interface is 16 GB/s in each direction, simultaneously, for a bandwidth of 32 GB/s.
• PCI Express 2.x with a raw bit rate of 5.0 GT/s results in an effective bandwidth of
4.0 Gb/s each direction per lane. The maximum theoretical bandwidth of the x16
interface is 8 GB/s in each direction, simultaneously, for a bandwidth of 16 GB/s.
• PCI Express 1.x with a raw bit rate of 2.5 GT/s results in an effective bandwidth of
2.0 Gb/s each direction per lane. The maximum theoretical bandwidth of the x16
interface is 4 GB/s in each direction, simultaneously, for a bandwidth of 8 GB/s.

Product Description
1.5.1 Memory Configurations
The Intel Core i7 and Intel Xeon processors support the following types of memory
organization:
• Quad channel (Interleaved) mode. This mode offers the highest throughput for
real world applications.
• Tri channel (Interleaved) mode. Tri channel mode is enabled when the installed
memory capacities of any three DIMM channels are equal.
• Dual channel (Interleaved) mode. 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.

Product Description
1.7 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 via the power supply 5V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be
notified during POST.
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 13 shows the location of the battery.
1.8 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• Intelligent power management, including a programmable wake-up event interface
• PCI power management support
The BIOS Setup program provides configuration options for the I/O controller.
1.8.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer
Infrared usage models. Microsoft Windows Vista and Microsoft Windows 7 are the
supported operating systems.
The CIR feature is made up of two separate pieces: the receiving (receiver) header,
and the output (emitter) header. The receiving header consists of a filtered translated
infrared input compliant with Microsoft CIR specifications, and also a “learning”
infrared input. This learning input is simply a high pass input which the computer can
use to “learn” to speak the infrared communication language of other user remotes.
The emitter header consists of two output ports which the PC can use to emulate
“learned” infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to plug into Intel
Desktop Boards for this feature to work.

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.

CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable
of providing adequate +5 V standby current. Failure to provide adequate standby
current when implementing LAN wake capabilities can damage the power supply.
LAN wake capabilities enable remote wake-up of the computer through a network.
The LAN subsystem PCI bus network adapter monitors network traffic at the Media
Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem
asserts a wake-up signal that powers up the computer. Depending on the LAN
implementation, the board supports LAN wake capabilities with ACPI in the following
ways:
• The PCI Express WAKE# signal
• The PCI bus PME# signal for PCI 2.3 compliant LAN designs
⎯ By Ping
⎯ Magic Packet
• The onboard LAN subsystem

Product Description
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 8 on page 34 lists the devices and events that can
wake the co
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.
mputer from the S3 state.
The use of Instantly Available PC technology requires operating system support and
PCI 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.
1.13.2.5 Wake from USB
USB bus activity wakes the computer from an ACPI S3 state.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and is supported by the operating system.
1.13.2.6 PME# Signal Wake-up Support
When the PME# signal on the Conventional PCI bus is asserted, the computer wakes
from an ACPI S3, S4, or S5 state (with Wake on PME enabled in the BIOS).
1.13.2.7 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S3, S4, or S5 state.
1.13.2.8 Wake from Consumer IR
CIR activity wakes the computer from an ACPI S3, S4, or S5 state.
1.13.2.9 Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake
from an ACPI S5 state.

2.1 Memory Resources
2.1.1 Addressable Memory
The board utilizes 64 GB of addressable system memory. Typically the address space
that is allocated for Conventional PCI 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 64 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 (64 Mbit)
• Local APIC (19 MB)
• Direct Media Interface (40 MB)
• PCI Express configuration space (256 MB)
• PCH base address registers PCI Express ports (up to 256 MB)
• Memory-mapped I/O that is dynamically allocated for Conventional PCI and PCI
Express add-in cards (256 MB)
The board provides the capability to reclaim the physical memory overlapped by the
memory mapped I/O logical address space. The board remaps physical memory from
the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical
address range located just above the 4 GB boundary. Figure 10 shows a schematic of
t
he system memory map. All installed system memory can be used when there is no
overlap of system addresses.

2.2 Connectors and Headers
CAUTION
Only the following connectors and headers have overcurrent protection: back panel
and front panel USB, as well as IEEE 1394a.
The other internal connectors and headers are not overcurrent protected and should
connect only to devices inside the computer’s chassis, such as fans and internal
peripherals. Do not use these connectors or headers to power devices external to the
computer’s chassis. A fault in the load presented by the external devices could cause
damage to the computer, the power cable, and the external devices themselves.
Furthermore, improper connection of USB or 1394 header single wire connectors may
eventually overload the overcurrent protection and cause damage to the board.
This section describes the board’s connectors. The connectors can be divided into
these groups:
• Back panel I/O connectors
• Component-side I/O connectors and headers (see page 48)

2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• PCI Express 3.0 x16: three PCI Express 3.0 x16 connectors supporting
simultaneous transfer speeds up to 16 GB/s of peak bandwidth per direction and
up to 32 GB/s concurrent bandwidth.
• PCI Express 2.0 x1: two PCI Express 2.0 x1 connectors. The x1 interface supports
simultaneous transfer speeds up to 500 MB/s of peak bandwidth per direction and
up to 1.0 GB/s concurrent bandwidth.
• Conventional PCI (rev 2.3 compliant) bus: one Conventional PCI bus add-in card
connector.
Note the following considerations for the Conventional PCI bus connector:
• The Conventional PCI bus connectors are bus master capable.
• SMBus signals are routed to the Conventional PCI bus connectors. This enables
Conventional PCI bus add-in boards with SMBus support to access sensor data on
the desktop board. The specific SMBus signals are as follows:
⎯ The SMBus clock line is connected to pin A40.
⎯ The SMBus data line is connected to pin A41.

