Working BIOS for a Sony VAIO with model code VJF151C01N, on a Quanta-made board DAHKDAMB6A0 revision A; the name claims the image is fully tested. Quanta boards use the DA...MB...0 numbering pattern, with the trailing letters indicating the PCB code. The 6.60 MB RAR is intended for reprogramming the SPI flash with an external programmer when the laptop fails to start. Confirm the board number and revision A on the PCB silkscreen, keep a backup of the original chip, and check the image size against the chip's capacity.
