Non-ECC DIMMs  
Serial Presence Detect  
DDR2 667 or DDR2 800 MHz SDRAM DIMMs  
DDR2 667 DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)  
DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)  
NOTE  
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 enables the BIOS to read the SPD data and program the chipset to  
accurately configure memory settings for optimum performance. If non-SPD 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 82G33 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 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.

are black.  
Figure 3. Memory Channel Configuration and DIMM Configuration  
INTEGRATOR’S NOTE  
#
Regardless of the memory configuration used (dual channel, single channel, or flex  
mode), DIMM 0 of Channel A must always be populated. This is a requirement of the  
Intel Management Engine in ICH9DH.

the board’s I/O paths.  
The chipset supports the following features:  
Onboard Graphics  
Dynamic Video Memory Technology  
USB  
Serial ATA  
Parallel IDE  
For information about  
The Intel G33 Express chipset  
Resources used by the chipset  
Refer to  
Chapter 2  
1.6.1  
Intel G33 Graphics Subsystem  
The Intel G33 Express chipset contains two separate, mutually exclusive graphics  
options. Either the Intel Graphics Media Accelerator 3100 (Intel GMA 3100) graphics  
controller (contained within the 82G33 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  
3100 graphics controller is disabled.  
1.6.1.1  
Intel® Graphics Media Accelerator 3100 Graphics  
Controller  
The Intel GMA 3100 graphics controller features the following:  
400 MHz core frequency  
High quality texture engine  
DX9.0c* and OpenGL* 1.4 compliant  
Hardware Pixel Shader 2.0

Video  
Software DVD at 30 fps full screen  
DVMT support up to 256 MB  
Display  
Supports analog displays up to 2048 x 1536 at 75 Hz refresh (QXGA)  
Dual independent display support  
DDC2B compliant interface with Advanced Digital Display 2 card or Media  
Expansion Card (ADD2/MEC), support for TV-out/TV-in and DVI digital display  
connections  
1.6.1.2 Dynamic Video Memory Technology (DVMT)  
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. Up to 256 MB of system memory can be  
allocated to DVMT on systems that have 512 MB or more of total system 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  
Advanced Digital Display (ADD2/MEC) Card Support  
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a  
225 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC card is  
detected, the Intel GMA 3100 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 card. An ADD2/MEC card can either be configured to

1.6.4  
Serial ATA Interfaces  
The board provides four Serial ATA (SATA) connectors, which support one device per  
connector.  
1.6.4.1  
Serial ATA Support  
The DG33BU Desktop Board’s Serial ATA controller offers four independent Serial ATA  
ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device  
can be installed on each port for a maximum of four Serial ATA devices. A point-to-  
point interface is used for host to device connections, unlike Parallel ATA IDE which  
supports a master/slave configuration and two devices per channel.  
For compatibility, the underlying Serial ATA functionality is transparent to the  
operating system. The Serial ATA controller can operate in both legacy and native  
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14  
and 15). In Native mode, standard PCI Conventional bus resource steering is used.  
Native mode is the preferred mode for configurations using the Windows* XP  
operating system.

Intel Desktop Board DG33BU Technical Product Specification  
NOTE  
Many Serial ATA drives use new low-voltage power connectors and require adapters or  
power supplies equipped with low-voltage power connectors.

Refer to  
The location of the Serial ATA connectors  
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/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.  
ATA-133: DMA protocol on IDE bus allows host and target throttling. The ATA-133  
logic is designed to achieve read transfer rates up to 133 MB/sec and write transfer  
rates in excess of 100 MB/sec.  
NOTE  
ATA-66, ATA-100, and ATA-133 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.

1.8 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

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.

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  
Wake from PS/2 keyboard  
PME# signal wake-up support  
WAKE# signal wake-up support  
LAN wake capabilities and Instantly Available PC technology require power from the  
+5 V standby line.  
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 and the Front and  
Rear fan headers share the tachometer input of the hardware monitoring and fan  
control device. All fan headers support closed-loop fan control that can adjust the  
fan speed or switch the fan on or off as needed.  
All fan headers have a +12 V DC connection.  
For information about  
Refer to  
The locations of the fan headers and thermal sensors  
The signal names of the processor fan header

1.13.2.3 LAN Wake Capabilities  
CAUTION  
For LAN wake capabilities, the +5 V standby line from the power supply must be  
capable of providing adequate +5 V standby current. Failure to provide adequate  
standby current when implementing LAN wake capabilities can damage the power  
supply.  
LAN wake capabilities enable remote wake-up of the computer through a network.  
The LAN subsystem PCI bus network adapter monitors network traffic at the Media  
Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem  
asserts a wake-up signal that powers up the computer. Depending on the LAN  
implementation, the board supports LAN wake capabilities with ACPI in the following  
ways:  
The PCI Express WAKE# signal  
The PCI bus PME# signal for PCI 2.3 compliant LAN designs  
The onboard LAN subsystem  
34  
   
