• CPIS 1.5 compliant

• Spread spectrum clocking

• Panel power sequencing

• Integrated PWM interface for LCD backlight inverter control

Intel Desktop Board D425KT and Intel Desktop Board D425KTW Technical Product Specification

1.5.1.4 Configuration Modes

For monitors attached to the VGA port, video modes supported by this board are based on the Extended Display Identification Data (EDID) protocol.

Video mode configuration for LVDS displays (D425KTW only) is supported as follows:

• Automatic panel identification via Extended Display Identification Data (EDID) for LVDS panels supporting EDID protocol.

• Manual LVDS panel configuration through the BIOS setup page. This feature allows the manual entry of critical panel settings (equivalent to the 18-byte Detailed Timings Descriptor structure defined by the VESA EDID specification) for non-EDID panel support.

In addition, BIOS setup provides the following configuration parameters for LVDS displays (D425KTW only):

• Screen Brightness: allows the end-user to set screen brightness for the display.

• Maintain Aspect Ratio: allows the end-user to select whether the native aspect

ratio is to be preserved during POST and before the video driver is loaded.

• LVDS Configuration Changes: allows the system integrator to “lock” critical settings of the LVDS configuration to avoid end-users potentially rendering the display unusable (refer to Note 1).

• Inverter Frequency and Polarity: allows the system integrator to set the operating frequency and polarity of the panel inverter board.

• Minimum Inverter Current Limit (%): allows the system integrator to set minimum PWM%, as appropriate, according to the power requirements of the LVDS display and the selected inverter board.

NOTE

Support for LVDS (D425KTW only) configuration complies with the following:

1. “Unlocking” of critical settings of the LVDS configuration is supported via Intel Integrator Toolkit’s command-line tool.

2. Critical settings of the LVDS configuration are not exposed through Intel Integrator Toolkit or Intel

3. Critical settings of the LVDS configuration will not be overwritten by loading BIOS setup defaults.

4. Critical settings of the LVDS configuration will be preserved across BIOS updates.

Product Description

1.5.2 USB

The board provides up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The port arrangement is as follows:

• Eight USB 2.0 ports (D425KT only): ⎯ Four back panel ports ⎯ Four ports are implemented with two dual port internal headers for front panel

cabling

• Seven USB 2.0 ports (D425KTW only): ⎯ Four back panel ports ⎯ Two ports are implemented with a dual port internal header for front panel

cabling

⎯ One port is implemented with an internal header (brown-colored) that supports

an Intel

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

Z-U130 USB Solid-State Drive or compatible device

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 Gbits/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 PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows Vista* operating systems.

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 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 11 shows the location of the battery.

1.7 Legacy I/O Controller

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 board requires an operating system that provides full ACPI support. ACPI 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 29)

• 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, dependi

ng on how ACPI is configured with an ACPI-aware operating system.

1.11.1.1 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 AC 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 PCI Conventional 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 (4 MB)

• Local APIC (19 MB)

• Direct Media Interface (40 MB)

• Front side bus interrupts (17 MB)

• Internal graphics address registers

• Memory-mapped I/O that is dynamically allocated for PCI Conventional add-in

cards

2.5.2 Add-in Board Considerations

The board is designed to provide 2 A (average) of +5 V current for the PCI Conventional slot. The total +5 V current draw for the PCI Conventional expansion slot (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.

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://developer.intel.com/design/motherbd/cooling.htm

All responsibility for determining the adequacy of any thermal or system design remains solely with the reader. 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 maximum operating temperature, see the environmental specifications in Section 2.9.

Technical Reference

CAUTION

Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area (shown in Figure 16) can reach a temperature of up to 85 an open chassis.

Figure 16 shows the locations of the localized high temperature zones.

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 chassis fan.

This information should be used in conjunction with the Thermal/Mechanical Specifications and Design Guidelines (TMSDG) published for Intel

Atom™ D400 and D500 Series processors. The TMSDG contains detailed package information and thermal mechanical specifications for the processors. The TMSDG 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 (pages 29-30), the information in this section can also be used to complement the TMSDG.

2.6.1.4 Chassis Design Guideline

The pin fin heatsink design used on this board will be able to dissipate up to 13 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 micro-ATX chassis with a chassis fan. The recommended fan type is an exhaust fan.

For best thermal performance, it is recommended that the chassis fan provide reasonable airflow directly over the 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 chassis fan should be located near the board region in order to effectively regulate airflow (see Figure 17). A chassis fan located further away from the board region, i.e., at the optical disk drive or hard disk driv

e region, will be less effective in controlling the local ambient temperature. Regardless of where the chassis 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 chassis fan enabled should have local ambient temperature safely below the 50 °C limit.

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

For all chassis configurations, the heatsink performance parameter, Ψ

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.

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 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 MWPNT10N.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.

Maintenance Main Advanced Security Power Boot Exit

NOTE

The maintenance menu is displayed only when the board is in configure mode. Section 2.3 on page 49 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 Mbit (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 considered 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 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.

Intel Desktop Board D425KT and Intel Desktop Board D425KTW 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.

Overview of BIOS Features

3.6 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site:

• Intel

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.

For information about Refer to

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

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.

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.

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 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.

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 Boot Device Priority submenu). Table 35 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.

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 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:

• Table 40 lists the Port 80h POST code ranges

• Table 41 lists the Port 80h POST codes themselves

• Table 42 lists the Port 80h POST sequence
