[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.
