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. • Flex mode. This mode provides the most flexible performance characteristics. The bottommost DRAM memory (the memory that is lowest within the system memory map) is mapped to dual channel operation; the topmost DRAM memory (the memory that is nearest to the 4 GB address space limit), if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To use flex mode, it is necessary to populate both channels. For information about… Refer to: Memory Configuration Examples http://www.intel.com/support/motherboards/desktop/sb/cs- 011965.htm 16 Product Description Figure 3 illustrates the memory channel and DIMM configuration. Figure 3. Memory Channel Configuration and DIMM Configuration NOTE Regardless of the memory configuration used (dual channel, single channel, or flex mode), DIMM 0 of Channel A must always be populated. 17 Intel Desktop Board DG41KR Technical Product Specification ® 1.6 Intel G41 Express Chipset The Intel G41 Express chipset consists of the following devices: • Intel 82G41 Graphics and 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. The chipset supports the following features: • Onboard graphics • Dynamic Video Memory Technology • USB • Serial ATA • Parallel IDE For information about Refer to The Intel G41 Express chipset http://www.intel.com/products/desktop/chipsets/index.htm Resources used by the chipset Chapter 2 ® 1.6.1 Intel G41 Graphics Subsystem The Intel G41 Express chipset contains two separate, mutually exclusive graphics options. Either the Intel Graphics Media Accelerator X4500 (Intel GMA X4500) graphics controller (contained within the 82G41 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 Intel GMA X4500 graphics controller is disabled. ® 1.6.1.1 Intel Graphics Media Accelerator X4500 Graphics Controller The Intel GMA X4500 graphics controller features the following: • High quality texture engine ⎯ DirectX10* and OpenGL* 2.0 compliant ⎯ Shader Model 4.0 • 3D Graphics Rendering enhancements ⎯ 1.6 dual texture GigaPixel/s max fill rate ⎯ 16-bit and 32-bit color ⎯ Vertex cache • Video ⎯ High-definition content at up to 1080p resolution ⎯ Dynamic Video Memory Technology (DVMT) 5.0 uses system memory depending on the operating system and the amount of memory installed 18 Product Description • Display ⎯ Supports digital and analog displays up to 2048 x 1536 at 75 Hz refresh (QXGA); also supports 1920 x 1080 resolution for full high-definition video playback quality ⎯ Dual independent display support 1.6.1.2 Dynamic Video Memory Technology (DVMT 5.0) DVMT enables enhanced graphics and memory performance through highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. The amount of system memory allocated to DVMT varies depending on the amount of total system memory installed as well as the operating system being used. For Windows Vista, a minimum of 128 MB can be allocated to DVMT and a maximum of over 2 GB can be allocated to DVMT with the correct amount of memory 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 The video modes supported by this board are based on the Extended Display Identification Data (EDID) modes of the monitor to which the system is connected. Standard monitors are assumed. 1.6.1.4 High-Definition Multimedia Interface* (HDMI*) The HDMI port supports standard, enhanced, or high-definition video, plus multi- channel digital audio on a single cable. It is compatible with all ATSC and DVB HDTV standards and supports 8-channel digital audio. The HDMI port is compliant with the HDMI 1.3 specification. Depending on the type of add-in card installed in the PCI Express x16 connector, the HDMI port will behave as described in Table 4. Table 4. HDMI Port Status Conditions PCI Express x16 Connector Status HDMI Port Status No add-in card installed Enabled Non-video PCI Express x1 add-in card installed Disabled PCI Express x4, x8, or x16 add-in card installed Disabled ADD2 or MEC/ADD2+ card installed Disabled 19 Intel Desktop Board DG41KR Technical Product Specification 1.6.1.5 Analog Display (VGA) The VGA port supports analog displays. The maximum supported resolution is 2048 x 1536 (QXGA) at a 75 Hz refresh rate. 1.6.1.6 Advanced Digital Display (ADD2/MEC/ADD2+) Card Support The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a 270 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC/ADD2+ card is detected, the Intel GMA X4500 graphics controller is enabled and the PCI Express x16 connector is configured for SDVO mode. SDVO mode enables the SDVO ports to be accessed by the ADD2/MEC/ADD2+ card. An ADD2/MEC/ADD2+ card can either be configured to support simultaneous display or can be configured to support dual independent display as an extended desktop configuration with different color depths and resolutions with DVI analog output only. ADD2/MEC/ADD2+ cards can be designed to support the following configurations: • Low Voltage Differential Signaling (LVDS) • Single device operating in dual channel mode • HDTV output • HDMI support (when used with the HD Audio Link header) 1.6.1.7 PCI Express x16 Graphics The GMCH also supports add-in discrete graphics card via the PCI Express graphics connector. • PCI Express 1.1 x16: ⎯ Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). Maximum theoretical bandwidth on interface of 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. For information about Refer to PCI Express technology http://www.pcisig.com 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 stacked back panel connectors • Four ports are routed to two separate front panel USB headers For information about Refer to The location of the USB connectors on the back panel Figure 9, page 43 The location of the front panel USB headers Figure 10, page 44 20 Product Description 1.6.3 Serial ATA Interfaces The board’s Serial ATA controller offers four independent Serial ATA ports with a theoretical maximum transfer rate of 3 Gbits/s 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 operating system. 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 connectors Figure 10, page 44 21 Intel Desktop Board DG41KR Technical Product Specification 1.7 Parallel IDE Controller The 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/s. • Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/s. • ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/s. 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 ATA-100 logic can achieve read transfer rates up to 100 MB/s and write transfer rates up to 88 MB/s. 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. 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.

