Original BIOS read from an ASUS K42N, 2 MB in .bin format, matching a 16 Mbit SPI flash chip. Original dumps like this serve as reference copies or for recovering a board whose firmware has been corrupted. The name gives no board revision, so check the main board marking before programming. Donor images carry the source unit's serial and system data. Save your own chip contents with the programmer first so the board can be returned to its previous state.
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.
