I got a used ASRock B450M-Pro4 board that was sold in a CyberpowerPC accordsing to the seller. Cyberpower, of course, have some cockamamie custom bios scheme that will not allow updates via the official ASRock bios releases. I made some progress by renaming the ASRock file using their stupid filename scheme and it at least was recognized by the Instant Flash system, but once initiated it returns "invalid file".

The current bios is is listed as P2.20, though I cannot find this documented anywhere, even on the defunct Cyberpower. It recognizes a Ryzen 5 3600, but that should be P3.10+, according to ASRock.

I would like to get this thing to P3.50, or at least understand what the P2.20 "Cyberpower" bios version entails...

Any thoughts?
