So, I've recently built a computer for a friend of mine and figured I'd try out Optane through his computer as sort of a guinea pig experiment. I downloaded the setup executable, ran it, and got a bios error. I updated the BIOS, and I get Unsupported BIOS mode.
I tried switching AHCI to Intel Rapid Storage Technology in the BIOS settings, but when I do this I get a BSOD for "Inaccesible Boot Drive." What can I do to fix this? I have a 7th gen Core i5 processor and the Asus Prime B250M-A motherboard, running Windows 10 64-bit.
