Intel Desktop Board DG41RQ Technical Product Specification1.5.1 Memory ConfigurationsThe Intel 82G41 GMCH supports the following types of memory organization:• Dual channel (Interleaved) mode. This mode offers the highest throughput forreal world applications. Dual channel mode is enabled when the installed memorycapacities of both DIMM channels are equal. Technology and device width can varyfrom one channel to the other but the installed memory capacity for each channelmust be equal. If different speed DIMMs are used between channels, the slowestmemory timing will be used.• Single channel (Asymmetric) mode. This mode is equivalent to single channelbandwidth operation for real world applications. This mode is used when only asingle DIMM is installed or the memory capacities are unequal. Technology anddevice width can vary from one channel to the other. If different speed DIMMs areused 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 systemmemory map) is mapped to dual channel operation; the topmost DRAM memory(the memory that is nearest to the 8 GB address space limit), if any, is mapped tosingle channel operation. Flex mode results in multiple zones of dual and singlechannel operation across the whole of DRAM memory. To use flex mode, it isnecessary to populate both channels.For information about…Memory Configuration ExamplesRefer to:http://www.intel.com/support/motherboards/desktop/sb/cs-011965.htm16

Product DescriptionFigure 3 illustrates the memory channel and DIMM configuration.Figure 3. Memory Channel Configuration and DIMM Configuration INTEGRATOR’S NOTERegardless of the memory configuration used (dual channel, single channel, or flexmode), DIMM 0 of Channel A must always be populated.17

Intel Desktop Board DG41RQ Technical Product Specification1.6 Intel ® G41 Express ChipsetThe Intel G41 Express chipset consists of the following devices:• Intel 82G41 Graphics and Memory Controller Hub (GMCH) with Direct MediaInterface (DMI) interconnect• Intel 82801GB I/O Controller Hub (ICH7) with DMI interconnectThe GMCH component provides interfaces to the CPU, memory, PCI Express, and theDMI interconnect. The component also provides integrated graphics capabilitiessupporting 3D, 2D, and display capabilities. The ICH7 is a centralized controller forthe board’s I/O paths.The chipset supports the following features:• Onboard graphics• Dynamic Video Memory Technology• USB• Serial ATA• Parallel IDEFor information aboutRefer toThe Intel G41 Express chipsethttp://www.intel.com/products/desktop/chipsets/index.htmResources used by the chipset Chapter 21.6.1 Intel G41 Graphics SubsystemThe Intel G41 Express chipset contains two separate, mutually exclusive graphicsoptions. Either the Intel Graphics Media Accelerator X4500 (Intel GMA X4500)graphics controller (contained within the 82G41 GMCH) is used, or a PCI Express x16add-in card can be used. When a PCI Express x16 add-in card is installed, the IntelGMA X4500 graphics controller is disabled.1.6.1.1 Intel ® Graphics Media Accelerator X4500 GraphicsControllerThe 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/sec max fill rate⎯ 16-bit and 32-bit color⎯ Vertex cache• Video⎯ Hi-Definition content at up to 1080p resolution⎯ Dynamic Video Memory Technology (DVMT) 5.0 uses system memorydepending on the operating system and the amount of memory installed18

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 videoplayback quality⎯ Dual independent display support1.6.1.2 Dynamic Video Memory Technology (DVMT 5.0)DVMT enables enhanced graphics and memory performance through highly efficientmemory utilization. DVMT ensures the most efficient use of available system memoryfor maximum 2-D/3-D graphics performance. The amount of system memoryallocated to DVMT varies depending on the amount of total system memory installedas well as the operating system being used. For Windows Vista, a minimum of 128 MBcan be allocated to DVMT and a maximum of over 2 GB can be allocated to DVMT withthe correct amount of memory installed. DVMT returns system memory back to theoperating system when the additional system memory is no longer required by thegraphics subsystem.DVMT will always use a minimal fixed portion of system physical memory (as set in theBIOS Setup program) for compatibility with legacy applications. An example of thiswould be when using VGA graphics under DOS. Once loaded, the operating systemand graphics drivers allocate additional system memory to the graphics buffer asneeded for performing graphics functions. NOTEThe use of DVMT requires operating system driver support.1.6.1.3 Configuration ModesThe video modes supported by this board are based on the Extended DisplayIdentification Data (EDID) modes of the monitor to which the system is connected.Standard monitors are assumed.1.6.1.4 Advanced Digital Display (ADD2/MEC/ADD2+) CardSupportThe GMCH routes two multiplexed SDVO ports that are each capable of driving up to a270 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 PCIExpress x16 connector is configured for SDVO mode. SDVO mode enables the SDVOports to be accessed by the ADD2/MEC/ADD2+ card. An ADD2/MEC/ADD2+ card caneither be configured to support simultaneous display or can be configured to supportdual independent display as an extended desktop configuration with different colordepths and resolutions with DVI analog output only. ADD2/MEC/ADD2+ cards can bedesigned 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)19

