If an FCC declaration of conformity marking is present on the board, the following statement applies:
FCC Declaration of Conformity
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
For questions related to the EMC performance of this product, contact:
Intel Corporation, 5200 N.E. Elam Young Parkway, Hillsboro, OR 97124
1-800-628-8686
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
le ministére des Communications du Canada.

Digital Video Interface (DVI)
The DVI port supports only DVI-D (digital only) displays. The maximum support
resolution is 1600 x 1200 at a 60 Hz refresh rate. The DVI port is compliant with the
DVI 1.0 specification.
Depending on the type of add-in card installed in the PCI Express x16 connector, the
DVI and VGA ports will behave as described in
Table 3.
Table 3. DVI/VGA Port Status

Audio Subsystem
The onboard audio subsystem consists of the following:
Intel
®
ICH9R I/O controller hub
IDT STAC9271D audio codec
Back panel audio connectors
Onboard audio headers:
Intel High Definition audio front panel audio header
HD audio link header
The audio subsystem supports the following features:
Dolby* Home Theater support
A signal-to-noise (S/N) ratio of 95 dB

Consumer Infrared (CIR) support
Low pin count (LPC) interface
One serial port interface via an onboard header
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 ICH9R
Intel 82566DC Gigabit (10/100/1000 Mb/s) Ethernet LAN controller
RJ-45 LAN connector with integrated status LEDs
The subsystem features:
CSMA/CD protocol engine
LAN connect interface between ICH9R and the LAN controller
PCI bus power management

http://support.intel.com/support/motherboards/desktop
RJ-45 LAN Connector 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.

Table 4 describes the LED states when the board is powered up and the LAN
subsystem is operating.

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 the ICH9R. 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
Desktop Board Features
19
Serial ATA
The Desktop Board supports six Serial ATA channels (3.0 Gb/s) via ICH9R, connecting
one device per channel. One channel is configured as an eSATA channel.
Serial ATA RAID
The ICH9R supports the following RAID (Redundant Array of Independent Drives)
levels:
RAID 0 - data striping
RAID 1 - data mirroring
RAID 0+1 (or RAID 10) - data striping and mirroring
RAID 5 - distributed parity
For information on configuring your system for RAID using Intel

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.

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.
