1.5.1 Memory Configurations

The Intel 82G41 GMCH supports the following types of memory organization:

• Dual channel (Interleaved) mode. 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

Figure 3 illustrates the memory channel and DIMM configuration.

Product Description

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.

Intel Desktop Board DG41KR Technical Product Specification

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

G41 Express Chipset

1.6.1 Intel

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

G41 Graphics Subsystem

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

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 multichannel 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

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

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/

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.

1.13.1 ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the board requires an operating system that provides full ACPI support. ACPI features include:

• Plug and Play (including bus and device enumeration)

• Power management control of individual devices, add-in boards (some add-in

boards may require an ACPI-aware driver), video displays, and hard disk drives

• Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state

• A Soft-off feature that enables the operating system to power-off the computer

• Support for multiple wake-up events (see Table 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, dependi

ng on how ACPI is configured with an ACPI-aware operating system.

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 AC various system and power states.

2. S4 or S5 wake from PS/2 is disabled by default.

(Note 1)

(Note 2)

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.

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.

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.

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

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-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 9 on page 32 lists the devices and events that can wake the computer from the S3 state.

The board supports the PC 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.

I Bus Power Management Interface Specification. Add-in

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 poweron key) must have the keyboard power-on enable/disable option in the BIOS enabled.

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

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.

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 syst

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.

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.

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 voltage regulator area (shown in Figure 15) can reach a temperature of up to 95 an open chassis.

3 Overview of BIOS Features

3.1 Introduction

The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration utility, 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

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

The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. The menu bar is shown below.

Maintenance Main Advanced Security Power Boot Exit

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 8 Mbit (1024 KB) flash memory device.

3.3 Resource Configuration

3.3.1 PCI Autoconfiguration

The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card.

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.

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 Toolkit.

Integrator

To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions.

Overview of BIOS Features

3.6 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site:

• Intel

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

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 <F12> key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full.

3.8.3 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 <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.

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).

Overview of BIOS Features

3.10 BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions:

• The supervisor password gives unrestricted access to view and change all the

Setup options in the BIOS Setup program. This is the supervisor mode.

• The user password gives restricted access to view and change Setup options in the

BIOS Setup program. This is the user mode.

• If only the supervisor password is set, pressing the <Enter> key at the password

prompt of the BIOS Setup program allows the user restricted access to Setup.

• If both the supervisor and user passwords are set, users can enter either the

supervisor password or the user password to access Setup. Users have access to Setup respective to which password is entered.

• Setting the user password restricts who can boot the computer. The password

prompt will be displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer.

• For enhanced security, use different passwords for the supervisor and user

passwords.

• Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to

16 characters in length.

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

5.1.3.3 Lead Free Intel Desktop Board

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

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

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

Table 42 shows the various forms of the “Lead-Free 2 appears on the board and accompanying collateral.

Level Interconnect” mark as it
