Working BIOS and EC firmware for the Quanta motherboard DA0SW9MB6E0 at revision E; the laptop brand is not stated. The 4.64 MB RAR covers both the system BIOS and the embedded controller, which manages power-on, charging and the keyboard.

Check the PCB code and revision, find out whether BIOS and EC share one chip, and back up every chip before writing.
