Firmware dump for the Dell Vostro 2520 on the DV15 CP UMA Wistron mainboard 10263-1, UMA meaning integrated graphics without a discrete GPU. Wistron marks Dell boards with a five-digit number and dash suffix like this. The 1.86 MB RAR contains a BIOS image for reflashing the SPI chip with a hardware programmer. Note this differs from the 11280-1 board also used in the 2520, so verify the PCB number, save the original chip contents, and confirm the image size fits the flash.
