BIOS image for the ASUS X509FAC laptop mainboard revision 2.0, described in its name as working. The 11.8 MB RAR archive holds the dump intended for programming the board's SPI flash with an external programmer when the original firmware is corrupted or the laptop fails to power on or POST. Extract the archive and check the image size against the flash chip. Always read and save the existing chip contents first, since serial numbers and other board data may live in the original.
