For information about Refer to Power supply connectors Section 2.7.2.1, page 49 15 Intel Desktop Board D945GCNL Technical Product Specification 1.4 System Memory The board has two DIMM sockets 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. Refer to Section 2.1.1 on page 37 for information on the total amount of addressable memory. Minimum total system memory: 128 MB Non-ECC DIMMs Serial Presence Detect DDR2 667 or DDR2 533 MHz SDRAM DIMMs NOTES • • Remove the PCI Express x16 video card before installing or upgrading memory to avoid interference with the memory retention mechanism. To be fully compliant with all applicable DDR 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 nonSPD 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. Table 3.

This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used. Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used. For information about… Refer to: Memory Configuration Examples http://www.intel.com/support/motherboards/desktop/sb/cs011965.htm 17 Intel Desktop Board D945GCNL Technical Product Specification 1.5 Intel® 945GC Chipset The Intel 945GC chipset consists of the following devices: • • Intel 82945GC Graphics Memory Controller Hub (GMCH) with Direct Media Interface (DMI) interconnect Intel 82801GB I/O Controller Hub (ICH7) with DMI interconnect The GMCH component provides interfaces to the CPU, memory, PCI Express, and the DMI interconnect. The component also provides integrated graphics capabilities supporting 3D, 2D and display capabilities. The ICH7 is a centralized controller for the board’s I/O paths. For information about Refer to The Intel 945GC chipset http://www.intel.com/products/desktop/chipsets/index.htm Resources used by the chipset Chapter 2 1.5.1 Intel 945GC Graphics Subsystem The Intel 945GC chipset contains two separate, mutually exclusive graphics options. Either the GMA950 graphics controller (contained within the 82945GC GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI Express x16 add-in card is installed, the GMA950 graphics controller is disabled. 1.5.1.1 Intel® GMA950 Graphics Controller The Intel GMA950 graphics controller features the following: • • • 400 MHz core frequency High performance 3-D setup and render engine High quality texture engine ⎯ DX9* Compliant Hardware Pixel Shader 2.0 ⎯ Alpha and luminance maps ⎯ Texture color-keying/chroma-keying ⎯ Cubic environment reflection mapping • ⎯ Enhanced texture blending functions 3D Graphics Rendering enhancements ⎯ 1.3 Dual Texture GigaPixel/Sec Fill Rate ⎯ 16 and 32 bit color ⎯ Maximum 3D supported resolution of 1600 x 1200 x 32 at 85 Hz ⎯ Vertex cache ⎯ Anti-aliased lines ⎯ OpenGL* version 1.4 support with vertex buffer and EXT_Shadow extensions 18 Product Description • 2D Graphics enhancements ⎯ 8, 16,and 32 bit color ⎯ Optimized 256-bit BLT engine ⎯ Color space conversion • ⎯ Anti-aliased lines Video ⎯ Hardware motion compensation for MPEG2 • ⎯ Software DVD at 30 fps full screen Display ⎯ Integrated 24-bit 400 MHz RAMDAC ⎯ Up to 2048 x 1536 at 75 Hz refresh (QXGA) ⎯ DDC2B compliant interface with Advanced Digital Display 2 or 2+ (ADD2/ADD2+) cards, support for TV-out/TV-in and DVI digital display connections ⎯ Supports flat panels up to 2048 x 1536 at 60Hz or digital CRT/HDTV at 1920 x 1080 at 85 Hz (with ADD2/ADD2+) • • ⎯ Two multiplexed DVO port interfaces with 200 MHz pixel clocks using an ADD2/ADD2+ card Dynamic Video Memory Technology (DVMT) support up to 224 MB Intel® Zoom Utility For information about Refer to Obtaining graphics software and utilities Section 1.2, page 15 1.5.1.2 Dynamic 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. 19 Intel Desktop Board D945GCNL Technical Product Specification 1.5.1.3 Advanced Digital Display (ADD2/ADD2+) Card Support The GMCH routes two multiplexed DVO ports that are each capable of driving up to a 200 MHz pixel clock to the PCI Express x16 connector. The DVO ports can be paired for a dual channel configuration to support up to a 400 MHz pixel clock. When an ADD2/ADD2+ card is detected, the Intel GMA950 graphics controller is enabled and the PCI Express x16 connector is configured for DVO mode. DVO mode enables the DVO ports to be accessed by the ADD2/ADD2+ card. An ADD2/ADD2+ card can either be configured to support simultaneous display with the primary VGA display or can be configured to support dual independent display as an extended desktop configuration with different color depths and resolutions. ADD2/ADD2+ cards can be designed to support the following configurations: • • • • • • TV-Out (composite video) Transition Minimized Differential Signaling (TMDS) for DVI 1.0 Low Voltage Differential Signaling (LVDS) Single device operating in dual channel mode VGA output HDTV output 1.5.1.4 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 15 1.5.2 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. 20 For information about Refer to The location of the USB connectors on the back panel Figure 8, page 45 The location of the front panel USB headers Figure 9, page 46 Product Description 1.5.3 IDE Support The board provides five IDE interface connectors: • • One parallel ATA IDE connector that supports two devices Four serial ATA IDE connectors that support one device per connector 1.5.3.1 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 46 1.5.3.2 Serial ATA Interfaces The ICH7’s Serial ATA controller offers four 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 four 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 2000 operating systems. 21 Intel Desktop Board D945GCNL Technical Product Specification NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors 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 46 1.5.4 Real-Time Clock, CMOS SRAM, and Battery 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. 1.6 PCI Express* Connectors The board provides the following PCI Express connectors: • • One PCI Express x16 connector supporting simultaneous transfer speeds up to 4 GBytes/sec of peak bandwidth per direction and up to 8 GBytes/sec concurrent bandwidth One PCI Express x1 connector.

