Ryzen Zen 2 Procs Incompatible With Some Older 300-Series due to BIOS limitation?
Many of you are waiting on the launch of ZEN2 aka Ryzen 3000 and have an X370 motherboard in the hope to upgrade to the new proc. That might be an issue, indications right now it probably might not work on older 300-series chipset motherboards such as X370.
Website Forbes has posted a response sent by motherboard manufacturer MSI towards a Reddit user, in that reply the company mentions that AMD's Zen 2 processors will not work on older 300-series chipset motherboards. The company claims that the new CPUs will only work with 400-series, such as B450 and X470 chipsets. Shortly thereafter we've seen news-posts that MSI would be doing this purely out of pure greed etc. Such wording seems to be incorrect.
Really, this raises the question if all motherboard manufacturers will face the same issue, or it this might be an individual motherboard manufacturer decision as to whether or now they support AMD's Zen 2 CPUs, which are due for release this summer. If MSI would not support it, chances are really high that there is incompatibility or a choice made at AMD to not support Ryzen 3000 on the 300 series.
Here's the likely and probable reason, earlier on it was indicated that a BIOS chip limitations could be a factor in whether your board can support 3000-series Ryzen processors or not, support for 3000-series chips may now come down to a question of something as simple as its 16MiByte flash storage on the (and all) 300 series. We know that the 400 series already anticipated this being able to store 32MiBytes. If that is the case, all motherboard more manufacturers will drop Ryzen 3000 support on X370, B350 and A320 as it is simply incompatible at least on the models with a 16MiByte flash storage. So that doesn't mean some models WILL actually support the new procs, if they can.
AMD is aware of this and is going to release an "AMD Ryzen Desktop 3000 ready" badge just to address this.
Update: After some rather gnarly accusations on the web MSI responded with the following:
"It has come to our attention that MSI customer support has regrettably misinformed an MSI customer with regards to potential support for next-gen AMD CPUs on the MSI X370 XPower Gaming Titanium motherboard. Through this statement we want to clarify the current situation," MSI said.
"At this point, we are still performing extensive testing on our existing lineup of 300- and 400-series AM4 motherboards to verify potential compatibility for the next-gen AMD Ryzen CPUs. To be clear: Our intention is to offer maximum compatibility for as many MSI products as possible. Towards the launch of the next-gen AMD CPUs, we will release a compatibility list of MSI AM4 motherboards," MSI added.

Well shit. Not cool. But still better than you know who.
At least AMD supported 1000 and 2000 chips on the 300 series chipset

If it truly is universal and not only a strong excuse for the mobo makers to boost their sales, I don't see it being hugely different from the scumbag move Intel did with Coffee Lake. In some sense it would be even worse because Intel never promises future compatibility and everybody more or less expects incompatibility from Intel these days. That's so even when Intel is being especially nasty like how they were by releasing the incompatible Coffee Lake so soon after the "we have perfect trust in" Kaby Lake. Intel doesn't even pretend to be customer friendly, but AMD did.
That's why I think it would be interesting if one manufacturer made some of their models compatible, creating a PR headache for the others.

For bios chip are we talking about the chip that contains the UEFI OS layer?
I believe they can cut on corners and made the code fit? Like a bios for people that wants to install it and will remove some functionality to save space. ( like checking from the internet if a new bios is available or this kind of things )

Honestly, even with AMD this had to happen at some point. I did not expect them to support their new releases on older mainboard forever.
What they should do is to offer a BIOS which you can flash under your own discretion (and under no warranty) that removes Ryzen 1000 compatability in favour of adding Ryzen 3000 BIOS. Would be a simple BIOS flash, if they offered such a version anyway.

Well, many older boards predating APU releases were not exactly best choices for them due to VRMs not being sufficient for iGPU.
One should consider it from technological perspective and then assess if it is reasonable or not.
Last thing company wants is to enable upgrade which will prove to cause issues.
Edit: On other hand, MSI lately makes boards which are not up to standard in their price range. And one is more often than not better off buying board from other manufacturer. Therefore there is chance that it may be just some or all MSI's boards.
