As you don't appear to have had an answer since January I'll give it a go. You can use most Enigma 2 images, but there can be complicated boot requirements. The Nbox 5800 has different bootloaders and dependant upon what image you are trying to load it may have different needs. Pick one you think you like from the E2 range, for example, and then use Google to learn how to boot to that particular loader. BTW I would always run images of USB it gives you more space than Nand which can cause green screen crashes when it runs out of memory. OpenPLi and Hyperion are 2 I can think of. Have fun!
