NVIDIA includes MX150 as a part of the Pascal series, but the vBIOS format it uses seems to differ from the rest of the series. If I had to guess, it would have something to do with the card not being a PCI-e card.

This script works by using the differences between full (what you'd get by dumping the BIOS with GPU-Z or a similar tool under Windows) and partial copies (what you'd get by dumping the ROM under Linux) of vBIOSes. Here's a forum post on Lime Technology forums I posted about this.

If I had a full and a partial copy of the same vBIOS, I might be able to do the same for this GPU, though at that point you wouldn't need this script in the first place. I also released this script since I was able to verify that it works with my own GTX 1070, so I wouldn't be able to make the same claim of compatibility with the MX150.

I have the same issue with the "GTX 1060 Mobile with Max-Q Design". Is there anything you or I can do?

Here's what I did:

## Download the vBIOS of the GTX 1060 Mobile with Max-Q Design
$ wget https://www.techpowerup.com/vgabios/205874/205874.rom
## Download the script
$ wget https://raw.githubusercontent.com/Matoking/NVIDIA-vBIOS-VFIO-Patcher/master/nvidia_vbios_vfio_patcher.py
## Make the script executable
$ chmod +x ./nvidia_vbios_vfio_patcher.py
## Run the script
$ ./nvidia_vbios_vfio_patcher.py -i 205874.rom -o 205874_patched.rom

I'm hoping to fix Nvidia's error 43 for mobile GPU-passthrough with this.

New Laptop, this time with a normal GTX 1060 Mobile (without Max-Q design): Same problem.

[waltercool]

Same problem with GTX 1070 Max-Q

[bubbleguuum]

Same here with Quadro P600 (Pascal based).

[solarkraft]

I have a 1050 Ti Mobile and the same issue. Is there anything we can do about this?

[S-trace]

Same issue with 1050 TI Mobile. I extracted Nvidia BIOS from UEFI BIOS for my laptop, here it is FX705GE-AS.307_NVidia_BIOS.bin.zip .

please try to dump the rom on MSDOS, not windows
