.
Don't confuse new for good. Man made bound to fail.
