Just a note, the 16MB limitation has been regarded as a scapegoat excuse given at the time, since there are X570 boards that shipped with 16MB BIOS chips. My personal workstation is an ASRock B450 Pro4, which also has a 16MB BIOS chip, and has already had its Ryzen 5000 supporting beta BIOS released.Yea that's a shame about the 16MB BIOS ROM on the X470D4U
Now that does not mean that ASRR will enable Vermeer on their X470 series boards, but I personally hope they do, especially given that, unlike most 400 series desktop boards, the X470D4U series does not officially support the first-gen 1000 series Ryzen chips, so dropping support for them (if they needed room in the BIOS rom) would not pose a compatibility problem for them.
