Product Description

1.5System Memory

The board has one 240-pin DIMM socket and supports the following memory features:

1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts

Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.

2 GB maximum total system memory

Minimum total system memory: 128 MB

Non-ECC DIMMs

Serial Presence Detect

DDR2 533 MHz or DDR2 400 MHz SDRAM DIMMs (DDR2 800 MHz and DDR2 667 MHz validated to run at 533 MHz only)

NOTE

To be fully compliant with all applicable DDR2 SDRAM memory specifications, the board should be populated with 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, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency.

Table 3 lists the supported DIMM configurations.

1.6.1.2Dynamic Video Memory Technology (DVMT)

DVMT enables enhanced graphics and memory performance through Direct AGP, and highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 224 MB of system memory can be allocated to DVMT on systems that have 512 MB or more of total system memory installed. Up to 128 MB can be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system memory. Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem.

DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions.

NOTE

The use of DVMT requires operating system driver support.

1.6.1.3Configuration Modes

The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCIand EHCI-compatible drivers.

The ICH7 provides the USB controller for all ports. The port arrangement is as follows:

Four ports are implemented with dual stacked back panel connectors

Four ports are routed to two separate front panel USB headers

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.

Product Description

1.6.3IDE Support

The board provides three IDE interface connectors:

One parallel ATA IDE connector that supports two devices

Two serial ATA connectors that support one device per connector

1.6.3.1Parallel ATE IDE Interface

The ICH7’s Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The Parallel ATA IDE interface supports the following modes:

Programmed I/O (PIO): processor controls data transfer.

8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec.

Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec.

ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.

ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH7’s ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.

NOTE

ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling.

The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes.

The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS.

1.6.3.2Serial ATA Interfaces

The ICH7’s Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed on each port for a maximum of two Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel.

For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE 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.

1.7Real-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.

1.13.1.1System 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.

NOTE

The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.

31

Intel Desktop Board D945GCLF2 Technical Product Specification

1.13.2Hardware Support

CAUTION

Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options.

The board provides several power management hardware features, including:

Power connector

Fan headers

LAN wake capabilities

Instantly Available PC technology

Wake from USB

PME# signal wake-up support

Wake from PS/2 devices

LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line.

NOTE

The use of Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support.

1.13.2.1Power Connector

ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system 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 (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu.

1.13.2.2Fan Headers

The function/operation of the fan headers is as follows:

The fans are on when the board is in the S0 state.

The fans are off when the board is off or in the S3, S4, or S5 state.

The chassis fan header supports closed-loop fan control that can adjust the fan speed and is wired to a fan tachometer input.

All fan headers have a +12 V DC connection.

1.13.2.3LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply.

LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in the following ways:

The PCI bus PME# signal for PCI 2.3 compliant LAN designs

By Ping

Magic Packet

The onboard LAN subsystem

33

Intel Desktop Board D945GCLF2 Technical Product Specification

1.13.2.4Instantly Available PC Technology

CAUTION

For Instantly Available PC technology, the +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Instantly Available PC technology can damage the power supply.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to- RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 8 on page 31 lists the devices and events that can wake the computer from the S3 state.

The board supports the PCI Bus Power Management Interface Specification. Add-in boards that also support this specification can participate in power management and can be used to wake the computer.

The use of Instantly Available PC technology requires operating system support and PCI 2.3 compliant add-in cards and drivers.

34

Product Description

1.13.2.5Wake from USB

USB bus activity wakes the computer from ACPI S1 and S3 state.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB and support in the OS.

1.13.2.6Wake from PS/2 Devices

PS/2 device activity wakes the computer from an ACPI S1, S3, S4, or S5 state. However, when the computer is in an S4 or S5 state, the only PS/2 activity that will wake the computer is the alt-PrtScrn key combination on the keyboard.

1.13.2.7PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).

1.13.2.8+5 V Standby Power Indicator LED

The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 6 shows the location of the standby power indicator LED.

CAUTION

If 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.

2.1Memory Map

2.1.1Addressable Memory

The board utilizes 2 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 2 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)

GMCH base address registers, internal graphics ranges

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

37

2.2.2.2Add-in Card Connectors

The board has one PCI Conventional (rev 2.3 compliant) bus add-in card connector. PCI Conventional bus add-in cards with SMBus support can access sensor data and other information residing on the board.

