I recently updated to the new bios, 1.30, that adds RAID support for the Thinkpad P50.
My P50 came with 2x pcie nvme 512gb m.2 drives. (I think they ship with the sm951, but not 100% sure)
Upon activating raid in the bios, I can select "M.2 SSD" as the mode, and successfuly create a raid volume from the 2 drives. The new raid volume shows up in the boot manager and appears to be healthy.
Macrium Reflect can even see and clone to the Raid volume.
However the installer for Windows 7, 8, or 10 cannot see the Raid volume. (Using a usb drive since i opted out of the cd drive).
I assumed this was a driver issue and proceeded to download basically every Intel RST driver I could find including the 3 on the Lenovo driver website and all the below:
64bit Intel RSTe AHCI & RAID drivers v22.214.171.1248
64bit Intel RSTe AHCI & RAID drivers v126.96.36.1999 WHQL
64bit Intel RST AHCI & RAID driver v188.8.131.526 WHQL
64bit Intel NVMe Windows Driver v184.108.40.2062 WHQL
64bit Intel RSTe NVMe drivers v220.127.116.112 WHQL for Win8-10 x64
RSTe NVMe 18.104.22.1685
Universal 64bit Intel RST Software v22.214.171.1244
Universal 64bit Intel RST Software v126.96.36.1999
Even after trying every single one of these, I still can't get Windows to see the raid volume on install. I tried turning on and off secure boot, and CSM, but made no difference. There's really not many options provided in the Lenovo bios.
I've done a normal raid setup with HDD's on hundreds of computers, but can't for the life of me figure this one out.
From what I can tell this seems like it should be possible, and I'm pretty sure is even a configuration option offered by Lenovo.
Any help would be super appreciated!
