Working BIOS package for Dell motherboard LA-9781P, version 1.0, a board number following Compal's LA-xxxxP scheme, stored as a 6.72 MB RAR. The name gives no laptop model, so match the board by the number on the PCB. After extraction, compare the image size against the SPI flash chip capacity before writing it with an external programmer. Keep a copy of the original chip contents, which may hold the service tag and other unit-specific data.