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 9 on page 32) • Support for a front panel power and sleep mode switch Table 7 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 7. 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) 30 Product Description 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 8 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 9. 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 (Note 2) PS/2 devices S1, S3, S4, S5 RTC alarm S1, S3, S4, S5 Serial port S1, S3 USB S1, S3 WAKE# signal S1, S3, S4, S5 Notes: 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. 2. S4 or S5 wake from PS/2 is disabled by default. 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. 32 Product Description 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# signal wake-up support • Wake from PS/2 devices • Wake from serial port LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. NOTE The use of Wake from USB 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 10, page 44 The signal names of the main power connector Table 20, page 49 33 Intel Desktop Board DG41KR Technical Product Specification 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 processor fan header is wired to a fan tachometer input. The rear fan header has independent tachometer input to the hardware monitoring and fan control device. All fan headers support closed-loop fan control that can adjust the fan speed according to thermal conditions. • All fan headers have a +12 V DC connection. For information about Refer to The locations of the fan headers and thermal sensors Figure 6, page 29 The signal names of the processor fan header Table 16, page 47 Table 15, page 46 The signal names of the chassis fan header 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 Express WAKE# signal • The PCI bus PME# signal for PCI 2.3 compliant LAN designs • The onboard LAN subsystem 34 Product Description 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 9 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 and drivers. 1.13.2.5 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 state. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB and support in the operating system. 1.13.2.6 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). 1.13.2.7 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. 1.13.2.8 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1, S3, S4, and S5 state. NOTE PS/2 wake from S4 and S5 states via the special keyboard key (the keyboard power- on key) must have the keyboard power-on enable/disable option in the BIOS enabled. 35 Intel Desktop Board DG41KR Technical Product Specification 1.13.2.9 Wake from Serial Port Serial port activity wakes the computer from an ACPI S1 or S3 state. 1.13.2.10 +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 7 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. Failure to do so could damage the board and any attached devices. Figure 7. Location of the Standby Power Indicator LED 36 Product Description 1.13.3 ENERGY STAR*, e-Standby, and EuP Compliance The US Department of Energy and the US Environmental Protection Agency have continually revised the ENERGY STAR requirements. Intel has worked directly with these two governmental agencies in the definition of the new requirements. This Desktop Board meets the ENERGY STAR Program for Computers: Version 5.0 Category A requirements. For information about ENERGY STAR requirements and recommended configurations, go to http://www.intel.com/go/energystar. The Desktop Board also meets the following international requirements: • Republic of Korea e-Standby program • European Union Energy using Products (EuP) directive 37 Intel Desktop Board DG41KR Technical Product Specification 38 2 Technical Reference 2.1 Memory Map 2.1.1 Addressable Memory The board utilizes 4 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 4 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following: • BIOS/SPI Flash (16 Mbits) • Local APIC (19 MB) • Direct Media Interface (40 MB) • Front side bus interrupts (17 MB) • PCI Express configuration space (256 MB) • GMCH base address registers, internal graphics ranges, PCI Express ports (up to 512 MB) • Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCI Express add-in cards • Base graphics memory support (1 MB or 8 MB) NOTE System resources and hardware (such as PCI and PCI Express*) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1 GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system. 39 Intel Desktop Board DG41KR Technical Product Specification The amount of installed memory that can be used will vary based on add-in cards and BIOS settings. Figure 8 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses. Figure 8.

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. Furthermore, improper connection of USB header signal wire connectors may eventually overload the overcurrent protection and cause damage to the board. 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 43) • Component-side connectors and headers (see page 44) 42 Technical Reference 2.2.1 Back Panel Connectors Figure 9 shows the locations of the back panel connectors.

The maximum theoretical bandwidth on the interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. • PCI Express x1: one PCI Express x1 connector. The x1 interface supports simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per direction and up to 500 MB/sec concurrent bandwidth. • PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card connectors. Note the following considerations for the PCI Conventional bus connectors: • All of the PCI Conventional bus connectors are bus master capable. • SMBus signals are routed to all PCI Conventional bus connectors. 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. 48 Technical Reference 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. • Processor core power – a 2 x 2 connector.

Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged. Figure 13 shows the location of the jumper block. The jumper determines the BIOS Setup program’s mode. Table 25 lists the jumper settings for the three modes: normal, configure, and recovery. When the 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. Figure 13. Location of the Jumper Block 53 Intel Desktop Board DG41KR Technical Product Specification Table 25. BIOS Setup Configuration Jumper Settings Function/Mode Jumper Setting Configuration The BIOS uses current configuration information and Normal 1-2 passwords for booting. After the POST runs, Setup runs automatically. The Configure 2-3 maintenance menu is displayed. The BIOS attempts to recover the BIOS configuration. See Recovery None Section 3.7 for more information on BIOS recovery. 54 Technical Reference 2.4 Mechanical Considerations 2.4.1 Form Factor The board is designed to fit into an ATX-form-factor chassis. Figure 14 illustrates the mechanical form factor of the board. Dimensions are given in inches [millimeters]. The outer dimensions are 9.60 inches by 8.60 inches [243.84 millimeters by 218.44 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification. Figure 14. Board Dimensions 55 Intel Desktop Board DG41KR Technical Product Specification 2.5 Electrical Considerations 2.5.1 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 1.4 on page 14 for a list of supported processors), 1 GB DDR3 RAM, one hard disk drive, one optical drive, and all board peripherals enabled, the minimum recommended power supply is 300 W. Table 26 lists the recommended power supply current values. Table 26. Recommended Power Supply Current Values 3.3 V 5 V 12 V1 12 V2 -12 V 5 VSB Output Voltage 15 A 15 A 10 A 10 A 0.3 A 3.0 A Current 56 Technical Reference 2.5.2 Fan Header Current Capability CAUTION The processor fan must be connected to the processor fan header, not to a chassis fan header. Connecting the processor fan to a chassis fan header may result in onboard component damage that will halt fan operation. Table 27 lists the current capability of the fan headers. Table 27. Fan Header Current Capability Fan Header Maximum Available Current Processor fan 2.0 A Rear chassis fan 1.5 A Front chassis fan 1.5 A 2.5.3 Add-in Board Considerations The board is designed to provide 2 A (average) of +5 V current for each add-in board. The total +5 V current draw for add-in boards for a fully loaded board (both expansion slots filled and the PCI Express x16 connector filled) must not exceed 8 A. 2.6 Thermal Considerations CAUTION Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have been tested with Intel desktop boards please refer to the following website: http://www3.intel.com/cd/channel/reseller/asmo-na/eng/tech_reference/53211.htm All responsibility for determining the adequacy of any thermal or system design remains solely with the 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. 57 Intel Desktop Board DG41KR Technical Product Specification 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 15) can reach a temperature of up to 95 C in an open chassis. Figure 15 shows the locations of the localized high temperature zones. Item Description A Processor voltage regulator area B Processor C Intel 82G41 GMCH D Intel 82801GB (ICH7) Figure 15. Localized High Temperature Zones 58 Technical Reference Table 28 provides maximum case temperatures for the board components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board. Table 28.

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 KRG4110H.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. Section 2.3 on page 53 shows how to put the board in configure mode. 61 Intel Desktop Board DG41KR Technical Product Specification Table 30 lists the BIOS Setup program menu features. Table 30.

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. 62 Overview of BIOS Features 3.3.2 PCI IDE 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. 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 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. 63 Intel Desktop Board DG41KR 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. 64 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/s b/CS-022312.htm. 3.6.1 Language Support The BIOS Setup program and help messages are supported in US English, French, Spanish, and German. 65 Intel Desktop Board DG41KR Technical Product Specification 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 Toolkit or Intel Integrator Assistant that are 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. For information about Refer to Intel Integrator Toolkit http://developer.intel.com/design/motherbd/software/itk/ ® Additional Intel software tools http://developer.intel.com/products/motherboard/DG41KR/tools.htm and http://developer.intel.com/design/motherbd/software.htm 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 32 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 32. 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 Legacy diskette drive (with a 1.44 MB diskette) connected to the No legacy diskette drive interface For information about Refer to BIOS recovery http://support.intel.com/support/motherboards/desktop/ sb/CS-023360.htm 66 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. The fourth device is disabled. 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 33 lists the boot device menu options. Table 33. 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 67 Intel Desktop Board DG41KR 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” in less than eight seconds that minimizes 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). 68 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 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 37 lists the error messages and provides a brief description of each. Table 37. 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. 72 Error Messages and Beep Codes 4.5 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 38 lists the Port 80h POST code ranges • Table 39 lists the Port 80h POST codes themselves • Table 40 lists the Port 80h POST sequence NOTE In the tables listed above, all POST codes and range values are listed in hexadecimal.
