(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

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.

Table 3 lists the supported SO-DIMM configurations.

• 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 max imum supported resolution is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the DVI 1.0 specification.

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.

For information about Refer to

The location of the USB connectors on the back panel Figure 9, page 39 The location of the front panel USB headers 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 a nd 1 5 ). 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.

Intel Desktop Board D2550DC2 Technical Product Specification

1.6 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 po w er fail, custom defaults, if previously saved, will be l oaded into CMOS RAM at power-on.

When the voltage drops b elow 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 wi th 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.

1.11 Power Management

Power management is implemented at several levels, including:

• Software support through Advanced Configuration and Power Interface (ACPI)

• Hardware support:

 Power connector  Fan header  LAN wake capabilities  Instantly Available PC techno logy  Wake from USB  Power M a na gement Event signal (PME#) wake-up support  WAKE# signal wake-up support

1.11.1 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 boa rd requires an operating system that provides full ACPI support. A C PI features include:

• Plug and Play (including bus and device enumeration)

• Power management control of individual devices, add-in boards (some add-

in boards may require an ACPI-aware driver), video displays, and hard disk drives

• Methods for achieving less than 15-watt system operation in the power- on/standby sleeping state

• A Soft-off feature that enables the operating system to power-off the computer

• Support for multiple wake-up events (see Table 8 on page 31)

• Support for a front panel power and sleep mode switch

Table 6 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system.

1.11.1.1 System States and Power State s

Under ACPI, the operating system directs all system and device power state transitions. The opera ting sy stem 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.

2.1 Memory Map

2.1.1 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 syste m m emory installed, it is not possible to use all of the installed memor y due to system address space being allocated for other system critical functions. T hese 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 cards

Intel Desktop Board D2550DC2 Technical Product Specification

The amount of installed memory that can be used will vary based on add-in cards and BIOS settings. Figure 8 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses.

2.2.2.2 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 B# (B7)  INT C# (A7)  INT D# (B8)

NOTE

The Conventional PCI slot on this board does not support the PCI PHOLD1 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.

PHOLD is the signal required to hold the bus during DMA transfers.

2.5.2 Add-in Board Considerations

The board is designed to provide 2 A (average) of +5 V current for the Conventional PCI slot. The total +5 V current draw for the Conventional PCI expansion s lot (total load) must not exceed 2 A.

2.6 Thermal Considerations

CAUTION

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:

http://www3.intel.com/cd/channel/reseller/asmo-na/eng/tech_reference/53211.htm

All responsibility for determining the adequacy of any thermal or system design remains solely with the system integrator. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance.

CAUTION

Ensure that the ambient temperature does not exceed the board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the ma ximum operating temperature, see the environmental specifications in Section 2.9.

2.6.1 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 sho uld 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 s cenario 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 us ed to complement the TMDG.

2.6.1.4 Chassis Design Guideline

The pin fin heatsink design used on this board w ill 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, lea ding 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 T 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.

A should be capped at 50 °C. Chassis inlet vents should

3 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 P lug and Play support.

The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs a re 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 oper a ting system boot begins. The men u bar is shown below .

NOTE

The maintenance menu is displayed only when the b oard is in configure mode. Section 2.3 on page 50 shows how to put the board in configure mode.

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 8 Mb (1024 KB) flash memory device.

3.3 Resource Configuration

3.3.1 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 co nsidered to be available for use by the add-in card.

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 Infor mation 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 f or 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 obta in the SM BIOS information. Additional board informat io n can be found in the BIOS under the Additional Informatio n h eader under the Main BIOS page.

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 US B . 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 US B 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 load s. While the operating syste m 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 S etup 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 suppo rts USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installa tion instruct ions.

Overview of BIOS Features

3.6 BIOS Updates

The BIOS can be updat ed 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

Both utilities verify that the updated BIOS m a tches the target system to prevent accidentally installing an incompatib le BIOS.

NOTE

Review the instructions distributed with the upgrad e utility before attempting a BIOS update.

For information about Refer to

BIOS update utilities http://downloadcenter.intel.com

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.

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.

3.6.1 BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; howeve r, if an interruption occurs, the BIOS could be damaged. Table 29 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable.

Table 29. Acceptable Drives/Media Types for BIOS Recovery

3.7 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 supp orted in compliance to the El Torito bootable CD-ROM format specification. U nder 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 fro m 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.

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 bo ot device menu to be displayed. This menu displays the list of available boot devices (as set in the BIOS setup program’s Boot Device Priority submenu). Table 30 lists the boot device menu options.

3.8 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 table is for reference only and is not displayed on the screen.

Board Status and Error Messages

4.4 Port 80h POST Codes

During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the P OST 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 ca n d ecode 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 ab out the POST codes generated by the BIOS:

• Table 35 lists the Port 80h POST code ranges

• Table 36 lists the Port 80 h POST codes themselves

• Table 37 lists the Port 80h POST sequence

NOTE

In the tables listed above, all POST codes and range values are listed in hexadecimal.