The board has several hardware management features, including the following: • • • Chassis intrusion detection Fan monitoring and control (through the SMSC 5127 I/O Controller) Thermal and voltage monitoring 1.10.1 Hardware Monitoring and Fan Control ASIC The features of the hardware monitoring and fan control ASIC include: • • • • • Internal ambient temperature sensor Two remote thermal diode sensors for direct monitoring of processor temperature and ambient temperature sensing Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.5 V, and +VCCP) to detect levels above or below acceptable values Thermally monitored closed-loop fan control, for all three fans, that can adjust the fan speed or switch the fans on or off as needed SMBus interface For information about Refer to The location of the fan headers and sensors for thermal monitoring Figure 5, page 29 1.10.2 Chassis Intrusion and Detection The board supports a chassis security feature that detects if the chassis cover is removed. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion header. When the chassis cover is removed, the mechanical switch is in the closed position. 1.10.3 Fan Monitoring Fan monitoring can be implemented using third-party software. The level of monitoring and control is dependent on the I/O controller used with the board. 28 For information about Refer to The functions of the fan headers Section 1.11.2.2, page 33 Product Description 1.10.4 Thermal Monitoring Figure 5 shows the location of the sensors and fan headers.

Thermal Sensors and Fan Headers 29 Intel Desktop Board D945GCNL Technical Product Specification 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 headers ⎯ LAN wake capabilities ⎯ Instantly Available PC technology ⎯ Wake from USB ⎯ Wake from PS/2 devices ⎯ Power Management Event signal (PME#) wake-up support 1.11.1 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 this 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 7 on page 32) Support for a front panel power and sleep mode switch Table 5 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 5. Effects of Pressing the Power Switch 30 If the system is in this …and the power switch is state… pressed for …the system enters this state Off (ACPI G2/G5 – Soft off) Less than four seconds Power-on (ACPI G0 – working state) On (ACPI G0 – working state) Less than four seconds Soft-off/Standby (ACPI G1 – sleeping state) On (ACPI G0 – working state) More than four seconds Fail safe power-off (ACPI G2/G5 – Soft off) Sleep (ACPI G1 – sleeping state) Less than four seconds Wake-up (ACPI G0 – working state) Sleep (ACPI G1 – sleeping state) More than four seconds Power-off (ACPI G2/G5 – Soft off) Product Description 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 6 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 6.

