ASUS X83V laptop BIOS, delivered as a 685 KB ZIP whose name also contains N80VbAS209, which looks like an N80Vb BIOS image of version 209. The name states no motherboard revision. ASUS often shares firmware between closely related models, but compatibility should be confirmed against the board before use. Technicians flash such images to the SPI chip with a programmer to recover a unit that shows a black screen after a failed update. Back up the original chip, check the PCB markings and confirm the image size fits the installed flash.
