Things I've done:
1. I tried to reinstall Windows 8.1 Pro with CSM disabled, using a FAT32 formatted USB drive, secure boot and UEFI mode enabled.
2. The UEFI/BIOS says the GPU is operating at x8, can't find any option to specifically set it lower.
3. M.2 option is enabled.
More questions:
1. Can I use the M.2 slot and mPCIe slot on the combo adapter at the same time or do I need to remove the WiFi/Bluetooth card to use the M.2 slot?
2. Anyone have a BIOS Version with this card working? Which version? Should I downgrade?
3. The small LED indicator on the M.2 slot side of the adapter is not lighting up, should it?
I added an attachment with a picture of my SSD.
