It's additional PCI card and requires UEFI driver to work. I guess the driver is already on the card as option ROM, but maybe it is not enabled in BIOS. There should be some options like CSM Support, Boot Mode Selection, Storage Boot Option Control or similar.
Hi dmazar, I am using your AptioFix2 + "nvram fix" (RT data to MemMapIO) efi file posted on projectosx.com. After I get rid of the EmuVariableUefi-64.efi, I could not enable "Find My Mac" functionality in Settings. Is that Nvram related problem? And could it be fixed from your aptio efi?
