BIOS dump for the ASUS X455L / X455LJ laptop, board revision 2.1, with firmware version 202, compressed into a 3.45 MB rar. The name gives both the board revision and the BIOS version, which helps match it to the installed board. Technicians write such images to the SPI flash with an external programmer to recover units after failed updates or corruption. Confirm the revision printed on the mainboard, read and keep the original chip contents, and check the image size fits the flash chip.
