8MB BIOS image for the Quanta-made DA0Y0MMBAG0 laptop mainboard at revision G, compressed in RAR format. The capacity points to a 64-Mbit SPI flash chip, the size the dump must match to be written correctly. Quanta uses the DA0 code followed by a project name and MB for motherboards built for several laptop brands, so check the PCB marking instead of relying on the brand. Use it to repair a board with corrupted firmware through a programmer, after first reading and saving the chip's original data as a fallback.
