--- Comment #47 from Mark Millard <markmi@dsl-only.net> ---
(In reply to Mark Millard from comment #40)

Any attempt to run the request test is even more
blocked now:

The Ryzen system became unavailable early. An
attempted BIOS update for the MSI x370 Gaming
Pro Carbon from 7A32v15 to 7A32v17 left the PC
bricked with a debug LED that indicates "CPU not
detected or fail". It does not even begin to POST
as far as can be seen otherwise. There is no
publicly supported way to update the BIOS from
this status.

(I've been applying BIOS updates that report
improved memory compatibility or handling for
now. Other then that subject area I'd have been
happy to just leave the BIOS alone from the
beginning. The PC being an early-adopter PC I
figured on more BIOS updates applied than for
something well established.)
