AMD To Support Zen 3 and Ryzen 4000 CPUs On B450 and X470 Motherboards

New submitter FallOutBoyTonto shares a reprot from AnandTech: AMD today is reversing its decision to limit the BIOSes on the 400-series chipsets. To cut a long story short, the TL;DR mantra from AMD is: "We've heard our audience, and we understand the concerns. We are going to work out a way to support Zen 3 on our 400-series chipsets between now and launch -- we're still working out the what and the how, but we will update you closer to Zen 3 launch. [...]
1. We will develop and enable our motherboard partners with the code to support 'Zen 3'-based processors in select beta BIOSes for AMD B450 and X470 motherboards.
2. These optional BIOS updates will disable support for many existing AMD Ryzen Desktop Processor models to make the necessary ROM space available.
3. The select beta BIOSes will enable a one-way upgrade path for AMD Ryzen Processors with 'Zen 3,' coming later this year. Flashing back to an older BIOS version will not be supported.
4. To reduce the potential for confusion, our intent is to offer BIOS download only to verified customers of 400 Series motherboards who have purchased a new desktop processor with 'Zen 3' inside. This will help us ensure that customers have a bootable processor on-hand after the BIOS flash, minimizing the risk a user could get caught in a no-boot situation.
5. Timing and availability of the BIOS updates will vary and may not immediately coincide with the availability of the first 'Zen 3'-based processors.
6. This is the final pathway AMD can enable for 400 Series motherboards to add new CPU support. CPU releases beyond 'Zen 3' will require a newer motherboard.
7. AMD continues to recommend that customers choose an AMD 500 Series motherboard for the best performance and features with our new CPUs."
