Firmware image for the Sony MBX-177A motherboard, made by Quanta under number DAGD1BMB8B0, revision B, packed in a 592 KB zip. Quanta boards follow the DA plus code plus MB pattern printed on the PCB near the edge or under the memory. The dump serves to reprogram the BIOS flash with a programmer when the laptop stays dark or loops at power on. Note the different board code from the DAGD1A version, so check the number and revision on your board, and keep a backup of the original contents.
