Desktop Board Features

Hi-Speed USB 2.0 Support

The Desktop Board supports up to ten USB 2.0 ports (four ports routed to the back panel and six ports routed to three internal 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.

Serial ATA Support

The Desktop Board supports six SATA channels (3.0 Gb/s) including five internal and one external eSATA channel. Each channel can support one device.

Expandability

For system expansion, the Desktop Board provides the following expansion connectors:

•One PCI Express 2.0 x16 connector

•One PCI Express 1.1 x1 connector

•Two PCI bus connectors

BIOS

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

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

ATA Auto Configuration

If you install an 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 an 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.

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, see “Clearing or Changing Passwords” on page 53.

Desktop Board Features

Hardware Management Features

The hardware management features of Intel Desktop Board DB43LD 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

Fan Speed, Thermal, and Voltage Monitoring and Control

The board’s fan speed, thermal, and voltage monitoring and control features include the following:

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

•Intel Quiet System Technology fan speed control, delivering acoustically-optimized thermal management

NOTE

Memory must be installed in the Channel A DIMM socket to enable Intel Quiet System Technology.

•Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed according to thermal conditions.

•Fan speed controllers and sensors integrated into ICH10D

•Thermal sensors in the processor, GMCH, and ICH10D, plus an onboard remote sensor

NOTE

The minimum thermal reporting threshold for the GMCH is 66 °C. The GMCH thermal sensor will display 66 °C until the temperature rises above this point.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. A mechanical switch on the chassis can be connected to the chassis intrusion header on the Desktop Board. See Figure 20 for the location of the chassis intrusion header.

Power Management Features

Power management is implemented at several levels, including:

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

•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

Power Management Event signal (PME#) wakeup support

WAKE# signal wake-up support

Wake from PS/2 devices

Wake from serial port

•ENERGY STAR 4.0 and 5.0 Category A capable

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 two power connectors. See Figure 23 on page 51 for the location of the power connectors.
