Hey guys, I'd like your input and advice on this....

On my N810 I'm running chinook, cloned to the internal built-in 2gig SD card using penguinbait's deb. I'm on the fence with diablo. I'd like to install diablo on the internal flash and keep my existing chinook install on the internal 2gig, then dual boot between the two. Can I do this? What's the best way? Input and suggestions are welcomed.
