![]() Delock PCI Express Card M.2 NVMe Carrier card SUCCESS: So I'm finally booting Mojave APFS from a NVMe SSD on my Mac Pro 3,1: Of course I still have to find out if it'll achieve what I want. navigated to a NVME.efi driver I previously extracted from MP5,1's latest firmware (PE32 body) loaded it and at least it loaded without errors. I entered the EFI Shell (I commented out the "set StartupDelay 1" line in startup.nsh by prepending a #). Even if it does not work it is an ok investment and I can resell/reuse it unlike buying a used overpriced ahci ssd. I'll buy a carrier PCIe card and a NVMe SSD and will try to access it from the EFI Shell and to boot macOS from it eventually. So my plan is to load a NVMe driver from a non NVMe disk first as at least someone seems to have already done in I'll try rEFInd or boot圆4.efi that dosdude's Mojave Patcher had already installed in my EFI partition in order to load the apfs.efi. internal Sata bay or even a USB stick) into a EFI bootloader to load a NVMe driver from there. ![]() I'll do the initial boot from a normal recognised disk (i.e. There's one thing I will consider before messing with my firmware and/or before giving up: wondering if there will be a MP7,1 and how much it will suck. I might still not dare to actually flash it just yet, but maybe in future when bricking it wouldn't hurt me that much anymore. UEFITool and dosdude1's great ROMTool so maybe or even the man himself could help me and maybe others out to get the final bits for the good old MP3,1 together. It's just that it looks kind of too easy to be true and I've gotten a bit stubborn, now that I've learned so much about the procedure. I might try to disassemble it and find out myself. gilles_polysoft used MBP114_0182_B00.fd Is it ok with the MP3,1? If I use the newest MP5,1 how can I check that it does not use instructions my MP3,1 cannot execute? I've learned those drivers are PE32 executables. However I'm still curious how the procedure works and how to decide which dxe driver to pick and from what rom. Will try to find one of those disks you named. I should simply go the AHCI route and not risk to brick a working machine. Or should I perform all steps on El Cap with the original GPU just to be sure? ![]() Does it make a difference if I did this to the already patched rom with the added apfs driver? What are the chances to brick my machine? I applied the APFS patch using Mojave with my Nvidia GT 710. I don't have any NVMe hardware yet, so I won't flash it. If I however extract the driver using "extract as is" and try again I end up with a ROM that seems to contain the same structure of the source with same checksums and sizes. When I open the patched MacPro3,1_NVME.bin with UEFITool to see if now there's a NVMe driver I can kind of find something but it does not show up as outlined above. DXEInject MacPro3,1_backup.bin MacPro3,1_NVME.bin nvme.ffs I select the NVMe node and used "Extract body" Open The MP5,1.fd file with UEFITool (Version NE alpha 55 Feb 10 2019) I find a NVMe Driver: Update: So here's what I tried so far using UEFITool and DXEInjector: Thank's in advance and thank you all for this great forum and the great information and tools! Is it ok to do it on the ROM that had already been patch with dsodudes' APFS ROM Patcher? Can I use the DXEInject approach to inject the driver I extracted via UEFITool using search and "extract body"? The NVMe driver from the latest MP5,1 firmware should work in a MP3,1 ? My conclusion is to extract it from the MP51 firmware (Applications ▸ Install macOS Mojave ▸ Contents ▸ Resources ▸ Firmware / MP51.fd) (Mojave 10.14.5). I think I'll manage to do that by extracting it using UEFITool from Firmware files that are included in the macOS Installers. I understand that I must find or extract the driver myself. I've read almost all pages of many threads and I think I understand what the missing steps are, as the google doc does not include the driver anymore. I already applied dosdude's APFS ROM Patcher without any problems, but I'm quite scared to patch the NVMe on top of it. But to be able to boot from NVMe I'll have to patch my ROM. I'm thinking of buying a PCIe SSD but would rather be able to use a NVMe instead of the AHCI ones that you cannot really buy anymore. I'm running 10.14.5 on my MP3,1 with a Nvidia GT 710 (Kepler chip works OOT but without Bootscreen).
