BIOS dump for the Dell Precision 3520 mobile workstation, with the platform tags DV15 and MLK and the Wistron-style board number 11280-1. Dell sources several Precision and Latitude boards from Wistron, whose numbers take this five-digit-plus-revision form. The image can restore a laptop that will not POST, using a programmer on the SPI chip. Read and save the original first, since it carries the service tag, check the PCB number matches, and confirm the file size fits the flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