Note the following considerations for the PCI Conventional bus connectors:

The PCI Conventional bus connector is bus master capable.

SMBus signals are routed to the PCI Conventional bus connector. This enables PCI Conventional 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.

2.2.2.3Power Supply Connectors

The board has the following power supply connectors:

Main power – a 2 x 12 connector. This connector is compatible with 2 x 10 connectors previously used on Intel Desktop Boards. The board supports the use of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When using a power supply with a 2 x 10 main power cable, attach that cable on the rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24 unconnected.

ATX12V power – a 2 x 2 connector. This connector provides power directly to the processor voltage regulator and must always be used. Failure to do so will prevent the board from booting.

2.5.3Add-in Board Considerations

The board is designed to provide 2 A (average) of +5 V current for the one add-in board. The total +5 V current draw for the one add-in board must not exceed 2 A.

2.6Thermal 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 2.8.

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 14) can reach a temperature of up to 85 oC in an open chassis.

3 Overview of BIOS Features

3.1Introduction

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 LF94510J.86A.

When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match.

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.

3.2BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 4 Mbit (512 KB) flash memory device.

3.3Resource Configuration

3.3.1PCI* 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.

58

Overview of BIOS Features

3.4System 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.

59

Intel Desktop Board D945GCLF2 Technical Product Specification

3.5Legacy 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 access 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

3.6BIOS 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 hard drive), or a CD-ROM, or from the file location on the Web.

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 hard drive), or a CD-ROM.

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

3.6.1Language Support

The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrator’s Toolkit utility. Check the Intel website for details.

3.6.2Custom Splash Screen

During POST, an Intel® splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Intel® Integrator’s Toolkit that is available from Intel can be used to create a custom splash screen.

NOTE

If you add a custom splash screen, it will share space with the Intel branded logo.

Overview of BIOS Features

3.8Boot Options

In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drive, USB drive, USB flash drive, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. If enabled, the last default boot device is the network.

3.8.1CD-ROM Boot

Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CDROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive.

3.8.2Network 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.

3.8.3Booting 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

3.8.4Changing 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 29 lists the boot device menu options.

Intel Desktop Board D945GCLF2 Technical Product Specification

3.9Adjusting Boot Speed

These factors affect system boot speed:

Selecting and configuring peripherals properly

Optimized BIOS boot parameters

3.9.1Peripheral Selection and Configuration

The following techniques help improve system boot speed:

Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays.

Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time.

Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process.

Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly.

3.9.2BIOS Boot Optimizations

Use of the following BIOS Setup program settings reduces the POST execution time.

In the Boot Menu, set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time.

In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time.

NOTE

It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen.

This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program).

64

Overview of BIOS Features

3.10 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 30 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen.

4.1BIOS Front-panel Power LED Codes

The front-panel power LED blinks off and on to display messages. For example, the power LED is on when the system is powered on, and blinks off for 0.5 second when processor initialization is complete. In addition, whenever a recoverable error occurs during POST, the BIOS causes the front-panel power LED to blink an error message describing the problem (see Table 32).

Error Messages and Beep Codes

4.4Port 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 PCI bus connector 1.

The following tables provide information about the POST codes generated by the BIOS:

Table 34 lists the Port 80h POST code ranges

Table 35 lists the Port 80h POST codes themselves

Table 36 lists the Port 80h POST sequence

NOTE

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

5.1.3.3Lead Free Intel Desktop Board

This Intel Desktop Board is a European Union Restriction of Hazardous Substances (EU RoHS Directive 2002/95/EC) compliant product. EU RoHS restricts the use of six materials. One of the six restricted materials is lead.

This Intel Desktop Board is lead free although certain discrete components used on the board contain a small amount of lead which is necessary for component performance and/or reliability. This Intel Desktop Board is referred to as “Lead-free second level interconnect.” The board substrate and the solder connections from the board to the components (second-level connections) are all lead free.

China bans the same substances and has the same limits as EU RoHS; however it requires different product marking and controlled substance information. The required mark shows the Environmental Friendly Usage Period (EFUP). The EFUP is defined as the number of years for which controlled listed substances will not leak or chemically deteriorate while in the product.

Table 38 shows the various forms of the “Lead-Free 2nd Level Interconnect” mark as it appears on the board and accompanying collateral.
