BIOS firmware package for the Dell Precision 7740 with motherboard LA-H281P, revision 1.0, marked as tested and working. The LA-xxxxP numbering follows the Compal pattern, so Compal is the board maker behind this Dell model. The 11.4 MB 7z archive needs 7-Zip or a similar tool and may hold more than one image. Before programming the SPI flash with a hardware programmer, read and save the original chip, confirm the image size matches the chip capacity, and check the board number on the PCB.
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 @biosfiles. Enginerys does not host this file.
