I checked the toshiba site, and couldnt find anything for the webcam. Wasnt sure about the graphics.
That was what I was referring to... the maker had set his sights on running this with Vista-- but you are not alone wanting to "downgrade" to XP. Unfortunately-- they are under no obligation to write drivers so you can do so.
Therefore if you want to keep XP-- you have to go looking for alternatives to make everything work correctly. The Video driver is a major part of any Windows OS-- if it's not correct, nothing works properly.
XP is probably running a generic driver from it's own database currently-- on your machine... so this driver
should work-- perhaps a bit better.