Intel Desktop Board DG41RQ Technical Product Specification1.6.1.5 PCI Express x16 GraphicsThe GMCH supports add-in graphics cards via the PCI Express connector.The PCI Express, revision 1.1, x16 interface supports the PCI Express GEN1 frequencyof 1.25 GHz resulting in a data transfer rate of 2.5 Gb/s each direction (500 MB/stotal). This provides a maximum theoretical bandwidth on the interface of 4 GB/s ineach direction simultaneously, for an aggregate bandwidth of 8 GB/s when theinterface is operating in x16 mode.For information aboutPCI Express technologyRefer tohttp://www.pcisig.com1.6.2 USBThe board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and usesUHCI- and EHCI-compatible drivers.The ICH7 provides the USB controller for all ports. The port arrangement is asfollows:• Four ports are implemented with stacked back panel connectors• Four ports are routed to two separate front panel USB headersFor information aboutRefer toThe location of the USB connectors on the back panel Figure 9, page 43The location of the front panel USB headers Figure 10, page 4420

Product Description1.6.3 Serial ATA InterfacesThe board’s Serial ATA controller offers four independent Serial ATA ports with atheoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installedon each port for a maximum of four Serial ATA devices. A point-to-point interface isused for host to device connections, unlike Parallel ATA IDE which supports amaster/slave configuration and two devices per channel.For compatibility, the underlying Serial ATA functionality is transparent to theoperating system. The Serial ATA controller can operate in both legacy and nativemodes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14and 15). In Native mode, standard PCI Conventional bus resource steering is used.Native mode is the preferred mode for configurations using the Windows* XPoperating system. NOTEMany Serial ATA drives use new low-voltage power connectors and require adapters orpower supplies equipped with low-voltage power connectors.For more information, see: http://www.serialata.org/For information aboutRefer toThe location of the Serial ATA connectors Figure 10, page 4421

Intel Desktop Board DG41RQ Technical Product Specification1.7 Parallel IDE ControllerThe Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. TheParallel 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 to16 MB/sec.• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling andtransfer rates of up to 33 MB/sec.• ATA-66: DMA protocol on IDE bus supporting host and target throttling andtransfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and isdevice driver compatible.• ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100logic can achieve read transfer rates up to 100 MB/sec and write transfer rates upto 88 MB/sec. NOTEATA-66 and ATA-100 are faster timings and require a specialized cable to reducereflections, 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 ExtendedCylinder Head Sector (ECHS) translation modes. The drive reports the transfer rateand translation mode to the BIOS.For information aboutRefer toThe location of the Parallel ATA IDE connector Figure 10, page 4422

Product Description1.8 Real-Time Clock SubsystemA coin-cell battery (CR2032) powers the real-time clock and CMOS memory. Whenthe computer is not plugged into a wall socket, the battery has an estimated life ofthree years. When the computer is plugged in, the standby current from the powersupply extends the life of the battery. The clock is accurate to ± 13 minutes/year at25 ºC with 3.3 VSB applied. NOTEIf the battery and AC power fail, custom defaults, if previously saved, will be loadedinto CMOS RAM at power-on.When the voltage drops below a certain level, the BIOS Setup program settings storedin CMOS RAM (for example, the date and time) might not be accurate. Replace thebattery with an equivalent one.

S4 or S5 wake from PS/2 is disabled by default. NOTEThe use of these wake-up events from an ACPI state requires an operating systemthat provides full ACPI support. In addition, software, drivers, and peripherals mustfully support ACPI wake events.33

Intel Desktop Board DG41RQ Technical Product Specification1.13.2 Hardware SupportCAUTIONEnsure that the power supply provides adequate +5 V standby current if LAN wakecapabilities and Instantly Available PC technology features are used. Failure to do socan damage the power supply. The total amount of standby current required dependson 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 devices• PME# signal wake-up support• WAKE# signal wake-up supportLAN wake capabilities and Instantly Available PC technology require power from the+5 V standby line. NOTEThe use of Wake from USB from an ACPI state requires an operating system thatprovides full ACPI support.1.13.2.1 Power ConnectorATX12V-compliant power supplies can turn off the system power through systemcontrol. When an ACPI-enabled system receives the correct command, the powersupply removes all non-standby voltages.When resuming from an AC power failure, the computer returns to the power state itwas in before power was interrupted (on or off). The computer’s response can be setusing the Last Power State feature in the BIOS Setup program’s Boot menu.For information aboutRefer toThe location of the main power connector Figure 10, page 44The signal names of the main power connector Table 21, page 5034

