Dell R210 manual System Management Bus SMBus, Intel Anti-Theft Technology, Function Disable

Dell

8.15.4Function Disable

The Ibex Peak provides the ability to disable the following integrated functions: LAN, USB, LPC, Intel HD Audio, SATA, PCI Express or SMBus. Once disabled, these functions no longer decode I/O, memory, or PCI configuration space. Also, no interrupts or power management events are generated from the disabled functions.

Intruder Detect. The Ibex Peak provides an input signal (INTRUDER#) that can be attached to a switch that is activated by the system case being opened. The Ibex Peak can be programmed to generate an SMI# or TCO interrupt due to an active INTRUDER# signal.

8.16 System Management Bus (SMBus 2.0)

The Ibex Peak contains an SMBus Host interface that allows the processor to communicate with SMBus slaves. This interface is compatible with most I2C devices. Special I2C commands are implemented.

The Ibex Peak’s SMBus host controller provides a mechanism for the processor to initiate communications with SMBus peripherals (slaves). Also, the Ibex Peak supports slave functionality, including the Host Notify protocol. Hence, the host controller supports eight command protocols of the SMBus interface (see System Management Bus

(SMBus) Specification, Version 2.0): Quick Command, Send Byte, Receive Byte, Write Byte/Word, Read Byte/Word, Process Call, Block Read/Write, and Host Notify.

Ibex Peak’s SMBus also implements hardware-based Packet Error Checking for data robustness and the Address Resolution Protocol (ARP) to dynamically provide address to all SMBus devices.

8.17 Intel Anti-Theft Technology

The Ibex Peak introduces a new hardware-based security technology which encrypts data stored on any SATA compliant HDD in AHCI Mode. This feature gives the end-user the ability to restrict access to HDD data by unknown parties. Intel Anti-Theft Technology can be used alone or can be combined with software encryption applications to add protection against data theft.

Intel Anti-Theft Technology functionality requires a correctly configured system, including an appropriate processor, Intel Management Engine firmware, and system BIOS support.

8.18 Intel Virtualization Technology for Directed I/O

The Ibex Peak provides hardware support for implementation of Intel Virtualization Technology with Directed I/O (Intel VT-d). Intel VT-d Technology consists of technology components that support the virtualization of platforms based on Intel Architecture Processors. Intel VT-d Technology enables multiple operating systems and applications to run in independent partitions. A partition behaves like a virtual machine (VM) and provides isolation and protection across partitions. Each partition is allocated its own subset of host physical memory.
