Organised by board number

Every board has its own thread with its files and repair notes, so you find the exact match.

Shared by working technicians

Files come from repairers who use them on the bench, with feedback in the thread.

File didn't work? We rebuild it.

Repair Pass holders send their original dump and our team builds a factory BIOS for that machine.

Frequently asked questions

What is a BIOS bin file?
A BIOS bin (or dump) is a firmware image read from a computer's flash chip. A correctly matched image can help repair corrupted firmware. No-power or no-display symptoms can also have hardware causes, so diagnose the board and save the original firmware before programming.
How do I request a BIOS file, schematic or boardview?
Post the exact board number (e.g. LA-xxxx, DAxxxx, NM-xxxx) in the BIOS & Schematics Requests forum. The community and our team respond fast — PRO members get priority handling.
Can you remove a BIOS or supervisor password?
Yes. We run dedicated sections for Dell (including unlock by service tag), HP, Lenovo/ThinkPad, Toshiba, Microsoft Surface, Apple EFI and Chromebook enrollment removal.
Are the files tested?
Files come from working repair technicians and the feedback in each thread tells you what was flashed and verified on real boards before you commit it to a customer's machine.
What do PRO plans include?
