1-5 Acpi Features - Supermicro Supero X6DAL-B2 User Manual

TM2/CPU VRM Overheat
When the CPU reaches 70
down and CPU Voltage will decrease to reduce CPU power consumption
and CPU VRM heat dissipation.
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 the temperature goes beyond the predefined threshold, the
warning LED is triggered and the fans will speed up.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
120W current and auto-sense voltage IDs ranging from .8375V to 1.6V.
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 the 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.
verages the Plug and Play BIOS data structures, while providing a proces-
sor architecture-independent implementation that is compatible with the Win-
dows 2000, Windows XP and Windows 2003 operating systems.
