Firmware package for Compal board LA-A993P, revision 1.0, ZS040 platform, containing both the system BIOS and the KBEC keyboard and embedded controller firmware, according to the name. The EC image matters on Compal designs, because a corrupt EC can cause no power, a dead keyboard or charging faults. Flash each image to its own chip with an SPI programmer, and read and save the originals first. The image size must match the chip capacity. Check that the PCB silkscreen reads LA-A993P with a matching revision.