Product Description  
1.13.2.4 Instantly Available PC Technology  
CAUTION  
For Instantly Available PC technology, the +5 V standby line from the power supply  
must be capable of providing adequate +5 V standby current. Failure to provide  
adequate standby current when implementing Instantly Available PC technology can  
damage the power supply.  
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-  
RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the  
power supply is off, and the front panel LED is amber if dual colored, or off if single  
colored.) When signaled by a wake-up device or event, the system quickly returns to  
its last known wake state. Table 8 on page 32 lists the devices and events that can  
wake the computer from the S3 state.  
The board supports the PCI Bus Power Management Interface Specification. Add-in  
boards that also support this specification can participate in power management and  
can be used to wake the computer.  
The use of Instantly Available PC technology requires operating system support and  
PCI 2.3 compliant add-in cards and drivers.  
1.13.2.5 Wake from USB  
USB bus activity wakes the computer from ACPI S3 state.  
NOTE  
Wake from USB requires the use of a USB peripheral that supports Wake from USB.  
1.13.2.6 Wake from PS/2 Devices  
PS/2 device activity wakes the computer from an ACPI S3 state.  
1.13.2.7 PME# Signal Wake-up Support  
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI  
S3, S4, or S5 state (with Wake on PME enabled in BIOS).  
1.13.2.8 WAKE# Signal Wake-up Support  
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from  
an ACPI S3, S4, or S5 state.  
35

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), 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 (8 Mbits)  
Local APIC (19 MB)  
Digital Media Interface (40 MB)  
Front side bus interrupts (17 MB)  
PCI Express configuration space (256 MB)

2.2 Connectors and Headers  
CAUTION  
Only the following connectors and headers have overcurrent protection: Back panel  
and front panel USB, PS/2, and VGA.  
The other internal connectors/headers are not overcurrent protected and should  
connect only to devices inside the computer’s chassis, such as fans and internal  
peripherals. Do not use these connectors/headers to power devices external to the  
computer’s chassis. A fault in the load presented by the external devices could cause  
damage to the computer, the power cable, and the external devices themselves.  
NOTE  
Computer systems that have an unshielded cable attached to a USB port may not  
meet FCC Class B requirements, even if no device is attached to the cable. Use  
shielded cable that meets the requirements for full-speed devices.  
This section describes the board’s connectors and headers. The connectors and  
headers can be divided into these groups:  
Back panel I/O connectors (see page 41)  
Component-side connectors and headers (see page 42)

Add-in Card Connectors  
The board has the following add-in card connectors:  
One PCI Express x16 connector supporting simultaneous transfer speeds up to  
4 GBytes/sec of peak bandwidth per direction and up to 8 GBytes/sec concurrent  
bandwidth.  
PCI Express x1: one PCI Express x1 connector. The x1 interface supports  
simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per  
direction and up to 500 MBytes/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.

Power Supply Connectors  
The board has the following power supply connectors:  
Main power – a 2 x 12 connector. This connector is compatible with 2 x 10  
connectors previously used on Intel Desktop boards. The board supports the use  
of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When  
using a power supply with a 2 x 10 main power cable, attach that cable on the  
rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24  
unconnected.  
Processor core power – a 2 x 2 connector. 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.

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  
one optical drive, and all board peripherals enabled, the minimum recommended  
power supply is 300 W. Table 25 lists the recommended power supply current values.

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 (all three  
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:  
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.  
53  
       
Intel Desktop Board DG33BU 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 oC in  
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, 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 DPP3510A.86A.  
When the BIOS Setup configuration jumper is set to configure mode and the computer  
is powered-up, the BIOS compares the CPU version and the microcode version in the  
BIOS and reports if the two match.  
The BIOS Setup program can be used to view and change the BIOS settings for the  
computer. The BIOS Setup program is accessed by pressing the <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 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.  
58  
         
Overview of BIOS Features  
3.3.2  
PCI IDE Support  
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the  
PCI IDE connector with independent I/O channel support. The IDE interface supports  
hard drives up to ATA-66/100/133 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-66/100/133 features the following items are required:  
An ATA-66/100/133 peripheral device  
An ATA-66/100/133 compatible cable  
ATA-66/100/133 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.  
59  
   
Intel Desktop Board DG33BU 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.

Overview of BIOS Features  
3.6 BIOS Updates  
The BIOS can be updated using either of the following utilities, which are available on  
the Intel World Wide Web site:  
Intel® Express BIOS Update utility, which enables automated updating while in the  
Windows environment. Using this utility, the BIOS can be updated from a file on a  
hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from  
the file location on the Web.  
Intel® Flash Memory Update Utility, which requires booting from DOS. Using this  
utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash  
drive or a USB hard drive), or a CD-ROM.  
Both utilities verify that the updated BIOS matches the target system to prevent  
accidentally installing an incompatible BIOS.  
NOTE  
Review the instructions distributed with the upgrade utility before attempting a BIOS  
update.  
For information about  
Refer to  
BIOS update utilities  
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.  
61  
   
Intel Desktop Board DG33BU Technical Product Specification  
3.6.2  
Custom Splash Screen  
During POST, an Intel® splash screen is displayed by default. This splash screen can  
be augmented with a custom splash screen. The Intel® Integrator Toolkit that is  
available from Intel can be used to create a custom splash screen.  
NOTE  
If you add a custom splash screen, it will share space with the Intel branded logo.  
Refer to

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 31 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 31.Acceptable Drives/Media Types for BIOS Recovery  
Media Type  
Can be used for BIOS recovery?

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 32 lists the boot device menu options.  
Table 32.Boot Device Menu Options

Intel Desktop Board DG33BU 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 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).  
64  
     
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 33 shows the effects of setting the supervisor password and user password.  
This table is for reference only and is not displayed on the screen.

Intel Desktop Board DG33BU 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.  
NOTE  
In the tables listed above, all POST codes and range values are listed in hexadecimal.

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.
