I will prefice what I'm about to say with this: it is only how I see things as a non-Linux usin', non xTerm usin' idiot. But this may represent some of the things that are being taken for granted by those that understand the process better than I do.
I was gung ho to come home tonight and give this install a try. But I'm now afraid I would run into the experience you are having. If you read this whole thread very carefully I think you find that:

1. The downloaded files need to go to a specific place. I have no idea how to put them there.

2. The card might need to be formated in 'windows' I'm not sure exactly what that means. For example, I don't know if maybe a stock card comes this way or whether I need to use my XP lap top or my N800 to do this.
3. There might be confussion about whether mmc1 in the n800 means the internal card or the external card although I am assuming it means the internal card.
4. I'm not sure if the download files are zipped or not. I did try to start the install process earlier today but the first nstall file would not install. The detail said it was over 1500 GB in size. I know that doesn't make sense, but that's what it said.
5 You need to be certain that the downloaded files are the correct size. But I don't know how to use xTerm to verify this.
But I suppose if I used Buns method of downloading to my XP computer and then transfering could work, but as I said, I wouldn't know where or how to put the files in the right place.
6. Penguinbait mentions that after uninstalling this it leaves some things on the IT which may not be a big deal but I wouldn't know how to change that latter if needed.

Anyway, I guess for those that can deal with the above things this is an easy install , but not for me. I'll probably sit this one out for now. But I'll be quite interested to see where it goes.

PS- I'm quite impressed and thankful to Penguinbait for offering to help people directly. Who knows, maybe I'll take him up on that sooner or latter.
