I had to "manually" update the VIA IDE drivers to get them to install correctly. I could have missed something along the way, but this seemed easiest to me. Just go into device manager/hard disk controllers and click (one at a time) properties for VIA Bus Master PCI IDE Controller, Primary Bus Master IDE Controller, Secondary Bus Master IDE Controller....click driver tab, then update driver and point it to folder where your VIA drivers are. I was having problems with my internal ZIP on my Pro-2A even after installing newest VIA drivers. Upon looking closer, I realized it hadn't really updated the drivers at all......
