Hi Larry, many thanks for your "2 cents" worth! ;-) You set me off on an adventure poking around in all the dark corners of the BIOS (places I don't go) and I found (I think) the RAID setup/settings. Within the BIOS Configuration menu there is a sub menu titled UEFI HII Configuration (I have no idea what this is all about or why RAID setup would be there!). Under that I found a single sub-menu called Intel(R) Rapid Storage Technology (why not just call it RAID?) Opening that I get a menu titled (Intel(R) RST 17.8.0.4507 RAID Driver. Again there is yet another single item - Optane Volume: Intel Optane, 953.9GB. Opening that menu gives me yet another menu titled OPTANE VOLUME INFO. There it gives me a couple of non-settable bits of info - Disable mode: Safe, and Size: 953.8GB. Next there is a toggle item that allows me to either Enable or Disable the Optane memory. It is set to show Disable meaning that the Optane memory is enabled, and clicking on it will disable the Optane memory and set the toggle button to show Enable. Below that there is list titled Volume member disks: and there are two sub menu items, one for the Optane memory and the other for the SSD drive.Most windows 10 installs are with the BIOS set to RAID. Linux will not install on m.2 drives set to RAID, It has to be set to SATA for Linux to see the drive.
The sad part is Windows will have to be reinstalled if you change the BIOS to SATA and Windows was installed as RAID. The performance difference is not normally noticeable.
If you really want both Windows 10 Pro and OpenSUSE - and keep the BIOS RAID - I would suggest installing VrtualBox in Windows 10 and loading OpenSUSE as a virtual machine in Windows 10. That way the Optane Windows performance will still be there for OpenSUSE - the speed difference on new hardware virtually vs running native is not but 4% (Unless you want games like Steam - they run better in Windows). For virtual OpenSUSE - I suggest 40tb virtual drive and 4 gb ram and at least 2 CPU's - 4 if you have 8 threads. I have one 15.3. one 15.4 beta and a Tumbleweed VM all on my 1TB Intel 670 nvme on a Dell i5-8350 with 32gb ram and a Windows 10 VM and a Windows 11 VM (patched to allow no TPM).
My 2 cents.
