BIOS package for a Dell OptiPlex 7000 Tower, written in the name as 70000, with D31M also mentioned, described as an unlocked 32 MB BIOS and supplied as an 11.2 MB RAR archive. Unlocked images are typically used to recover a board locked by a password or service state. Flash with an SPI programmer only after reading and saving the original chip, and confirm the flash capacity matches 32 MB, since an image of the wrong size will not fit. Check the board markings correspond to this 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.
