VBiosFinder (linux)

This tool attempts to extract a VBIOS from a bios update
Laptops with NVIDIA Optimus graphics often have the dGPU VBIOS integrated in their system BIOS, this makes extracting the VBIOS a complicated process. Provided you have a BIOS Update for your laptop, this tool might be able to automagically extract all available VBIOS from it.

Dependencies

  • Ruby
  • bundler ^(a ruby gem) ⁻ p7zip ^(optional)
  • innoextract ^(optional)
  • upx ^(optional)
  • UEFIDump ^(note: UEFIDump can be found in the branch new_engine)
  • rom-parser

Note

Some dependencies might not offer a package for your linux distribution ^(like UEFIDump and rom-parser). The binaries can be placed in ./3rdparty to avoid having to install them.

Usage

  • Run bundle install --path=vendor/bundle to install the required ruby modules ^(once)
  • Run ./vbiosfinder extract /path/to/bios_update.exe to attempt an extraction
  • A temporary working dir is created at ./tmp-vbiosfinder which can be removed inbetween runs
  • Extracted VBIOS roms will be placed in ./output
