Any chance you know if any driver can activate a GPU in this way? Only basic VGA support should be good enough for most un-flashed card users.

Will there be NVME booting EFI for 2010+ Mac Pro on High Sierra?

Still no. GPU ROM could be loaded from anywhere, but without GOP driver it will not work. But, there is a chance to avoid flashing nvidia cards, as rom could be placed in refind drivers partition.

The driver extracted from MacBook Pro's EFI Firmware using UEFITool.
NVMe booting will not work with dosdude's way. NVMe driver must be loaded by EFI to locate target drive with OS. If place NVMe driver to EFI-partition of the target drive, it will not load, as original efi bootloader will not detect these drive. So, rEFInd on separate drive is the only option. In my setup, i placed rEFInd to industrial IDE SLC Disk-On-Module. And it works perfectly.
I am now using the 1080Ti, pretty sure the ROM support GOP. Any direction on how to do that? I can do the tests. I have Mac EFI GPU on hand for emergency recovery. Also know how to install and use rEFInd.
In documentations (uefi) there is a mention about "gopdriver.efi". But, i can't find it anywhere... Only gop-supported roms from intel, nvidia, amd... The last key and nowhere. Im bit confused.
Well. Fusion drive with Samsung SM951 AHCI and Intel 750 NVMe resolve problem with unflashed NVIDIA GPU, as there is no need to use rEFInd bootloader anymore. But, since i have now a flashed card, i'm still using rEFInd and booting from Intel 750 NVMe ssd. Also, i'm now using Apple's NVMExpressPCI.efi driver. In next few weeks, will test Intel Optane drive.
so basically what you are saying is that as long as there is a ahci in a fusion drive array : lets say
one sm951 ahci and 3 sm951 nvme it should just boot fine with regular system
and no tweaks?
From memory, someone tested it is not necessary to run with natively OS driver. By using the 3rd party NVMe driver in older OS can still achieve the same thing. However, I personally really don't suggest anyone do this. That 3rd NVMe kext work really well for someone, but quite opposite on the others. Really not worth to take the risk for virtually no benefit to boot from NVMe.
I used to agree completely with this, but the high volume storage industry fairly quickly adopts the latest interfaces.
After all, most storage devices go into new systems - not into upgrading older systems.
I think that we're reaching the point where AHCI devices are becoming less common, legacy devices.
So, it's not that NVMe is faster (it often isn't in the real world) - it's that AHCI devices are becoming harder to find and are sometimes more per TB than NVMe devices.
Aiden, I agree wholeheartedly, but NVMe PCIe SDD's are still several quantum leaps ahead in speed compared to cMP's SATA II and as you stated .. AHCI M.2 SM 951's are both old and rediciously expensive unless employed in a viable PCI-switch enabled x16 link width carriers .. . but that PCIs x16 carrier just adds $$$$$ to the overall cost.
Considering that High Sierra now "sees" NVMe devices . . . AND that it is no great challenge to get Sierra 10.12.6 also"seeing" them .. the future "economic+ decent speed" path lies with NVMe.
My best HDD spinner gets around 100Mb/s . . my Samsung 960 EVO M,2 gets i excess of 1.4Gb/s write / 1.5Gb /s read.
it looks like we may soon be able to ( apparent ) natively boot from PCIe NVMe M.2's & 2.5 " SATA's.
( check out " Next-loader-master " ! ) . . . and then teach me how to master the Terminal !
)Coders are from another far, far away planet
Of course the only way to take real advantage of the increased M.2 PCIe speed is to totally do away with spinner HDD's in the closed system. That is the direction in which i am headed.
Then I'll have a nice big, empty space to let those sexy, grey cMP Apple fans cool down my hacked HD 7950 down.
Ok they've done it :

Gilles @ polysoft injected the NVME driver in EFI so you can now boot from a cMP in NVME without any trick.....
