ROM image labelled for a Dell 3521 notebook, with the tokens 0720 and A02 in the name, where A02 most likely refers to the Dell BIOS revision. The file is 4.50 MB, an unusual size that suggests it may be a partial region or an image that needs trimming before it fits a standard SPI chip. Check the layout in a hex editor or firmware tool before flashing. Back up the existing chip with a programmer first, and only write it to a board you have positively identified as the matching model.
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 @biosarchive. 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 →
