- Exactly. But I think they disabled the FP portion of the chip internally,
- not through the pin. But, inside the SX is the real DX. But, this is for
- the initial production run only. They did this to get the product out the
- door faster.

- It's call product positioning. In reality, it doesn't cost them any more to
- produce the DX than the SX anyways. By doing so and splitting the price
- range they can earn business from the entire spectrum of buyers, not just
- just the higher end users.
