All MB, no complete systems. Some are on the list (e.g. the ASRock Rack items), and some are not. But it strokes me as odd that 4/4 server boards have been epic fails when probably 8 or the last 9 unrated consumer boards I have tried have been 100% fine. Only one recent SOC Atom board was an exception.
They always seem to have the same odd video problems, and they all use that ASpeed server chipset for IPMI and video.
I was hoping the very odd symptom of no video at all for 5 minutes, right after the progress bar, and then suddenly video....100% repeatable...was a hint to someone of the issue. Very odd!
