[the forum is not letting me attach the vbios files] so :frowning:221.7 KB file on MEGA)

i have modified vbios and evn thought it says i have gop it dosent boot with csm disabled in bios only the default bios works but i need the modded vbios

Modded vbios need csm enabled.
The only way to use uefi boot (without secure boot) is to use magic uefi gop 1.69
You can search it in the forum.

Your vbios has already 1.70. The only magic gop is only 1.69 version.
The tool can’t downgrade. You need an unmodified vbios that has lower gop version for example 1.68 and then update it with 1.69 magic gop.

okay i did that got the stock bios and applied my vbios mod to it and updated gop using magic gop 1.69 however this error message is there

Do you want to update GOP to 1.69.0.15.50? Y for yes or N for no: y

Fixing ID for EFI image. No checksum correction is needed.

Removing unnecessary end padding.

Data after ROM and not part of EFI! Please report it!

Recovering extra data at the same offset 0x1FF00.

File “done_updGOP.rom” with updated GOP 1.69.0.15.50 was written!

This is not an error it the same message every time.
if you updated with the magic gop It will work.

If it does not work you simply you update with the original 1.69 gop. You need to find the magic 1.69 gop.
This is my last response to this. I think it is somewhere in the thread.

i ignored the error and flashed nevertheless seems to work

Hi i have RX 580 XFX and as u can see when i try to update GOP it’s said you have newer version and won’t do anything but the problem is i can Boot with Secure boot enabled with first Bios in my card ( it’s dual bios card ) but i can’t boot with other Bios like that i modified second bios but it works well without Secure boot enable but with secure boot enable i get triple beep beep beep and can’t access to Mainboard Bios but windows will show up !

The tool cant override/downgrade the GOP, find an older vbios for your gpu model, with a lower GOP version in it.

You need the 1.69 MagicGOP, do please note that this so called “Magic Gop” is not always a solution for fixing the UEFI boot/CSM off, on all RX series models/brands around…

Hello guys.
I tried the tool to update GOP on my MSI GTX 1070 Gaming X.
But unfortunately the updated FW bricked my card (bios refused to boot up with it).
Luckily I was able to recover the GPU by inserting it into second PCI-E and booting with another (AMD) card.

I add archive with original, original updated using this tool, and original updated using official nVidia GOP update tool.
Maybe it will help you to find the problem and improve your tool :slight_smile:

@Benik3
I’m using the same updated GOP 0x30013 ( x64 ) on an MSI GTX 1060 AERO ITX OC 6Gb… no problems at all.

EDIT:

Well i dont know if you’re aware of it, but this GOP driver is only used by the EFI system bios upon boot and has no impact on loaded OS or drivers.
Usually we should update the EFI GOP to solve incompatibility issues when outputting to display devices, other than that has no impact on normal OS loaded.

Weird. I tested the vbios 2x.
PC even didn’t boot into MB bios and VGA error LED on MB was on…

I have a Zotac GT 210 card.
I have dumped the bios using GPU-Z and it was 63k in size.
I have applied the GOP update script to it but it made the rom file increase to 123k
When I try to flash the rom file with nvflash, I get the error “ROM image too large for EEPROM” and the flash aborts.

Same here.
You need to solder EEPROM chip that has at least 128KB of memory or more.
I used what i had, which is ZB25D40 which has 512KB.
Use cheap USB programmer for 25 series SPI EEPROM like CH431a to flash modded bios to new EEPROM chip, then solder it instead original.
Tested and succesfully working.

Hey folks !!
Sapphire HD 5870 Eyefinity 6 - For the life of me i can’t locate a rom file with GOP nor can i make one with GOP_Update (microcode / GOP update makes file size either too small or too large) needs to be 128k.
Can anyone help me out here?
