Desktop Board Features

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 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.

Serial ATA

The Desktop Board supports three Serial ATA channels (3.0 Gb/s) via ICH7, connecting

one device per channel.

Expandability

For system expansion, the Desktop Board includes one PCI bus connector.

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 53 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* 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.

Intel Desktop Board DG41MJ 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 46.

Hardware Management Features

The hardware management features of Intel Desktop Board DG41MJ 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

Hardware Monitoring and Fan Speed Control

Features of the board’s hardware monitoring and fan speed control include:

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

values.

• Smart fan control provided by the legacy I/O controller, delivering acoustically-

optimized thermal management. Fan speed controllers and sensors are integrated

into the legacy I/O controller.

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

speed according to thermal conditions.

• Two thermal sensors (processor and a remote thermal sensor).

Desktop Board Features

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#) wake-up support

⎯ Wake from PS/2 devices

⎯ Wake from serial port

• 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.

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 21 on page 44 for the

location of the power connectors.

Intel Desktop Board DG41MJ Product Guide

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.

• The processor fan header is wired to a fan tachometer input. The chassis fan

header has an independent tachometer input to the hardware monitoring and fan

control device.

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

according to thermal conditions.

• 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.

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-to-

RAM) 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.

Desktop Board Features

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 connector.

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® 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 Intel Desktop Board DG41MJ page on the Intel World Wide Web site at

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

Navigate to the Intel Desktop Board DG41MJ page, click “Latest BIOS,” 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.

CAUTION

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

Updating the BIOS

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.

CAUTION

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

Intel Desktop Board DG41MJ Product Guide

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.
