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.

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 four Serial ATA channels (3.0 Gb/s) via ICH7, connecting one device per channel.

Desktop Board Features

Expandability

For system expansion, the Desktop Board provides the following expansion slots:

• One PCI Express x1 connector

• One PCI Express x16 connector

• Two PCI bus connectors

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI Express 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

59 in Chapter 3.

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 PCI Express* Auto Configuration

If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express 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/PCI Express add-in card.

Intel Desktop Board DG31PR 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.

For instructions on resetting the password, see

Clearing Passwords on page 53.

Hardware Management Features

The hardware management features of Desktop Board DG31PR enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following:

• Fan speed monitoring and control

• Thermal and voltage monitoring

• Chassis intrusion detection

Desktop Board Features

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

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the Desktop Board. See the location of the c

hassis intrusion header.

Figure 21 for

Power Management Features

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

⎯ WAKE# signal wake-up support

• ENERGY STAR capable

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.

Intel Desktop Board DG31PR Product Guide

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 co

nnectors.

Figure 24 on page 51 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 two 3-pin chassis fan

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.

Desktop Board Features

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.

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.

Desktop Board Features

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.

WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S2, S3, S4, or S5 state.

ENERGY STAR* Capable

3 Updating the BIOS

The BIOS Setup program can be used to view and change the BIOS settings for the computer. You can access the BIOS Setup program by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins.

This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update utility or the Iflash Memory Update utility, and how to recover the BIOS if an update fails.

Updating the BIOS with the Intel® Express BIOS Update Utility

With the Intel Express BIOS Update utility you can update the system BIOS while in the Windows environment. The BIOS file is included in an automated update utility that combines the functionality of the Intel of use of Windows-based installation wizards.

Flash Memory Update Utility and the ease

To update the BIOS with the Intel Express BIOS Update utility:

1. Go to the Intel World Wide Web site:

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

2. Navigate to the DG31PR page, click “[view] Latest BIOS updates,” and select the

Express BIOS Update utility file.

3. Download the file to your hard drive. (You can also save this file to a removable

USB device. This is useful if you are updating the BIOS for multiple identical

systems.)

4. Close all other applications. This step is required. Your system will be rebooted at

the last Express BIOS Update window.

5. Double-click the executable file from the location on your hard drive where it was

saved. This runs the update program.

6. Follow the instructions provided in the dialog boxes to complete the BIOS update.

Intel Desktop Board DG31PR Product Guide

Updating the BIOS with the ISO Image BIOS Update File or the Iflash Memory Update Utility

You can use the information in this section to update the BIOS using either the Iflash Memory Update Utility or the ISO Image BIOS update file.

Obtaining the BIOS Update File

You can update to a new version of the BIOS by using the ISO Image BIOS update file (recommended), or Iflash BIOS update file.

The ISO Image BIOS update file is a standardized image of a bootable CD-ROM that can be used to create a bootable CD that will update the BIOS.

The Iflash BIOS update file is a compressed file that contains the files you need to update the BIOS. The Iflash BIOS update file contains:

• New BIOS file

• Intel

• Intel Flash Memory Update Utility

Integrator Toolkit Configuration File (optional)

You can obtain either of these files through your computer supplier or by navigating to the Desktop Board DG31PR page on the Intel World Wide Web site at:

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

Navigate to the DG31PR 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 DG31PR 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.
