MP 1,1-5,1 Healthy NVRAM normal behaviour on 4,1->5,1 machines

I have a different take, if anything is out of expected inside the Fsys store besides hardware descriptor blob/overrides swap with early-2009s, the BootROM warrants deep investigation and validation of hardwareIDs with ESN/MLB labels.

95% of the time I found other things wrong and while most are just backplane replacements gone wrong or botched third repairs, sometimes there are user tampering.

I agree, in every case it is a thing to look closer.

That is the intension to check it and write a note if it is in unusual order.
