input contains uefi data but no vbios could be found
the vbios might not be baked into the input!

What is "wrong guess :(" ? Thank you

What is "wrong guess :(" ?

VBiosFinder uses heuristics to determine whether or not the file contains compressed data, this is not perfectly accurate, so when the heuristic matches it attempts to unpack any data - when this fails, we know it didn't find zlib compressed data. That's a wrong guess

That's probably unrelated to the failure you're seeing though, i'll investigate and report back with what i can find.

It does look like there's compressed data of some form.
I disassembled the executable, and it is using lzexpand to inflate data from somewhere. Couldn't find the exact details just yet, as i don't have much time at the moment.

I installed this package in windows VM and compressed temp application folder.
https://drive.google.com/file/d/1wSwaijOZC3U61Szg4d1M0Wwi1pEfdv0e/view?usp=sharing
Folder contains bin files with similar name like subvendor id of gpu (PCI\VEN_10DE&DEV_1C8D&SUBSYS_836B103C&REV_A1).
Tried directly provide bin for kvm or your soft, but no result.
