It may be useful in some exceptional cases. I think I have one of such cases. I am one of the members of the robotic soccer team from the University of Oporto, and a couple of months ago we were looking for new motherboards for our robots, because we are starting to need new hardware (on-board lan, usb2.0, etc.). We really don't need excepcional performance, but we really, really need low power consumption, so lowering the clock on a standard mainboard seemed to be the best cost/performance scenario. Could this driver be used to keep a standard p4 processor at say 25% clock speed at all times? -- Paulo Marques - www.grupopie.com All that is necessary for the triumph of evil is that good men do nothing.
