BIOS for the Dell OptiPlex 3050 desktop, for the motherboard with Dell part number VJ40T at revision A00, in the micro form factor (D8-MFF-BF). The RAR archive is about 15 MB, so it may hold more than one image or a full dump with the ME region. Check the chip capacity and the size of the file you choose before programming. Read and save the original chip first, because the service tag and system configuration stored in it may need restoring after the flash.
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.
