XPS 8930, where is Intel Optane in BIOS?

Question: Can I swap the Optane module or SATA drive with another module or drive?   

Once an Optane module and a SATA drive are paired, the drives are not interchangeable without unpairing the drives first. The paired set can be moved as a unit from one system to another like a model system.

Question: How to I pair the Optane module and the SATA drive?  

Optane modules can be paired and unpaired using the Intel Rapid Storage Technology or Optane version 15.5.xx.xxxx or higher user interface. You can also unpair the Optane module using the F12 menu, Device Configuration option, to access the Optane configuration pages of the BIOS.

Once in the Optane BIOS Setup, select "De-concantonate" to unpair the Optane module and the paired SATA drive.

Question: Can I clone and image my paired drives?

When duplicate drives, make sure that the drive being duplicated is unpaired before beginning the imaging process.

Question: What happens if I try to boot the system with a paired and an unpaired device?

If a system is booted with one paired storage device and one unpaired device the computer will not cleanly boot to the operating system.

Question: What are the requirements for paring SATA drive with an Optane module?

• The system must have a Kaby Lake or newer central processing unit (CPU).
• The BIOS revision must support Optane.
• The Intel Rapid Storage Technology (IRST) driver must be at least version 15.5.xx.xxxx or higher.
• Your system must have Windows 10 version 1607 or higher.
