@mei @mykoryza @hswaw we have v1 mobo that only supports Zen 1 EPYCs. v2 supports Zen 2. We can download v2 firmware and we know it does not fit in 16MB. We also know v2 has 32MB Flash chip. We suspect that soldering a larger chip for the newer firmware to fit might be enough for Zen2 to work. But it’s risky to YOLO it. Being able to carefully compare the two revisions side by side could tell us if there are other significant differences.
