This is actually SiS6326 driver which has to be deliberately forced on to Win2000 Pro. Choose Add/Remove Hardware from Control Panel. Click 'Display List of Drivers', choose 'Display Adapters'. Finally click 'Have Disk' and point to the contents where the zip file is extracted. It will show SiS6326. Choose it and ignore the warning that comes. Enjoy your Windows2000 in full colors.
