Aah! Sorry, I'm on the smartphone. I'll do that when at home and tell you what I get. Thank you veeery much
Thank you for these tables, I'll appreciate the time you needed to do that, in this very moment I don't know what to do with that, but i'ts valuable for sure.
Hello, I did it as you stated, with Radeon disabled and I get the same message, GPU-Z cannot read the vBIOS.
What's more, I've used the Dell.HD6770M.1024.100929.rom (downloadable in techpowerup.com) and everything works as supposed:

but with my extracted with PhoenixTool vBIOS I just get this:
I think I will tell you all "thank you", and I will abandon this, because it seems the tools to extract this GPU doesn't exist. It's so strange, I cannot find anybody complaining about this, everybody seems to be able to extract the vBIOS without troubles.
Following this guide "
Using the PCI sysfs interface to dump the Video BIOS ROM"
http://smackerelofopinion.blogspot.com/2011/07/using-pci-sysfs-interface-to-dump-video.html
I can see ubuntu thinks the video rom is 131072 bytes, that is, 128 KB, although it gives an input/output error and cannot be read. So weird!
EDIT: Improvements!
I could decrypt the 01658.bin thanks to this tutorial:
https://vinafix.com/threads/hp-bios-decrypt-tool.27109/
Now I can open it with UEFITool! But I don't know how to find the vBIOS with this tool. Any ideas?
View attachment 103025
I attach the decrypted bin.
EDIT 2: I found the supposed vBIOS sections. Yes, they are what we had: 64 KB, extracting them as raw, I get the same.
Code:
MacBook-Air:vbios-macos-tools Apple$ ./radeon_bios_decode < d.raw
