BIOS firmware for the Acer TravelMate B117-M notebook, Quanta mainboard DA0ZHXMB6C0 revision C, delivered as a 3.33 MB RAR archive. Quanta uses the DA0 number pattern for its boards, and Acer sources many entry models from that ODM. The dump is intended for writing to the SPI BIOS chip with a programmer when the laptop powers on without display, loops or bricks after an update. Make a backup of the original chip before programming, confirm revision C on the PCB and ensure the image size matches the chip.
