Here's what I used to get this combination working for the benefit of anyone else wanting to do it.
The Vista setup disk (mine has SP1 integrated, FWIW) contains enough to get the system booted and operational. You'll need to add the following four drivers:
* R195926 Intel system chipset
* R196472 Realtek audio suite
* R195931 Realtek network driver Note 1: as of 24 Dec 08, this is not the latest release for the 8111 chip. That must be downloaded from Realtek "Install_Vista_x64_6213_1119.zip" Note 2: in the machine I tested this, the NIC refused to run at gigabit speed, regardless of the driver used. It could be a specific hardware problem with this one instance, but it looks more like a BIOS issue to me.
* "winvista64_15121.exe" from Intel's site for the onboard X4500HD graphics.
Order of installation should be 1) chipset, 2) network, 3) everything else.
That's it. You'll have a fully working system, with the possible exception of the network being limited to 100mbit.
One comment also -- with the E7300 processor I chose, this is a very fast inexpensive system. The WEI for it is 4.0, with the processor at 5.5, memory at 5.9 (aftermarket 4GB of high performance memory), disk (the 250GB Seagate, which happens to have the fastest media rate of the common options available) 5.9, business graphics 4.1, gaming graphics 4.0. That's a very good score for a sub-$400 system. With the exception of the network problem, this is definitely a five-star review of this product.
Just curious did you see device errors in device manager related to the chipset? I never had to load the chipset on my system
They are minimally functional with the generic drivers that are included with the Windows setup disk. You should install the specific Intel chipset driver to achieve full performance.
