SMART LAN (LAN Cable Diagnostic Function)
This motherboard incorporates cable diagnostic feature designed to detect the status of the attached LAN
cable.  This feature will detect cabling issue and report the approximate distance to the fault or short.
Refer to the following information for diagnosing your LAN cable:
When No LAN Cable Is Attached...
If no LAN cable is attached to the motherboard, the Status fields of all four pairs of wires will show
Open and the Length fields show 0m,  as shown in the figure above.
When LAN Cable Is Functioning Normally...
If no cable problem is detected on the LAN cable connected to a Gigabit hub or a 10/100 Mbps hub,
the following message will appear:

Note: The Gigabit hub will only operate at a speed of 10/100Mbps in MS-DOS mode; it will operate
at a normal speed of 10/100/1000 Mbps in Windows mode or when the LAN Boot ROM is activated.
When a Cable Problem Occurs...
If a cable problem occurs on a specified pair of wires, the Status field will show Short and
thenlength shown will be the approximate distance to the fault or short.
Example: Pair1-2 Status = Short / Length  =  2m
Explanation: A fault or short might occur at about 2m on Pair 1-2.
Note: Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, so their Status fields will
show Open, and the length shown is the approximate length of the attached LAN cable.

2-6 Power Management Setup
ACPI Suspend Type
Specifies the ACPI sleep state when the system enters suspend.
S1(POS)Enables the system to enter the ACPI S1 (Power on Suspend) sleep state(default).
In S1 sleep state, the system appears suspended and stays in a low power
mode. The system can be resumed at any time.
S3(STR)Enables the system to enter the ACPI S3 (Suspend to RAM) sleep state.
In S3 sleep state, the system appears to be off and consumes less power than
in the S1 state. When signaled by a wake-up device or event, the system
resumes to its working state exactly where it was left off.
Soft-Off by PWR-BTTN
Configures the way to turn off the computer in MS-DOS mode using the power button.
Instant-Off Press the power button and then the system will be turned off instantly. (Default)
Delay 4 Sec.Press and hold the power button for 4 seconds to turn off the system. If the power
button is pressed for less than 4 seconds, the system will enter suspend mode.
PME Event Wake Up
Allows the system to be awakened from an ACPI sleep state by a wake-up signal from a PCI or
PCIe device. Note: To use this function, you need an ATX power supply providing at least 1A on
the 5VSB lead. (Default: Enabled)
Power On by Ring
Allows the system to be awakened from an ACPI sleep state by a wake-up signal from a modem
that supports wake-up function. (Default: Enabled)
(Note) Supported on Windows
® Vista® operating system only.

default values. (Default: Disabled)
(Note) This item appears only if you install a CPU that supports this feature.Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory
and reduce the useful life of these components.  This page is for advanced users only and
we recommend you not to alter the default settings to prevent system instability or other
unexpected results. (Inadequately altering the settings may result in systems failure to
boot. If this occurs, clear the CMOS values and reset the board to default values.)
