ROM image for the Lenovo G500 notebook, 4.5 MB. The file name gives only the model, with no board number, revision or chip details. The odd size suggests a combined dump covering two flash chips, typically 4 MB plus 512 KB, which has to be split to match each device before writing. Use it to recover a corrupted BIOS with an external programmer. Read and keep your board's original contents first and verify that chip capacities match the split parts.
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 @biosbigarchives. Enginerys does not host this file.
