RAR archive containing a main BIOS read from a Lenovo IdeaPad Z500, with a timestamp in the name suggesting it was dumped in January 2015. A main read is the full content pulled from a working laptop's SPI flash, useful as a reference or for restoring a board with corrupted firmware. No board number or revision is stated, so compare the motherboard markings before programming. Extract the image, check that its size matches the flash chip, and save your own chip contents before writing anything.
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.
