Dell BIOS archive, 7.86 MB, for the Latitude E5570 and E5470 and Precision 3510, built on Compal board LA-C841P revision 3.0, platform code ADP80, UMA version meaning integrated graphics without a discrete GPU. Compal designs many Dell boards and numbers them LA-xxxxP. The image is used to reflash the SPI chip with a programmer on a dead or bricked board. Keep a dump of the original chip, which stores the service tag, and confirm the chip capacity and the UMA variant before writing.
