Intel Desktop Board DX38BT Technical Product Specification
1.5 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.5 V with option to raise voltage to support higher performance DDR3 SDRAM
DIMMs
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
• 8 GB maximum total system memory. Refer to Section 2.1.1 on page 41 for
i
nformation on the total amount of addressable memory.
• Minimum total system memory: 256 MB
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR3 1333, DDR3 1066, and DDR3 800 MHz SDRAM DIMMs
NOTES
• Remove the video card in the Primary PCI Express x16 before installing or
upgrading memory to avoid interference with the memory retention mechanism.
• To be fully compliant with all applicable DDR SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect
(SPD) data structure. This allows the BIOS to read the SPD data and program the
chipset to accurately configure memory settings for optimum performance. If nonSPD memory is installed, the BIOS will attempt to correctly configure the memory
settings, but performance and reliability may be impacted or the DIMMs may not
function under the determined frequency.

Product Description
1.5.1 Memory Configurations
The Intel 82X38 MCH 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 8 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.
NOTE
The DIMM 0 sockets of both channels are blue. The DIMM 1 sockets of both channels
are black.

X38 Chipset
The Intel X38 chipset consists of the following devices:
• Intel 82X38 Memory Controller Hub (MCH) with Direct Media Interface (DMI)
interconnect
• Intel 82801IR I/O Controller Hub (ICH9R)
The MCH component provides interfaces to the processor, memory, and PCI Express.
The ICH9R is a centralized controller for the board’s I/O paths.
For information about Refer to

1.6.1 USB
The board supports up to twelve USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers.
The ICH9R provides the USB controller for all ports. The port arrangement is as
follows:
• Eight ports are implemented with dual stacked back panel connectors adjacent to
the audio connectors
• Four ports are routed to two separate front panel USB headers

Intel Desktop Board DX38BT Technical Product Specification
1.6.2 Serial ATA Interfaces
The board provides six Serial ATA (SATA) connectors, which support one device per
connector. The board also provides two red-colored external Serial ATA (eSATA)
connectors on the back panel.
1.6.2.1 Serial ATA Support
The board’s Serial ATA controller offers six independent Serial ATA ports with a
theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed
on each port for a maximum of six Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA IDE which supports a
master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
and 15). In Native mode, standard PCI Conventional bus resource steering is used.
Native mode is the preferred mode for configurations using the Windows* XP and
Windows Vista operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.

The board provides a discrete Marvell* controller to support two eSATA connectors on
the back panel and one PATA connector.
1.7.1 External Serial ATA Support
The red Serial ATA connectors on the back panel can be used for an external SATA
drive. They can also be used for port replication, which allows the aggregation of
multiple hard drives on each of the eSATA ports. Figure 10 on page 44 shows the
l
ocation of the External Serial ATA-compatible SATA ports on the back panel.
The Marvell 88SE621 controller uses the PCI Express for data transfer with a
theoretical maximum transfer rate of 3 Gbits/sec per port. These connectors are in
addition to the six SATA connectors of the ICH9R SATA interface.
The discrete SATA interface supports the following RAID levels:
• RAID 0
• RAID 1
NOTE
The Marvell 88SE621 controller supports single drive non-RAID configurations as well
as RAID configurations. For RAID configurations, you must install the RAID drivers by
pressing F6 during operating system installation. See your operating system
installation documentation for more information about installing drivers during the
installation process.

1.7.2 Parallel ATA 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/sec.
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
• ATA-66: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
21
Intel Desktop Board DX38BT Technical Product Specification
NOTE
ATA-66 and ATA-100 are faster timings and require an 80-pin conductor 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.

1.8 Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 12 shows the location of the battery.

