8.15.4 Function 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.
