System Memory
The board has two 204-pin DDR3 SO-DIMM sockets and supports the following
memory features:
•
•
•
•
•
•
•
DDR3 SDRAM SO-DIMMs with gold-plated contacts

Minimum total system memory: 256 MB
Non-ECC DIMMs
Serial Presence Detect
DDR3 1066 MHz, DDR3 1333 MHz, DDR3 1600 MHz SO-DIMMs
(DDR3 1333 MHz and DDR3 1600 MHz memory will run at 1066 MHz)
NOTES
•
Due to passively-cooled thermal constraints, system memory must have an
operating temperature rating of 85 oC.
The board is designed to be passively cooled in a properly ventilated
chassis. Chassis venting locations are recommended above the system
memory area for maximum heat dissipation effectiveness.
•
If you are installing only one SO-DIMM, it must be installed in the bottom
socket (SO-DIMM 1).
•
To be fully compliant with all applicable DDR3 SDRAM memory
specifications, the board should be populated with SO-DIMMs that support
the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read the SPD data and program the chipset to accurately configure memory
settings for optimum performance. If non-SPD memory is installed,
performance and reliability may be impacted or the SO-DIMMs may not
function under the determined frequency.

balancing of 2-D/3-D graphics performance and overall system performance. Dynamic
allocation of system memory to video memory is as follows:
•
•
•
•
256 MB total RAM results in 32 MB video RAM
512 MB total RAM results in 64 MB video RAM
1 GB total RAM results in 128 MB video RAM
2 GB total RAM results in 224 MB video RAM
1.5.1.2
Digital Visual Interface (DVI-D)
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the
DVI 1.0 specification.
20
Product Description
1.5.2
USB
The board provides up to seven USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers (four ports routed to the back panel and three
ports routed to two front panel USB 2.0 headers). One of the front panel USB headers
(brown-colored) supports an Intel Z-U130 USB Solid-State Drive or compatible device.
NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet
FCC Class B requirements, even if no device is attached to the cable. Use shielded
cable that meets the requirements for full-speed devices.

Figure 11, page 41
1.5.3
SATA Support
The board provides two SATA interface connectors that support one device per
connector.
The board’s SATA controller offers 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 two 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 Conventional PCI bus
resource steering is used. Native mode is the preferred mode for configurations using
the Windows Vista* operating system.

Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the
computer is not plugged into a wall socket, the battery has an estimated life of three
years. When the computer is plugged in, the standby current from the power supply
extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC
with 3.3 VSB applied.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 13 shows the location of the battery.
1.7
Legacy I/O Controller
The Legacy I/O Controller provides the following features:
•
•
•
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.

System States and Power States
Under ACPI, the operating system directs all system and device power state
transitions. The operating system puts devices in and out of low-power states based
on user preferences and knowledge of how devices are being used by applications.
Devices that are not being used can be turned off. The operating system uses
information from applications and user settings to put the system as a whole into a
low-power state.
Table 7 lists the power states supported by the board along with the associated system
power targets. See the ACPI specification for a complete description of the various
system and power states.

Addressable Memory
The board utilizes 4 GB of addressable system memory. Typically the address space
that is allocated for Conventional PCI bus add-in cards, PCI Express configuration
space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total
system memory). On a system that has 4 GB of system memory installed, it is not
possible to use all of the installed memory due to system address space being
allocated for other system critical functions. These functions include the following:
•
•
•
•
•
BIOS/ SPI Flash (2 MB)
Local APIC (19 MB)
Direct Media Interface (40 MB)
Internal graphics address registers
Memory-mapped I/O that is dynamically allocated for Conventional PCI

Add-in Card Connectors
The board has the following add-in card connectors:
•
•
PCI Express Full-/Half-Mini Card slot
Conventional PCI bus connector (with riser card support for up to two PCI
cards)
Note the following considerations for the Conventional PCI bus connector:
•
•
The Conventional PCI bus connector is bus master capable.
SMBus signals are routed to the Conventional PCI bus connector. This
enables Conventional PCI bus add-in boards with SMBus support to access
sensor data on the board. The specific SMBus signals are as follows:
 The SMBus clock line is connected to pin A40.
 The SMBus data line is connected to pin A41.
The Conventional PCI bus connector also supports single-slot and dual-slot riser cards
for use of up to two bus master PCI expansion cards. In order to support two PCI bus
master expansion cards, the riser card must support the following PCI signal routing:
•
•
•
Pin A11: additional 33 MHz PCI clock
Pin B10: additional PCI Request signal (i.e., PREQ#2)
Pin B14: additional PCI Grant signal (i.e., GNT#2)
NOTE
BIOS IRQ programming for the second PCI slot on PCI riser card:
•
•
ID_SEL: AD20 (Device 4)
Second PCI slot INT Mapping:
 INT A# (A6)  INT D# of mother board PCI slot.
 INT B# (B7)  INT A# of mother board PCI slot.
 INT C# (A7)  INT B# of mother board PCI slot.
 INT D# (B8)  INT C# of mother board PCI slot.
NOTE
The Conventional PCI slot on this board does not support the PCI PHOLD 1 function.
Due to this limitation (errata), certain PCI cards may experience performance or
detection issues when DMA transfer is used as part of the PCI card operation.
1
PHOLD is the signal required to hold the bus during DMA transfers.

