The name gives no model or board, only a 64 MB size and the word new, so this Lenovo-tagged BIOS archive is hard to identify from the title alone. The 13.6 MB rar probably holds an image intended for a 64 MB SPI chip, which is used on recent platforms. Open the archive and inspect the content before use, compare the board number and the chip capacity with your machine, and always save the original flash contents with a programmer before writing anything, since a wrong image will not boot.
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 @biosdumpcomputer. Enginerys does not host this file.
