Intel Workstation Board S975XBX2 Technical Product Specification
1.4 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.8 V and 1.9 V DDR2 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 47 for
information on the total amount of addressable memory.
• Minimum total system memory: 128 MB
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR2 800, DDR2 667, and DDR2 533 MHz SDRAM DIMMs
NOTES
• Remove the Primary PCI Express x16 (electrical x16 or x8) video card 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.
Table 4 lists the supported DIMM configurations.

1.4.1 Memory Configurations
The Intel 82975X MCH 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
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.
Figure 3 illustrates the memory channel and DIMM configuration.
NOTE
The DIMM0 sockets of both channels are blue. The DIMM1 sockets of both channels
are black.

• Intel 82975X Memory Controller Hub (MCH) with Direct Media Interface (DMI)
interconnect
• Intel 82801GR I/O Controller Hub (ICH7-R) with DMI interconnect
The MCH is a centralized controller for the system bus, the memory bus, the PCI
Express bus, and the DMI interconnect. The ICH7 is a centralized controller for the
board’s I/O paths. The BIOS code is stored in the Serial Peripheral Interface (SPI)
Flash device.
For information about Refer to
The Intel 975X chipset http://developer.intel.com/
Resources used by the chipset Chapter 2
1.5.1 USB

UHCI- and EHCI-compatible drivers.
The ICH7-R provides the USB controller for all ports. The port arrangement is as
follows:
• Four 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
NOTES
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.

Product Description
1.5.2 IDE Support
The board provides five IDE interface connectors:
• One parallel ATA IDE connector that supports two devices
• Four serial ATA IDE connectors that support one device per connector
1.5.2.1 Parallel ATE IDE Interface
The ICH7-R’s 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 ICH7-R/
ICH7-DH’s 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 using the transfer modes.
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.
For information about Refer to
The location of the Parallel ATA IDE connector Figure 16, page 56
1.5.2.2 Serial ATA Interfaces
The ICH7-R’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.
25
Intel Workstation Board S975XBX2 Technical Product Specification
Native mode is the preferred mode for configurations using the Microsoft Windows* XP
and Microsoft 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/
For information about Refer to
The location of the Serial ATA IDE connectors on the S975XBX2 board Figure 16, page 56
1.5.2.3 Serial ATA RAID
The ICH7-R supports the following RAID (Redundant Array of Independent Drives)
levels:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and mirroring
• RAID 5 - distributed parity
1.5.2.4 SCSI Hard Drive Activity LED Header
The SCSI hard drive activity LED header is a 1 x 2-pin header that allows an add-in
hard drive controller to use the same LED as the onboard IDE controller. For proper
operation, this header should be wired to the LED output of the add-in hard drive
controller. The LED indicates when data is being read from, or written to, either the
add-in hard drive controller or the onboard IDE controller (Parallel ATA or Serial ATA).
For information about Refer to
The location of the SCSI hard drive activity LED header Figure 16, page 56
The signal names of the SCSI hard drive activity LED header Table 22, page 59
1.5.3 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 14 shows the location of the battery.

Intel Workstation Board S975XBX2 Technical Product Specification
1.7 PCI Express Connectors
The board provides the following PCI Express connectors:
• One Primary PCI Express x16 (electrical x16 or x8) bus add-in card connector. The
x16 interface supports simultaneous (full duplex) transfers up to 8 GBytes/sec.
Single-ended (half duplex) transfers are supported at up to 4 GBytes/sec.
• One Secondary PCI Express x16 (electrical x8) bus add-in card connector: The
board provides a PCI Express add-in card connector in the form of a physical x16
connector with electrical routing of x8. This connector is an electrical equivalent of
a PCI Express x8 bus add-in card connector. This connector also supports x4 and
x1 PCI Express add-in cards.
• One PCI Express x16 (electrical x4) bus add-in card connector: The board
provides a PCI Express add-in card connector in the form of a physical x16
connector with electrical routing of x4. This connector is an electrical equivalent of
a PCI Express x4 bus add-in card connector. This connector supports x4 and x1
PCI Express add-in cards.
For optimum performance, observe the following recommendations for the PCI Express
add-in card connectors:
• If you are installing a single PCI Express Graphics card, install it in the Primary
PCI Express x16 (electrical x16 or x8) bus add-in card connector.
• If you are installing two PCI Express Graphics cards, install them in the Primary
PCI Express x16 (electrical x16 or x8) bus add-in card connector and the
Secondary PCI Express x16 (electrical x8) bus add-in card connector.
The PCI Express interfaces for the Primary and Secondary PCI Express x16 connectors
are routed through the MCH. The PCI Express interface for the PCI Express x16
(electrical x4) connector is routed through the ICH7-R/ICH7-DH. Therefore, the
Primary and Secondary PCI Express x16 connectors provide higher performance than
the PCI Express x16 (electrical x4) bus add-in card connector.
For information about Refer to
The locations of the specific PCI Express x16 add-in card connectors Figure 1, page 14

