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:
o
o
o
o

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.

18

Desktop Board Features

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

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.

19

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:
o

o

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.

21

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 Figure 24 on page 51 for the
location of the power connectors.

Fan Headers
The function/operation of the fans is as follows:
o
o
o
o
o

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
headers.

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.

22

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.

Replacing the Battery
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to +- 13 minutes/year at
25 oC with 3.3 VSB applied.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 26 on page 58 shows the location of the
battery.

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 & lt; F2 & gt; 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(R) 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(R) Flash Memory Update Utility and the ease
of use of Windows-based installation wizards.
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.

59

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:
o
o
o

New BIOS file
Intel(R) Integrator Toolkit Configuration File (optional)
Intel Flash Memory Update Utility

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(R) 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.

60

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:
o
o

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.

61

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.

Lead-Free Desktop Board
This Desktop Board is a European Union Restriction of Hazardous Substances (EU
RoHS Directive 2002/95/EC) compliant product. EU RoHS restricts the use of six
materials. One of the six restricted materials is lead.
Intel Desktop Board DG31PR is lead-free although certain discrete components used
on the board contain a small amount of lead which is necessary for component
performance and/or reliability. This Desktop Board is referred to as "Lead-free second
level interconnect." The board substrate and the solder connections from the board to
the components (second-level connections) are all lead-free.
China bans the same substances and has the same limits as EU RoHS; however it
requires different product marking and controlled substance information. The required
mark shows the Environmental Friendly Usage Period (EFUP). The EFUP is defined as
the number of years for which controlled listed substances will not leak or chemically
deteriorate while in the product.

Intel Desktop Board DG31PR Product Guide

Chassis and Component Certifications
Ensure that the chassis and certain components; such as the power supply, peripheral
drives, wiring, and cables; are components certified for the country or market where
used. Agency certification marks on the product are proof of certification. Typical
product certifications include:
In Europe
The CE marking signifies compliance with all applicable European requirements. If the
chassis and other components are not properly CE marked, a supplier's Declaration of
Conformity statement to the European EMC directive and Low Voltage directive (as
applicable), should be obtained. Additionally, other directives, such as the Radio and
Telecommunications Terminal Equipment (R & TTE) directive may also apply depending
on product features.
In the United States
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL,
CSA, or ETL signifies compliance with safety requirements. Wiring and cables must
also be UL listed or recognized and suitable for the intended use. The FCC Class B
logo for home or office use signifies compliance with electromagnetic interference
(EMI) requirements.
In Canada
A nationally recognized certification mark such as CSA or cUL signifies compliance with
safety requirements. The Industry Canada statement at the front of this product guide
demonstrates compliance with Canadian EMC regulations.
