Hi-Speed USB 2.0 Support

The Desktop Board supports up to eight USB 2.0 ports (four ports routed to the back panel and four ports routed to two internal headers) via the ICH7. USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.

USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0.

Desktop Board Features

Enhanced IDE Interface

The board’s IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. The interface supports:

• Up to two IDE devices (such as hard drives)

• ATAPI-style devices (such as CD-ROM drives)

• Older PIO Mode devices

• Ultra DMA-33 and ATA-66/100 protocols

Serial ATA

The Desktop Board supports two Serial ATA channels (3.0 Gb/s) via ICH7, connecting one device per channel.

Expandability

For system expansion, the Desktop Board provides two PCI bus connectors.

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash component.

The BIOS can be updated by following the instructions on page

Serial ATA and IDE Auto Configuration

If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the auto-configuration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.

PCI* and Auto Configuration

If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card.

53 in Chapter 3.

Intel Desktop Board DG31GL Product Guide

Security Passwords

The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup and for booting the computer, with the following restrictions:

• The supervisor password gives unrestricted access to view and change all Setup

options. If only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives the user restricted access to Setup.

• If both the supervisor and user passwords are set, you must enter either the

supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered.

• Setting a user password restricts who can boot the computer. The password

prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

• Monitoring of power supply voltages to detect levels above and below acceptable

values

• Fan speed controllers and sensors integrated into the legacy I/O controller

• Thermal sensors in the processor, GMCH, and ICH7, plus an onboard remote

sensor

• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust

fan speed or switch the fans off as needed

Power Management

Power management is implemented at several levels, including:

• Software support through the Advanced Configuration and Power Interface (ACPI)

• Hardware support:

⎯ Power connectors ⎯ Fan headers ⎯ LAN wake capabilities ⎯ Instantly Available PC technology (Suspend to RAM) ⎯ +5 V standby power indicator LED ⎯ Wake from USB ⎯ Power Management Event signal (PME#) wakeup support

• ENERGY STAR capable

Desktop Board Features

ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Desktop Board requires an operating system that provides full ACPI support.

Hardware Support

Power Connectors

ATX12V-compliant power supplies can turn off the computer power through system control. When an ACPI-enabled computer receives the correct command, the power supply removes all non-standby voltages.

When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (either on or off). The computer’s response can be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.

The Desktop Board has two power connectors. See location of the power connectors.

Figure 22 on page 44 for the

Fan Headers

The function/operation of the fans is as follows:

• The fans are on when the computer is in the ACPI S0 state.

• The fans are off when the computer is in the ACPI S3, S4, or S5 state.

• Each fan header is wired to a tachometer input of the hardware monitoring and

control device.

• All fan headers support closed-loop fan control that can adjust the fan speed or

switch the fan on or off as needed.

• All fan headers have a +12 V DC connection. The Desktop Board has a 4-pin processor fan header and a 3-pin chassis fan header.

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply.

LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer.

Intel Desktop Board DG31GL Product Guide

Instantly Available PC Technology

CAUTIONS

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

Power supplies used with this Desktop Board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Desktop Board may lose register settings stored in memory.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If the computer has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. When signaled by a wake-up device or event, the computer quickly returns to its last known awake state.

The Desktop Board supports the PCI Bus Power Management Interface Specification. Add-in cards that support this specification can participate in power management and can be used to wake the computer.

+5 V Standby Power Indicator LED

CAUTION

If the AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices.

The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is standby power still present on the board even when the computer appears to be off. For example, when this LED is lit, standby power is still present at the memory module sockets and the PCI bus connectors.

Figure 3. Location of the Standby Power Indicator

For information on standby current requirements for the Desktop Board, refer to the Technical Product Specification by going to

http://support.intel.com/support/motherboards/desktop/, finding the product, and

clicking on the Technical Documents tab.

Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

USB bus activity wakes the computer from an ACPI S3 state.

Intel Desktop Board DG31GL Product Guide

PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state.

ENERGY STAR* Capable

In 2007, the US Department of Energy and the US Environmental Protection Agency revised the ENERGY STAR requirements. Intel worked directly with these two governmental agencies to define the new requirements. Currently Intel Desktop Boards are capable of meeting the new ENERGY STAR requirements depending upon system configuration.

Go to the following link for information and recommendations concerning the new ENERGY STAR requirements:

http://www.intel.com/go/EnergyStar

Speaker

A speaker is mounted on the Desktop Board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST).

Battery

A battery on the Desktop Board keeps the values in CMOS RAM and the clock current when the computer is turned off. Go to page battery.

http://support.intel.com/support/motherboards/desktop.

Navigate to the DG31GL page, click “[view] Latest BIOS updates,” and select the ISO Image BIOS Update or Iflash BIOS Update utility file.

Updating the BIOS with the ISO Image BIOS Update File

The ISO Image BIOS update allows for the update of an Intel® Desktop Board BIOS to the latest production release regardless of the operating system installed on the computer's hard drive and without the need to remove the BIOS configuration jumper. It requires a blank CD-R, a read/writeable CD drive, and software capable of uncompressing and writing the ISO image file to CD.

The image uses ISOLINUX* bootloader and automatically launches a script to upgrade the BIOS via the Iflash utility.

Updating the BIOS

CAUTION

Do not interrupt the process or the system may not function properly.

Follow these instructions to upgrade the BIOS using the ISO Image BIOS file:

1. Download the ISO Image BIOS file.

2. Using software capable of uncompressing and writing an ISO image file to CD, burn

the data to a blank CD.

