Integration Guide: Assembly
Before You Begin - Warning and Cautions
WARNING
Disconnect the desktop board's power supply from its AC power source before you connect or disconnect cables, or install or remove any board components. Failure to do this can result in personal injury or equipment damage. Some circuitry on the desktop board can continue to operate even though the front panel power switch is off.
CAUTION
Electrostatic discharge (ESD) can damage desktop board components. Install the board at an ESD-controlled workstation. If such a workstation is not available, wear an antistatic wrist strap or touch the surface of the antistatic package before handling the board.
CAUTION
Many of the midboard and front panel connectors provide operating voltage (+5 V DC and +12 V DC, for example) to devices inside the computer chassis, such as fans and internal peripherals. These connectors do not have overcurrent protection. Do not use these connectors for powering devices external to the computer chassis. A fault in the load presented by the external devices could cause damage to the computer, the interconnecting cables, and the external devices themselves. _______________________________________________________________________________________

_______________________________________________________________________________________
Install the I/O Shield
The board comes with an I/O shield that is used to block radio frequency transmissions, necessary to pass emissions (EMI) certification testing, protect internal components from dust and foreign objects, and promote correct airflow within the chassis.
Install the I/O shield before installing the board in the chassis. Place the shield inside the chassis as shown in the figure below. Press the shield into place so that it fits tightly and securely.
Install the Desktop Board
Refer to your chassis manual for specific instructions on installing and removing the desktop board. Secure the board to the chassis using the screws provided with the chassis. If you have a BTX-based board and chassis, be sure to first install the SRM that comes with the BTX chassis, if not already pre-installed. Refer to the Quick Reference Guide that came with the board for the location of the screw mounting holes.
The recommended torque range for standard low carbon steel # 6-32 screws is 6 - 10 in-lb.
Install the Processor
Refer to http://support.intel.com/support/processors/pentium4/inuse.htm for detailed processor installation information.
Select your board from this list to view supported processors for your desktop board.
CAUTION
Before installing or removing the processor, make sure the AC power has been removed by unplugging the power cord from the computer; the standby power LED should not be lit (see Figure 3 on page 23). Failure to do so could damage the processor and the board.
To install a processor, follow these instructions:
1. Open the socket lever by pushing the lever down (A) and away (B) from the socket.
2. Lift the load plate. Do not touch the socket contacts.
3. Remove the plastic protective socket cover from the load plate. Do not discard the protective socket cover. Always replace the socket cover if the processor is removed from the socket.
4. Remove the processor from the protective processor cover. Hold the processor only at the edges, being careful not to touch the bottom of the processor. Do not discard the protective processor cover. Always replace the processor cover if the processor is removed from the socket.
5. Hold the processor with your thumb and index fingers oriented as shown in the figure below. Make sure fingers align to the socket cutouts (A). Align notches (B) with the socket (C). Lower the processor straight down without tilting or sliding the processor in the socket.
6. Pressing down on the load plate (A) close and engage the socket lever (B).
Install the Processor Fan Heatsink or Thermal Module
For complete instructions on how to attach the processor fan heat sink (for ATX-based boards) or thermal module (for BTX-based boards), refer to the boxed processor manual.
Connect the processor fan heat sink cable to the 4-pin processor fan header. A fan with a 4-pin connector is recommended; however, a fan with a 3-pin connector can be used. Since the 3-pin fan cannot use the onboard fan control, the fan will always operate at full speed.
For ATX-based boards:
 For BTX-based boards:
Install Memory Modules
Select from the links below to view the list of memory modules tested with your desktop board.
Install memory in the DIMM slots prior to installing any PCI Express video card to avoid interference with the PCI Express slot retention mechanism. Intel Desktop Boards based on the Intel® 945 chipsets and later support dual channel memory. Refer to Single / Dual Channel Memory for complete information on configuring dual channel memory mode.
To install a DIMM, follow these steps:
- Turn off all peripheral devices connected to the computer. Turn off the computer and disconnect the AC power cord.
- Remove the computers cover and locate the DIMM sockets.
- Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position.
