Desktop Board Features

USB Support

The Desktop Board supports USB 3.0 and USB 2.0. USB 3.0 is supported via two USB 3.0 ports (blue) on the back panel. USB 3.0 ports are backward compatible with USB 2.0 and USB 1.1 devices. The USB 3.0 ports are SuperSpeed, high-speed, fullspeed, and low-speed capable. USB 3.0 support requires both an operating system and drivers that fully support USB 3.0 transfer rates.

There are 10 USB 2.0 ports (two ports routed to back panel connectors (black) and eight ports routed to four onboard headers (black)). The USB 2.0 ports are highspeed, full-speed, and low-speed capable. USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates.

NOTE

Intel recommends connecting USB keyboard and mouse devices to USB 2.0 ports (black). Operating system installation may be interrupted if keyboard and mouse devices are connected to the SuperSpeed USB 3.0 ports (blue) due to the lack of native USB 3.0 driver support from the operating system. The device driver for the USB 3.0 host controller must be installed from the included Intel® Express Installer Driver and Software DVD before it can be operational in the operating system.

SATA Support

The board provides six SATA channels, through the PCH, which support one device per channel:

•Two internal SATA 6.0 Gb/s connectors (blue)

•Conventional PCI bus power management support

The BIOS Setup program provides configuration options for the Legacy I/O controller.

BIOS

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

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

SATA Auto Configuration

If you install a SATA device (such as a hard disk 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 SATA device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.

PCI*/PCI Express Auto Configuration

If you install a Conventional PCI or 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 Conventional PCI or PCI Express add-in card.

20

Desktop Board Features

BIOS 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, go to Clearing Passwords on page 54.

Intel Manageability Technology

Intel offers IT organizations tamper-resistant and persistent management capabilities. With Intel manageability, IT organizations can easily get accurate platform information, and can perform remote updating, diagnostics, debugging and repair of a system, regardless of the state of the operating system or the power state of the system.

The Intel manageability subsystem consists of:

•Intel® Management Engine (Intel® ME) microcontroller embedded in the Intel H61 PCH

•BIOS/SPI Flash

Intel® MEBX Reset Header

This header (see Figure 3) allows you to reset the Intel ME configuration to factory defaults. Momentarily shorting pins 1 and 2 with a jumper (not supplied) will accomplish the following:

•Return all Intel ME parameters to their default values.

•Delete any user entered information, including PID/PPS and user entered Hash Certificates. USB key and remote configuration data will be removed if the parameters are not default parameters.

•Reset the Intel MEBX password to the default value (admin).

NOTE

Software with Intel manageability capability is required to take advantage of the Intel platform management capabilities.

Trusted Platform Module (TPM) Support

Intel Desktop Board DH61BE provides a header to connect to an external TPM. The header is shown in Figure 1, S on page 12 and the header pinout is listed in Table 9 on page 48. TPMs are designed to enhance platform security by providing a protected space for key operations and other security critical tasks. Using both hardware and software, the TPM protects encryption and signature keys at their most vulnerable stages—operations when the keys are being used unencrypted in plain-text form. TPMs shield unencrypted keys and platform authentication information from softwarebased attacks.

Desktop Board Features

Fan Speed Control and Hardware Monitoring

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

•Thermal sensors in the processor and the Intel PCH, as well as near the processor voltage regulators and system memory

•Monitoring of system voltages to detect levels above or below acceptable values

•Thermally monitored closed-loop fan control for all three fans that can adjust fan speed as needed

•Support for 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.

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 support

•Wake from serial devices

•Wake from PS/2 devices

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.

Intel Desktop Board DH61BE Product Guide

The Desktop Board has two power connectors. See Figure 22 on page 52 for the location of the power connectors.

Fan Headers

The function/operation of the fans is as follows:

•The fans are on when the board 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.

•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.

•All fan headers are controlled by Pulse Width Modulation.

•The front and rear chassis fan headers support Linear Fan Control on 3-wire fans.

The Desktop Board has a 4-pin processor fan header and two 4-pin chassis fan headers that are compatible with 4-wire and 3-wire chassis fans.

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

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. 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 (the power supply is off and the front panel power LED will behave as configured by the BIOS “S3 State Indicator” option). When signaled by a wake-up device or event, the system quickly returns to its last known wake state.

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.
