Keyboard controller firmware, the EC or KBC image, for the Quanta DA0LX6MB6H1 board, a 512 KB raw binary. The name states only the kbc role, while the board code comes from the Quanta numbering pattern used across several laptop brands. The embedded controller handles power-on, charging, keyboard and fan control, so a corrupt EC image can leave a board dead. Write it with a programmer to the correct chip, back up the original first, and confirm that the board code on the PCB matches.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
