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

\r
    An IST PC is a computer which\r
    (1) Is capable of seamlessly and automatically transitioning among\r
    multiple performance states (potentially operating at different\r
    efficiency ratings) based upon power source changes, END user\r
    preference, processor performance demand, and thermal conditions; and\r
    (2) Includes an Intel Pentium II processors, Intel Pentium III\r
    processor, Mobile Intel Pentium III Processor-M, Mobile Intel Pentium 4\r
    Processor-M, Intel Pentium M Processor, or any other future Intel\r
    processors that incorporates the capability to transition between\r
    different performance states by altering some, or any combination of,\r
    the following processor attributes: core voltage, core frequency, bus\r
    frequency, number of processor cores available, or any other attribute\r
    that changes the efficiency (instructions/unit time-power) at which the\r
    processor operates.\r

    (1) <TODO> - IF the trap range and port definitions do not match those\r
    specified by this reference code, this file must be modified IAW the\r

	44	Processor-M, Intel Pentium M Processor, or any other future Intel\r
	45	processors that incorporates the capability to transition between\r
	46	different performance states by altering some, or any combination of,\r
	47	the following processor attributes: core voltage, core frequency, bus\r
	48	frequency, number of processor cores available, or any other attribute\r
