Working BIOS image for a Quanta-made motherboard numbered DA0XW3MBAG0, revision G. The name gives no laptop brand or model, only the board number, which follows the Quanta DA0xxxMBxx0 pattern printed on the PCB. A tested dump like this is used to restore a corrupted SPI flash with a programmer when a board powers on without video or loops. Make sure the board number and revision G match your unit, save the original chip contents first, and check the image size matches the flash chip.
