There is another CSM bug with the AB350/X370 thread is here http://forum.asrock.com/forum_posts.asp?TID=8184&PN=1&title=warning-to-users-with-older-video-cards
Not really related besides the fact that its regarding the CSM module, but worth mentioning that there is a problem with ASRock and the CSM function on all boards it seems

It's specifically the error code 0E displayed on the debug LED. We don't know what it refers to, as it's not in the manual.

0E runs in hardware low level initialisation part of your bios (SEC / bootloader)
and it is CPU microcode not found error code dunno if teh usual "reseat your cpu / RAM" will help you if its from CSM hmm u may try to reflash your bios, otherwise fell free to try older bios version if any of them are fine |

Well I have no problem booting from defaults and my ram sticks pass stress testing, but still CSM + IOMMU disabled = 0E. I can disable them individually no problem.

EDIT: Received a response from ASRock support - they have confirmed the steps I've taken, although contradicted AMD's instructions for setting up boot from NVMe in that they aren't suggesting CSM be disabled:
I have definitely tried this configuration and NVMe RAID does not show up as a boot option. With no other disks installed, the "Hard drive BBS boot prioirity" list is empty, as is the F11 boot menu, and of course the system does not boot if I simply turn it on and let it boot. Have replied, will see if they can turn up something further.
