Dell Inspiron 15 3576 BIOS dump for Wistron board 17841-1, reported as tested. Wistron identifies its Dell boards with a five or six digit project number followed by a revision suffix, as here, and that number is printed on the PCB. Use the file to reprogram the SPI BIOS chip with an external programmer on laptops that won't POST or are stuck after a failed update. Back up the original flash first to keep the service tag, then confirm the image size equals the chip capacity so the image fits correctly.
