No computer system can provide absolute security under all conditions. Intel
®
Trusted Execution Technology (Intel
®
TXT) requires a computer system with Intel
®
Virtualization Technology, an Intel TXT-enabled processor, chipset, BIOS,
Authenticated Code Modules and an Intel TXT-compatible measured launched environment (MLE). The MLE could consist of a virtual machine monitor, an OS or an application. In addition, Intel TXT requires the system to contain a TPM v1.2,
asdenedbytheTrustedComputingGroupandspecicsoftwareforsomeuses.Formoreinformation,seehttp://www.intel.com/technology/security.

Intel
®
Active Management Technology requires the computer system to have an Intel
®
AMT-enabled chipset, network hardware and software, as well as connection with a power source and a corporate network connection. Setup requires
congurationbythepurchaserandmayrequirescriptingwiththemanagementconsoleorfurtherintegrationintoexistingsecurityframeworkstoenablecertainfunctionality.Itmayalsorequiremodicationsorimplementationofnewbusiness
processes.Formoreinformation,seewww.intel.com/technology/platform-technology/intel-amt/.

Core
™
2 Quad processor, shared L2 cache refers to 6 MB of L2 cache per core pair.

Intel
®
Virtualization Technology requires a computer system with an enabled Intel

processor,BIOS,virtualmachinemonitor(VMM)and,forsomeuses,certainplatformsoftwareenabledforit.Functionality,performanceorother
benetswillvarydependingonhardwareandsoftwarecongurationsandmayrequireaBIOSupdate.Softwareapplicationsmaynotbecompatiblewithalloperatingsystems.Pleasecheckwithyourapplicationvendor.
5
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel
®
64 architecture. Processors will not operate (including 32-bit operation)
withoutanIntel64architecture-enabledBIOS.Performancewillvarydependingonyourhardwareandsoftwarecongurations.Consultwithyoursystemvendorformoreinformation.
6
Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
