http://acpi.sourceforge.net/documentation/processor.htmlA note about Intel(R) SpeedStep(TM)
When this file shows "<not available>" this does not mean that you do not own a Intel(R) SpeedStep (TM) capable processor, or similar technologies from other CPU vendors. It only means that it cannot be controlled using ACPI. For Intel(R) SpeedStep(TM), Intel(R) continues to withhold information about how to set these processor performance states when no ACPI interface is possible. So no driver for Linux is available yet, even though some preliminary reverse-engineering efforts have begun.
Вот так вот безрадостно. И везде пишут, что нужно включить поддержку в BIOS...
Но ведь под виндой доступны все множители и напряжения.
