The following BIOS listed on the Latest BIOS Update page is not published yet, only the beta 3.88 ... I feel like this might be accidental. The listing below from: https://www.asrock.com/support/index.us.asp?cat=BIOS B450M Pro4 3.90 12/16/2019 Update AMD AGESA Combo-AM4 1.0.0.4 Patch B *ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system. *Before updating this BIOS, please also read the description in previous BIOS version. |

 And now it has returned, just successfully flashed onto board with Ryzen 3600! I can confirm it eliminated the PSP initialization bug that caused the CCP to get disabled in Linux. Thanks ASRock! |
