BIOS dump for the Compal motherboard LA-F991P, revision 1.C, packed as a 4.77 MB RAR. LA- prefixed numbers follow the Compal numbering scheme, and the laptop brand is not stated in the name. The image is meant for direct programming of the SPI flash chip with a hardware programmer when the board will not post or after a failed update. Back up the original contents first, confirm the LA number and revision silkscreened on the PCB, and check that the extracted file size matches the flash chip capacity.
