Firmware bundle for a board with platform code GPT50 and Compal number LA-J497P, containing BIOS and EC files together with the KB9542QF embedded controller. The LA-xxxxP format is Compal's numbering. The BIOS image is written to the SPI flash with a programmer, while the EC firmware belongs to the ENE KB9542 keyboard controller, which manages power-on, charging and keyboard functions. Back up both chips before writing, check that the PCB is LA-J497P, and confirm each image size matches its target chip.
