Chassis
Chassis for platforms based on the Intel® Pentium® 4 and Celeron® processors in the 478-pin package must have an ATX12V power supply and improved ventilation. We encourage integrators using these boards to choose a chassis that complies with the ATX 2.01 (or later) specification.
Systems that contain Intel® Pentium® 4 processors operating at 3 GHz or higher require a heatsink and chassis that provide airflow adequate to ensure appropriate internal ambient temperature and cooling of the components in the system.
The fan heatsink must provide appropriate airflow for the processor and nearby board components. The boxed Intel® Pentium® 4 processors at 3 GHz or higher ship with a heatsink that supplies appropriate airflow for the processor and nearby board components.
Failure to use a fan heatsink and a chassis with appropriate airflow may result in reduced performance or, in some instances, damage to the motherboard.
Refer to System Cooling Requirements for a list of chassis that have been tested with Intel® Desktop Boards.
ATX12V power supply
ATX12V compliant power supplies differ from previous ATX power supplies. The ATX12V power supply provides an additional 12V current for the processor via a 2x2 4-pin connector that is required for proper operation.

Processor
The fan heatsink must provide appropriate airflow for the processor and nearby board components. The boxed Intel® Pentium® 4 processors at 3 GHz or higher ship with a heatsink that supplies appropriate airflow for the processor and nearby board components.
Failure to use a fan heatsink and a chassis with appropriate airflow may result in reduced performance or, in some instances, damage to the motherboard.

Graphics adapters
Intel Desktop Boards D845GEBV2, D845GERG2, and D845PEBT2 are only compatible with 1.5V AGP cards.
Intel Desktop Boards D875PBZ, D865GBF, D865GLC, and D865PERL are only compatible with 1.5V or 0.8V AGP cards.
Do not attempt to install a legacy 3.3V AGP card. The AGP connector is not mechanically or electrically compatible with legacy 3.3V AGP cards. Use of a 3.3V AGP card will result in damage to the board.
Hard drive
The ATA-66/100 (40-contact, 80-contact) cable included with Intel desktop boards can connect two drives. The cable supports the ATA-66/100 transfer protocols and is backward compatible with drives using slower IDE transfer protocols.
For the Intel® Desktop Boards featuring Serial ATA, the included cable(s) (4-conductor) supports the Serial ATA protocol and connects a single drive to the desktop board. Either end of the cable can be connected to the SATA drive or the connector on the board. Some Serial ATA drives may require a power adapter cable. Contact the manufacturer of the SATA drive to determine the best method for powering the SATA drive.
I/O peripherals (peripheral interfaces)
Intel Desktop Boards include the following: a diskette drive interface, two PS/2 ports, one serial port, one parallel port, USB 2.0 and two IDE (ATA 100/66/33) connections. Some boards also support IEEE 1394 and Serial ATA (depending on the model). Refer to the documentation that came with your board for specifications.
