BIOS dump for the Dell Precision 3520 mobile workstation, Compal project CDP80, board LA-E152P revision 1.0, packed as a 16.6 MB RAR. The LA-xxxxP pattern identifies Compal as the ODM. Such an image is written to the SPI flash with an external programmer to fix a board that no longer posts or hangs after a failed update. Dell firmware regions store the service tag, so save a full read of the original chip first and make sure the image size matches the fitted flash.
