Description
BIOS dump for the Dell Precision M5520 laptop, board LA-E331P (Compal design), supplied as an 8 MB RAR archive. The uploader marked it as tested, though that is their own claim and not something the catalog has verified. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Confirm that the board number on your motherboard matches LA-E331P before flashing, and read and save the original chip contents first so you have a way back if something goes wrong.
The catalog also lists 5 schematics, 4 boardview files, and 8 BIOS dumps for board LA-E331P.

Will this BIOS work on my board?
Only if the board number and revision match: Dell Precision M5520 LA-E331P. Dumps from a different board or revision can leave the board dead.
