Lenovo Y50-70 FullHD gtx960m 4GB works.

[raksanyiv]

FYI!

Lenovo Y50-70 Fullhd, no touch, GTX960m 4G, extract log if needed.

Fedora 34, needed the extra packages from repo:
# dnf install ruby ruby-devel p7zip p7zip-plugins upx innoextract cmake

Extra stuff compiled under 3rd-party dir: rom-parser, UEFIExtract (new_engine brach)
git clone https://github.com/LongSoft/UEFITool --branch=new_engine
git clone https://github.com/awilliam/rom-parser

Needed to update bundler gem:
$ gem install bundler:1.17.3

Actual run:

VBiosFinder]$ ./vbiosfinder extract 9ecn43ww.exe
