Dell Latitude 5421 BIOS dump for the Compal board LA-K922P, with the name stating a 32 MB image, packed in a 13.0 MB RAR. Compal manufactures this board and the LA-prefixed number follows its scheme. A 32 MB file needs a 256 Mbit SPI chip, so make sure your programmer supports the part on the board. Use it to recover from corrupted firmware or a failed update. Keep a backup of the original contents, which hold the service tag and system data, before programming anything.
