GA-M720-US3 Motherboard - 44 - SMART LAN (LAN Cable Diagnostic Function) CMOS Setup Utility-Copyright (C) 1984-2008 Award Software SMART LAN Item Help Menu Level. Start detecting at Port..... Part1-2 Status = Open / Length = 0m Part3-6 Status = Open / Length = 0m Part4-5 Status = Open / Length = 0m Part7-8 Status = Open / Length = 0m ....: Move Enter: Select +/-/PU/PD: Value F10: Save ESC: Exit F1: General Help F5: Previous Values F6: Fail-Safe Defaults F7: Optimized Defaults 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. Link Detected Displays transmission speed Cable Length Displays the approximate length of the attached LAN cable. Start detecting at Port..... Link Detected --> 100Mbps Cable Length= 30m 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: Part1-2 Status = Short / Length = 2m Explanation: A fault or short might occur at about 2m on Part 1-2. Note: Part 4-5 and Part 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. 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: - 45 - BIOS Setup Onboard LAN Boot ROM Allows you to decide whether to activate the boot ROM integrated with the onboard LAN chip. (Default: Disabled) Onboard Serial Port Enables or disables the first serial port and specifies its base I/O address and corresponding interrupt. Options are: Auto, 2F8/IRQ3, 3F8/IRQ4(default), 3E8/IRQ4, 2E8/IRQ3, Disabled. On-Chip USB Configures the integrated USB controller. V1.1+V2.0 Enables the integrated USB 1.1 and USB 2.0 controllers. (Default) V1.1 Enables only the integrated USB 1.1 controller. Disabled Disables the integrated USB 1.1 and USB 2.0 controllers. Disabled will turn off all of the USB functionalities below. USB Memory Type Specifies the type of memory allocated for USB devices. Options are: SHADOW (default), Base Memory (640K). USB Keyboard Support Allows USB keyboard to be used in MS-DOS. (Default: Disabled) USB Mouse Support Allows USB mouse to be used in MS-DOS. (Default: Disabled) Legacy USB storage detect Determines whether to detect USB storage devices, including USB flash drives and USB hard drives during the POST. (Default: Enabled) GA-M720-US3 Motherboard - 46 - 2-7 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. 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 (default). 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 Power button 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 signa...
