[rescue] Did i nuke my SS20?

[Mark M]

Check serial output, I had a similar thing happen with my blade150 ( I
know, very different arch, but still kinda similar), swapping nvrams(and a
backwards insertion!) put it into max diag, so post was ~10minutes of
display silence, I assumed the same.

For me, all was well, and I stopped trying ebay nvrams and just soldered a
battery (my blade150 board rev doesn't have the onboard 2032).

Good luck!
