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:

Quote
Dear Tim,

Thank you for choosing ASRock and contacting us.

Please clear CMOS to load BIOS default setting and boot into BIOS setup.

  • Adjust the following setting to make your system boot into your NVMe RAID again:
  • Advanced tab>SATA Mode to "RAID mode"
  • Advanced tab>AMD PBS>NVMe RAID mode to "Enable"
  • CSM>Enable
  • Launch Storage OpROM Policy>UEFI Only

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.

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.

Is this only for booting off of nvme raid?  I can validate that csm off and iommu on or off works on my box without the raid..

some guy here had similar issue and he resolved it with replacing some faulty ram

its wort to try to clear CMOS and run one stick at a time

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

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.

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
Main Rig: AMD Ryzen 2400G | ASRock Fatality X370 ITX/ac UEFI 4.90 | Corsair LPX DDR4 2400@3200 1.35V | Corsair RM650i PSU | CM ML120L AiO Cooler

I'll have another play and see if I can pin it down to just CSM or CSM + a combination of things. I'm fairly certain I can reset bios, then disable CSM only and it will throw the code but I'll confirm.

Gotta play their game if you want them to put time into fixing the issue...

It'd be good to have some more solid confirmations for them -?are you guys both willing and able to confirm that after a BIOS reset that disabling the CMS causes the error to be thrown? It might take a couple of reboots if you haven't changed any other settings... mine did boot after disabling CSM and I even got as far as installing win10 but then it threw the code again next boot and I had to reset the BIOS to get it going again.

Your RAM, SSD, and PSU specs might be handy too, JayB33

I can disable CSM on its own successfully, but not CSM + IOMMU together after a BIOS reset. I emailed ASRock already about it and they told me to remove all devices and try again because they have tested these settings with no BIOS code error. There may be other combinations that cause the error, but I do not wish to remove any devices from my system just to test this issue, because they should run fine, I need it all connected, and I don't want the downtime.
