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, you can 
also configure Supero Doctor to provide you with warnings when the system 
temperature, CPU temperatures, voltages and fan speeds go beyond predefined 
thresholds.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specifica-
tion 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. 
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 Windows XP, Windows Vista and Windows 
2008 Operating Systems. 
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start to blink 
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.
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.
This motherboard accommodates 24-pin ATX power supplies. Although most 
power supplies generally meet the specifications required by the CPU, some are 
inadequate. In addition, the 12V 8-pin power connector located at JPW2 is also 
required to ensure adequate power supply to the system. Also your power supply 
must supply 1.5A for the Ethernet ports.
Warning! 1. To prevent damage to the power supply or motherboard, 
please use a power supply that contains a 24-pin and a 8-pin power con-
nectors. Be sure to connect these connectors to the 24-pin (JPW1) and the
