Hi-Speed USB 2.0 Support
The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to the back panel and six ports routed to three internal headers) via ICH10. 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.
ATA Support
The board includes five ATA interface connectors:
•One PATA connector that supports two devices
•Four SATA connectors that support one device each
PATA Interface
The board’s discrete PATA controller provides one bus-mastering PATA interface that is accessible through a standard IDE connector The PATA interface supports the following modes:
•Programmed I/O (PIO): the processor controls data transfer.
•8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/s.
•Ultra DMA: DMA protocol on the ATA bus supporting host and target throttling and transfer rates of up to 33 MB/s.
•ATA-66: DMA protocol on the ATA bus supporting host and target throttling and transfer rates of up to 66 MB/s. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.
•ATA-100: DMA protocol on the ATA bus allows host and target throttling.
19
Intel Desktop Board DG43GT Product Guide
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling.
The PATA interface also supports ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes.
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS.
SATA Interfaces
The ICH10 SATA controller provides four independent SATA ports with a theoretical maximum transfer rate of 3.0 Gb/s on each port. One device can be installed on each port for a maximum of four SATA devices. A point-to-point interface is used for host to device connections, unlike PATA which supports a master/slave configuration and two devices on each channel.
For compatibility, the underlying SATA functionality is transparent to the operating system. The SATA controller supports IDE and AHCI configuration and can operate in both legacy and native modes. In Legacy mode, standard ATA I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows Vista* operating systems.
Expandability
For system expansion, the Desktop Board provides the following expansion slots:
•One PCI Express 2.0 x16 connector (compatible with PCI Express 1.1 add-in cards)
•Two PCI Express 1.1 x1 connectors
•One PCI bus connector
20
Desktop Board Features
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 a Serial or Parallel ATA device in your computer, 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 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 or 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 Passwords in the BIOS Setup Program” on page 55.

Intel Desktop Board DG43GT Product Guide
Hardware Management Features
The hardware management features of Intel Desktop Board DG43GT 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 0 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 the ICH10
•Thermal sensors in the processor, GMCH, and ICH10, 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. 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 22 for the location of the chassis intrusion header.

Desktop Board Features
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
Wake from serial
Power Management Event signal (PME#) wakeup support
WAKE# signal wake-up support
Wake from PS/2
•ENERGY STAR qualified
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 25 on page 53 for the location of the power connectors.
23
Intel Desktop Board DG43GT 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.
•All fan headers support closed-loop fan control that can adjust the fan speed according to thermal conditions.
•All fan headers have a +12 V DC connection.
The Desktop Board has a 4-pin processor fan header 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.
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.
24
Desktop Board Features
+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 green LED is lit, standby power is still present at the memory module sockets and the PCI/PCI Express bus connectors.
Figure 3. Location of the +5 V Standby Power Indicator
For more information on standby current requirements for the Desktop Board, refer to the Technical Product Specification at http://support.intel.com/support/motherboards/desktop/.
Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S1 or S3 state.
Wake from Serial
Serial bus activity wakes the computer from an ACPI S1 or 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.
