Acpi Features - Supermicro X7DA3 User Manual

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 defi ne an overheat temperature. When the
CPU temperature reaches this overheat threshold, both the overheat fan and the
warning LED are triggered.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS en-
vironment 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 insuffi cient hard drive space for saving the data, you
can be alerted of the potential problem. You can also confi gure Supero Doctor to
provide you with warnings when the system temperature goes beyond a pre-de-
fi ned range.

ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible 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 confi guration 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
