Windows Server 2008 has already built-in drivers for many hardware devices but it can be that for some essential devices you need to download and install the driver manually first in order to get the device working. You can prepare the Windows 2008 (driver) installation by searching and downloading all needed Vista drivers in advance using the device names you can find using Lavalys Everest which is described in Method 2 of the Installation page in the Manual.
Hope this answers your question! 🙂