NOTE

Copying the ISO Image BIOS file to CD will not work. The completed CD should contain multiple files and a directory.

3. Insert the CD that was created in the CD-ROM drive of the computer to be

upgraded and boot the system.

4. When the "Press ENTER to continue booting from CD-ROM" prompt appears, press

the Enter key. The system will boot from the hard drive if no key is pressed within 15 seconds.

5. At the "Welcome to the Intel Desktop Board BIOS Upgrade CD-ROM" page, press

any key to confirm the BIOS upgrade operation.

6. Wait for the BIOS upgrade process to complete.

CAUTION

DO NOT POWER DOWN YOUR COMPUTER before the update is complete. The update may take up to 5 minutes.

Updating the BIOS with the Iflash Memory Update Utility

With the Iflash Memory update utility you can update the system BIOS from a bootable CD-ROM, bootable USB flash drive, or other bootable USB media. The utility available on the Intel World Wide Web site provides a simple method for creating a bootable CD-ROM that will automatically update your BIOS. The Iflash BIOS update files can also be extracted locally to your hard drive and copied to a bootable USB flash drive or other bootable USB media.

The Iflash Memory update utility allows you to:

• Update the BIOS in flash memory

• Update the language section of the BIOS

NOTE

Review the instructions distributed with the update utility before attempting a BIOS update.

Intel Desktop Board DG31GL Product Guide

CAUTION

Do not interrupt the process or the system may not function properly.

1. Uncompress the BIOS update file and copy the .BIO file, IFLASH.EXE, and .ITK file

(optional) to a bootable USB flash drive or other bootable USB media.

2. Configure the BIOS or use the F10 option during POST to boot to the USB device.

3. Manually run the IFLASH.EXE file from the USB device and manually update the

BIOS.

Recovering the BIOS

It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. Due to BIOS size and recovery requirements, a CD-R with the .BIO file in the root directory will be required.

Intel Desktop Board DG31GL Product Guide

Lead-free 2LI/Pb-free 2LI Board

The electronics industry is transitioning to European Union (EU) Restriction of Hazardous Substances (RoHS)-compliant products. The RoHS legislation restricts the use of six materials. One of these restricted materials is lead. Lead is the most common and problematic of the RoHS restricted materials.

There are exemptions in RoHS that allow the use of lead in some very limited locations in electronic products. Maximum lead concentration values have been established for RoHS-compliant electronic products that allow up to 1000 ppm of lead.

Lead-free/Pb-free is a nickname that is often used (or misused) for RoHS-compliant products. In this case, the term "Lead-free/Pb-free" means that lead has been removed where required by the RoHS legislation but still may exist as an impurity below 1000 ppm.

The term "Lead-free 2LI/Pb-free 2LI" means lead-free second level interconnect (2LI). The balls, leads, or pads used to connect the component to a printed circuit board are lead-free, but the first level interconnect (FLI) is not lead-free. The use of lead in the FLI is acceptable because of the RoHS "flip chip" or "die bump" interconnect exemption.

Desktop Board DG31GL is a lead-free second level interconnect product. shows the lead-free second level interconnect marks as they appear on the board and accompanying collateral. These marks are based on JEDEC standard J-STD-609, “Marking and Labeling of Components, PCBs and PCBAs to Identify Lead, Lead Free and Other Attributes.”

For more information concerning Intel’s lead-free initiatives, refer to

http://www.intel.com/technology/silicon/leadfree.htm.

Table 14

Table 14. Lead-Free Second Level Interconnect Marks

Description Mark

This symbol is used to identify electrical and electronic assemblies and components in which the Pb concentration level in the Desktop Board substrate and the solder connections from the board to the components (second-level interconnect) is not greater than 0.1% by weight (1000 ppm).

Regulatory Compliance

Restriction of Hazardous Substances (RoHS)

EU RoHS

EU RoHS Directive 2002/95/EC restricts the use of the following six materials in various types of electronic and electrical equipment:

• Lead

• Mercury

• Cadmium

• Hexavalent chromium

• Polybrominated biphenyls (PBB)

• Polybrominated diphenyl ether (PBDE)

The maximum concentrations allowed are 0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100 ppm) by weight of homogeneous material.

Desktop Board DG31GL complies with these restrictions.

Intel Desktop Board DG31GL Product Guide

China RoHS

“China RoHS” is the term used by industry generally to describe legislation implemented by the Ministry of Information Industry (MII) in the People's Republic of China for the control of pollution by electronic information products (EIP). The official title of the China RoHS regulation is “Management Methods for Controlling Pollution by Electronic Information Products.”

China RoHS bans the same substances and has the same limits as EU RoHS. However, the China RoHS regulation requires specific product marking and a selfdeclaration of the controlled substances contained in each product.

Desktop Board DG31GL is a China RoHS-compliant product. The required China RoHS mark indicates the product’s Environmental Friendly Usage

Period (EFUP). The EFUP is defined as the number of years for which listed controlled substances will not leak or chemically deteriorate while in the product. The EFUP for Intel Desktop Boards has been determined to be 10 years.

The EFUP for Desktop Board DG31GL is shown in

Table 15.

Table 15. China RoHS Environmentally Friendly Use Period Mark

Description Mark

This is an example of the symbol used on Intel Desktop Boards and associated collateral. The color of the mark may vary depending upon the application. The Environmental Friendly Usage Period (EFUP) for Intel Desktop Boards has been determined to be 10 years.

Regulatory Compliance

The China MII stipulates that a material Self Declaration Table (SDT) must be included in a product’s user documentation. The SDT for Desktop Board DG31GL is shown in Figure 25.
