WARNING: You are authorized and licensed to install and use this BIOS code
|
|
ONLY on an IST PC. This utility may damage any system that does not
|
|
meet these requirements.
|
|
|
|
An IST PC is a computer which
|
|
(1) Is capable of seamlessly and automatically transitioning among
|
|
multiple performance states (potentially operating at different
|
|
efficiency ratings) based upon power source changes, END user
|
|
preference, processor performance demand, and thermal conditions; and
|
|
(2) Includes an Intel Pentium II processors, Intel Pentium III
|
|
processor, Mobile Intel Pentium III Processor-M, Mobile Intel Pentium 4
|
|
Processor-M, Intel Pentium M Processor, or any other future Intel
|
|
processors that incorporates the capability to transition between
|
|
different performance states by altering some, or any combination of,
|
|
the following processor attributes: core voltage, core frequency, bus
|
|
frequency, number of processor cores available, or any other attribute
|
|
that changes the efficiency (instructions/unit time-power) at which the
|
|
processor operates.

NOTES:
|

(1) <TODO> - Except for the SSDT package, the objects in this ASL code
|

may be moved to the DSDT. It is kept separate in this reference package
