I just UPgraded mine with XP also and actually found all the drivers on the Toshiba recovery and applications/drivers media instructions disk(s) that came with the machine. Everything is running except being able to crank up the screen brightness. The drivers are found in the directory (folder) called COMPS1. You can either let the disk startup or go to the folders and the individual directories and double clicking on the file you want to run. If you let the disk run there is a menu system that will install the drivers also. It actually works. The disk is meant for Vista but works just fine on XP.