1.12.3 Fan Monitoring
Fan monitoring can be implemented using Intel Workstation Utilities or third-party
software. The level of monitoring and control is dependent on the hardware
monitoring ASIC used with the Workstation Board.
For information about Refer to
The functions of the fan headers Section 1.13.2.2, page 42
1.12.4 Chassis Intrusion and Detection
The board supports a chassis security feature that detects if the chassis cover is
removed. The security feature uses a mechanical switch on the chassis that attaches
to the chassis intrusion header. When the chassis cover is removed, the mechanical
switch is in the closed position.
1.13 Power Management
Power management is implemented at several levels, including:
• Software support through Advanced Configuration and Power Interface (ACPI)
• Hardware support:
⎯ Power connector
⎯ Fan headers
⎯ LAN wake capabilities
⎯ Instantly Available PC technology
⎯ Resume on Ring
⎯ Wake from USB
⎯ Wake from PS/2 devices
⎯ Power Management Event signal (PME#) wake-up support
⎯ PCI Express WAKE# signal support
1.13.1 ACPI
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with this board requires an
operating system that provides full ACPI support. ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices, add-in boards (some add-in
boards may require an ACPI-aware driver), video displays, and hard disk drives
• Methods for achieving less than 15-watt system operation in the power-on/standby
sleeping state
• A Soft-off feature that enables the operating system to power-off the computer
• Support for multiple wake-up events (see Table 9 on page 41)
• Support for a front panel power and sleep mode switch

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.

WAKE# S1, S3, S4, S5
Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option
to Power On will enable a wake-up event from LAN in the S5 state.
(Note)
(Note)
NOTE
The use of these wake-up events from an ACPI state requires an operating system
that provides full ACPI support. In addition, software, drivers, and peripherals must
fully support ACPI wake events.
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
• Resume on Ring
• 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.
41
Intel Workstation Board S975XBX2 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.
1.13.2.1 Power Connector
When an ACPI-enabled system receives the appropriate 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 16, page 56
The signal names of the main power connector Table 24, page 60
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
For information about Refer to

Product Description
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 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 Conventional bus PME# signal for PCI 2.2 compliant LAN designs
• The onboard LAN subsystem
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 9 on page 41 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 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.
1.13.2.5 Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from ACPI S1 or S3 states
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation
43
Intel Workstation Board S975XBX2 Technical Product Specification
1.13.2.6 Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.13.2.7 Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
1.13.2.8 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).
1.13.2.9 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.
1.13.2.10 +5 V Standby Power Indicator LED
The +5 V standby power indicator LED shows that power is still present even when the
computer appears to be off. Figure 13 shows the location of the standby power
indicator LED on the S975XBX2 board.
CAUTION
If AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.

Product Description
1.14 Trusted Platform Module
The optional Trusted Platform Module (TPM) is a component on the Workstation board
that is specifically designed to enhance platform security above-and-beyond the
capabilities of today’s software by providing a protected space for key operations and
other security critical tasks. Using both hardware and software, the TPM protects
encryption and signature keys at their most vulnerable stages—operations when the
keys are being used unencrypted in plain-text form. The TPM is specifically designed
to shield unencrypted keys and platform authentication information from softwarebased attacks.

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 (8 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, 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
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 14 shows a schematic of

2.6 PCI Conventional Interrupt Routing Map
This section describes interrupt sharing and how the interrupt signals are connected
between the PCI Conventional bus connectors and onboard PCI Conventional devices.
The PCI Conventional specification describes how interrupts can be shared between
devices attached to the PCI Conventional 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 Conventional device should not share an interrupt with other PCI Conventional
devices. Use the following information to avoid sharing an interrupt with a PCI
Conventional add-in card.
PCI Conventional 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-R/ICH7-DH has eight Programmable Interrupt Request (PIRQ) input signals.
All PCI Conventional interrupt sources either onboard or from a PCI Conventional
add-in card connect to one of these PIRQ signals. Some PCI Conventional interrupt
sources are electrically tied together on the board and therefore share the same
interrupt. Table 15 shows an example of how the PIRQ signals are routed.

