This is what I did to get Windows Server 2012 on a Dell E6500 to load the Intel 4 series Express set
Downloaded the latest Windows 7 64 bit drivers and install them to the point you get the doesn't meet requirements error. This extracts the files under c:\Dell.
Go into the graphics folder and find the INF file and open it with notepad.
INF file was named d2869-64.inf
Find these lines
; no install on XP
; no install on Win8
Change the 0 on the last line to 2. This makes it work on Windows 8 OR Windows Server 2012
But you are not done, you have just broken the digitally signed driver hash that is in the cat file, thus it will not match and when you click on the inf file and select install you will get a hash error and it WILL NOT INSTALL.
Now ready your machine for a restart and go to the lower right hand corner of your screen and expose the charms and click on settings go to the bottom and select change PC settings entry, select General, go to the bottom and select "Restart Now" Follow the directions, when the system comes up it will give you a list of options, pick disable Driver Signing and let the system come up.
Then go to your modified INF file right click on it and pick install, acknowledge the warning that the driver is unsigned. It installs and if you are doing what I was doing your dual monitors connected to a dell docking station with a Dell E6500 laptop docked in it immediately worked!
Glory and Victory and 3 hours of my life that I will never get back. Use this technique at your own risk, although I am working without blue screens so far there is not guarantee that this won't break your system. Be careful out there.
Thanks to the many google postings on this issue that led me to the final answer.
