BIOS firmware for the Dell OptiPlex 7040 desktop, packed in a 7.53 MB ZIP. The name gives no board revision, version or ME status, so open the archive to see whether it holds a raw SPI dump or an update file. A raw image can be written to the motherboard flash with a hardware programmer to recover a machine that no longer posts. Dell desktop dumps carry service tag data, so back up the original chip before writing, and check the image size against the flash capacity to avoid a mismatch.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
