BIOS package for a Dell laptop board numbered LA-9933P, revision 1.0 (A00), described as fully working. The archive is 21.7 MB, so it likely holds more than a single image, and the contents should be checked after extraction. LA-numbers follow the Compal pattern, so Compal is the ODM for this board. Before writing, back up the original SPI chip, compare each image size with the chip capacity, and match the board number and revision on the PCB, then flash using a programmer.
