BIOS archive for the Compal AAL10 platform on board LA-B843P revision 1.0, described in its name as fully working. Compal LA-xxxxP boards are produced for several laptop brands, so the platform code AAL10 helps confirm the match. The 4.44 MB rar should be unpacked and the image size compared with the SPI flash on the board. Use it to revive a board with corrupt firmware via a hardware programmer, after first reading and storing the original chip contents in case serials or keys need to be restored.
