BIOS image for the ASUS X509FA laptop sized for a 16 MB flash chip, packed as a 5.35 MB ZIP. The name gives no board revision, so compare the motherboard markings with the model before use. Technicians write such dumps to the SPI chip with an external programmer to fix boards that show no display or stop after a failed update. Confirm the installed chip is 16 MB, since a mismatched image will not fit, and save the original chip contents before flashing.
