I'll be interested in knowing what he says too...
I have the older 8200 Elite with a UEFI BIOS, and I had to select the legacy DVD drive from the list of bootable devices.
But I still suggest you get that ISO onto a usb flash drive, run the Intel USB 3 driver tool and see if you can install Windows Server.
Any idea where you are going to find the drivers for that?
On R2, I would have said to try the W7 drivers, but on the plain 2008 version, there are no comparable Vista drivers for that model.
