That program will tell you about on-chip cache. I'm not sure it will be able to tell about off-processor cache (typically L2). System board manufacturers and system integrators are often cagey about it, since the average purchaser hasn't a clue, and since the details can provide performance advantages over competitors.
So it isn't always easy to find out EXACTLY what's in there, or how its supported in peripheral hardware.
