System Memory
The board has two DIMM sockets and support the following memory features:
•
•
1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
•
•
•
•
•
4 GB maximum total system memory. Refer to Section 2.1.1 on page 37 for
information on the total amount of addressable memory.
Minimum total system memory: 512 MB
Non-ECC DIMMs
Serial Presence Detect
DDR2 667 or DDR2 533 MHz SDRAM DIMMs
NOTE
A minimum of 512 MB of system memory is required to fully enable both the onboard
graphics and the manageability engine.
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 allows 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.
Table 3 lists the supported DIMM configurations.

Product Description
NOTE
Regardless of the DIMM type used, the memory frequency will either be equal to or
less than the processor system bus frequency. For example, if DDR2 667 memory is
used with a 533 MHz system bus frequency processor, the memory will operate at
533 MHz. Table 4 lists the resulting operating memory frequencies based on the
combination of DIMMs and processors.

Memory Configurations
The Intel 82946GZ GMCH supports two 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

1.5.1.2
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.

Section 1.2, page 15
1.5.1.4
Advanced Digital Display (ADD2/ADD2+) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
200 MHz pixel clock to the PCI Express x16 connector. The SDVO ports can be paired
for a dual channel configuration to support up to a 400 MHz pixel clock. When an
ADD2/ADD2+ card is detected, the Intel GMA 3000 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/ADD2+ card. An ADD2/ADD2+ card can
either be configured to support simultaneous display with the primary VGA display or
can be configured to support dual independent display as an extended desktop
configuration with different color depths and resolutions. ADD2/ADD2+ cards can be
designed to support the following configurations:
•
•
•
•
•

Product Description
1.5.3
Serial ATA Interfaces
The board provides four Serial ATA (SATA) connectors, which support one device per
connector.
1.5.3.1
Serial ATA Support
The ICH7’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 and
Windows 2000 operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adaptors or
power supplies equipped with low-voltage power connectors.
For more information, see: http://www.serialata.org/.

Intel Desktop Board D946GZTS Technical Product Specification
1.5.4
Parallel IDE Interface
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.
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.

1.5.5
Real-Time Clock, CMOS SRAM, and Battery
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.

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 7 lists the power states supported by the board along with the associated
system power targets. See the ACPI specification for a complete description of the
various system and power states.

1.10.1.2 Two-Watt Standby
In 2001, the U.S. government issued an executive order requiring a reduction in
power for appliances and personal computers. This board meets that requirement by
operating at 1.5 W (or less) in S5 (Standby) mode. Two-Watt operation applies only
to the S5 state when the computer is turned off, but still connected to AC power.
Two-Watt operation does not apply to the S3 (Suspend to RAM) or S4 (Suspend to
disk) states.
Newer energy-efficient power supplies using less than 0.5 W (in Standby mode) may
also be needed to achieve this goal.

that provides full ACPI support. In addition, software, drivers, and peripherals must
fully support ACPI wake events.
1.10.2
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.

Fan headers
LAN wake capabilities
Instantly Available PC technology
Resume on Ring
Wake from USB

33
Intel Desktop Board D946GZTS Technical Product Specification
Resume on Ring enables telephony devices to access the computer when it is in a
power-managed state. The method used depends on the type of telephony device
(external or internal).
NOTE
The use of Resume on Ring and Wake from USB technologies from an ACPI state
requires an operating system that provides full ACPI support.
1.10.2.1
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.

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 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.

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
The onboard LAN subsystem
1.10.2.4
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 8 on page 33 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

Memory Map
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 (4 Mbits)
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, 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)
37
Intel Desktop Board D946GZTS Technical Product Specification
The amount of installed memory that can be used will vary based on add-in cards and
BIOS settings. Figure 12 shows a schematic of the system memory map. All installed
system memory can be used when there is no overlap of system addresses.

PCI Interrupt Routing Map
This section describes interrupt sharing and how the interrupt signals are connected
between the PCI bus connectors and onboard PCI devices. The PCI specification
specifies how interrupts can be shared between devices attached to the PCI bus. In
most cases, the small amount of latency added by interrupt sharing does not affect
the operation or throughput of the devices. In some special cases where maximum
performance is needed from a device, a PCI device should not share an interrupt with
other PCI devices. Use the following information to avoid sharing an interrupt with a
PCI add-in card.
PCI devices are categorized as follows to specify their interrupt grouping:
•
•
•
INTA: By default, all add-in cards that require only one interrupt are in this
category. For almost all cards that require more than one interrupt, the first
interrupt on the card is also classified as INTA.
INTB: Generally, the second interrupt on add-in cards that require two or more
interrupts is classified as INTB. (This is not an absolute requirement.)
INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC
and a fourth interrupt is classified as INTD.
The ICH7 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI
interrupt sources either onboard or from a PCI add-in card connect to one of these
PIRQ signals. Some PCI interrupt sources are electrically tied together on the board
and therefore share the same interrupt. Table 14 shows an example of how the
PIRQ signals are routed.

