Small 128 KB firmware file for the ASUS K45A built on Compal mainboard LA-8221P, revision 1.0. A file this size is far too small for the main system BIOS and is much more likely the embedded controller (keyboard controller) firmware, though the name does not say so. EC images are flashed to the EC's own flash or internal memory to fix power-on, charging or keyboard faults. Confirm which chip it belongs to, check that the board revision matches, and back up the existing contents before programming anything.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
