RAR archive containing a BIOS dump for the Dell Inspiron 3520, built on the Wistron mainboard 10263-1. Five-digit numbers with a dash suffix are the pattern Wistron uses on many Dell boards, so read the number on the PCB to confirm compatibility. No ME cleaning or chip size is mentioned, so inspect the image before writing it. It is meant for reflashing the SPI chip with an external programmer. Keep a backup of the original contents in case anything goes wrong.
