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.

System Memory
NOTE
To be fully compliant with all applicable Intel®SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD)
data structure. If your memory modules do not support SPD, you will see a
notification to this effect on the screen at power up. The BIOS will attempt to
configure the memory controller for normal operation.
The Desktop Board supports the dual or single channel memory configurations defined
below:
•Two 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline Memory Module
(DIMM) connectors with gold-plated contacts
•Support for:
⎯Non-ECC, 1.8 V, DDR2 800/667 MHz memory
⎯Serial Presence Detect (SPD) memory only
⎯Unbuffered, non-registered single- or double-sided DIMMs (except double-sided
DIMMs with x16 organization)
⎯Memory configurations listed below:
•Up to 1.0 GB utilizing 256 Mb technology
•Up to 2.0 GB utilizing 512 Mb technology
•Up to 4.0 GB utilizing 1 Gb technology
•Up to 8.0 GB utilizing 2 Gb technology
•A minimum of 512 MB of total memory is required
NOTE
System resources and hardware (such as PCI Express) require physical memory
address locations that can reduce available addressable system memory. This could
result in a reduction of as much as 1 GB or more of physical addressable memory
being available to the operating system and applications, depending on the system
configuration and operating system.

Intel Manageability
Intel offers IT organizations tamper-resistant and persistent management capabilities.
Intel®Standard Manageability is a hardware-based solution that uses out of band
communication to manage access to client systems in addition to offering encrypted
and persistent asset management and remote diagnostics and/or recovery capabilities
for networked platforms. With Intel manageability, IT organizations can easily get
accurate platform information, and can perform remote updating, diagnostics,
debugging and repair of a system, regardless of the state of the operating system or
the power state of the system.
The Intel manageability subsystem consists of:
•ARC4 microcontroller embedded in the Intel 82Q45 GMCH
•ICH10D (Intel®Management Engine (Intel®ME) function))
•Intel 82567LM Gigabit (10/100/1000 Mb/s) Ethernet LAN controller
•Channel A DIMM
•BIOS/SPI Flash
•On-board Intel®Active Management Technology (Intel®AMT) status indicator
NOTE
Software with Intel manageability capability is required to take advantage of the Intel
platform management capabilities.
Intel®Active Management Technology Status Indicator
The Intel AMT status indicator (red LED) shows the current state of the Intel
Management Engine. Table 5 shows the states of the Intel Management Engine as
indicated by the LED. Figure 3 shows the location of the Intel AMT status indicator.
Table 5. Intel AMT Status Indicator
LED State Indicates
Off Intel Management Engine is in the off state.
On Intel Management Engine is in the on state and fully functional.
Blinking Intel Management Engine is in the M1 state; system is out of band; Intel
Management Engine is functional.

Hi-Speed 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). 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 SATA channels (3.0 Gb/s) including two internal
and one external. Each channel can support one device.
