I've got a problem with some machines in work, the IBM Thinkcentre and Netvista series, they both have onboard Intel Extreme Graphics. The problem is that if I include the path to the Intel Extreme Graphics drivers in the oempnpdrivers line of sysprep.inf and run the mini-setup, upon bootup the PC hangs, so I have to turn it on and off, anyone have any ideas to get around this? I've found someone with the same issue here, but can't get his solution to work. http://www.toussaint.ca/unattend/IntelExtremeSysprep.html
