If you have the patch cable for it connect it to a vista rig and see how it identifies it. You may get by not having to have drivers if it sees it as what it is or loads a generic driver. If you get that far along set windows to do the downloading off the camera.
If you're running xp it may pick up on it and run generic drivers. Most likely not though.
Google for it or ask around in camera forums to see if any one has the drivers.
Oh and the serial numbers are either on the back of the unit or in the battery compartment.
