1.5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines
a flexible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system including its hardware, operating system
and application software. This enables the system to automatically turn on and off peripherals
such as network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also 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
appropriate Windows operating systems. For detailed information on OS support, please refer

1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates and in
areas where noisy power transmission is present.
1.7 Advanced Power Management
The following new advanced power management features are supported by the motherboard.
Management Engine (ME)
The Management Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides
Server Platform Services (SPS) to your system. The services provided by SPS are different
from those provided by the ME on client platforms.