A chassis with a maximum internal ambient temperature of 38 oC at the processor fan
inlet is a requirement. Whenever possible, use of a processor heat sink that provides
omni-directional airflow to maintain required airflow across the processor voltage
regulator area is recommended.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel Desktop Boards please refer to the
following website:

Passive Heatsink Design in a Passive System
Environment
This section highlights important guidelines and related thermal boundary conditions
for passive heatsink design in a passive system environment. Passive heatsink
describes a thermal solution without a fan attached. Passive system environment
describes a chassis with either a power supply fan or a built-in system fan.
This information should be used in conjunction with the Thermal and Mechanical
Design Guide (TMDG) published for the Intel Atom processor D2000 series. The TMDG
contains detailed package information and thermal mechanical specifications for the
processors. The TMDG also contains information on how to enable a completely fanless
design provided the right usage scenario and boundary conditions are observed for
optimal thermal design. While the TMSDG has a section on thermal design for passive
system environments (page 32), the information in this section can also be used to
complement the TMDG.
2.6.1.1
Definition of Terms

Description
TA
The measured ambient temperature locally surrounding the processor. The ambient
temperature should be measured just upstream of a passive heatsink.
TJ
Processor junction temperature.
ΨJA
Junction-to-ambient thermal characterization parameter (psi). A measure of thermal
solution performance using total package power. Defined as (TJ - TA)/TDP.
Note: Heat source must be specified for Ψ measurements.
TIM
Thermal Interface Material: the thermally conductive compound between the heatsink
and the processor die surface. This material fills the air gaps and voids, and enhances
the transfer of the heat from the processor die surface to the heatsink.
TDP
Thermal Design Power: a power dissipation target based on worst-case applications.
Thermal solutions should be designed to dissipate the thermal design power.
TA external
The measured external ambient temperature surrounding the chassis. The external
ambient temperature should be measured just upstream of the chassis inlet vent.

Chassis Design Guideline
The pin fin heatsink design used on this board will be able to dissipate up to 10 W of
processor power in most of the passively enabled system chassis. This board is
targeted for 3-7 liters volumetric or larger, desktop/tower orientation, mini-ITX and
microATX chassis with a system fan. The recommended fan type is an exhaust fan.
For best thermal performance, it is recommended that the system fan provide
reasonable airflow directly over all the major components on the board. The pin fin
heatsink is designed to have the best thermal performance when airflow direction is
parallel to the heatsink fins.
The processor on the board will generate the highest amount of heat, leading to high
ambient temperature within the chassis. The system fan should be located near the
board region in order to effectively regulate airflow (see Figure 18). A system fan
located further away from the board region, i.e., at the optical disk drive or hard disk
drive region, will be less effective in controlling the local ambient temperature.
Regardless of where the system fan is located, the maximum local ambient
temperature as defined by TA should be capped at 50 °C. Chassis inlet vents should
also provide adequate openings for airflow to pass through. The recommended freearea-ratio of chassis vents should be equal to or greater than 0.53. By using the
reference pin fin heatsink, most chassis with a system fan enabled should have local
ambient temperature safely below the 50 °C limit.
56
Technical Reference
Figure 18. Fan Location Guide for Chassis Selection
(Chassis Orientation is Not Restricted)
For all chassis configurations, the heatsink performance parameter, ΨJA should be less
than 3.85 °C/W. The detail thermal measurement metrology is described in the
TMSDG. For chassis that fail to meet the thermal specifications guideline highlighted
above, an actively cooled heatsink solution should be used.

Overview of BIOS Features
3.1
Introduction
The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash
contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN
EEPROM information, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The initial production BIOSs are identified as MUCDT10N.86A.
The BIOS Setup program can be used to view and change the BIOS settings for the
computer. The BIOS Setup program is accessed by pressing the <F2> key after the
Power-On Self-Test (POST) memory test begins and before the operating system boot
begins. The menu bar is shown below.

