This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment to an outlet on a circuit other than the one to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications to the equipment not expressly approved by Intel Corporation could void the
user’s authority to operate the equipment.
Tested to comply with FCC standards for home or office use.
Canadian Department of Communications Compliance Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus set
out in the Radio Interference Regulations of the Canadian Department of Communications.
Le présent appareil numerique német pas de bruits radioélectriques dépassant les limites applicables aux
appareils numériques de la classe B prescrites dans le Réglement sur le broullage radioélectrique édicté par

Intel Q33 Graphics Subsystem
The Intel Q33 Express Chipset contains two separate, mutually exclusive graphics
options. Either the integrated Intel®Graphics Media Accelerator 3100 (Intel®
GMA 3100) graphics controller is used or a PCI Express x16 add-in card can be used.
When a PCI Express x16 add-in card is installed, the Intel GMA 3100 graphics
controller is disabled.
Intel®GMA 3100 Graphics Controller
The Intel GMA 3100 graphics controller features the following:
•400 MHz core frequency
•High quality texture engine:
⎯DX9.0c* and OpenGL* 1.4 compliant
⎯Hardware Pixel Shader 2.0
⎯Vertex Shader Model 2.0
•3D Graphics Rendering enhancements:
⎯1.6 dual texture GigaPixel/s maximum fill rate
⎯16-bit and 32-bit color
⎯Vertex cache
•Video
⎯Software DVD at 30 fps full screen

•Display
⎯Up to 2048 x 1536 at 75 Hz refresh (QXGA)
⎯DDC2B compliant interface with Advanced Digital Display 2 card or Media
Expansion Card (ADD2/MEC), support for TV-out/TV-in and DVI digital display
connections
NOTE
A minimum of 512 MB of system memory is required in order for the Intel GMA 3100
graphics controller to operate properly.

Legacy Input/Output (I/O) Controller
The I/O controller features the following:
•One serial port interface via an onboard header
•Low pin count (LPC) interface
•Serial IRQ interface compatible with serialized IRQ support for PCI systems
•Intelligent power management, including a programmable wake up event interface
•PCI power management support
LAN Subsystem
The LAN subsystem includes:
•Intel ICH9
•Intel 82566DM Gigabit (10/100/1000 Mb/s) Ethernet LAN controller
•RJ-45 LAN connector with integrated LAN status LEDs
The subsystem also features:
•CSMA/CD protocol engine
•LAN connect interface between ICH9 and the LAN controller
•PCI bus power management

Desktop Board Features
19
LAN Status LEDs
Two LEDs are built into the RJ-45 LAN connector located on the back panel (see
Figure 2). These LEDs indicate the status of the LAN.
Figure 2. LAN Status LEDs
Table 3 describes the LED states when the board is powered up and the LAN
subsystem is operating.
Table 3. LAN Status LEDs
LED LED Color LED State Indicates
A Off LAN link is not established Green
On LAN link is established
Blinking LAN activity is occurring
N/A Off 10 Mb/s data rate
Green On 100 Mb/s data rate
B
Yellow On 1000 Mb/s data rate
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.

Intel Desktop Board DQ33HS Product Guide
20
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.
