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 numérique 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.

Main Memory

NOTE

To be fully compliant with all applicable Intel® SDRAM memory specifications, the desktop 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 below:

• Four 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline Memory Module (DIMMs) connectors with gold-plated contacts.

• Support for:

Unbuffered, non-registered single or double-sided DIMMs ECC and non-ECC DDR2 800/667/533 MHz memory Serial Presence Detect (SPD) memory only 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

• Up to 8.0 GB utilizing 1 Gb technology

Desktop Board Features

NOTE

Regardless of the DIMM type used, the memory frequency will either be equal to or less than the processor system bus frequency. For example, if DDR2 667 memory is used with a 533 MHz system bus frequency processor, the memory will operate at 533 MHz. Table 3 lists the resulting operating memory frequencies based on the combinatio

n of DIMMs and processors.

Desktop Board Features

LAN Subsystem

The LAN, with the Intel 82801GH I/O Controller Hub, provides a Fast PCI LAN subsystem. The LAN subsystem provides the following functions:

• Intel 82573L Ethernet LAN supporting 10/100/1000 Mbit/sec

• Support for RJ-45 connector with status indicator LEDs

• Configurable EEPROM that contains the MAC address

LAN Subsystem Software

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 eight USB 2.0 ports via ICH7; four ports routed to the back panel and four routed to two 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.

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.

Enhanced IDE Interface

The ICH7 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 two 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

Serial ATA

The desktop board supports eight Serial ATA channels, connecting one device per channel in either a RAID or a non-RAID configuration.

Expandability

For system expansion, the desktop board supports the following:

• One PCI Express x16 card as an electrical x16 card or two PCI Express x16 cards as electrical x8 cards

• One PCI Express x16 card as an electrical x4 card

• Two PCI bus add-in cards

Related Links

For information about installing a PCI Express x16 card, see page 38 in Chapter 2.

Desktop Board Features

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.

See Chapter 3 on page 59 for more information about the BIOS.

Serial ATA and IDE Auto Configuration

If you connect a Serial ATA or IDE device (such as a hard drive) to your desktop board, the 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 a Serial ATA or IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.

When booting from a Serial ATA device, the device connected to Serial ATA connector 0 is the first boot device and the device connected to Serial ATA connector 3 is the last boot device by default.

PCI and PCI Express* Auto Configuration

If you install a PCI/PCI Express add-in card in your desktop board, the PCI/PCI Express 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/PCI Express add-in card.

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 BIOS 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.

Intel Desktop Board D975XBX2 Product Guide

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from either ACPI S1 or ACPI S3 state

• Requires only one call to access the computer

• Detects incoming call similarly for external and internal modems

• Requires modem interrupt be unmasked for correct operation

Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

USB bus activity wakes the computer from an ACPI S1 or S3 state.

Wake from PS/2* Keyboard/Mouse

PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state.

PME# Wakeup Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, or S5 state.
