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 congure Supero Doctor to provide you with warnings when the system
temperature, CPU temperatures, voltages and fan speeds go beyond predened
thresholds.
1-5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes a 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.
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 conguration 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 specications 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! Please use a power supply that contains a 24-pin and an 8-pin
or a 4-pin power connector. Be sure to connect these connectors to the 24-
pin (JPW1) and the 8-pin (JPW2) power connectors on the motherboard.
Note: The JPW2 power connector on the motherboard also supports
one 4-pin connector.
