Firmware package for Compal motherboard LA-H104P, revision 1.0, containing both the BIOS and the EC (embedded controller) firmware in a 12.2 MB RAR archive. No laptop brand is named in the file, but the LA-xxxxP code follows Compal's board numbering. Having the EC image alongside the BIOS helps when a board fails to power on, charge or respond to the keyboard. Flash each image to its own chip with a suitable programmer, saving the originals first and confirming the PCB revision matches.
