BIOS dump for the Dell 3490, most likely the Latitude 3490, on Compal board LA-G716P, marked OK as reportedly tested, in a 7.61 MB zip. The LA-xxxxP pattern belongs to Compal, the ODM behind this board. The image is for SPI flashing with a programmer when the laptop fails to POST after corrupted firmware. Check the board number on the PCB, compare the image size to your chip, and back up the original contents, which carry the service tag, before writing.
