Firmware archive for the ASUS X550JX notebook, a 3.19 MB RAR with no revision or version stated in the name. It likely contains a BIOS image for the board's SPI flash chip, but the contents should be checked before use. Use it to recover a board with corrupted firmware by writing the chip with a hardware programmer. ASUS mainboards carry a revision silkscreened on the PCB, so confirm it is compatible, and keep a backup of the original dump, which stores serial and licensing data.
