Intel Desktop Board DP45SG Product Guide

USB 2.0 Support

The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to back panel connectors and six ports routed to three onboard headers) via the ICH10R. 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.

Serial ATA Support

Intel Desktop Board DP45SG supports five onboard Serial ATA channels and one eSATA channel (3.0 Gb/s) via ICH10R.

Serial ATA RAID

The five onboard Serial ATA channels support the following RAID (Redundant Array of Independent Drives) levels via Intel Matrix Storage Technology:

•RAID 0 - data striping

•RAID 1 - data mirroring

•RAID 0+1 (or RAID 10) - data striping and data mirroring

•RAID 5 - distributed parity

For information on configuring your system for RAID using Intel Matrix Storage Technology go to Chapter 4.

Intel® Rapid Recover Technology (Intel® RRT)

The Desktop Board supports Intel Rapid Recover Technology which enables fast and easy recovery of your data in the event of a hard drive failure. It allows you to maintain a complete copy of your primary or master drive onto a second hard drive, the recovery drive. If the master hard drive should fail, either from a mechanical failure or the result of a virus, recovery is as simple as booting from the recovery drive. The recovery drive can be attached to your system via any standard SATA or eSATA connection.

Intel Rapid Recover Technology also provides the added benefit of allowing the recovery drive to be mounted as a read-only volume so you can quickly copy files from the recovery drive when individual files need to be recovered.

For information on configuring your system for Intel Rapid Recover Technology see Chapter 5.

Desktop Board Features

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the PCI/PCI Express auto-configuration utilities. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device.

The BIOS can be updated by following the instructions on page 61 in Chapter 3.

Serial ATA Auto Configuration

If you install a Serial ATA device (such as a hard drive) in your computer, 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 device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.

PCI* and PCI Express* Auto Configuration

If you install a PCI/PCI Express add-in card in your computer, 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.

Intel Desktop Board DP45SG Product Guide

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.

Hardware Management

The hardware management features of Intel Desktop Board DP45SG enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following:

•Fan speed monitoring and control

•Thermal and voltage monitoring

•Chassis intrusion detection

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

•Monitoring of power supply voltages to detect levels above and below acceptable values

•Intel Precision Cooling Technology fan speed control, delivering acousticallyoptimized thermal management

•A thermal sensor in the processor and a remote thermal sensor on the board

•Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed

Intel® Precision Cooling Technology

Intel Precision Cooling Technology automatically adjusts processor fan speed based on the processor temperature and adjusts chassis fan speeds based on the internal system temperature.

Desktop Board Features

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. See Figure 23 for the location of the chassis intrusion header.

Power Management

Power management is implemented at several levels, including software support through the Advanced Configuration and Power Interface (ACPI) and the following hardware support:

•Power connectors

•Fan headers

•LAN wake capabilities

•Instantly Available PC technology (Suspend to RAM)

•+5 V standby power indicator LED

•Wake from USB

•PCI Power Management Event signal (PME#) wakeup support

•PCI Express WAKE# signal wakeup support

•Wake from Consumer IR

Software Support

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.

Hardware Support

Power Connectors

ATX12V-compliant power supplies can turn off the computer power through system control. When an ACPI-enabled computer receives the correct command, the power supply removes all non-standby voltages.

When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (either on or off). The computer’s response can be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.

The Desktop Board has three power connectors. See Figure 26 on page 52 for the location of the power connectors.

Intel Desktop Board DP45SG Product Guide

Fan Headers

The function/operation of the fans is as follows:

•The fans are on when the computer is in the ACPI S0 state.

•The fans are off when the computer is in the ACPI S3, S4, or S5 state.

•Each fan header is wired to a tachometer input of the hardware monitoring and control device.

•All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.

•All fan headers have a +12 V DC connection.

The Desktop Board has a 4-pin processor fan header, one 4-pin and two 3-pin chassis fan headers.

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, 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.

LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer.

Instantly Available PC Technology

CAUTIONS

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.

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. If the computer has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. When signaled by a wake-up device or event, the computer quickly returns to its last known awake state.

Desktop Board Features

The Desktop Board supports the PCI Bus Power Management Interface Specification. Add-in cards that support this specification can participate in power management and can be used to wake the computer.

+5 V Standby Power Indicator

CAUTION

If the AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices.

The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is standby power still present on the board even when the computer appears to be off. For example, when this LED is lit, standby power is still present at the memory module sockets and the PCI/PCI Express connectors.

Figure 3. Location of the Standby Power Indicator

Intel Desktop Board DP45SG Product Guide

Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB and an operating system that supports Wake from USB.

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

PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

Wake from CIR

Consumer IR device activity wakes the computer from an ACPI S1 or S3 state.
