Introduction
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera-
ture. When this temperature is exceeded, both the overheat fan and the
warning LED are triggered.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager
(optional). LDCM is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf-
ficient hard drive space for saving the data, you can be alerted of the
potential problem.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.4V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.

ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft-
ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele-
phones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win-
dows 2000 and Windows 2003.
