ASRock Z97 Extreme6 M.2 SSD not shown in "Storage Configuration"

[Edward_63]

I have a M.2 SSD plug to the ultra M.2 slot.
I can choose this drive as the boot drive in the setting and also it works fine in Window 10 64-bit.

Just it is not shown in the Storage Configuration tab in the Bios, anyone who know why?

Look in the PCI-E section in the BIOS. I forget how it's worded.
