BIOS firmware for a Sony laptop whose motherboard is labeled DAHKCAMB6AO, a Quanta-style board number of the kind found on many VAIO models. The file is an 8 MB .bin image, the full size of a 64 Mbit SPI flash chip. It is used to reprogram the BIOS chip when a board shows no POST, a black screen or a failed update. Confirm the DA number silkscreened on the PCB before flashing, because Quanta boards with similar codes are not interchangeable. Save a read of the original chip before writing anything.
