memory and I/O transactions as well as interrupt messages pass between the 

processor and chipset over the FSB.

• Storage conditions — Refers to a non-operational state. The processor may be 

installed in a platform, in a tray, or loose. Processors may be sealed in packaging or 

exposed to free air. Under these conditions, processor lands should not be 

connected to any supply voltages, have any I/Os biased, or receive any clocks. 

Upon exposure to “free air”(i.e., unsealed packaging or a device removed from 

packaging material) the processor must be handled in accordance with moisture 

sensitivity labeling (MSL) as indicated on the packaging material.

• Functional operation — Refers to normal operating conditions in which all 

processor specifications, including DC, AC, system bus, signal quality, mechanical 

and thermal are satisfied. 

• Execute Disable Bit — Allows memory to be marked as executable or non-

executable, when combined with a supporting operating system. If code attempts 

to run in non-executable memory the processor raises an error to the operating 

system. This feature can prevent some classes of viruses or worms that exploit 

buffer over run vulnerabilities and can thus help improve the overall security of the 

system. See the Intel

®

 Architecture Software Developer's Manual for more detailed 

information.

• Intel

 64 Architecture — An enhancement to Intel's IA-32 architecture, allowing 

the processor to execute operating systems and applications written to take 

advantage of Intel 64 architecture. Further details on Intel 64 architecture and 

programming model can be found in the Software Developer Guide at http://

developer.intel.com/technology/64bitextensions/.

• Enhanced Intel SpeedStep

 Technology — Enhanced Intel SpeedStep 

Technology allows trade-offs to be made between performance and power 

consumptions, based on processor utilization. This may lower average power 

consumption (in conjunction with OS support).

• Intel

 VT) — A set of hardware 

enhancements to Intel server and client platforms that can improve virtualization 

solutions. Intel VT will provide a foundation for widely-deployed virtualization 

solutions and enables more robust hardware assisted virtualization solutions. More 

information can be found at: http://www.intel.com/technology/virtualization/ 

• Intel

 TXT)— Intel

®

 Trusted Execution 

Technology (Intel

®

 TXT) is a security technology by Intel and requires for operation 

a computer system with Intel

®

 Virtualization Technology, a Intel Trusted Execution 

Technology-enabled Intel processor, chipset, BIOS, Authenticated Code Modules, 

and an Intel or other Intel Trusted Execution Technology compatible measured 

virtual machine monitor. In addition, Intel Trusted Execution Technology requires 

the system to contain a TPMv1.2 as defined by the Trusted Computing Group and 

specific software for some uses.

• Platform Environment Control Interface (PECI) — A proprietary one-wire bus 

interface that provides a communication channel between the processor and 

chipset components to external monitoring devices.
