Thank you very much for your help. I went ahead and posted a different question in the N800 thread.

About the flasher -- I use 64-bit Windows 7. I went to this page:

http://skeiron.org/tablets-dev/maemo-dev-env-downloads/

and downloaded the file named "maemo_flasher-3.5_2.5.2.2.exe". Will this work for what I'm wanting to do? I also downloaded the latest Diablo firmware.
