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 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.  
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 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.  
Related Links:  
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.

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.

Recovering the BIOS  
It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the  
BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails.  
The following procedure uses recovery mode for the Setup program. See page 49 for more  
information on Setup modes.  
NOTE  
Because of the small amount of code available in the boot block area, there is no video support.  
You will not see anything on the screen during this procedure. Monitor the procedure by listening  
to the speaker and looking at the diskette drive LED.  
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external  
peripherals.

5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to  
boot. The recovery process will take a few minutes.  
6. Listen to the speaker:  
Upon applying power, drive A will begin to show activity. In about a minute, two beeps  
are heard and drive A activity ceases (temporarily) indicating the successful recovery of the  
BIOS core. Drive A activity will begin again followed by two more beeps indicating the  
successful recovery of the boot block. This sequence of events indicates a successful BIOS  
recovery.  
A series of continuous beeps indicates a failed BIOS recovery.  
7. If recovery fails, return to step 1 and repeat the recovery process.  
8. If recovery is successful, turn off the computer, and disconnect its power cord.  
9. Remove the computer cover and continue with the following steps.  
10. On the jumper block, reinstall the jumper back on pins 1-2 as shown below to set normal mode  
for Setup.
