BIOS and keyboard controller (KBEC) firmware for the Quanta DAN91CMB6D0 board, revision D, in its AMD version, packed in a 2.57 MB RAR archive. Having both the system BIOS and the EC firmware helps when a laptop shows no power, no charging or keyboard faults caused by corrupted controller code. Each image goes to its own chip, so identify the SPI flash and the embedded controller on the board first. Confirm the board number, revision D and AMD platform, and save the original contents before programming.
