The drivers may well have been on a hidden partition but by formatting the hard drive you have deleted them, thats assumming they exist anyway. I've looked on the Toshiba website click here and searched for all drivers for all operating systems and its come back with nothing. I presume therfore that the notebook uses XPs generic drivers and if you want to use Windows 2000 you will need to find them, if they exist. Regarding the graphics, this may work. click here If it doesn't work then I'm unsure as to what you can do. I presume the Toshiba is not designed to work Windows 2000 in which case using 2000 may not be an option.
