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 ICH9. 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.
19
Intel Desktop Board DQ33HS Product Guide
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 ICH9, connecting
one device per channel. One channel is configured as an eSATA channel.
Expandability
For system expansion, the Desktop Board provides the following expansion slots:
• Two PCI Express x1 connectors
• One PCI Express x16 connector
• One PCI bus connector
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.
The BIOS can be updated by following the instructions on page 63 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.
20
Desktop Board Features
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 56.
Trusted Platform Module (TPM)
The TPM 1.2 device is designed to enhance platform security above and beyond the
capabilities of today’s software by providing a protected space for key operations and
other security critical tasks. Using both hardware and software, the TPM protects
encryption and signature keys at their most vulnerable stages—operations when the
keys are being used unencrypted in plain-text form. The TPM is specifically designed
to shield unencrypted keys and platform authentication information from softwarebased attacks.
For information about enabling and activating the TPM, refer to the Trusted Platform
Module (TPM) Quick Reference Guide.
Hardware Management Features
The hardware management features of Desktop Board DQ33HS 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
21
Intel Desktop Board DQ33HS Product Guide
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
• Intel Quiet System Technology fan speed control, delivering acoustically-optimized
thermal management
NOTE
Memory must be installed in the Channel A, DIMM 0 socket to enable Intel
Quiet System Technology.
• Fan speed controllers and sensors integrated into ICH9
• Thermal sensors in the processor, GMCH, and ICH9, plus an onboard remote

The minimum thermal reporting threshold for the GMCH is 66 °C. The GMCH
thermal sensor will display 66 °C until its temperature rises above this point.
• 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 Figure 22 on
page 47 for the location of the cha
ssis intrusion header.

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 Figure 25 on page 53 for the
location of the power co
nnectors.
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
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 wake capabilities enable remote wake-up of the computer through a network.
The LAN subsystem PCI bus network adapter monitors network traffic at the Media
Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem
asserts a wake-up signal that powers up the computer. Depending on the LAN
implementation, the board supports LAN wake capabilities with ACPI in the following
ways:
• The PCI Express WAKE# signal
• The PCI bus PME# signal for PCI 2.3 compliant LAN designs
• By Ping
• Magic Packet
• The onboard LAN subsystem
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.

Desktop Board Features
+5 V Standby Power Indicator
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 (green LED), 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 indicator 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 S1 or S3 state.
PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S1, 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 S1, S3, S4, or S5 state.