flash memory device.
3.3
3.3.1
Resource Configuration
PCI* Autoconfiguration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or
add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having
to configure the system. When a user turns on the system after adding a PCI card, the
BIOS automatically configures interrupts, the I/O space, and other system resources.
Any interrupts set to Available in Setup are considered to be available for use by the
add-in card.
62
Overview of BIOS Features
3.4
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing
computers in a managed network.
The main component of SMBIOS is the Management Information Format (MIF)
database, which contains information about the computing system and its
components. Using SMBIOS, a system administrator can obtain the system types,
capabilities, operational status, and installation dates for system components. The MIF
database defines the data and provides the method for accessing this information. The
BIOS enables applications such as third-party management software to use SMBIOS.
The BIOS stores and reports the following SMBIOS information:
•
•
•
•
BIOS data, such as the BIOS revision level
Fixed-system data, such as peripherals, serial numbers, and asset tags
Resource data, such as memory size, cache size, and processor speed
Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the
SMBIOS information. The BIOS supports an SMBIOS table interface for such operating
systems. Using this support, an SMBIOS service-level application running on a
non-Plug and Play operating system can obtain the SMBIOS information. Additional
board information can be found in the BIOS under the Additional Information header
under the Main BIOS page.
63
Intel Desktop Board D2550DC2 Technical Product Specification
3.5
Legacy USB Support
Legacy USB support enables USB devices to be used even when the operating system’s
USB drivers are not yet available. Legacy USB support is used to access the BIOS
Setup program, and to install an operating system that supports USB. By default,
Legacy USB support is set to Enabled.
Legacy USB support operates as follows:
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to
enter and configure the BIOS Setup program and the maintenance menu.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB keyboards
and mice are recognized and may be used to configure the operating system.
(Keyboards and mice are not recognized during this period if Legacy USB support
was set to Disabled in the BIOS Setup program.)
6. After the operating system loads the USB drivers, all legacy and non-legacy USB
devices are recognized by the operating system, and Legacy USB support from the
BIOS is no longer used.
7. Additional USB legacy feature options can be accessed by using Intel Integrator
Toolkit.
To install an operating system that supports USB, verify that Legacy USB support in
the BIOS Setup program is set to Enabled and follow the operating system’s
installation instructions.

BIOS Updates
The BIOS can be updated using either of the following utilities, which are available on
the Intel World Wide Web site:
•
•
•
Intel® Express BIOS Update utility, which enables automated updating while
in the Windows environment. Using this utility, the BIOS can be updated
from a file on a hard disk, a USB drive (a flash drive or a USB drive), or an
optical drive.
Intel® Flash Memory Update Utility, which requires booting from DOS.
Using this utility, the BIOS can be updated from a file on a hard disk, a USB
drive (a flash drive or a USB drive), or an optical drive.
Intel® F7 switch allows a user to select where the BIOS .bio file is located
and perform the update from that location/device. Similar to performing a
BIOS Recovery without removing the BIOS configuration jumper.
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.

Boot Options
In the BIOS Setup program, the user can choose to boot from a hard drive, optical
drive, removable drive, or the network. The default setting is for the optical drive to
be the first boot device, the hard drive second, removable drive third, and the network
fourth.
3.7.1
Optical Drive Boot
Booting from the optical drive is supported in compliance to the El Torito bootable
CD-ROM format specification. Under the Boot menu in the BIOS Setup program, the
optical drive is listed as a boot device. Boot devices are defined in priority order.
Accordingly, if there is not a bootable CD in the optical drive, the system will attempt
to boot from the next defined drive.
3.7.2
Network Boot
The network can be selected as a boot device. This selection allows booting from the
onboard LAN or a network add-in card with a remote boot ROM installed.
Pressing the <F12> key during POST automatically forces booting from the LAN. To
use this key during POST, the User Access Level in the BIOS Setup program's Security
menu must be set to Full.
66
Overview of BIOS Features
3.7.3
Booting Without Attached Devices
For use in embedded applications, the BIOS has been designed so that after passing
the POST, the operating system loader is invoked even if the following devices are not
present:
•
•
•
Video adapter
Keyboard
Mouse
3.7.4
Changing the Default Boot Device During POST
Pressing the <F10> key during POST causes a boot device menu to be displayed. This
menu displays the list of available boot devices (as set in the BIOS setup program’s

BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program
and who can boot the computer. A supervisor password and a user password can be
set for the BIOS Setup program and for booting the computer, with the following
restrictions:
•
•
•
•
•
•
•
The supervisor password gives unrestricted access to view and change all
the Setup options in the BIOS Setup program. This is the supervisor mode.
The user password gives restricted access to view and change Setup
options in the BIOS Setup program. This is the user mode.
If only the supervisor password is set, pressing the <Enter> key at the
password prompt of the BIOS Setup program allows the user restricted
access to Setup.
If both the supervisor and user passwords are set, users can enter either
the supervisor password or the user password to access Setup. Users have
access to Setup respective to which password is entered.
Setting the user password restricts who can boot the computer. The
password prompt will be 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, the user can enter either password to
boot the computer.
For enhanced security, use different passwords for the supervisor and user
passwords.
Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to
16 characters in length.
Table 31 shows the effects of setting the supervisor password and user password. This

Port 80h POST Codes
During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O
port 80h. If the POST fails, execution stops and the last POST code generated is left at
port 80h. This code is useful for determining the point where an error occurred.
Displaying the POST codes requires a PCI bus add-in card, often called a POST card.
The POST card can decode the port and display the contents on a medium such as a
seven-segment display.
NOTE
The POST card must be installed in the PCI bus connector.
The following tables provide information about the POST codes generated by the BIOS:
•
