Cannot extract my gpu rom

Open eoli3n opened this issue 4 years ago • 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 https://www.reddit.com/r/VFIO/comments/g9kwd7/gpu_passthrough_on_muxless_optimus_gpu/

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.
