I believe there were security patches in L01 2.78 ( probably related to MeltDown / Spectre ), so wondering why it went away.  It seemed to work OK for maybe two years.   How does one search for these?

if there was a more recent one, but no longer available, it may be that there was another problem, and obviously they did not make another one!

Thank you for the link, i am amazed you were able to find that! 

Just as i thought, 2.78 provided a newer intel microcode, most likely with better instructions to protect against meltdown.

ENHANCEMENTS:

• Update to latest Intel microcode 0x28
• Due to security changes, after loading this BIOS, older versions cannot be
  installed.

Just a matter of habit...
I insist, it is not without risk, the information given must be correct, but not immune to a problem, in this case it could be difficult or even impossible to go back!