2.5.1 Power Supply Considerations
CAUTION
The +5 V standby line from the power supply must be capable of providing adequate
+5 V standby current. Failure to do so can damage the power supply. The total
amount of standby current required depends on the wake devices supported and
manufacturing options.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the indicated parameters of the ATX form factor
specification.
• The potential relation between 3.3 VDC and +5 VDC power rails
• The current capability of the +5 VSB line
• All timing parameters
• All voltage tolerances
For example, for a system consisting of a supported 130 W processor (see section 1.4
on page 16 for a list of supported processors),
card, one hard disk drive, one optical drive, and all board peripherals enabled, the
minimum recommended power supply is 460 W. Table 27 lists the recommended

maximum current or 14 A in total.
62
Technical Reference
2.6 Thermal Considerations
CAUTION
A chassis with a maximum internal ambient temperature of 38 oC at the processor fan
inlet is a requirement. Use a processor heat sink that provides omni-directional airflow
to maintain required airflow across the processor voltage regulator area. If a non
omni-directional thermal solution is used customer might need to provide
supplemental cooling to the processor voltage regulator area.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel desktop boards please refer to the
following website:
http://www3.intel.com/cd/channel/reseller/asmo-na/eng/tech_reference/53211.htm
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the board’s maximum operating
temperature. Failure to do so could cause components to exceed their maximum case
temperature and malfunction. For information about the maximum operating
temperature, see the environmental specifications in Section 2.8.
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 18) can reach a temperature of up to 85
an open chassis.

3 Overview of BIOS Features
3.1 Introduction
The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash
contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN
EEPROM information, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The initial production BIOSs are identified as SIX7910J.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 Configuration Performance Security Power Boot Exit
NOTE
The maintenance menu is displayed only when the board is in configure mode.

3.2 BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 32 Mbit (4096 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.
68
Overview of BIOS Features
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.
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.

Intel Desktop Board DX79SR Technical Product Specification
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
• Intel
• Intel
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
®
Express BIOS Update utility, which enables automated updating while in the
Windows environment. Using this utility, the BIOS can be updated from a file on a
hard disk, a USB drive (a flash drive or a USB hard drive), an optical drive, or from
the file location on the Web.
®
Flash Memory Update Utility, which requires booting from DOS. Using this
utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash
drive or a USB hard drive), or an optical drive.
®
F7 switch allows a user to select where the BIOS .bio file is located and
perform the update from that location/device. Similar to performing a BIOS
Recovery without removing the BIOS configuration jumper.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.

Overview of BIOS Features
3.6.2 Custom Splash Screen
During POST, an Intel® splash screen is displayed by default. This splash screen can
be augmented with a custom splash screen. The Intel Integrator’s Toolkit that is
available from Intel can be used to create a custom splash screen.
NOTE
If you add a custom splash screen, it will share space with the Intel branded logo.

Intel Desktop Board DX79SR Technical Product Specification
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, optical drive, or the network. The default setting is
for the diskette drive to be the first boot device, the hard drive second, and the optical
drive third. If enabled, the last default boot device is the network.
3.8.1 Optical Drive Boot
Booting from the optical drive is supported in compliance to the El Torito bootable
CD-ROM format specification. Under the Boot menu in the BIOS Setup program, the
optical drive is listed as a boot device. Boot devices are defined in priority order.
Accordingly, if there is not a bootable CD in the optical 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 34 lists the boot de

Overview of BIOS Features
3.9 Adjusting Boot Speed
These factors affect system boot speed:
• Selecting and configuring peripherals properly
• Optimized BIOS boot parameters
3.9.1 Peripheral Selection and Configuration
The following techniques help improve system boot speed:
• Choose a hard drive with parameters such as “power-up to data ready” in less than
eight seconds to minimize hard drive startup delays.
• Select an optical 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.
• The BIOS will automatically not load the option ROM for the SATA controller if no
drives are installed in it during POST.
NOTE
It is possible to optimize the boot process to the point where the system boots so
quickly that the Intel logo screen (or a custom logo splash screen) will not be seen.
Monitors and hard disk drives with minimum initialization times can also contribute to
a boot time that might be so fast that necessary logo screens and POST messages
cannot be seen.
This boot time may be so fast that some drives might be not be initialized at all. If
this condition should occur, it is possible to introduce a programmable delay ranging
from zero to 30 seconds by 5 second increments (using the Hard Disk Pre-Delay
feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup
program).
73
Intel Desktop Board DX79SR Technical Product Specification
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 35 shows the effects of setting the s
upervisor password and user password.

Error Messages and Beep Codes
4.5 Port 80h POST Codes
During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O
port 80h. If the POST fails, execution stops and the last POST code generated is left
at port 80h. This code is useful for determining the point where an error occurred.
Displaying the POST codes requires a PCI bus add-in card, often called a POST card.
The POST card can decode the port and display the contents on a medium such as a
seven-segment display.
NOTE
The POST card must be installed in PCI bus connector 1.
The following tables provide information about the POST codes generated by the BIOS:
• Table 39 lists the Port 80h POST code ranges
• Table 40 lists the Port 80h POST codes themselves
• Table 41 lists the Port 80h POST sequence
NOTE
In the tables listed above, all POST codes and range values are listed in hexadecimal.
