Ok. Let's start over. Last night did a fresh install of Monterey, all good (with the same quirks for booter RebuildAppleMemoryMap and EnableWriteUnprotector). Added Device Properties and boot args for HD7770, connected de dGPU and all works, everything fine, cool video output, the card is...

1. SetupVirtualMap+EnableWriteUnprotector: Can't boot, got - EXIT:BS:START 2. SetupVirtualMap+RebuildAppleMemoryMap Can't boot, got - https://imageupload.io/JSiO7brQgM5Mgte 3. EnableWriteUnprotector - Same as nr 1 4. RebuildAppleMemoryMap - Same as nr 2 NVRAM reseted twice for every...

Tried all eays, Rebuild enabled, write disable => kernel panic write enable, rebuild disable => exit:start:bs i did not reseted nvram, should i?

I tried one without another but i cant boot aymore (REubil.. EnableWrite..). I got a kernel panic or EXIT:BS:START

Ok, i'll disable de RebuildAppleMemoryMap, maybe that's why macos wont boot without usb, although i copied the EFI folder in EFI partition from MacOS. I'm using Catalina. Right now i'm installing Legacy Video Patch.. but got an error something with apple event runtime error..

Okkkkk, so i managed to boot and install as you suggested with iMacPro1,1 and this quirks https://imageupload.io/HakP65f3XXCbdIm buttt the video output is verry poor.. i only have 1280x1024 https://imageupload.io/tjsot6SFxKlbPU1

Ok. I’ll do that this evening, one question though, maybe obvious but, i should remove the boot args too for the dGPU when i remove it from hardware, right? I’m asking just to be shure.

Quirks from which category? an what SMBIOS should i try? remove the dGPU from efi or from motherboard?

Tried with both Catalina/High Sierra

I’m booting always thru boot menu, F11 for my mobo… reseted the nvram, but same error. i even removed the all ssds from computer, but nothing, with hfsplus i think it’s a no go… This is how my boot menu looks like, maybe it helps. https://imageupload.io/aMvYVNVev30jetk

here it is

Right now i’m at work i’ll post the efi a bit later. Regarding efi driver, if i use HfsPlus.efi i get this error and opencore wont boot, just halt like this: P.S.: this is not my error, the image is from web, but it’s the same as mine.

Ok. So, first attempt with HfsPlus.efi according to guide => opencore doesn't load at all. Swaped HfsPlus.efi with HfsPlusLegacy.efi. This did the trick, now OpenCore loads correctly. Pick the recovery image, and then i got this: https://imageupload.io/w8WNTgXAjPvOEif I did not catch the last...

One question though, about SSDts. In Dortania says that CPU-PM(Run in post-install), so i understand that it is no needed for install, only after?

I tought that it is what i have. Ok, no problem, anyway, when i tried to build the verry first efi for this desktop i followed the Sandy Bridge (simple one) guide, but same thing. I'll do another efi from sctratch right now, following Sandy Bridge guide. Thanks for this little but verry...
