Support for Zen, Zen+ and Zen 2 is a bit confusing to me. Take the ASRock Taichi x470 and x570 boards for example.
Taichi X470 support
The CPU support list does list Zen, Zen+ and Zen 2.
The latest bios offers AMD AGESA Combo-AM4 1.0.0.3 ABB support but with this disclaimer:
"ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system."
No bios support for AMD AGESA Combo-AM4 1.0.0.3 ABBA yet
Taichi X570 support
The CPU support list only includes Zen+ and Zen2
The latest bios supports AMD AGESA Combo-AM4 1.0.0.3 ABBA
My question is will B450 and X470 boards offer AGESA 1.0.0.3 ABBA and further updates in the future?
