Heck Trev, given that getting enough info out of some posters is like getting blood from a stone, don't complain when we actually get offered more than might strictly be necessary.I'm just not certain why you posted a pic when your second post gave the info required.
Context is everything. As an engineer, I have never used "NVM" but often "NVR".NVM = non-volatile memory, NVR = Network Video Recorder
You've damaged your reputation on that one
People often talk about "PIN number", but it doesn't mean they are right.nvram is the accepted short form for non volatile ram.
