Raw BIOS dump for model 6540b, 4.00 MB in .bin format, with no board number, revision or version given. A 4 MB image corresponds to a 32 Mbit flash chip. Technicians write such files with a CH341A, RT809 or similar programmer to revive boards stuck with no display or dead after a bad update. Read and archive the original chip first, check that the chip capacity matches the image, and confirm afterwards that the written data verifies correctly against the file.
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 @biosfilebins. Enginerys does not host this file.