Product Description
1.9 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• Intelligent power management, including a programmable wake-up event interface
• PCI power management support
The BIOS Setup program provides configuration options for the I/O controller.
1.9.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer
Infrared usage models. Microsoft Windows Vista is the supported operating system
The CIR feature is made up of two separate pieces: the receiving (receiver) header,
and the output (emitter) header. The receiving header consists of a filtered translated
infrared input compliant with Microsoft CIR specifications, and also a “learning”
infrared input. This learning input is simply a high pass input which the computer can
use to “learn” to speak the infrared communication language of other user remotes.
The emitter header consists of two output ports which the PC can use to emulate
“learned” infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to plug into Intel
Desktop Boards for this feature to work. These interface modules may be included in
some boxed versions of DX38BT boards.

(Note 1)
(Note 2)
The use of these wake-up events from an ACPI state requires an operating system
that provides full ACPI support. In addition, software, drivers, and peripherals must
fully support ACPI wake events.
1.13.2 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
34
Product Description
• LAN wake capabilities
• Instantly Available PC technology
• Wake from USB
• PME# signal wake-up support
• WAKE# signal wake-up support
• Wake from Consumer IR
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 11, page 45
The signal names of the main power connector Table 18, page 51
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 or S1 state.
• The fans are off when the board is off or in the S3, S4, or S5 state.
• Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan control ASIC
• All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed
• All fan headers have a +12 V DC connection
• 4-Pin fan headers are controlled by Pulse Width Modulation
• 3-Pin fan headers (front and rear) are modulated by voltage control

Intel Desktop Board DX38BT Technical Product Specification
1.13.2.3 LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable
of providing adequate +5 V standby current. Failure to provide adequate standby
current when implementing LAN wake capabilities can damage the power supply.
LAN wake capabilities enable remote wake-up of the computer through a network.
The LAN 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
⎯ By Ping
⎯ Magic Packet
• The onboard LAN subsystem
• Wake from CIR
1.13.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power supply
must be capable of providing adequate +5 V standby current. Failure to provide
adequate standby current when implementing Instantly Available PC technology can
damage the power supply.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the
power supply is off, and the front panel LED is amber if dual colored, or off if single
colored.) When signaled by a wake-up device or event, the system quickly returns to
its last known wake state. Table 7 on page 34 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 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.

1.13.2.5 Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
Product Description
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.13.2.6 PME# Signal Wake-up Support
When the PME# signal on the PCI Conventional bus is asserted, the computer wakes
from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in the 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 +5 V Standby Power Indicator LED and Additional LEDs
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 on the board.

2.1 Memory Resources
2.1.1 Addressable Memory
The board utilizes 8 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 device), and chipset overhead resides above the top of DRAM
(total system memory). On a system that has 8 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 device (16 Mbit)
• Local APIC (19 MB)
• Digital Media Interface (40 MB)
• Front side bus interrupts (17 MB)
• PCI Express configuration space (256 MB)
• MCH base address registers PCI Express ports (up to 256 MB)
• Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCI
Express add-in cards (256 MB)
The board provides the capability to reclaim the physical memory overlapped by the
memory mapped I/O logical address space. The board remaps physical memory from
the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical
address range located just above the 4 GB boundary. Figure 9 shows a schematic of
the system memory map. All installed system memory can be used when there is no
overlap of system addresses.

The other internal connectors and 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 or 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 or 1394 header single wire connectors may
eventually overload the overcurrent protection and cause damage to the board.
This section describes the board’s connectors. The connectors can be divided into
these groups:
• Back panel I/O connectors
• Component-side I/O connectors and headers (see page 45)
2.2.1 Back Panel Connectors
The back panel configuration is dependent upon which audio subsystem is present.
The configurations are as follows:
• 8-channel (7.1) audio subsystem (five analog audio output connectors and two
digital audio output connectors), described on page 44

2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• PCI Express 2.0 x16: two PCI Express 2.0 x16 connectors supporting
simultaneous transfer speeds up to 8 GB/sec of peak bandwidth per direction and
up to 16 GB/sec concurrent bandwidth.
• PCI Express 1.1 x4: one PCI Express 1.1 x4 connector (implemented using a x16
physical connector). The x4 interface supports simultaneous transfer speeds up to
250 MB/sec of peak bandwidth per direction and up to 2 GB/sec concurrent
bandwidth.
• PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card
connectors. The SMBus is routed to all PCI Conventional bus connectors. PCI
Conventional bus add-in cards with SMBus support can access sensor data and
other information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
• 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.

