BIOS image for an HP ProDesk 400 G desktop, with DNIO REV A in the name, sized for a 16 MB flash chip and packed in a 15.6 MB ZIP. The exact generation is not given, so verify the model label and board marking before use. Such a dump is written to the SPI flash with an external programmer when the PC will not boot or a BIOS update failed. Read and back up the original chip first, and confirm the image is exactly 16 MB to match the installed chip.
