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. 1.6.1.3 Configuration Modes A list of supported modes for the Intel GMA950 graphics controller is available as a downloadable document. For information about Refer to Supported video modes for the board Section 1.2, page 14 17 Intel Desktop Board D945GCLF2 Technical Product Specification 1.6.2 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and 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. For information about Refer to The location of the USB connectors on the back panel Figure 8, page 41 The location of the front panel USB headers Figure 9, page 42 18 Product Description 1.6.3 IDE 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 1.6.3.1 Parallel 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. For information about Refer to The location of the Parallel ATA IDE connector Figure 9, page 42 1.6.3.2 Serial 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. 19 Intel Desktop Board D945GCLF2 Technical Product Specification NOTE � Many Serial ATA drives use new low-voltage power connectors and require adapters or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ For information about Refer to The location of the Serial ATA IDE connectors Figure 9, page 42 1.7 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. 20 Product Description 1.8 S-Video Output The board supports S-Video output via a 7-pin S-Video connector supporting both 4-pin S-Video and Composite signal. 1.9 Legacy I/O Controller The I/O controller provides the following features: • One serial port • One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • Serial IRQ interface compatible with serialized IRQ support for PCI Conventional bus systems • PS/2-style mouse and keyboard interfaces • Intelligent power management, including a programmable wake-up event interface • PCI Conventional bus power management support The BIOS Setup program provides configuration options for the I/O controller. 1.9.1 Serial Port The serial port A connector is located on the back panel.

Thermal Sensors and Fan Headers 28 Product Description 1.13 Power Management Power management is implemented at several levels, including: • Software support through Advanced Configuration and Power Interface (ACPI) • Hardware support: ⎯ Power connector ⎯ Fan headers ⎯ LAN wake capabilities ⎯ Instantly Available PC technology ⎯ Wake from USB ⎯ Wake from PS/2 devices ⎯ Power Management Event signal (PME#) wake-up support 1.13.1 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 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. Table 6. Effects of Pressing the Power Switch If the system is in this …and the power switch state… is pressed for …the system enters this state Off Less than four seconds Power-on (ACPI G2/G5 – Soft off) (ACPI G0 – working state) On Less than four seconds Soft-off/Standby (ACPI G0 – working state) (ACPI G1 – sleeping state) On More than four seconds Fail safe power-off (ACPI G0 – working state) (ACPI G2/G5 – Soft off) Sleep Less than four seconds Wake-up (ACPI G1 – sleeping state) (ACPI G0 – working state) Sleep More than four seconds Power-off (ACPI G1 – sleeping state) (ACPI G2/G5 – Soft off) 29 Intel Desktop Board D945GCLF2 Technical Product Specification 1.13.1.1 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 ACPI specification for a complete description of the various system and power states.

Table 8. Wake-up Devices and Events These devices/events can wake up the computer… …from this state (Note 1) LAN S1, S3, S4, S5 (Note 1) PME# signal S1, S3, S4, S5 Power switch S1, S3, S4, S5 RTC alarm S3, S4, S5 Serial port S3 USB S3 PS/2 devices S1, S3, S4, S5 (Note 2) Note 1: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. Note 2: For PS/2 devices, if the computer is in an S4 or S5 state, only the key combination alt-PrtScn will wake the computer. 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 1.13.2 Hardware 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. 1.13.2.1 Power 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. For information about Refer to The location of the main power connector Figure 9, page 42 The signal names of the main power connector Table 16, page 45 32 Product Description 1.13.2.2 Fan 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. For information about Refer to The locations of the fan headers and thermal sensors Figure 5, page 28 The signal names of the GMCH fan header Table 14, page 44 The signal names of the chassis fan header Table 13, page 44 1.13.2.3 LAN 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 1.13.2.4 Instantly 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 1.13.2.5 Wake 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. 1.13.2.6 Wake 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. 1.13.2.7 PME# 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. 35 Intel Desktop Board D945GCLF2 Technical Product Specification Figure 6. Location of the Standby Power Indicator LED 1.13.3 ENERGY STAR* In 2007, the US Department of Energy and the US Environmental Protection Agency revised the ENERGY STAR* requirements. Intel has worked directly with these two governmental agencies to define the new requirements. This Intel Desktop Board meets the Category A requirements. For information about Refer to ENERGY STAR requirements and recommended configurations http://www.intel.com/go/energystar 36 2 Technical Reference 2.1 Memory Map 2.1.1 Addressable 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 Intel Desktop Board D945GCLF2 Technical Product Specification The amount of installed memory that can be used will vary based on add-in cards and BIOS settings. Figure 7 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses. Figure 7.

The other internal connectors/headers are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors/headers to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. 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. This section describes the board’s connectors and headers. The connectors and headers can be divided into these groups: • Back panel I/O connectors (see page 41) • Component-side connectors and headers (see page 42) 40 Technical Reference 2.2.1 Back Panel Connectors Figure 8 shows the location of the back panel connectors.

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. 2.2.2.3 Power 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. Table 16.

