BIOS images for the Dell OptiPlex 7000 desktop, D17S, with both 32MB and 16MB variants in a 13.6 MB rar. The two sizes suggest separate dumps for differently sized SPI chips, or a main and secondary flash. Identify the chip on your board and write only the image of matching capacity, because a mismatched file will not fit. Back up the existing contents with your programmer before writing, since board-specific data such as the service tag lives in the chip.
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.
