Chapter 1: 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 temperature. When this
temperature exceeds the predefined temperature threshold, both overheat fan and
the warning LED will be activated.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notify the user of certain system events. For example, if the system is running
low on virtual memory and there is insufficient hard drive space for saving the
data, you can be alerted of the potential problem. You can also configure Supero
Doctor to provide you with warnings when the system temperature goes beyond
a pre-defined range.

ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specifi-
cation defines a flexible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including its
hardware, operating system and application software. 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, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for configuration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with Windows 2000, Windows XP and Windows
2003 Server.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button to make the system enter a SoftOff state. The monitor will be
suspended and the hard drive will spin down. Pressing the power button again will
cause the whole system to wake-up. During the SoftOff state, the ATX power
