I think the IOMMU may be the issue now. I disabled it, and so far running. Which is odd, because I have latest Win10 and IOMMU should work with it. I'll keep this thread posted if it happens again.]]> Mon, 30 Jul 2018 21:08:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=9285&PID=54213&title=taichi-x399-stuck-on-post-a9-dr-debug#54213 <![CDATA[Taichi x399 stuck on post - A9 Dr. Debug : Nope.

Nope. Took out all PCie except for Nvidia 1080Ti. Randomly get blank screen and Dr. Debug A9 code. Try pressing reset button on board, and still get blank screen.

Looks like it has something to do with PCI-e E-SATA card. I have tried two E-SATA cards, and none of them work in any of the slots, including the 1x slot.

How to get ESATA card working?

I am no longer able to POST after installing a pcie e-sata card and changing OpRom to Legacy Only. My screen shows the Asrock logo , try to press Del to go into System Setup but all I get is a blank screen.
I've since taken out the pcie card, but it still won't post and boot up.

There is no description for A9 code. Anyone know what that mean?
