1-5 ACPI Features

ACPIstandsforAdvancedCongurationandPowerInterface.TheACPIspecica-

tion denes 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conguration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specications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

8-pin (JPW2) power connectors on the motherboard. Failure in doing so will

void the manufacturer warranty on your power supply and motherboard.

2. To provide adequate power to SATA devices, please connect the SATA

DOM PWR connector (JWF1) to the power supply.
