If you guys have 40 minutes to kill and want something that's kind of interesting and tech heavy to watch, GN did a pretty big deep dive on the BIOS issues surrounding compatibility between old motherboards and Zen 3.
Part of the problem seems to be that Zen and Zen+ cpus can't address more than 16mb of ROM in the BIOS. So if a BIOS has 32MB ROM and they decide to use that entirely to support the upcoming Zen 3, it would break a lot of Zen and Zen+ cpu compatibility. He does mention that you can technically partition the BIOS into two 16MB ROM sizes but that has it's own set of problems. Also a lot of the flashy UI and "features" of today's fancy BIOS also takes up a good amount of space.
It feels like BIOS flashback feature on motherboards should be mandatory going forward since that would have solved a lot of issues imo. There is one shining light at the end of the tunnel however cause Lisa Sue herself said in a vague email that they are working on a possible solution.
I sure hope with AM5, they don't completely drop long term socket support due to this.
