BIOS firmware package for the Dell OptiPlex 5055 desktop in its Ryzen CPU configuration, packed in a 16.6 MB RAR archive. The name does not state a version or whether the image is a full SPI dump or an update file, so inspect the extracted contents first. When reflashing with a hardware programmer, read and save the original chip contents, confirm the flash chip capacity matches the image size, and keep the service tag data in mind, since a donor dump may carry another machine's identity information.
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.
