ASUS BIOS package labelled only with the model code A1502ZA, stored as a 7z archive of about 7.53 MB. The name states no board revision, flash size or firmware version, so the contents should be inspected before use. Technicians typically extract such an archive and write the image to the SPI chip with a hardware programmer when a laptop will not POST. Make sure the image size matches the chip capacity, and read and save the existing firmware first so the serial data and original state can be restored.
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 @efibios. Enginerys does not host this file.
