I have been trying to upgrade my Toshiba laptop from Vista to XP without a lot of success, so I am needing some help.
Since there are lots of threads on the net from frustrated Tosh owners trying to get to XP, including for your model, I suspect that they never made XP drivers.

Could this have anything to do with "hardware authentication?"no.
I took a look at the page mouser suggested. The problem is that many of those drivers are for Vista only. Please provide a list of the stuff that isn't working.
To get this to work, you have to pretty much forget the Toshiba site. It is mostly unhelpful and will send you over the edge. Instead, one must dig down deep into the operating system. One must manually edit driver inf files. One must deal with trying to find a driver for "Unknown System Device". Fortunately, some unnamed kind soul has done all the hard work for you.


Find msinfo32.exe on your computer and run it. Then export the info to a text file (File|Export...) and attach it to your reply.
