BIOS image shared by the ASUS X509FJ and X409FB laptops, board revision 2.0, marked as OK. The raw BIN file is 16MB and can be loaded directly into an SPI programmer without unpacking. ASUS uses one main board for related 14-inch and 15-inch models, which is why both names appear here. Use it to recover a laptop with a corrupted firmware that powers on with no image. Check the revision printed on the PCB, read and save the original chip first, and confirm a 16MB flash part is fitted.
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_laptopomi. Enginerys does not host this file.
