ICH8 Family Datasheet
Enhanced Power Management
The ICH8’s power management functions include enhanced clock control and various
low-power (suspend) states (e.g., Suspend-to-RAM and Suspend-to-Disk). A hardware-
based thermal management circuit permits software-independent entrance to low-
power states. The ICH8 contains full support for the Advanced Configuration and Power
Interface (ACPI) Specification, Revision 2.0.
Intel
ICH8DH implements Intel Quick Resume Technology (QRT) to give the PC a Consumer
Electronics device-like feel. Intel QRT provides the capability to design a PC with a
single power button that reliably and instantly (user's perception) turns the PC On and
Off. When the system is On and the user presses the power button, the display
instantly goes dark, sound is muted, and there is no response to keyboard/mouse
commands (except for keyboard power button). When the system is Off and the user
presses the power button, picture and sound quickly return, and the keyboard/mouse
return to normal functionality, allowing user input.

and ICH8M-E
Intel Active Management Technology is the next generation of client manageability via
the wired network. Intel AMT is a set of advanced manageability features developed as
a direct result of IT customer feedback gained through Intel market research. With the
new implementation of System Defense in ICH8, the advanced manageability feature
set of Intel AMT is further enhanced.
Manageability
In addition to Intel AMT the ICH8 integrates several functions designed to manage the
system and lower the total cost of ownership (TCO) of the system. These system
management functions are designed to report errors, diagnose the system, and recover
from system lockups without the aid of an external microcontroller.

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.
attached to a switch that is activated by the system case being opened. The ICH8
can be programmed to generate an SMI# or TCO interrupt due to an active
INTRUDER# signal.
Note: ASF functionality with the integrated ICH8 ASF controller requires a correctly
configured system, including an appropriate (G)MCH with ME, ME Firmware,
system BIOS support, and appropriate Platform LAN Connect Device.
