Firmware image for the Toshiba M305D laptop on Quanta board DA0BU2MB8F0 at revision F, slightly smaller than the other M305D dump, so compare both before choosing one. The name does not state a tested status. Such a BIOS is written to the SPI flash with a programmer when the notebook powers on without video or fails after a bad update. Verify the PCB number and revision match, keep a backup of the existing chip, and check the image fits the chip capacity exactly.
