BIOS dump for the Dell OptiPlex 3070, labelled IPCFL-CG, which matches the motherboard identifier, and marked as tested and working. The 6.75 MB rar archive contains the firmware image intended for writing directly to the board's SPI flash with a hardware programmer such as a CH341A when the system will not POST or the BIOS is corrupted. Read and keep a backup of the existing chip first, since it holds the service tag and unique data, and verify the image size matches the flash capacity.
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.
