BIOS and EC/KBC firmware package for the Acer Aspire E1-571 on Compal motherboard LA-7912P, compressed into a 2.88 MB RAR. Including the embedded controller, or keyboard controller, firmware is useful because this firmware handles power-on, charging and keyboard functions, and a corrupted EC can leave a board dead. Compal uses the LA-xxxxP numbering pattern. Flash with a suitable programmer, keep a backup of the original chips, and ensure each image matches the size of its target chip and the PCB board number.
