for front panel audio connectors)
•S/PDIF audio header (1 x 4 pin header)
•Internal mono speaker header (1 x 2 pin header)
Front panel headphone output is supported by a separate audio channel pair, allowing
multi-streaming audio configurations such as simultaneous 6-channel (5.1) surround
sound playback and stereo audio conferencing (through speakers connected to the
back panel audio connectors and a headset connected to front panel audio
connectors).
The onboard internal mono speaker header allows connection to an internal, low-
power speaker for basic system sound capability. The subsystem is capable of driving
a speaker load of 8 Ωat 1 W (rms) or 4 Ωat 1.5 W (rms).
The onboard S/PDIF header allows connection to coaxial or optical adapters for digital
audio output.
The back panel audio connectors are configurable through the audio device drivers.

USB Support
The Desktop Board supports USB 2.0. There are 14 USB 2.0 ports (six ports routed to
back panel connectors and eight ports routed to four onboard headers). The USB 2.0
ports are high-speed, 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.
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)
•Two internal SATA 3.0 Gb/s connectors (black)
•Two onboard eSATA 3.0 Gb/s connectors (red) for connection to an eSATA adapter
SATA RAID
The Intel Q67 PCH supports Intel®Rapid Storage Technology (Intel®RST) which
enables the following RAID (Redundant Array of Independent Drives) levels:
•RAID 0 - data striping
•RAID 1 - data mirroring
•RAID 0+1 (or RAID 10) - data striping and mirroring
•RAID 5 - distributed parity
NOTE
In order to use supported RAID features, you must first enable RAID in the BIOS. Also,
during Microsoft Windows XP installation, you must press F6 to install the RAID
drivers. See your Microsoft Windows XP documentation for more information about
installing drivers during installation. Both Microsoft Windows Vista and Microsoft
Windows 7 include the necessary RAID drivers for both AHCI and RAID without the
need to install separate RAID drivers using the F6 switch in the operating system
installation process.

Desktop Board Features
19
Intel®Rapid Recover Technology
The board incorporates Intel®Rapid Recover Technology (Intel®RRT). Intel RRT is a
feature of Intel RST. Intel RRT uses RAID 1 (mirroring) functionality to copy data from
a designated master drive to a designated recovery drive. The master drive data can
be copied to the recovery drive either continuously or on request.
When using the continuous update policy, changes made to the data on the master
drive while the recovery drive is disconnected or offline are automatically copied to the
recovery drive when it is reconnected. When using the on request update policy, the
master drive data can be restored to a previous state by copying the data on the
recovery drive back to the master drive.
Expandability
Intel Desktop Board DQ67OW provides the following expansion capability:
•One PCI Express 2.0 x16 interface
•One PCI Express 2.0 x4 interface
•One PCI Express 2.0 x1 interface
•One Conventional PCI bus interface
Legacy I/O
The board’s Legacy I/O Controller provides the following legacy features:
•A parallel port back panel connector
•A diskette drive interface
•One PS/2 back panel connector for mouse/keyboard support
•One serial port header
•Serial IRQ interface compatible with serialized IRQ support for Conventional PCI
bus systems
•Intelligent power management, including a programmable wake-up event interface
•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 67.

Intel Desktop Board DQ67OW Product Guide
20
SATA Auto Configuration
If you install a SATA device (such as a hard disk 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
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.
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 60.
