Generic BIOS archive whose name gives no model, board number or version, so its target device cannot be identified from the title alone. The RAR is 3.20 MB, which suggests a laptop or desktop SPI flash image, possibly 4 MB or 8 MB uncompressed. Before use, open the archive and inspect the image with a hex editor or UEFITool for model strings or board identifiers. Never write an unidentified dump to a chip without first saving the original, and make sure the image size matches the flash capacity exactly.
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.
