Intel Desktop Board DG33FB Product Guide

Hi-Speed USB 2.0 Support

The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to the back panel and six ports routed to three internal headers) via the ICH9DH. 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 ICH9DH, connecting one device per channel.

Expandability

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

• One PCI Express x16 connector

• Three PCI Express x1 connectors

• Three 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 device.

The BIOS can be updated by following the instructions on page

59 in Chapter 3.

Desktop Board Features

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.

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 DG33FB 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

Intel Desktop Board DG33FB Product Guide

Hardware Monitoring and Fan Speed Control

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

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.

Desktop Board Features

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.

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 one 4-pin 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.

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.

Wake from PS/2 Keyboard/Mouse

PS/2 keyboard/mouse activity wakes the computer from an ACPI S3 state.

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.
