Bios requirement M90q Gen 3 Desktop (ThinkCentre) - Type 11U6

Greetings to the entire community.
I have a Lenovo M90q Gen 3 Desktop with BIOS issues.
I’ve tried repairing the BIOS with an exe from the official website. After decrypting it, I couldn’t find the appropriate BIOS region to repair it. If there’s any experience available to guide me, I’d appreciate it and would financially support you for your time.

Get the bios file, extract with AMI PFAT Extract / AMI BIOS Guard Extractor then follow notes here

I performed the decryption, then edited the resulting BIOS, deleting the end of the file. It’s now the same size as the original BIOS region.
I have a question: The header is different. Is there any problem with this? Will it work?

Thank you very much for your help

What are the “bios issues”?

Doesn the machine still boot?

Did you dump with software or programmer? your firmware? Post a link to this dump or attach it here.