- Holding the DIMM by the edges, remove it from its anti-static package.
- Position the DIMM above the socket. Align the small notch at the bottom edge of the DIMM with the keys in the socket.
- Insert the bottom edge of the DIMM into the socket.
- When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips snap into place. Make sure the clips are firmly in place.
- Replace the computers cover and reconnect the AC power cord.
Install Chassis Fans
Intel Desktop Boards support up to three chassis fans. Connect the fans to the board fan headers, as shown below. Refer to the documentation that came with your desktop board for the location of the chassis fan headers.
Attach Front Panel Connectors
Attach the front panel connector. Refer to Front Panel 9-Pin Header for pin-out details.
Install Back Panel I/O (Optional)
Some Intel Desktop Boards include either a back panel USB bracket or a back panel USB/IEEE1394 bracket. You may also purchase these types of brackets. To install:
- Attach the bracket to the chassis back panel.
- Connect the USB cable to an onboard USB header.
- For brackets with IEEE1394, connect the IEEE1394 cable to an onboard IEEE-1394 header.
Install Front Panel I/O (Optional)
Some Intel Desktop Boards include a front panel USB/IEEE1394/Audio 3.5" module. You may also purchase these types of modules. To Install:
- Insert the 3.5" module into a drive bay on the chassis.
- Connect the USB cable to an onboard USB header.
- Connect the IEEE1394 cable(s) to the onboard IEEE-1394 header(s).
- Connect the audio cable to the onboard front panel audio header.
Install Floppy Drive
To Install:
1. Install the drive in an empty chassis bay.
2. Attach the data and power cables to the drive.
3. Attach the data cable to the desktop boards floppy connector.
Install Serial ATA Devices (Hard Drives)
For the Intel Desktop Boards supporting Serial ATA, two or four SATA cables are included. The cable (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.
For correct SATA cable function:
- Attach a cable end to the connector on the board.
- Attach the other cable end to the drive.
Intel does not support the use of IDE to serial-ATA converters, however limited testing indicates that such converters may work with the Serial ATA feature of Intel Desktop Boards.
For additional information on Serial ATA, refer to Information on Using Serial ATA Hard Drives.
Install IDE Devices (Hard Drives / DVD / CDROM)
Intel Desktop Boards support Ultra ATA/66 and Ultra ATA/100 transfer rates. If you are using an Ultra ATA/66 or Ultra ATA/100 hard drive, you must use the 40-pin, 80-conductor IDE cable. Both the board and the cable are backward compatible with previous IDE transfer protocols. Install the IDE cable in the following orientation:
- Attach the cable end with the single connector to the board.
- Attach the cable end with the two closely spaced connectors to the drives.
Connect CD-ROM Audio
(Applicable to desktop boards that include on-board audio.)
Some older operating systems require that an additional audio cable be connected from the CD-ROM drive to the motherboard in order listen to CD's directly from the CD-ROM drive. In this situation, connect the CD-ROM audio cable to the connector labeled "CD IN".
Note: Not all Intel desktop boards include this connector. Refer to On board CD-ROM Connector No Longer Required for more information.
Install Add-In PCI Express Graphics (Optional)
Care must be taken when installing a PCI Express card into a PCI Express x16 slot. When installing any PCI Express card in the desktop board, ensure that it is fully seated in the connector before you power on the system. If the card is not fully seated, an electrical short may result across the PCI Express slot pins. Depending on the over-current protection of the power supply, certain board components and/or traces may be damaged.
Connect Devices to Back Panel Connectors
Refer to this diagram for connecting cables properly. Note: The connectors shown in the graphic may not all be applicable to your system. Refer to the documentation that came with your desktop board.
Connect Power Cables
Connect the power cables. Note: The types of connectors used on the Intel Desktop Boards can vary. Refer to the documentation that came with your board for specific power connection instructions.
Finishing Up
To finish installation of your desktop board:
- BIOS settings for advanced system configuration (optional).
- Install the Operating System: Window Vista*, Windows* XP or Windows* 2000.
- Install the Intel Desktop Board drivers and applications.