Service can be performed safely. AC power is disconnected from the computer. Notes: 1. Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis’ power supply. 2. Dependent on the standby power consumption of wake-up devices used in the system. 1.11.1.2 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. Currently Intel Desktop Boards meet the new requirements. For information about ENERGY STAR requirements and recommended configurations Refer to http://www.intel.com/go/energystar 31 Intel Desktop Board D945GCNL Technical Product Specification 1.11.1.3 Wake-up Devices and Events Table 7 lists the devices or specific events that can wake the computer from specific states. Table 7. Wake-up Devices and Events These devices/events can wake up the computer… …from this state LAN S1, S3, S4, S5 (Note) Modem (back panel Serial Port A) S1, S3 PME# signal S1, S3, S4, S5 (Note) Power switch S1, S3, S4, S5 PS/2 devices S1, S3 RTC alarm S1, S3, S4, S5 USB S1, S3 WAKE# signal S1, S3, S4, S5 Note: 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 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. 1.11.2 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 Wake from PS/2 keyboard PME# signal wake-up support WAKE# signal wake-up support LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. 32 Product Description NOTE The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support. 1.11.2.1 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 46 The signal names of the main power connector Table 20, page 49 1.11.2.2 Fan Headers The function/operation of the fan headers is as follows: • • • • • The fans are on when the board is in the S0 or S1 state. The fans are off when the board is off or in the S3, S4, or S5 state. Each fan header is wired to a fan tachometer input of the hardware monitoring and fan control ASIC. All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. All fan headers have a +12 V DC connection. For information about Refer to The location of the fan headers Figure 9, page 46 The location of the fan headers and sensors for thermal monitoring Figure 5, page 29 The signal names of the processor fan header Table 18, page 48 The signal names of the chassis fan headers Table 19, page 48 33 Intel Desktop Board D945GCNL Technical Product Specification 1.11.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for 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 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 Express WAKE# signal The PCI Conventional bus PME# signal for PCI 2.3 compliant LAN designs The onboard LAN subsystem 1.11.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, the +5 V standby line for 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-toRAM) 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 7 on page 32 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, PCI Express add-in cards, and drivers. 1.11.2.5 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 states. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 34 Product Description 1.11.2.6 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.11.2.7 PME# Signal Wake-up Support When the PME# signal on the PCI Conventional bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS). 1.11.2.8 WAKE# Signal Wake-up Support When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state. 1.11.2.9 +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. Figure 6.

The PIC is supported in Windows 98 SE and Windows ME and uses the first 16 interrupts. The APIC is supported in Windows 2000 and Windows XP and supports a total of 24 interrupts. Table 12 lists the interrupts. Table 12.

Default, but can be changed to another IRQ. 2. Available in APIC mode only. 42 Technical Reference 2.6 PCI Conventional Interrupt Routing Map This section describes interrupt sharing and how the interrupt signals are connected between the PCI Conventional bus connectors and onboard PCI Conventional devices. The PCI Conventional specification describes how interrupts can be shared between devices attached to the PCI Conventional bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices. In some special cases where maximum performance is needed from a device, a PCI Conventional device should not share an interrupt with other PCI Conventional devices. Use the following information to avoid sharing an interrupt with a PCI Conventional add-in card. PCI Conventional devices are categorized as follows to specify their interrupt grouping: • • • INTA: By default, all add-in cards that require only one interrupt are in this category. For almost all cards that require more than one interrupt, the first interrupt on the card is also classified as INTA. INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is classified as INTB. (This is not an absolute requirement.) INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a fourth interrupt is classified as INTD. The ICH7 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI Conventional interrupt sources either onboard or from a PCI Conventional add-in card connect to one of these PIRQ signals. Some PCI Conventional interrupt sources are electrically tied together on the board and therefore share the same interrupt. Table 13 shows an example of how the PIRQ signals are routed. Table 13. PCI Interrupt Routing Map ICH7 PIRQ Signal Name PCI Interrupt Source PIRQA PIRQB PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH PCI bus connector 1 INTD INTA INTB INTC PCI bus connector 2 INTA INTB INTC INTD ICH7 LAN INTA NOTE In PIC mode, the ICH7 can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal. Refer to Table 12 for the allocation of PIRQ lines to IRQ signals in APIC mode. PCI interrupt assignments to the USB ports, Serial ATA ports, and PCI Express ports are dynamic. 43 Intel Desktop Board D945GCNL Technical Product Specification 2.7 Connectors and Headers CAUTION Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2. 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. This section describes the board’s connectors and headers. The connectors and headers can be divided into these groups: • • 44 Back panel connectors (see page 45) Component-side connectors and headers (see page 46) Technical Reference 2.7.1 Back Panel Connectors Figure 8 shows the location of the back panel connectors.

