+ WARNING: You are authorized and licensed to install and use this BIOS code

+
+        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:

+        specified by this reference code, this file must be modified IAW the
+        individual implmentation.
