Processor
Intel Desktop Board D2500HN includes a passively-cooled, dual-core Intel Atom
processor with integrated graphics and memory controller. The processor is soldered
to the Desktop Board and is not customer upgradeable.
NOTE
The board is designed to be passively cooled in a properly ventilated chassis. Chassis
venting locations are recommended above the processor heatsink area for maximum
heat dissipation effectiveness.
System Memory
NOTE
To be fully compliant with all applicable Intel®SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD)
data structure. If your memory modules do not support SPD, you will see a
notification to this effect on the screen at power up. The BIOS will attempt to
configure the memory controller for normal operation.
The Desktop Board has two 204-pin DDR3 SO-DIMM sockets with gold-plated contacts.
These sockets support:
•Support for DDR3 1066/1333/1600 MHz SO-DIMMs (DDR3 1333 MHz and
DDR3 1600 MHz SO-DIMMs operate at 1066 MHz only)
•Serial Presence Detect (SPD) memory only
•Non-ECC memory
•Up to 4 GB of memory

Intel®NM10 Express Chipset
The Intel NM10 Express Chipset is a centralized controller for the board’s I/O paths.
For more information about the Intel NM10 Express Chipset, go to
http://www.intel.com/products/chipsets/index.htm?iid=prod+prod_chipset.
Onboard Audio Subsystem
The onboard audio subsystem supports both Intel HD Audio and AC ’97 Audio. The
subsystem is based on the following components:
•Intel NM10 Express Chipset
•RealTek ALC662 audio codec
The subsystem includes the following headers and connectors:
•Three back panel analog audio jacks
•Onboard S/PDIF digital audio output header
•Front panel audio header (supports both Intel HD Audio and AC ’97 Audio),
including functionality for:
―Line out (headphones/speaker)
―Microphone in
The board supports 2-channel audio output from the back panel analog ports with jack
detection as indicated in Table 3. The front/back panel audio connectors are
configurable through the audio device driver control panel.

NOTE
The back panel audio line out connector is designed to power amplified speakers or
headphones only. Poor audio quality occurs if passive (non-amplified) speakers are
connected to this output.
Legacy Input/Output (I/O) Controller
The legacy I/O controller provides the following legacy features:
•One parallel port via a back panel connector
•Two serial ports via one back panel port and one onboard header
•Intelligent power management, including a programmable wake-up event interface
•Low pin count (LPC) interface
•PCI power management support
The BIOS Setup program provides configuration options for the Legacy I/O Controller.

Desktop Board Features

LAN Subsystem
The LAN subsystem consists of the following:
•Intel NM10 Express Chipset
•Intel 82574L Gigabit Ethernet Controller for 10/100/1000 Mb/s Ethernet LAN
connectivity
•RJ-45 LAN connector with integrated status LEDs
Additional features of the LAN subsystem include:
•CSMA/CD protocol engine
•LAN connect interface that supports the Ethernet controller
•Conventional PCI bus power management
Supports ACPI technology
Supports LAN wake capabilities
LAN drivers are available from Intel’s World Wide Web site at
http://downloadcenter.intel.com/.
Two LEDs are built into the RJ-45 LAN connector located on the back panel (see
Figure 3). These LEDs indicate the operating states of the LAN.

USB 2.0 Support
The Desktop Board supports up to eight USB 2.0 ports (four ports routed to the back
panel and four ports routed to two front panel USB 2.0 headers). The USB 2.0 ports
are 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 High-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.
NOTE
Computer systems that have an unshielded cable attached to a USB port might not
meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.
SATA Interface
The Desktop Board supports two SATA channels (3.0 Gb/s) that support one device
per channel. The SATA controller supports IDE and ACHI configuration and can
operate in both legacy and native modes.
Expandability
The Desktop Board provides PCI bus connector. The connector can support either a
single PCI add-in card or a single- or dual-slot PCI riser card.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI
and SATA auto-configuration utilities, and the video BIOS.
PCI Auto Configuration
If you install a PCI add-in card in your computer, the PCI 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 add-in card.

Desktop Board Features
19
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 Passwords on page 37.
Hardware Management Features
The board’s hardware management features enable the board to be compatible with
the Wired for Management (WfM) specification. The board’s hardware management
features include thermal and voltage monitoring.
The hardware monitoring and fan control subsystem is based on the Nuvoton
W83627DH-P legacy I/O controller, which supports the following:
•Processor and system ambient temperature monitoring
•System fan speed monitoring
•Power monitoring of +12 V, +5 V, +5 Vstdby, +3.3 V, and +VCCP
•SMBus interface

Intel Desktop Board D2500HN Product Guide
20
Power Management Features
Power management is implemented at several levels, including:
•Software support through the Advanced Configuration and Power Interface (ACPI)
•Hardware support:
―Power connector
―Fan header
―+5 V standby power indicator LED
―LAN Wake capabilities
―Instantly Available PC technology
―Wake from USB
―Wake from PS/2
―PME# wakeup support
―Wake from serial port
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
Fan Header
The Desktop Board has a 3-pin system fan header. See Figure 10 on page 34 for the
location of the system fan header.
+5 V Standby Power Indicator
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 4, is lit when there is
standby power to the system. This includes the SO-DIMM sockets and the PCI bus
connector, even though the computer appears to be off.
