BIOS and keyboard EC firmware for the Dell Alienware 17x on the BAP20 platform, Compal motherboard LA-D753P, stored in a 4.90 MB RAR archive. The EC firmware controls power-on, charging and keyboard functions, while the BIOS governs boot, so both are useful when a board is dead or will not post. Flash them to the right chips with an SPI programmer after saving the original contents. Confirm the LA-D753P marking on the PCB and that image sizes suit the installed chips.