2.2.2.4 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 4 connector. This connector provides power
directly to the processor voltage regulator and must always be used. Failure to do
so will prevent the board from booting.
• Auxiliary PCI Express graphics power – a 1 x 4 connector. This connector
provides the required additional power when using high power (75 W or greater)
add-in cards in either or both the Secondary PCI Express x16 (electrical x8) and
the PCI Express x16 (electrical x4) bus add-in card connectors. See Figure 1 for
locat
ion.
CAUTION
If high power (75 W or greater) add-in cards are installed in either or both the
Secondary PCI Express x16 (electrical x8) and the PCI Express x16 (electrical x4) bus
add-in card connectors, the Auxiliary PCI Express graphics power connector must be
used. Failure to do so may cause damage to the board and the add-in cards.
Furthermore, if you use a 2 X 10 power cable, you must also use the Auxiliary PCI
Express graphics power connector to ensure stable board operation.

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 130 W processor (see section 1.4
on page 15 for a list of supported processors), 1 GB DDR3 RAM, one high end video
card, one hard disk drive, one optical drive, and all board peripherals enabled, the
minimum recommended power supply is 460 W. Table 24 lists the recommended
power supply current values.

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 25 lists the current capability of the fan headers.
Table 25. Fan Header Current Capability

Front chassis fan 1.5 A
MCH Fan 3.5 A (direct connect 12V rail)
Rear chassis fan 1.5 A
Auxiliary rear chassis fan 2.0 A
2.5.3 Add-in Board Considerations
The board is designed to provide 2 A (average) of current for each add-in board from
the +5 V rail. The total +5 V current draw for add-in boards for a fully loaded board
(all six expansion slots filled) must not exceed the system’s power supply +5 V
maximum current or 14 A in total.
2.6 Thermal Considerations
CAUTION
A chassis with a maximum internal ambient temperature of 38 oC at the processor fan
inlet is a requirement. Use a processor heat sink that provides omni-directional
airflow to maintain required airflow across the processor voltage regulator area.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel desktop boards please refer to the
following website:
http://developer.intel.com/design/motherbd/cooling.htm
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
58
Technical Reference
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 Section2.8.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do so may result in damage to the voltage regulator circuit. The processor
voltage regulator area (shown in Figure 17) can reach a temperature of up to 85
an open chassis.

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, LAN
EEPROM information, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The initial production BIOSs are identified as
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.

3.2 BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 16 Mbit
(2048 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.
64
Overview of BIOS Features
3.3.2 PCI IDE Support
If you select IDE in the BIOS Setup program, the BIOS automatically sets up the
PCI IDE connector with independent I/O channel support. The IDE interface supports
hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including
CD-ROM drives, tape drives, and Ultra DMA drives. The BIOS determines the
capabilities of each drive and configures them to optimize capacity and performance.
To take advantage of the high capacities typically available today, hard drives are
automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4,
depending on the capability of the drive. You can override the auto-configuration
options by specifying manual configuration in the BIOS Setup program.
To use ATA-66/100 features the following items are required:
• An ATA-66/100 peripheral device
• An ATA-66/100 compatible cable
• ATA-66/100 operating system device drivers
NOTE
Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master
device. For example, do not connect an ATA hard drive as a slave to an ATAPI
CD-ROM drive.
3.4 System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing
computers in a managed network.
The main component of SMBIOS is the Management Information Format (MIF)
database, which contains information about the computing system and its
components. Using SMBIOS, a system administrator can obtain the system types,
capabilities, operational status, and installation dates for system components. The
MIF database defines the data and provides the method for accessing this information.
The BIOS enables applications such as third-party management software to use
SMBIOS. The BIOS stores and reports the following SMBIOS information:
• BIOS data, such as the BIOS revision level
• Fixed-system data, such as peripherals, serial numbers, and asset tags
• Resource data, such as memory size, cache size, and processor speed
• Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems 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.
65
Intel Desktop Board DX38BT 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.
66
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
• Intel
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
®
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.
®
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.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.
For information about Refer to
BIOS update utilities http://support.intel.com/support/motherboards/desktop/sb