NOTE
In PIC mode, the ICH7 can connect each PIRQ line internally to one of the IRQ signals
(3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a
PIRQ line will have a unique interrupt. However, in certain interrupt-constrained
situations, it is possible for two or more of the PIRQ lines to be connected to the same
IRQ signal. Refer to Table 13 for the allocation of PIRQ lines to IRQ signals in APIC
mode.
PCI interrupt assignments to USB ports and Serial ATA ports are dynamic.

Connectors and Headers
CAUTION
Only the following connectors 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.
This section describes the board’s connectors and headers. The connectors and
headers can be divided into these groups:

Add-in Card Connectors
The board has the following add-in card connectors:
•
•
•
PCI Express x16: one 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 PCI Conventional bus connector 2 only. 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 PCI Conventional bus connector 2. 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.

Intel Desktop Board D946GZTS Technical Product Specification
2.7.2.2
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.

CAUTION
Do not move the jumper with the power on. Always turn off the power and unplug the
power cord from the computer before changing a jumper setting. Otherwise, the
board could be damaged.
Figure 17 shows the location of the jumper block. The jumper determines the BIOS
Setup program’s mode. Table 27 lists the jumper settings for the three modes:
normal, configure, and recovery. When the jumper is set to configure mode and the
computer is powered-up, the BIOS compares the processor version and the microcode

2.10 Electrical Considerations
2.10.1
DC Loading
Table 28 lists the DC loading characteristics of the board. This data is based on a DC
analysis of all active components within the board that impact its power delivery
subsystems. The analysis does not include PCI add-in cards. Minimum values assume
a light load placed on the board that is similar to an environment with no applications
running and no USB current draw. Maximum values assume a load placed on the
board that is similar to a heavy gaming environment with a 500 mA current draw per
USB port. These calculations are not based on specific processor values or memory
configurations but are based on the minimum and maximum current draw possible
from the board’s power delivery subsystems to the processor, memory, and USB
ports.
Use the datasheets for add-in cards, such as PCI, to determine the overall system
power requirements. The selection of a power supply at the system level is dependent
on the system’s usage model and not necessarily tied to a particular processor speed.

2.10.3
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 (all three
expansion slots and the PCI Express x16 connector filled) must not exceed 8 A.
2.10.4
Power Supply Considerations
CAUTION
The +5 V standby line for 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.
System integrators should refer to the power usage values listed in Table 28 when
selecting a power supply for use with the board.
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
58
Technical Reference
2.11 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
This board requires the use of a BTX Type I or Type II Thermal Module for the
processor.
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.
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 2.13.
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 20) can reach a temperature of up to 85 oC in
an open chassis.

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 TS94610J.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.

BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 4 Mbit (512 KB)
flash memory device
3.3
3.3.1
Resource Configuration
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 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 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, such as Windows NT*, 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.
65
Intel Desktop Board D946GZTS 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.
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.
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 1.44 MB diskette, or a CD-ROM, or from the file location on the Web.
Intel® Flash Memory Update Utility, which requires creation of a boot diskette and
manual rebooting of the system. Using this utility, the BIOS can be updated from
a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette
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.

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 Integrator’s 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.

Section 1.2, page 15
3.7
Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard
drives, 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.
3.7.1
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.
3.7.2
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.
67
Intel Desktop Board D946GZTS Technical Product Specification
3.7.3
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
3.7.4
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 34 lists the boot device menu options.

3.8
Adjusting Boot Speed
These factors affect system boot speed:
•
•
3.8.1
Selecting and configuring peripherals properly
Optimized BIOS boot parameters
Peripheral Selection and Configuration
The following techniques help improve system boot speed:
•
•
•
•
68
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.
Overview of BIOS Features
3.8.2
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).
69
Intel Desktop Board D946GZTS Technical Product Specification
3.9
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 35 shows the effects of setting the supervisor password and user password.

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.
