BIOS image for the Dell XPS 8300 desktop, sized for a 4 MB flash chip according to the file name. The RAR archive should contain a raw dump that can be written directly to the board's SPI memory with a programmer when the system fails to POST after a bad update or chip corruption. Read the original chip first and keep that copy, since it holds service tag and configuration data. Verify the chip capacity on the board, because a 4 MB image will not fit a chip of a different size.
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.
