A generic 4 MB binary image called main, with no brand, model, board number or version in the name. The size suggests a 32 Mbit SPI flash such as a 25-series chip of that capacity, but the device it came from cannot be told from the name alone. Technicians usually search such an image with a hex editor for BIOS vendor strings, model names or board identifiers before trusting it. Only write it to a chip of the same capacity on a board you have positively matched, and read and save the original contents first.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
