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

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.

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 29
on page 51 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
Fan Speed Control
Suspend to RAM (Instantly Available PC technology)
Resume on Ring
Wake from USB
Wake from PS/2 keyboard/mouse
PME# wakeup support
Onboard power button
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 D975XBX2 has four chassis fan connectors (three 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.
