BIOS image for the ASUS K53SM laptop, with 214 in the name most likely being the BIOS version. The file is 4.00 MB, matching a 32 Mbit SPI flash chip used on boards of this generation. It can be programmed directly to the chip with an external programmer to revive a board with corrupted firmware. Save the existing contents before writing, confirm the motherboard model on the PCB, and make sure the target chip is the same capacity, since a mismatched image will not fit.
