Thanks for joining the community.
I understand you are looking for win2008 server drivers for your graphics controller.
Please bear in mind Intel offers driver support for Windows 7 32 bit only. If you are looking for different operating system drivers, please through Microsoft Windows Updates.
See the list of supported operating systems for Intel graphics controllers here:
