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.
16
Desktop Board Features
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
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 35 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.
See Chapter 3 on page 57 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 autoconfiguration 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.
17
Intel Desktop Board D975XBX Product Guide
PCI and PCI Express* Auto Configuration
If you install a PCI/PCI Express add-in card in your desktop board, the PCI/PCI Express autoconfiguration 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.

For instructions on resetting the password, see Clearing Passwords on page 50.
Chassis Intrusion
The desktop 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 28 on page 48 for the location of the chassis intrusion header.
Power Management Features
Power management is implemented at several levels, including:
•Advanced Configuration and Power Interface (ACPI)
•Hardware support:
Fan connectors
Suspend to RAM (Instantly Available PC technology)
Resume on Ring
Wake from USB
Wake from PS/2 keyboard/mouse
PME# wakeup support
18
Desktop Board Features
ACPI
ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support.
Fan Connectors
Desktop Board D975XBX has three chassis fan connectors (two 3-pin and one 4-pin) and one processor fan connector (4-pin).
Fan Speed Control (Intel® Precision Cooling Technology)
Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds.
The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel® boxed processors. Disabling the chassis fan speed control results in chassis fans always operating at full speed. The chassis fan speed control feature should be disabled if a self-controlled chassis fan is attached to any controlled chassis fan header.
The overall system noise reduction will vary based on system configuration and environment.
Suspend to RAM (Instantly Available PC Technology)
CAUTION
For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or affect ACPI S3 sleep state functionality.
CAUTION
Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up device or event, the system quickly returns to its last known awake state.
The desktop board’s standby power indicator, shown in Figure 3, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.

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.
