ZIP archive of 2.63 MB with firmware for the ASUS N56VM, the name appending AS214, which most likely refers to BIOS version 214, though the contents should be checked. No board revision is stated. Such images are used to restore an N56 series board after a failed BIOS update by writing the SPI chip with a programmer. Verify the chip capacity against the extracted binary, as vendor update files often need conversion before direct flashing, and keep a backup of the original chip.
