BIOS backup file, 2.00 MB in size, whose name marks it as a saved backup but gives no brand, model or board number. The size fits a 16 Mbit SPI flash chip. A backup like this is normally taken before reprogramming so the original firmware can be restored. Open it in a hex editor to find vendor and version strings before using it on another board. Only write it to a chip of matching capacity on the same motherboard model, and read the current chip contents first.
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 @bios_laptop. Enginerys does not host this file.
