A couple of problems with Asrock X570 Taichi

Can anyone with X570 Taichi please confirm, if you are still getting this bug with 2.70?

Another confirmation, that it happens to Windows users too:

I forwarded this to Asrock. Not sure what kind of other proof they need to actually take a look at this obvious bug.

Releasing Betas is not common practice, this typically only happens when an
immediate stop gap solution is required for a more wide spread issue.

JZ works closely with ASRock and helps to test pre-release BIOS versions. He does
not however work for ASRock. Once he has tested a BIOS and found it to be safe he
is kind enough to share them on his website for anyone who wants/needs to test
them.

I can usually also get access to these early betas but without owning a shop
(like JZ) I don't have the inventory to test them all and make sure they are
safe. Generally I prefer to leave providing beta BIOS versions to Tech Support
(via support ticket) or through JZ who is extremely knowledgeable on BIOS
testing, programming and fault finding.

Early BIOS testing, outside of the manufacturer's in house testing, is
typically only done by SIs (system integrators). It is not standard practice to
release these to the general public, the risk of causing bad flashes or major
faults is just too high. What JZ uploads to his site has typically been tested
by him and found to be at least stable enough to allow you to POST and flash
back to a release version if you have problems.

Downloading and updating to Beta versions not provided on the ASRock website is
done at your own risk. JZ puts a lot of effort into making this safer but even
then, there is always the potential for issues on certain hardware combinations
that he has not or can not test. Fortunately, ASRock is very good with helping
users when a bad flash occurs (bricked BIOS/board). I have seen them help even
when a product is out of warranty on many occasions.

That page doesn't show any BIOSes for me by the way. Why did Asrock stop posting betas on their own support pages?

Nobody assumed that, it just was an info, that other boards obviously are also not perfect.

But a new bios for your board is on the way, and a beta for the X570 Taichi is available yet.