3.6.1 Language Support
The BIOS Setup program and help messages are supported in US English. Additional
languages are available in the Integrator’s Toolkit utility. Check the Intel website for
details.
3.6.2 Custom Splash Screen
During POST, an Intel® splash screen is displayed by default. This splash screen can
be augmented with a custom splash screen. The Intel Integrator’s Toolkit that is
available from Intel can be used to create a custom splash screen.
NOTE

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 30 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 30.
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
legacy diskette drive interface
Acceptable Drives/Media Types for BIOS Recovery
No

Overview of BIOS Features
3.8 Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard
drive, USB drive, USB flash drive, CD-ROM, or the network. The default setting is for
the diskette drive to be the first boot device, the hard drive second, and the ATAPI
CD-ROM third. If enabled, the last default boot device is the network.
3.8.1 CD-ROM Boot
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM
format specification. Under the Boot menu in the BIOS Setup program, ATAPI CDROM is listed as a boot device. Boot devices are defined in priority order. Accordingly,
if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot
from the next defined drive.
3.8.2 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 31 lists the boot device menu options.
Table 31.

Intel Desktop Board DX38BT Technical Product Specification
3.9 Adjusting Boot Speed
These factors affect system boot speed:
• Selecting and configuring peripherals properly
• Optimized BIOS boot parameters
3.9.1 Peripheral Selection and Configuration
The following techniques help improve system boot speed:
• Choose a hard drive with parameters such as “power-up to data ready” less than
eight seconds, that minimize hard drive startup delays.
• Select a CD-ROM drive with a fast initialization rate. This rate can influence POST
execution time.
• Eliminate unnecessary add-in adapter features, such as logo displays, screen
repaints, or mode changes in POST. These features may add time to the boot
process.
• Try different monitors. Some monitors initialize and communicate with the BIOS
more quickly, which enables the system to boot more quickly.
3.9.2 BIOS Boot Optimizations
Use of the following BIOS Setup program settings reduces the POST execution time.
• In the Boot Menu, set the hard disk drive as the first boot device. As a result, the
POST does not first seek a diskette drive, which saves about one second from the
POST execution time.
• In the Peripheral Configuration submenu, disable the LAN device if it will not be
used. This can reduce up to four seconds of option ROM boot time.
NOTE
It is possible to optimize the boot process to the point where the system boots so
quickly that the Intel logo screen (or a custom logo splash screen) will not be seen.
Monitors and hard disk drives with minimum initialization times can also contribute to
a boot time that might be so fast that necessary logo screens and POST messages
cannot be seen.
This boot time may be so fast that some drives might be not be initialized at all. If
this condition should occur, it is possible to introduce a programmable delay ranging
from zero to 30 seconds by 5 second increments (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.
Table 32 shows the effects of setting the supervisor password and user password.

Intel Desktop Board DX38BT Technical Product Specification
4.4 Port 80h POST Codes
During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O
port 80h. If the POST fails, execution stops and the last POST code generated is left
at port 80h. This code is useful for determining the point where an error occurred.
Displaying the POST codes requires a PCI bus add-in card, often called a POST card.
The POST card can decode the port and display the contents on a medium such as a
seven-segment display.
NOTE
The POST card must be installed in PCI bus connector 1.
The following tables provide information about the POST codes generated by the
BIOS:
• Table 35 lists the Port 80h POST code ranges
• Table 36 lists the Port 80h POST codes themselves
• Table 37 lists the Port 80h POST sequence
NOTE
In the tables listed above, all POST codes and range values are listed in hexadecimal.

5.1.3.3 Lead Free Desktop Board
This 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 Desktop Board is lead free although certain discrete components used on the
board contain a small amount of lead which is necessary for component performance
and/or reliability. This 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 39 shows the various forms of the “Lead-Free 2
