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
use the equipment.
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 édictépar le ministére des
Communications du Canada.

Processor
CAUTION
Failure to use an ATX12V power supply, or not connecting the 12 V processor core voltage power
supply connector to Desktop Board D865PCD may result in damage to the desktop board and/or
power supply.
Desktop Board D865PCD supports a single Intel Pentium 4 processor or Intel Celeron processor.
Processors are not included with the desktop board and must be purchased separately.
The processor connects to the Intel desktop board through the mPGA478-pin socket. The Intel®
processors may be removed and replaced to accommodate supported higher speed processors.
Desktop Board D865PCD supports the processors listed in Table 3.

Input/Output (I/O) Controller
The super I/O controller features the following:
• Low pin count (LPC) interface
• One serial port
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) support
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• PS/2-style mouse and keyboard interfaces
• Interface for one 1.44 MB or 2.88 MB diskette drive
• Intelligent power management, including a programmable wake up event interface
• PCI power management support
Hi-Speed USB 2.0 Support
NOTE
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable.
Use a shielded cable that meets the requirements for a full-speed USB device.
The desktop board supports up to six USB 2.0 ports via ICH5; four ports routed to the back
panel and two routed to the internal USB 2.0 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.
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.
NOTE
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.

Desktop Board Features
19
Enhanced IDE Interface
The ICH5’s IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer.
The interface supports:
• Up to four 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
• Laser Servo (LS-120) drives
Accelerated Graphics Port (AGP)
NOTE
Desktop Board D865PCD is only compatible with 0.8 V and 1.5 V AGP cards.
The AGP connector is keyed for 0.8 V and 1.5 V AGP cards only; the connector is not mechanically
compatible with legacy 3.3 V AGP cards. Do not attempt to install a legacy 3.3 V AGP card.
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.
AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.
The AGP 3.0 connector supports 8x, 4x, and 1x AGP cards.
Related Links
For information about installing the AGP card, see page 32 in Chapter 2.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be updated by following the instructions in Chapter 3 on page 47.
PCI Auto Configuration
If you install a PCI add-in card in your computer, the PCI 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 add-in card.
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE 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 an IDE device. You can override the auto-
configuration options by specifying manual configuration in the BIOS Setup program.
To use ATA-66/100 features, the following items are required:
• An ATA-66/100 peripheral device
• An ATA-66/100 compatible cable
• ATA-66/100 operating system device drivers

Intel Desktop Boards D865PCD Product Guide
20
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
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.
Chassis Intrusion
The board supports a chassis security feature that detects if the chassis cover has been removed.
The security feature uses a mechanical switch on the chassis that can be connected to the chassis
intrusion header on the desktop board. See Figure 10 on page 37 for the location of the chassis
intrusion header.
