Embedded controller firmware for a Compal LA-971P board, built for the Microchip MEC5085 keyboard and power controller, supplied as a 234 KB RAR archive. The name marks the dump as ok, meaning it was reported working. The EC image governs power sequencing, battery charging, fan and keyboard, so a corrupted one typically leaves a board dead or stuck without power. Before writing, read and save the existing contents, compare the board number on the PCB, and note that some boards hold the EC code inside the main BIOS chip.
