Nevermind guys, I see now that this has come up many, many times over the years - I just wasn't using the right search terms.
Nearly all of the links from prior threads on this topic are now dead, so before I go hunting down an active source let me back up and expand the scope of my question: What is the best source for installing a minimalist but complete version of XP Tablet Edition?
-I see that the original IBM restore discs are a 7-CD set and are reported to contain a lot of bloat, but are possibly the only source for some device-specific drivers.
-Is there any difference in the Tablet Edition 2005 installs from different manufacturers? I see links to downloadable packages from Dell and HP, but nothing from IBM - are they all essentially the same or should I prefer ones from IBM?
-I read K0LO's guide but that starts from a point of already having T.E. installed.
-I read much of the thread on WinMatrix about converting XP Home/Pro to Tablet Edition (Link to that thread)
but there is just so much information and is not specific to the ThinkPad.
Basically I'm not sure of the best method for install Windows. I don't use this machine anymore, at all, for anything, but just want to keep it around and bootable for exhibition as a classic piece of legacy hardware. At most, I will toy around with the Android_x86 build on a separate HD partition. I love tinkering with my old ThinkPads but at this point I've been researching SSD and OS options for this computer for four days straight, which I'm realizing has been a gross overinvestment of time given the life magnitude of this little project. If someone in-the-know could just hint at the optimal XP T.E. installation option for me I would really appreciate it, thanks!
