BIOS and keyboard controller (EC) firmware for the Compal CDL51 platform, board number LA-D712P, revision 2.0. The 3.58 MB RAR includes both images, which helps with boards that will not power on, have a dead keyboard or charging faults after corrupted firmware. Compal uses the LA-xxxxP pattern on boards built for several brands, so check the PCB label and revision rather than the laptop model. Read and back up the original chips with a programmer first and make sure each image size matches its target flash chip.
