So i’ve just put together an Asus Z170-Deluxe based machine and have come across this rather frustrating limitation. I’ve installed an M.2 PCIE SSD on the mobo only to find the moment I enable RAID support (i.e. Intel Rapid Storage Technology) my mobo drops the m.2 drive on reboot and as far as the BIOS is concerned, it no longer exists. Switching Intel’s Raid support off in the BIOS and rebooting immediately restores the existence of my M.2 drive. Is there a limitation I am unaware of where enabling Intel’s RAID drivers forces the mobo to drop any M.2 PCIE drives?
I didn’t find the right solution from the Internet.
