Win10 won't recognise RAID array

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all. Hope I've posted in the right place this time.

I've a Taichi X399, 3.50 BIOS. I've finally set up an NVMe RAID 0 array.

When I start to install Win10 from a recently produced USB drive, before installing the drivers, the individual drives in the array are detected, fine.

The three RAID drivers install, one after the other, exactly as in the manual.

After the last driver installs, no RAID or other drives appear, nothing.

I have the latest RAID drivers. I have tried resetting the BIOS and following the instructions in the manual scores of times.

Just once, the RAID aray appeared. Don't know what I did differently, but excited, I selected it and tried to move on with the Win10 install. "No suitable drives detected" (or something like that).

I've tried disabling CSM. Nothing. Might it be something to do with IOMMU, even though I'm using a recently downloaded Win10 image?

Cheers
