Tested working BIOS image for the ZSO51 project on Compal motherboard LA-A996P, revision 4.0, archived in RAR. The LA-xxxxP code follows Compal ODM numbering, used by several laptop brands, and the name does not identify the retail model. Write the image to the BIOS SPI flash with an external programmer to recover a board that fails to post. Save the original chip contents first, confirm the LA number and revision on the PCB, and check that the image size suits the chip.
