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.

1-5 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 NT 5.0.
