full-speed USB device.
The desktop board supports up to 10 USB 2.0 ports via ICH8 six ports routed to the
back panel and four ports routed to two internal USB 2.0 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.
18
Desktop Board Features
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.
Enhanced IDE Interface
The desktop board’s IDE interface handles the exchange of information between the
processor and peripheral devices such as hard disk drives and CD-ROM drives. The
interface supports:
• Up to two IDE devices (such as hard drives)
• ATAPI-style devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols
Serial ATA
The desktop board supports six Serial ATA channels (3.0 Gb/s) via ICH8, connecting
one device per channel.
Expandability
For system expansion, the desktop board provides the following:
• One PCI Express x16 connector
• One PCI Express x1 connector
• Two PCI bus connectors
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the
PCI/PCI Express and IDE auto-configuration utilities, and the video BIOS. The BIOS is
stored in a Serial Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions on page
Serial ATA and IDE Auto Configuration
If you install a Serial ATA or IDE device (such as a hard drive) 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 a
Serial ATA or IDE device. You can override the auto-configuration options by
specifying manual configuration in the BIOS Setup program.

Intel Desktop Board DG965MQ Product Guide
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.

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 PS/2 keyboard/mouse
― Power Management Event signal (PME#) wakeup support
― WAKE# signal wake-up 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.
21
Intel Desktop Board DG965MQ Product Guide
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
location of the power connectors.
Figure 28 on page 54 for the
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 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.
22
Desktop Board Features
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-toRAM) 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.
23
Intel Desktop Board DG965MQ Product Guide
+5 V Standby Power Indicator LED
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 bus connectors.