Product Description1.13.2.2 Fan HeadersThe 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 headerhas independent tachometer input to the hardware monitoring and fan controldevice. All fan headers support closed-loop fan control that can adjust the fanspeed according to thermal conditions.• All fan headers have a +12 V DC connection.For information aboutRefer toThe locations of the fan headers and thermal sensors Figure 6, page 30The signal names of the processor fan header Table 14, page 47The signal names of the chassis fan header Table 13, page 471.13.2.3 LAN Wake CapabilitiesCAUTIONFor LAN wake capabilities, the +5 V standby line from the power supply must becapable of providing adequate +5 V standby current. Failure to provide adequatestandby current when implementing LAN wake capabilities can damage the powersupply.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 MediaIndependent Interface. Upon detecting a Magic Packet* frame, the LAN subsystemasserts a wake-up signal that powers up the computer. Depending on the LANimplementation, the board supports LAN wake capabilities with ACPI in the followingways:• The PCI Express WAKE# signal• The PCI bus PME# signal for PCI 2.3 compliant LAN designs• The onboard LAN subsystem35

Intel Desktop Board DG41RQ Technical Product Specification1.13.2.4 Instantly Available PC TechnologyCAUTIONFor Instantly Available PC technology, the +5 V standby line from the power supplymust be capable of providing adequate +5 V standby current. Failure to provideadequate standby current when implementing Instantly Available PC technology candamage 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 (thepower supply is off, and the front panel LED is amber if dual colored, or off if singlecolored.) When signaled by a wake-up device or event, the system quickly returns toits last known wake state. Table 8 on page 33 lists the devices and events that canwake the computer from the S3 state.The board supports the PCI Bus Power Management Interface Specification. Add-inboards that also support this specification can participate in power management andcan be used to wake the computer.The use of Instantly Available PC technology requires operating system support andPCI 2.3 compliant add-in cards and drivers.1.13.2.5 Wake from USBUSB bus activity wakes the computer from ACPI S3 state. NOTEWake from USB requires the use of a USB peripheral that supports Wake from USB.1.13.2.6 Wake from PS/2 DevicesPS/2 device activity wakes the computer from an ACPI S1, S3, S4, and S5 state. NOTEPS/2 wake from S4 and S5 states via the special keyboard key (the keyboard poweronkey) must have the keyboard power-on enable/disable option in the BIOS enabled.1.13.2.7 PME# Signal Wake-up SupportWhen the PME# signal on the PCI bus is asserted, the computer wakes from an ACPIS1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).1.13.2.8 WAKE# Signal Wake-up SupportWhen the WAKE# signal on the PCI Express bus is asserted, the computer wakes froman ACPI S1, S3, S4, or S5 state.36

2 Technical Reference2.1 Memory Map2.1.1 Addressable MemoryThe board utilizes 8 GB of addressable system memory. Typically the address spacethat is allocated for PCI Conventional bus add-in cards, PCI Express configurationspace, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (totalsystem memory). On a system that has 8 GB of system memory installed, it is notpossible to use all of the installed memory due to system address space beingallocated for other system critical functions. These functions include the following:• BIOS/SPI Flash (8 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 to512 MB)• Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCIExpress add-in cards• Base graphics memory support (1 MB or 8 MB) NOTESystem resources and hardware (such as PCI and PCI Express*) require physicalmemory address locations that can reduce available addressable system memory. Thiscould result in a reduction of as much as 1 GB or more of physical addressablememory being available to the operating system and applications, depending on thesystem configuration and operating system.39

Intel Desktop Board DG41RQ Technical Product SpecificationThe amount of installed memory that can be used will vary based on add-in cards andBIOS settings.

