I have a Sabertooth x79 and just installed an PCie adapter for my new NVMe M.2 2TB ssd. I flashed the bios with the 4801 CAP file. And my NVMe does not show up in BIOS. However I can see my NVMe SSD in Windows Disk Management. I also cloned my old SSD to the NVME including the OS. I've tried unplugging my current SATA ssd to force the motherboard to boot the NVMe but it does not detect the NVMe even though I can see it in windows. Do you have a solution for this? I also flashed the 4701 CAP first and it didn't work so I tried the 4801 CAP file. Thank you in advance for your help.
