EC firmware for a Toshiba laptop on Quanta motherboard DABLQMB16B0, revision B, marked as OK in the name. At 56 KB it is a small embedded controller image rather than a full BIOS, and is used when the board has no power-on, a charging fault or a dead keyboard. The DA…MB… string is Quanta's board code. Compare the number and revision with the PCB, read the original EC or SPI contents before writing, and check that the image fits the chip.
