Desktop Board Features
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 ICH9DO. 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.
Enhanced IDE Interface
The 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 ICH9DO,
connecting one device per channel. One channel is configured as an eSATA channel.
Serial ATA RAID
The ICH9DO supports 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
For information on configuring your system for RAID using Intel
Technology see Chapter 4.

Intel® Rapid Recover Technology
Intel Rapid Recover Technology enables fast and easy recovery of your data in the
event of a hard drive failure. It allows you to maintain a complete copy of your
primary or master drive onto a second hard drive, the recovery drive. If the master
hard drive should fail, either from a mechanical failure or the result of a virus,
recovery is as simple as booting from the recovery drive. The recovery drive can be
attached to your system via any standard SATA or eSATA connection.
Intel Rapid Recover Technology also provides the added benefit of allowing the
recovery drive to be mounted as a read-only volume so you can quickly copy files from
the recovery drive when individual files need to be recovered.
For information on configuring your system for Intel Rapid Recover Technology see
Chapter 5.
Expandability
For system expansion, the Desktop Board provides the following expansion slots:
• Two PCI Express x1 connectors
• One PCI Express x16 connector
• One PCI bus connector
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 the Serial Peripheral Interface (SPI) Flash.
The BIOS can be updated by following the instructions on page 65 in Chapter 3.
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.
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.

Desktop Board Features
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 BIOS Security Pass
page 58.
Hard Disk Drive Passwords
The hard disk drive password security feature will lock a particular drive from read or
write accesses until the hard disk drive password is entered at the startup prompt.
Passwords are set in BIOS Setup under the “Security” heading, but do not interact
with other system passwords.
There are two levels of hard disk drive passwords: Master and User. Both the Master
and User hard disk drive passwords can be used to unlock a locked drive. Valid
passwords are between two and eight characters.
The passwords function as follows:
• The User hard disk drive password will lock the drive and block read and write
accesses to a hard disk upon each power cycle or reset.
• The Master hard disk drive password by itself will not lock the drive, but instead
acts as an unlock override in the event that the User hard disk drive password is
unavailable. Only the installation of the User hard disk drive password will cause a
hard disk to be locked upon a system power cycle or reset.
For convenient support of S3 resume, the system BIOS will automatically unlock drives
on resume from S3 and will not prompt for a hard disk drive password.

NOTE
The BIOS hard disk drive password security feature can only be used on ATA hard
disks that support the ATA Security Mode feature set. It supports Serial ATA hard disk
drives in IDE, AHCI, and RAID modes.

Intel Desktop Board DQ35JO Product Guide
Hard Disk Drive Password Feature During BIOS POST
During every BIOS POST execution, if a User hard disk drive password is present on
the hard drive, POST execution will pause to prompt the user to enter the Master or
User password:
Enter Hard Disk Drive Password:
Upon successful entry of the Master or User hard disk drive password, the system will
continue with normal POST.
If the hard disk drive password is not correctly entered, the system will go back to the
above prompt. The user will have three attempts to correctly enter the correct hard
disk drive password. After the third unsuccessful attempt, the system will halt with
the following message:
Hard Disk Drive Password Entry Error
The BIOS will then lock the drive from further activity, requiring a power-cycle to reattempt hard disk drive password entry.
Trusted Platform Module (TPM)
The TPM 1.2 device is designed to enhance platform security above and beyond the
capabilities of today’s software 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. The TPM is specifically designed
to shield unencrypted keys and platform authentication information from softwarebased attacks.
For information about enabling and activating the TPM, refer to the Trusted Platform
Module (TPM) Quick Reference Guide.
Hardware Management Features
The hardware management features of Desktop Board DQ35JO 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

Desktop Board Features
Hardware Monitoring and Fan Speed Control
The features of the hardware monitoring and fan speed control include:
• 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.
• Fan speed controllers and sensors integrated into the ICH9DO
• Thermal sensors in the processor, GMCH, and ICH9DO, 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 its temperature rises above this point.
• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed or switch the fans off as needed
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 24 on
page 50 for the location of the cha
ssis intrusion header.

Intel Desktop Board DQ35JO Product Guide
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 27 on page 56 for the
location of the power co
nnectors
.
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.
