BIOS and EC firmware archive for board DA0R03MB6E1 revision E, a Quanta numbering pattern, labelled as fully working. Including the embedded controller image matters, since EC corruption can cause no-power or charging faults independent of the main BIOS. Verify the working claim yourself: read and save both original chips with a programmer, check image size against chip capacity, and confirm the PCB shows DA0R03MB6E1 rev E before flashing.
