ehm...
i'm very noob and after being frustrated tryin' to install NitDroid on my Nokia N800, finally i did it! ^_^.

@ gpmartinson one of the MAIN goal is to setup correctly the memory card (MMC) during the partitioning process That's why you can only see the NITDroid logo after turing on the tablet. Maybe It's flashed but it can't access to the MMC

ehi, linux people! please accept my post as a feedback. Often it's very hard to "translate" your guides because they are NOT standard.

Well, i solved everything when i installed Ubuntu (actually 9.04). I used a Debian first, but some commands are different despite of Ubuntu.
Another big problem is the "name" of the device used by Debian when you connect the tablet: sda, sdb, sdd... etc. i couldn't mount/umont anything :°(

Now all works fine =D

Great job guys!
