BIOS and EC firmware for the Dell Studio 1749 on Compal board LA-5155P, project NAT02. Compal pairs LA-xxxxP board numbers with project codes on the PCB, and the 1749 appears on more than one board, so checking the exact number matters. Having both the system BIOS and embedded controller files helps when a board will not power on or charge properly. Before reprogramming either chip, read and save the original contents with a programmer and confirm the image sizes match the fitted flash parts.
