Main system BIOS dump for the Dell Pro 16 PC520 notebook, a 32.0 MB binary intended for the primary SPI flash rather than the EC. The name gives no board number, revision or ME status, so verify it against your unit. Technicians use such images to recover boards with corrupted firmware, endless boot loops or failed updates, writing the chip with a CH341A, RT809H or similar programmer. Always dump the existing chip first to preserve service tag and other data, and confirm the chip is 256 Mbit.
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 @anztechnology. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
