Cannot extract my gpu rom
Opened this issue · 3 comments
Hi,
I'm trying to follow your guide, but i can't extract my rom.
Using VBiosFinder doesn't find any VBIOS.
Using cat rom > gpu.rom
gives an i/o error.
All details here

Would really appreciate your help.
Just to link issues
Update : I tried to extract gpu rom with GPU-z
on windows baremetal, it fails with BIOS reading not supported on this device
See details here
@eoli3n Also had all the same problems. Later, I found this guide which seems to work pretty well. Not sure if the VBIOS dumped by this method works flawlessly but rom-parser seems to find a valid ROM signature in there, so it's definitely worth a shot.
I had the same problem. I didn't wanted to mess around with registry, so I made a simple script using this guide. https://github.com/kyokenn/vbios_from_reg It searches for NVIDIA graphic card entry in registry and saves VBIOS as binary file.
