VBIOS is exactly the same, only "last rom image"-set to 0x00 and dummy-space "RGIS" contains UEFI-image. Will work to 99,9%.

Thanks guys it's worked have nice day

I need some help here.

My 1st question: are the instructions on Post #1, also the tool on #2, up to date? If not, where is the updated instruction/tool?

Anyway, I followed the instructions from the Post #1 and downloaded the tool from link on Post #2. Extracted the .rar file to a folder in root C:\UPD. Placed my VBIOS file there too (from GPU-Z dump). Then, drop the VBIOS file to GOPUpd.bat icon. Got an error in the batch window: " File not found ...\python.exe".

I suppose it meant that I need to install Python. But that is not clear from the instruction.

Could someone clarify on this?

My video is cards:
1. MSI R7770 1GB PMD1GD5
2. XFX R7850 1GB

Thanks!

Here latest version: AMD and Nvidia GOP update (No requests, DIY) (86)

Thank you!

I downloaded the tool from page 86 (Post #1281). Ran it. Not sure if it was successful, since the msg is a bit confusing. It said "No EFI ROM found!"/"GOP is not present!!!", but still allowed "to update GOP to latest available". I've attached the Screen capture. Could you tell if it generated correct output? (I am patching XFX R7850 1GB card).

Thanks,

Bill

Some older videocards don't have GOP, so the tool will insert a new GOP-image after VBIOS and set last-rom-indicator from 0x80 to 0x00h.

Try to update your card with updated rom, sometimes the flash-memory is to small to hold the complete rom. In this case you can insert another, smaller gop-image, if this will also exceed the size, memory must changed to a bigger one.

If anyone wants to add by himself latest VEGA AMD Gop Uefi Table here is the attached file.

@MeatWar ,@Ludolf - Thank you for the help. I've successfully patched three cards (MSI R7770 1GB, XFX R7850 1GB, AMD R9 290X 4GB), using the instructions. All have the latest GOP inserted by the patching tool and all work great in my Hackintosh setup (HP Z420/Z820 - Catalina/Big Sur). Before the GOP update, I had black screen issues and could only use specific ports. Now they all work flawlessly, using any ports/combinations. Of course, I had to disable Legacy Support in BIOS (HP BIOS: Boot Order -> Legacy boot; Secure Boot Configuration -> Legacy Boot).

Thank you all for this great work! I wish I had found it sooner.

@Sylar76 Thank you, I can confirm it works on an RX 5700

@Sylar76
Could you please re-upload GOP_Updater_v1.9.6.5.k_mod_v0.4.8.rar, because the current link is not downloadable:
GoogleDrive says: The file is not downloadable, because it contains a virus. Only the owner would be able to download infected files!

So i could not download the latest GOP_Updater. You would do me a favour.

@MDoehler

I haven't that file anymore as I like to mod bios for myself but it's strange Google reports it as a virus.

Last user here: AMD and Nvidia GOP update (No requests, DIY) (90)
ask for the same file... seems that he used to perform the GOP update on two vbios and had sucess, he never reported ur issues.
Copy a link to ur Google disk drive, make a copy then of the file and transfer it then, it will report the same alert but u can now ignore and download anyway.

Hi. Where can I provide updated files? I got a GIGABYTE Radeon RX 580 8GB GAMING REV 2.0 with a production date of week 14, 2021. It uses Hynix AJR RAM. The video card is dead but I was able to salvage the untouched BIOS (no modificatoins done). GOPUpd says it has a newer GOP than what is publicly available. BIOS download is linked below.

edit: for some reason it isn't letting me post pictures or BIOS links. The AMD GOP says 1.70.0.15.50. How can I upload this?

Also can someone upload a copy of mod v0.4.8? The link sylar made says google drive thinks there is a virus in it (but we know it doesnt have one, its a false positive) and I cant find a different download link

You can also change file-extension to .txt or something else and attach the file to your posting ;)

trying link again for new rx 580 bios with gop 1.70.0.15.50.

edit: link wont work still, forum is restricting me too much. i tried attachments. rename the dot txt file to dot rom.

editedit: looks like attach worked. I had to extract the rom manually with a ch341a device so it is showing at 512kb size