3 Overview of BIOS Features3.1 IntroductionThe board uses an Intel BIOS that is stored in the Serial Peripheral Interface FlashMemory (SPI Flash) and can be updated using a disk-based program. The SPI Flashcontains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plugand Play support.The BIOS displays a message during POST identifying the type of BIOS and a revisioncode. The initial production BIOSs are identified as RQG4110H.86A.When the BIOS Setup configuration jumper is set to configure mode and the computeris powered-up, the BIOS compares the CPU version and the microcode version in theBIOS and reports if the two match.The BIOS Setup program can be used to view and change the BIOS settings for thecomputer. The BIOS Setup program is accessed by pressing the key after thePower-On Self-Test (POST) memory test begins and before the operating system bootbegins. The menu bar is shown below.Maintenance Main Advanced Security Power Boot Exit NOTEThe maintenance menu is displayed only when the board is in configure mode.Section 2.3 on page 54 shows how to put the board in configure mode.61

PCI devices may be onboard oradd-in cards. Autoconfiguration lets a user insert or remove PCI cards without havingto 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 systemresources. Any interrupts set to Available in Setup are considered to be available foruse by the add-in card.62

Overview of BIOS Features3.3.2 PCI IDE SupportThe IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPIcompliant 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 NOTEDo not connect an ATA device as a slave on the same IDE cable as an ATAPI masterdevice. For example, do not connect an ATA hard drive as a slave to an ATAPICD-ROM drive.3.4 System Management BIOS (SMBIOS)SMBIOS is a Desktop Management Interface (DMI) compliant method for managingcomputers in a managed network.The main component of SMBIOS is the Management Information Format (MIF)database, which contains information about the computing system and itscomponents. Using SMBIOS, a system administrator can obtain the system types,capabilities, operational status, and installation dates for system components. TheMIF database defines the data and provides the method for accessing this information.The BIOS enables applications such as third-party management software to useSMBIOS. 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 loggingNon-Plug and Play operating systems require an additional interface for obtaining theSMBIOS information. The BIOS supports an SMBIOS table interface for such operatingsystems. Using this support, an SMBIOS service-level application running on anon-Plug and Play operating system can obtain the SMBIOS information. Additionalboard information can be found in the BIOS under the Additional Information headerunder the Main BIOS page.63

Intel Desktop Board DG41RQ Technical Product Specification3.5 Legacy USB SupportLegacy USB support enables USB devices to be used even when the operatingsystem’s USB drivers are not yet available. Legacy USB support is used to access theBIOS Setup program, and to install an operating system that supports USB. Bydefault, 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 toenter and configure the BIOS Setup program and the maintenance menu.4. POST completes.5. The operating system loads. While the operating system is loading, USBkeyboards and mice are recognized and may be used to configure the operatingsystem. (Keyboards and mice are not recognized during this period if Legacy USBsupport was set to Disabled in the BIOS Setup program.)6. After the operating system loads the USB drivers, all legacy and non-legacy USBdevices are recognized by the operating system, and Legacy USB support from theBIOS is no longer used.7. Additional USB legacy feature options can be access by using Intel ® IntegratorToolkit.To install an operating system that supports USB, verify that Legacy USB support inthe BIOS Setup program is set to Enabled and follow the operating system’sinstallation instructions.64

Overview of BIOS Features3.6 BIOS UpdatesThe BIOS can be updated using either of the following utilities, which are available onthe Intel World Wide Web site:• Intel ® Express BIOS Update utility, which enables automated updating while in theWindows environment. Using this utility, the BIOS can be updated from a file on ahard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or fromthe file location on the Web.• Intel ® Flash Memory Update Utility, which requires booting from DOS. Using thisutility, the BIOS can be updated from a file on a hard disk, a USB drive (a flashdrive or a USB hard drive), or a CD-ROM.Both utilities verify that the updated BIOS matches the target system to preventaccidentally installing an incompatible BIOS. NOTEReview the instructions distributed with the upgrade utility before attempting a BIOSupdate.For information aboutBIOS update utilitiesRefer tohttp://support.intel.com/support/motherboards/desktop/sb/CS-022312.htm.3.6.1 Language SupportThe BIOS Setup program and help messages are supported in US English. Support forthree additional languages is currently in validation. Check the Intel website fordetails.65

Intel Desktop Board DG41RQ Technical Product Specification3.6.2 Custom Splash ScreenDuring POST, an Intel ® splash screen is displayed by default. This splash screen canbe 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 customsplash screen. NOTEIf you add a custom splash screen, it will share space with the Intel branded logo.For information aboutIntel Integrator ToolkitAdditional Intel ® software toolsRefer tohttp://developer.intel.com/design/motherbd/software/itk/http://developer.intel.com/products/motherboard/DG41RQ/tools.htmandhttp://developer.intel.com/design/motherbd/software.htm3.7 BIOS RecoveryIt is unlikely that anything will interrupt a BIOS update; however, if an interruptionoccurs, the BIOS could be damaged. Table 33 lists the drives and media types thatcan and cannot be used for BIOS recovery. The BIOS recovery media does not needto be made bootable.Table 33.

