BIOS dump for the HP 290 G3 desktop with the BAKERMS board at revision A, also tagged M11, described as fully working. The RAR archive is 16.7 MB, so check which image inside matches your flash chip. Technicians write it with an SPI programmer to recover a system that powers on without display after firmware damage. Keep a copy of the original chip first, since it may hold serial and licence data, and confirm the board name and revision before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
