There are some new processors to be released soon, Ryzen 3 3100 and 3300X, likely they'll need a firmware update as all of the sudden a handful of X570 motherboards show a BIOS update, with firmware revision 188.8.131.52.
MSI seems to be the first to drop the new BIOS update AGESA 184.108.40.206. ComboAM4 220.127.116.11 is currently only available from MSI for the following models:
- B450M-A Pro MAX

- B450M Pro-M2 MAX
- B450M Mortar MAX
- B450-A Pro MAX
- B450 Tomahawk MAX
- B450 Gaming Plus MAX
An unofficial and thus beta test BIOS is available for the MEG X570 Ace and MEG X570 Godlike reports Hardwareluxx. From the looks of things, MSI testing its B450 mainboards before extending the update to other models. The changes list is minimal though:
- Updated AMD AGESA ComboAm4PI 18.104.22.168
- Fix HDMI audio lost issue when use AMD RX570 vga card.