Overview of BIOS Features3.8 Boot OptionsIn the BIOS Setup program, the user can choose to boot from a diskette drive, harddrive, USB drive, USB flash drive, CD-ROM, or the network. The default setting is forthe diskette drive to be the first boot device, the hard drive second, and the ATAPICD-ROM third. The fourth device is disabled.3.8.1 CD-ROM BootBooting from CD-ROM is supported in compliance to the El Torito bootable CD-ROMformat specification. Under the Boot menu in the BIOS Setup program, ATAPICD-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 attemptto boot from the next defined drive.3.8.2 Network BootThe network can be selected as a boot device. This selection allows booting from theonboard LAN or a network add-in card with a remote boot ROM installed.Pressing the key during POST automatically forces booting from the LAN. Touse this key during POST, the User Access Level in the BIOS Setup program's Securitymenu must be set to Full.3.8.3 Booting Without Attached DevicesFor use in embedded applications, the BIOS has been designed so that after passingthe POST, the operating system loader is invoked even if the following devices are notpresent:• Video adapter• Keyboard• Mouse3.8.4 Changing the Default Boot Device During POSTPressing the key during POST causes a boot device menu to be displayed. Thismenu displays the list of available boot devices (as set in the BIOS setup program’sBoot Device Priority Submenu). Table 34 lists the boot device menu options.Table 34. Boot Device Menu OptionsBoot Device Menu Function Keys or DescriptionSelects a default boot deviceExits the menu, saves changes, and boots from the selecteddeviceExits the menu without saving changes67

Intel Desktop Board DG41RQ Technical Product Specification3.9 Adjusting Boot SpeedThese factors affect system boot speed:• Selecting and configuring peripherals properly• Optimized BIOS boot parameters3.9.1 Peripheral Selection and ConfigurationThe following techniques help improve system boot speed:• Choose a hard drive with parameters such as “power-up to data ready” less thaneight seconds, that minimize hard drive startup delays.• Select a CD-ROM drive with a fast initialization rate. This rate can influence POSTexecution time.• Eliminate unnecessary add-in adapter features, such as logo displays, screenrepaints, or mode changes in POST. These features may add time to the bootprocess.• Try different monitors. Some monitors initialize and communicate with the BIOSmore quickly, which enables the system to boot more quickly.3.9.2 BIOS Boot OptimizationsUse 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, thePOST does not first seek a diskette drive, which saves about one second from thePOST execution time.• In the Peripheral Configuration submenu, disable the LAN device if it will not beused. This can reduce up to four seconds of option ROM boot time. NOTEIt is possible to optimize the boot process to the point where the system boots soquickly 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 toa boot time that might be so fast that necessary logo screens and POST messagescannot be seen.This boot time may be so fast that some drives might be not be initialized at all. Ifthis condition should occur, it is possible to introduce a programmable delay rangingfrom three to 30 seconds (using the Hard Disk Pre-Delay feature of the AdvancedMenu in the Drive Configuration Submenu of the BIOS Setup program).68

Overview of BIOS Features3.10 BIOS Security FeaturesThe BIOS includes security features that restrict access to the BIOS Setup programand who can boot the computer. A supervisor password and a user password can beset for the BIOS Setup program and for booting the computer, with the followingrestrictions:• The supervisor password gives unrestricted access to view and change all theSetup options in the BIOS Setup program. This is the supervisor mode.• The user password gives restricted access to view and change Setup options in theBIOS Setup program. This is the user mode.• If only the supervisor password is set, pressing the key at the passwordprompt 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 thesupervisor password or the user password to access Setup. Users have access toSetup respective to which password is entered.• Setting the user password restricts who can boot the computer. The passwordprompt will be displayed before the computer is booted. If only the supervisorpassword is set, the computer boots without asking for a password. If bothpasswords are set, the user can enter either password to boot the computer.• For enhanced security, use different passwords for the supervisor and userpasswords.• Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to16 characters in length.Table 35 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 35.

Intel Desktop Board DG41RQ Technical Product Specification4.4 Port 80h POST CodesDuring the POST, the BIOS generates diagnostic progress codes (POST codes) to I/Oport 80h. If the POST fails, execution stops and the last POST code generated is leftat 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 aseven-segment display. NOTEThe 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 NOTEIn the tables listed above, all POST codes and range values are listed in hexadecimal.Table 38.
