For that make and model board you will have to look at the software disk that comes along with the board or go to the manufacturer's support site for the drivers needed if you are trying to install XP or an older version of Windows. The Socket 939 build I just recently replaced required a driver disk for that AMD board while the AM2 for the new one now is use saw XP go right on.
On either build the Vista installer on the other hand readily detected the two sata drives used there and now used on the new build. One question here is in regards to the Shuttle model listed in your sig that points at a far more recent system that should see support for sata already since the board is a Socket 755 Core 2 Duo/Extreme model if the same as seen at

Is this the system you are talking about seen at the link there? If that is then it may be a simple need to enable the sata controllers in the bios setup for that model if disabled.
