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.

CAUTION

Failure to use the appropriate power supply (below) and/or not connecting the 12 V (2x2) power

connector to the desktop board may result in damage to the board, or the system may not function

properly.

Main 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 dual or single channel memory configurations defined in Table 6.

• Memory configuration listed below:

⎯ Up to 2.0 GB utilizing 256 Mb technology

⎯ Up to 4.0 GB utilizing 512 Mb or 1 Gb technology

NOTE

System resources (such as PCI and PCI Express) require physical memory address locations that

reduce available memory addresses above 3 GB. This may result in less than 4 GB of memory

being available to the operating system and applications.