PCI bus connector 2 INTD INTC INTA INTB
IEEE-1394a controller INTA
Discrete SATA Controller INTA
PIRQA PIRQB PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH
NOTE
ICH7-R/ICH7-DH PIRQ Signal Name
In PIC mode, the ICH7-R/ICH7-DH 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 interruptconstrained situations, it is possible for two or more of the PIRQ lines to be connected
to the same IRQ signal. Refer to Table 14 for the allocation of PIRQ lines to IRQ
signals in APIC mode.
PCI interrupt assignments to the USB ports, Serial ATA ports, and PCI Express ports
are dynamic.

2.7 Connectors
CAUTION
Only the following connectors have overcurrent protection: back panel USB, front
panel USB, and PS/2.
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.
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 56)

2.7.2.1 Power Supply Connectors
The board has three power supply connectors:
• Main power – a 2 x 12 connector. The board requires a power supply with a
2 x 12 main power cable.
• Processor core power – This connector provides power directly to the processor
voltage regulator and must always be used. Depending on manufacturing options,
the board will contain either a 2 x 4 or a 2 x 2 connector for the processor voltage
regulator.
• 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.
CAUTION
Regardless of the connector type (2 x 4 or a 2 x 2), the Processor core power
connector must always be used. Failure to do so will prevent the board from booting.
If the board is equipped with a 2 x 4 power connector, you must use a power supply
with a dual-rail 2 x 4 Processor core power cable. Failure to do so may cause damage
to the board.
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.

2.10 Electrical Considerations
2.10.1 DC Loading
Table 33 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 clock
frequency.
Table 33. DC Loading Characteristics
DC Current at:
Mode DC Power +3.3 V +5 V +12 V -12 V +5 VSB

Maximum loading 750 W 25 A 27 A 46 A 0.40 A 0.34 A (S0)
2.10.2 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 the Workstation board is as follows:
a fully loaded board (all five expansion slots) must not exceed 10 A.

Technical Reference
2.10.3 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 34 lists the current capability of the fan headers.
Table 34. Fan Header Current Capability
Fan Connector Maximum Available Current
Processor fan 3.0 A
Front chassis fan 1.5 A
Rear chassis fan 1.5 A
Auxiliary rear fan 3.0 A
MCH fan (optional) 1.5 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 33 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 following recommendations found in 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

2.11 Thermal Considerations
This board features a thermal protection circuit in the processor voltage regulator area.
This circuit protects the processor voltage regulator from overheating and damaging
the board. The thermal protection circuit in the processor voltage regulator sensor is
triggered at approximately 120
throttling mode (slowing down the processor if it exceeds its maximum operating
temperature) and allow the processor voltage regulator to cool down.
INTEGRATOR’S NOTE
#
Use a processor heatsink that provides omni-directional airflow to maintain required
airflow across the processor voltage regulator area.
CAUTION
When using BIOS Setup program options to increase processor voltage and frequency
above the supported ranges, the temperature in the processor voltage regulator area
will rise. This area of the board will require increased airflow. Direct airflow over the
processor voltage regulator is crucial to preventing throttling and keeping the
processor voltage regulator area cool. This is particularly important when using liquid
cooling.

3.1 Introduction
The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device and can be
updated using a disk-based program. The SPI 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 BX97520J.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.
Maintenance Main Advanced Performance Security Power Boot Exit
NOTE
The maintenance menu is displayed only when the board is in configure mode.
Section 2.8 on page 67 shows how to put the board in configure mode.
The performance menu is an optional menu and not present on all versions of the
board.

3.2 Resource Configuration
3.2.1 PCI Autoconfiguration
The BIOS automatically configures 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.
3.2.2 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 interface also supports
second-generation SATA 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
78
Overview of BIOS Features
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 CDROM drive.
3.3 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 clock frequency
• Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems, such as Microsoft 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.
3.4 Watchdog Timer
The board includes a watchdog timer circuit. The watchdog timer provides automatic
recovery after two failed power-on self-tests (POSTs) following use of the BIOS
performance menu.
79
Intel Workstation Board S975XBX2 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.
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.
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, 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
• Intel
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.

Overview of BIOS Features
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 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.
For information about
The Intel World Wide Web site Section 1.2, page 17
Refer to
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.
81
Intel Workstation Board S975XBX2 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 39 lists the boot device menu options.

Overview of BIOS Features
3.8 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 40 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 Workstation Board S975XBX2 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 43 lists the Port 80h POST code ranges
• Table 44 lists the Port 80h POST codes themselves
• Table 45 lists the Port 80h POST sequence
NOTE
In the tables listed above, all POST codes and range values are listed in hexadecimal.
