The easiest way to obtain NVIDIA VROM:

  • Install proprietary NVIDIA graphics driver (I used NVIDIA-Linux-x86_64-430.50.run)
  • Load driver (i.e. modprobe nvidia_drm) to initialize GPU
  • echo 1 > /sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/rom
  • cat /sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/rom > vbios.rom

That's it!

# file vbios.rom 
vbios.rom: BIOS (ia32) ROM Ext. IBM comp. Video (208*512)

This does not work on most muxless devices

At least it works on MSI GP72 7RD and DELL XP 9570.
