BIOS binary for the Lenovo IdeaPad Z500 laptop, 4.5 MB in size. No board number or revision appears in the name, so confirm the motherboard version before use. A 4.5 MB image usually means the dump combines two flash chips, commonly a 4 MB and a 512 KB part, and must be split before programming each chip. It is used to restore firmware with an SPI programmer on a board that will not start. Always back up the existing chips and check sizes against the dump.
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.
