Intel® Virtualization Technology (Intel® VT)
Intel® Virtualization Technology (Intel® VT) consists of components that support
virtualization of platforms based on Intel processors, thereby enabling the running of
multiple operating systems and applications in independent partitions. Each partition
behaves like a virtual machine (VM) and provides isolation and protection across
partitions. This hardware-based virtualization solution, along with virtualization
software, enables multiple usages such as server consolidation, activity partitioning,
workload isolation, embedded management, legacy software migration, and disaster
recovery.
• Intel Virtualization Technology (Intel VT)
Hardware support for processor virtualization enables simple, robust and reliable
VMM software. VMM software relies on hardware support on operational details for
the handling of events, exceptions, and resources allocated to virtual machines.

Intel TXT requires the use of a processor with Intel TXT support. Additionally, thirdparty software may also be required.
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 ICH10DO. 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
The Desktop Board supports six Serial ATA channels (3.0 Gb/s) via ICH10DO,
connecting one device per channel. One channel is configured as an eSATA channel.
Serial ATA RAID
ICH10DO supports Intel® Matrix Storage Technology 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
For information on configuring your system for RAID using Intel Matrix Storage
Technology see Chapter 4.

Intel® Rapid Recover Technology (Intel® RRT)
The Desktop Board supports Intel Rapid Recover Technology which 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:
• 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
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.
Serial ATA Auto Configuration
If you install a Serial 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 a
Serial 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.

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 or Changing Passwords” on
page 54.
Intel® Trusted Platform Module (Intel® TPM)
The Intel® Trusted Platform Module (Intel® TPM) component 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 software-based attacks.
NOTE
The Intel TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic
counters. One major function of the monotonic counters is for anti-replay protection
of the internal Intel TPM data. If the battery is removed or exhausted, the Intel TPM
data will be deleted in accordance with Trusted Computing Group guidelines. Please
read the Intel TPM user guide and back-up Intel TPM keys and data before removing
the battery.

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 52 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.
• 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-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.
