BIOS archive for the Compal HLS1C/HLS1D platform, board LA-L502P revision 1A. The LA-xxxxP format is Compal's numbering for laptop mainboards produced for multiple brands, and the HLS1C and HLS1D codes name the platform variants. Extract the image and write it to the SPI flash with a programmer to recover a board that will not boot. Verify the board number and revision on the PCB, make a full backup read of the existing chip, and confirm the file size matches the flash capacity.
