BIOS archive for the Dell Vostro 1520, Intel version, compressed to 993 KB. No motherboard number or revision is given, so identify the board from its PCB label before use. The image serves for reflashing the SPI chip with an external programmer when the laptop powers on without display or after a failed update. Back up the original contents first, confirm the Intel platform matches, and check the extracted file size equals the flash chip capacity so it will fit.
