Backup BIOS dump labelled 8470, an 8 MB image with no brand, board number or version stated in the name. The figure 8470 probably refers to the laptop model, but the name does not confirm it. The size matches a 64 Mbit SPI flash. Check the image with a hex editor or firmware tool before use, then write it with a programmer only to a chip of the same capacity. Keep the existing contents of the target chip saved separately in case the image does not suit that board.
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 @biosfilebins. Enginerys does not host this file.
