BIOS dump for the ASUS X509JA laptop, supplied as a RAR archive of about 10.8 MB and labelled as working. The name gives no board number or revision, so compare the mainboard code printed on the PCB before using it. A technician typically writes such an image to the SPI flash chip with a programmer such as a CH341A to recover a corrupted firmware or a board that will not boot. Read and save the original chip contents first, and make sure the image size matches the capacity of the installed flash chip.
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 @pkbiosbdv. Enginerys does not host this file.
