OK, stupid questions but I can't figure them out before trying to install ... Do you need to install Diablo/Community SSU before (or, for that matter, after) installing Diablo Turbo?
If you're running your system off an SD Card (dual booting), can you just install Diablo Turbo directly into the SD-based OS?
If you have to install it on the internal flash memory (i.e., not on a card), or you do install it there even if you don't have to, does it positively impact the N8x0's performance when you run the SD-based OS? Thanks!
