BIOS and EC firmware package for board LA-C381P, revision 1A, with APW50 as the project code, in a 13.4 MB ZIP. The LA-xxxxP number is a Compal board, while the laptop brand is not stated. Having both BIOS and embedded controller firmware helps when a board has no power or keyboard issues caused by corrupt EC code. Extract it, identify which file goes to which chip, back up the originals with an SPI programmer, and check the revision on the PCB and the chip capacities before flashing.