Figure 13. Board Dimensions 56 Technical Reference 2.10 Electrical Considerations 2.10.1 Power Supply Considerations CAUTION The +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. 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. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the indicated parameters of the ATX form factor specification. • The potential relation between 3.3 VDC and +5 VDC power rails • The current capability of the +5 VSB line • All timing parameters • All voltage tolerances For example, for a system consisting of a supported 65 W processor (see section 1.3 on page 15 for a list of supported processors), 1 GB DDR2 RAM, one hard disk drive, one optical drive, and all board peripherals enabled, the minimum recommended power supply is 300 W. Table 27 lists the recommended power supply current values. Table 27.

The total +5 V current draw for add-in boards for a fully loaded board (all three expansion slots filled) must not exceed 6 A. 58 Technical Reference 2.11 Thermal Considerations CAUTION A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heatsink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area. 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 2.13. 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 (item A in Figure 14) can reach a temperature of up to 85 oC in an open chassis. 59 Intel Desktop Board D945GCNL Technical Product Specification Figure 14 shows the locations of the localized high temperature zones.

BIOS Security Features .................................................................... 63 64 64 65 66 67 67 69 70 Introduction The boards use 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, 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 NL94510J.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the processor 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. Maintenance Main Advanced Security Power Boot Exit NOTE The maintenance menu is displayed only when the Desktop Board is in configure mode. Section 2.8 on page 54 shows how to put the Desktop Board in configure mode. 63 Intel Desktop Board D945GCNL Technical Product Specification Table 31 lists the BIOS Setup program menu features.

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. 64 Overview of BIOS Features 3.3.2 PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The interface also supports second-generation SATA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: • • • An ATA-66/100 peripheral device An ATA-66/100 compatible cable ATA-66/100 operating system device drivers NOTE Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive. 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, such as Windows NT*, 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. 65 Intel Desktop Board D945GCNL Technical Product Specification 3.5 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 1.44 MB diskette, or a CD-ROM, or from the file location on the Web. Intel® Flash Memory update utility, which requires creation of a boot diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette 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 The Intel World Wide Web site Section 1.2, page 15 3.5.1 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. 3.5.2 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 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. 66 For information about Refer to The Intel World Wide Web site Section 1.2, page 15 Overview of BIOS Features 3.6 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. 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. 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. To install an operating system that supports USB, follow the operating system’s installation instructions. 3.7 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, 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. The fourth device is disabled. 3.7.1 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 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. 3.7.2 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. 67 Intel Desktop Board D945GCNL Technical Product Specification 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 33 lists the boot device menu options. Table 33. Boot Device Menu Options 68 Boot Device Menu Function Keys Description <↑> or <↓> Selects a default boot device <Enter> Exits the menu, saves changes, and boots from the selected device <Esc> Exits the menu without saving changes Overview of BIOS Features 3.8 Adjusting Boot Speed These factors affect system boot speed: • • Selecting and configuring peripherals properly Optimized BIOS boot parameters 3.8.1 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. 3.8.2 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. Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes. 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). 69 Intel Desktop Board D945GCNL Technical Product Specification 3.9 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 34 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen. Table 34.

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. 71 Intel Desktop Board D945GCNL Technical Product Specification 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 37 lists the Port 80h POST code ranges Table 38 lists the Port 80h POST codes themselves Table 39 lists the Port 80h POST sequence NOTE In the tables listed above, all POST codes and range values are listed in hexadecimal. Table 37.
