BIOS firmware archive for the Dell Latitude E6520 laptop, built on the Compal LA-6562P motherboard, packed as a 233 KB zip and tagged with a CD3301 prefix the name does not explain. LA-xxxxP numbering is Compal's, the ODM that builds many Latitude boards. Unpack it and check which images it holds before reflashing the SPI chip with a programmer. Confirm LA-6562P is printed on your PCB, save a backup of the original chip, and make sure the image size matches the flash capacity.
