RAR archive of 2.91 MB holding a BIOS dump for the Dell Inspiron 5520. The name lists no motherboard number or revision, so check the board fitted in your unit before using this image. A dump like this is written directly to the SPI BIOS chip with an external programmer when normal updating is impossible. Read and save the existing contents first, since they hold the service tag and system identity, confirm the file size matches the chip capacity, and verify after programming to catch a poor clip contact.
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 @bios_laptop. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