The total +5 V current draw for the one add-in board must not exceed 2 A. 2.6 Thermal Considerations CAUTION o A chassis with a maximum internal ambient temperature of 38 C 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 o voltage regulator area (shown in Figure 14) can reach a temperature of up to 85 C in an open chassis. 53 Intel Desktop Board D945GCLF2 Technical Product Specification Figure 14 shows the locations of the localized high temperature zones.

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 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.

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 3.4 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. 59 Intel Desktop Board D945GCLF2 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 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. 60 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 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 Refer to BIOS update utilities http://support.intel.com/support/motherboards/desktop/sb/ CS-022312.htm. 3.6.1 Language 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. 3.6.2 Custom 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. Refer to For information about Intel Integrator Toolkit http://developer.intel.com/design/motherbd/software/itk/ ® Additional Intel software tools http://developer.intel.com/products/motherboard/dg965wh/tools.htm and http://developer.intel.com/design/motherbd/software.htm 61 Intel Desktop Board D945GCLF2 Technical Product Specification 3.7 BIOS Recovery It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 28 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 28. Acceptable Drives/Media Types for BIOS Recovery Media Type Can be used for BIOS recovery? CD-ROM drive connected to the Parallel ATA interface Yes CD-ROM drive connected to the Serial ATA interface Yes USB removable drive (a USB Flash Drive, for example) Yes USB diskette drive (with a 1.44 MB diskette) No USB hard disk drive No For information about Refer to BIOS recovery http://support.intel.com/support/motherboards/desktop 62 Overview of BIOS Features 3.8 Boot 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. 3.8.1 CD-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 CD- ROM 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. 3.8.2 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 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. 3.8.3 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 3.8.4 Changing the Default Boot Device During POST Pressing the 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. Table 29. Boot Device Menu Options Boot Device Menu Function Keys Description <↑> or <↓> Selects a default boot device Exits the menu, saves changes, and boots from the selected device Exits the menu without saving changes 63 Intel Desktop Board D945GCLF2 Technical Product Specification 3.9 Adjusting Boot Speed These factors affect system boot speed: • Selecting and configuring peripherals properly • Optimized BIOS boot parameters 3.9.1 Peripheral 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. 3.9.2 BIOS 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 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.

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). Table 31. Front-panel Power LED Blink Codes Type Pattern Processor initialization complete On when system powers up, then off for 0.5 second. POST complete On when system powers up, then off for 0.5 second. BIOS update in progress Off when update begins, then on for 0.5 second, then off for 0.5 second; pattern repeats until BIOS update is complete. Video error On-off (0.5 second each) two times, then 3.0 second pause (off) between on-off blink pattern; repeat entire pattern (two on-off blinks and pause) until system is powered off. Memory error On-off (0.5 second each) three times, then 3.0 second pause (off) between on-off blink pattern; repeat entire pattern (three on-off blinks and 3-second pause) until system is powered off. Thermal warning On-off (0.5 second each) four times, then 3.0 second pause (off) between on-off blink pattern; repeat entire pattern (four on-off th blinks and 3-second pause) until 16 on blink, then end. 67 Intel Desktop Board D945GCLF2 Technical Product Specification 4.2 BIOS Beep Codes Whenever a recoverable error occurs during POST, the BIOS causes the board’s speaker to beep an error message describing the problem (see Table 32). NOTE � For Intel Desktop Board D945GCLF2, the beep code is only audible through a speaker connected to the green audio line out connector on the back panel. See Figure 3 on page 24 for information on the back panel audio connectors. Table 32. Beep Codes Type Pattern Frequency Memory error Three long beeps 1280 Hz Thermal warning Four alternating beeps: High tone: 2000 Hz High tone, low tone, high tone, low tone Low tone: 1600 Hz 4.3 BIOS Error Messages Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. Table 33 lists the error messages and provides a brief description of each. Table 33. BIOS Error Messages Error Message Explanation CMOS Battery Low The battery may be losing power. Replace the battery soon. CMOS Checksum Bad The CMOS checksum is incorrect. CMOS memory may have been corrupted. Run Setup to reset values. Memory Size Decreased Memory size has decreased since the last boot. If no memory was removed, then memory may be bad. No Boot Device Available System did not find a device to boot. 68 Error Messages and Beep Codes 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 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.

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. nd Table 38 shows the various forms of the “Lead-Free 2 Level Interconnect” mark as it appears on the board and accompanying collateral. 79 Intel Desktop Board D945GCLF2 Technical Product Specification Table 38. Lead-Free Board Markings Description Mark nd Lead-Free 2 Level Interconnect: This symbol is used to identify electrical and electronic assemblies and components in which the lead (Pb) concentration level in the board substrate and the solder connections from the or board to the components (second- level interconnect) is not greater than 0.1% by weight (1000 ppm). or 80 Regulatory Compliance and Battery Disposal Information 5.1.4 EMC Regulations Intel Desktop Board D945GCLF2 complies with the EMC regulations stated in Table 39 when correctly installed in a compatible host system.
