Hi-Speed USB 2.0 Support

NOTE

Use a shielded cable that meets the requirements for a full-speed USB device. 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.

NOTE

USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.

The desktop board supports up to eight USB 2.0 ports via ICH5R; six ports routed to the back
panel and two routed to the internal USB 2.0 header. 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.

Desktop Board Features

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 auto­configuration 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

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.

Power Management Features

Power management is implemented at several levels, including:

• Software support through Advanced Configuration and Power Interface (ACPI) and Advanced
Power Management (APM)

• Hardware support:
 Suspend to RAM (Instantly Available PC technology)
 Power connectors
 Fan connectors
 Chassis intrusion
 Resume on Ring
 Wake from USB
 Wake from PS/2 keyboard/mouse
 PME# wakeup support

ACPI

ACPI gives the operating system direct control over the power management and Plug & Play
functions of a computer. The use of ACPI with the desktop board requires an operating system that
provides full ACPI support.

APM

APM makes it possible for the computer to enter an energy-saving standby mode. The standby
mode can be initiated in the following ways:

• Time-out period specified in the BIOS Setup program

• From the operating system, such as the standby menu item in Windows 98SE

In standby mode, the board may reduce power consumption by spinning down hard drives, and
reducing power to or turning off of VESA* DPMS-compliant monitors. APM can be enabled or
disabled in the BIOS Setup program. While in standby mode, the system retains the ability to
respond to external interrupts and service requests, such as incoming faxes or network messages.
Any keyboard or mouse activity brings the system out of standby mode and immediately restores
power to the monitor.

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 effect ACPI S3 sleep state functionality.

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.

22

Desktop Board Features

The desktop board’s standby power indicator, shown in Figure 2, 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.

OM15682

Figure 2. Location of the Standby Power Indicator

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.

Intel Desktop Board D875PBZ Product Guide

fans connected to the front and rear chassis fan connectors. The processor fan connector is not
controlled.

The fan speed control feature can be disabled in the BIOS, resulting in the chassis fans always
operating at full speed. This feature should be disabled if a self-controlled fan is attached to a
chassis fan connector.

The overall system noise reduction will vary based on system configuration and environment.

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.

Related Links:

Go to page 46 for the location of the chassis intrusion header.

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

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

NOTE

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

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.

24

Desktop Board Features

Speaker

A speaker is mounted on the desktop board. The speaker provides audible error code (beep code)
information during the Power-On Self-Test (POST).
