BIOS archive for the ASUS K43LY notebook mainboard, revision 3.1, holding a 4MB image marked OK as a working dump. The RAR is 1.70 MB compressed. It is meant for reprogramming the SPI flash chip with a hardware programmer when the laptop has a corrupted BIOS, no POST or a blank screen. Before writing, match the revision on the PCB, read and keep a copy of the original chip, and verify that the installed flash is 4MB so the image fits exactly without errors.
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.
