Compact archive of about 214 KB for the Dell Latitude E7440 on the Compal-made LA-9591P board. Its size is in line with a boardview file rather than a full BIOS image, but the contents are not named, so confirm after extracting. A boardview opens in FlexBV or OpenBoardView for locating parts and following nets. It may duplicate the separate E7440 CAD file, so compare the two. Verify the PCB board number before use.
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 @SCHEMATICWORLD. Enginerys does not host this file.
