BIOS firmware for Compal board LA-9933P revision 1.0, with the VAL90 project code and A00 marking, in a 6.88 MB ZIP. The LA-xxxxP pattern is Compal's numbering, and the VAL90 code identifies the ODM project rather than the retail model. Use the image to reprogram the SPI flash chip with an external programmer when recovering a dead board. Confirm the board number and revision silkscreened on the PCB, save a backup read of the original chip, and ensure the image size equals the chip's capacity.
