BIOS and EC firmware for the Compal board LA-8531P, revision 1.0, with project code Q5WT6. Compal LA-numbered boards are supplied to many notebook brands, so rely on the PCB silkscreen for identification. Having the EC image matters because a corrupted embedded controller can stop the board powering on even with a good BIOS. Flash each image to its own chip with an SPI programmer, or the combined chip if the design shares one, after backing up originals and checking that file sizes match the capacities.
