Lenovo BIOS archive for a board identified as IB760ME, with a 32 MB flash size stated in the name. The RAR is about 20.5 MB and should be unpacked before use. The name gives no laptop or desktop model, so check that the board marking matches IB760ME before using it. A 32 MB image needs a 256 Mbit SPI chip, and writing it to a smaller chip will fail. Read and save the original chip contents with your programmer first so that system identifiers and keys can be restored if needed.
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.
