Tool is not up to date and can’t deal with modern vbios images and larger ones from 6000 up.
Also, these GOP’s can work but it differs a bit in some cases from Apple EFI GOP.
Use opencore or search in MacRumors.
Creating a Mac Pro EFI VBIOS with EnableGop - The Mac Elite
Mac Pro 5,1 on RX 6700 XT | MacRumors Forums
Thank You, but
I’m not looking for an Apple EFI boot screen — I just need a standard UEFI GOP so that my Mac Pro 5,1 can initialize the GPU and show the OpenCore boot picker.
Without a GOP, my RX 6700 OC (Navi 22) prevents the system from POSTing, so I can’t even reach OpenCore.
Does anyone have a working UEFI GOP module for Navi 22 that can be added with GOPupd, or a newer method that works with larger RX 6000-series vBIOS files?
Thanks a lot for your help!
Sorry but it seems that you have a low IQ for understanding… You’re out of this league and looking in the wrong forum.
I finally got the free time to exchange the RX580 for the RX570 GOP-updated in the system connected to the Lenovo 4K monitor and I can report that it displays BIOS and boot screen without troubles at native resolution when motherboard is set up in pure UEFI mode / CSM disabled. So I’m afraid the TCL TV is the one not compatible with the GOP and not the card itself.
Side question: whats the difference between GOP v1.70 from GOPUpd v1.9.6.5.k mod v0.5.2 and GOP 1.69 from GOPUpd_v1.9.6.5_(MAGICgop_AMD_1.69)?
Is there any advantage from using MagicGOP 1.69 vs standard more up-to-date GOP 1.70?
Hi everyone!
I have an very old Nvidia Card N9400GT that of course it doesn’t support UEFI.
I was checking the tool to mod the firmware of the GPU but it seems that doesn’t support Tesla architect.
Is there any way to add UEFI boot to this GPU?
Force it and try the GT21x - Tesla 2.0, if you can afford the risks and know how to recover the vbios.
Thanks for the reply ! I will try it
Hi again
I tried to flash a modded firmware for Nvidia GT520 but i got this issue:
ERROR: Cannot program a non-page boundary or invalid range for EEPROM.
The original bios sizes 60kb but the modded bios sizes 124kb
Also I tried with “nvflash64.exe --protectoff” but still got the issue
anyone can help me?
Yes… if forgot to warn you, the addition of an EFI image to vbios will grow the rom size, some cards have a bigger IC and can accommodate bigger one’s, others just for the original rom size.
Only solution, if the mod even works… is to solder a bigger IC for the rom, nothing else we can do.
But what happen if I replace the same manufacturer chip for a bigger capacity (128kb) ? GPU will recognize the new 128K capacity of the eeprom?
Always unpredictable results… some had good results other not at all, this is the kind of project that the users must afford to lose their time and hw for tests and see the results, sorry but there’s nothing else relevant to add to this subject because it’s all up to users decision and a waste of time and resources on a obsolete and no market value 9400 gpu…more like an hobby/spare time project, good luck.
Coming soon…
New graphics card generations are not supported. There are already corresponding tools for Nvidia. I have resumed work for AMD.

Hello!
Thank you very much @Ruin for this program.
My T-Rex Radeon R7 350 dinosaur is already using GOP 1.70.0.15.50, so I see the message:
You already have the latest available GOP!
Are there any plans to update GOP 1.70.0.15.50?
Thank you very much/

Hello!
Thank you for your feedback! You are correct, for your Radeon R7 350 (T-Rex) 
, the version 1.70.0.15.50 is currently the absolute latest available version supported by this tool.

Thanks for the tool!
Turing is obsolete. I have 0x5001F.
GOPlegacy.exe detected like a virus on my PC.
Please provide the latest versions of your GOP files so that I can integrate them into the new builds.
Nuitka Onefile: The compression method used to create a single EXE is frequently misidentified as suspicious by heuristic scanners.
Admin Access & VBIOS: The tool requires administrative privileges to interact directly with hardware firmware (VBIOS), which triggers “malicious behavior” warnings in many antivirus programs.
Unsigned Code: As a community project, the executable lacks a paid digital certificate, leading to generic “untrusted” flags
In future releases, I may use alternative build methods to minimize these detections.
