I2C is a two-wire communications bus/protocol developed by NXP. SMBus is a subset of the I2C bus/protocol and was developed by intel . Implementations of the I2C bus/protocol may require licenses from various entities, including NXP Semiconductors intel Anti-Theft Technology ( intel AT): No system can provide absolute security under all conditions.

5 Requires an enabled Chipset , BIOS, firmware and software and a subscription with a capable Service Provider. Consult your System manufacturer and Service Provider for availability and functionality. intel assumes no liability for lost or stolen data and/or systems or any other damages resulting thereof. For more information, visit http://. intel High Definition Audio ( intel HD Audio): Requires an intel HD Audio enabled system. Consult your PC manufacturer for more information. Sound quality will depend on equipment and actual implementation. For more information about intel HD Audio, refer to intel Trusted Execution Technology ( intel TXT): No computer system can provide absolute security under all conditions.

6 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 , as defined by the Trusted Computing Group and specific software for some uses. For more information, see intel Active Management Technology ( intel AMT) requires activation and a system with a corporate network connection, an intel AMT-enabled Chipset , network hardware and software. For notebooks, intel AMT may be unavailable or limited over a host OS-based VPN, when connecting wirelessly, on battery power, sleeping, hibernating or powered off.
