Firmware set for the Compal LA-A996P mainboard, revision 4.0, with the project code ZSO51, containing both the BIOS and the KBC image, meaning the keyboard controller or embedded controller firmware. LA-xxxxP is the Compal board numbering style. Having both images lets you restore the main SPI flash and the controller firmware when the board shows no power or no display. Use an SPI programmer, read and keep the original chips before writing, and check that each file size suits its target chip before flashing the 2.97 MB archive contents.
