Desktop Board Features
USB 2.0 Support
The Desktop Board supports up to 12 USB 2.0 ports (eight ports routed to back panel
connectors and four ports routed to two onboard headers) via the ICH9R. USB 2.0
ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function
normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports
to USB 1.1 operation. This may be required to accommodate operating systems that
do not support USB 2.0.
Enhanced IDE Interface
The board’s IDE interface handles the exchange of information between the processor
and peripheral devices such as hard disk drives and CD-ROM drives. The interface
supports:
• Up to two IDE devices (such as hard drives)
• ATAPI-style devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols
Serial ATA
Desktop Board DX48BT2 supports six onboard Serial ATA channels (3.0 Gb/s) via
ICH9R and two eSATA channels (3.0 Gb/s) via a discrete controller.
The six onboard Serial ATA channels provided by ICH9R support 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 data mirroring
• RAID 5 - distributed parity
For information on configuring your system for RAID using Intel
Technology see Chapter 4.

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and IDE auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions on page 63 in Chapter 3.
Serial ATA and IDE Auto Configuration
If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the
auto-configuration utility in the BIOS automatically detects and configures the device
for your computer. You do not need to run the BIOS Setup program after installing a
Serial ATA or IDE device. You can override the auto-configuration options by
specifying manual configuration in the BIOS Setup program.
PCI and PCI Express* Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration utility in the BIOS automatically detects and configures the
resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need
to run the BIOS Setup program after you install a PCI/PCI Express add-in card.
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then

Power Management
Power management is implemented at several levels, including software support
through the Advanced Configuration and Power Interface (ACPI) and the following
hardware support:
• Power connectors
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology (Suspend to RAM)
• +5 V standby power indicator LED
• Wake from USB
• Power Management Event signal (PME#) wakeup support
• WAKE# signal wake-up support
• ENERGY STAR capable
Software Support
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 the Desktop Board requires an
operating system that provides full ACPI support.
Hardware Support
Power Connectors
ATX12V-compliant power supplies can turn off the computer power through system
control. When an ACPI-enabled computer 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 (either on or off). The computer’s response can
be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.
The Desktop Board has three power connectors. See Figure 30 on page 55 for the
location of the power co
nnectors.
20
Page 21
Desktop Board Features
Fan Headers
The function/operation of the fans is as follows:
• The fans are on when the computer is in the ACPI S0 state.
• The fans are off when the computer is in the ACPI S3, S4, or S5 state.
• Each fan header is wired to a tachometer input of the hardware monitoring and
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.
The Desktop Board has a 4-pin processor fan header, one 4-pin and two 3-pin chassis
fan headers, and one 3-pin MCH fan header.
LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current. Failure to provide adequate standby
current when using this feature can damage the power supply.
LAN wakeup capabilities enable remote wake-up of the computer through a network.
The LAN subsystem monitors network traffic and upon detecting a Magic Packet*
frame, it asserts a wake-up signal that powers up the computer.
Instantly Available PC Technology
CAUTIONS
For Instantly Available PC technology, the 5 V standby line for the power supply must
be capable of delivering adequate +5 V standby current. Failure to provide adequate
standby current when using this feature can damage the power supply and/or effect
ACPI S3 sleep state functionality.
Power supplies used with this Desktop Board must be able to provide enough standby
current to support the standard Instantly Available (ACPI S3 sleep state) configuration.
If the standby current necessary to support multiple wake events from the PCI and/or
USB buses exceeds power supply capacity, the Desktop Board may lose register
settings stored in memory.
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. If
the computer has a dual-colored power LED on the front panel, the sleep state is
indicated by the LED turning amber. When signaled by a wake-up device or event, the
computer quickly returns to its last known awake state.
21
Page 22
Intel Desktop Board DX48BT2 Product Guide
The Desktop Board supports the PCI Bus Power Management Interface Specification.
Add-in cards that support this specification can participate in power management and
can be used to wake the computer.
+5 V Standby Power Indicator
CAUTION
If the 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.
The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is
standby power still present on the board even when the computer appears to be off.
For example, when this LED is lit, standby power is still present at the memory module
sockets and the PCI bus connectors.

Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S3 state.
PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S1, S3, S4, or S5 state.
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.
ENERGY STAR* Capable
In 2007, the US Department of Energy and the US Environmental Protection Agency
revised the ENERGY STAR requirements. Intel worked directly with these two
governmental agencies to define the new requirements. Currently Intel Desktop
Boards are capable of meeting the new ENERGY STAR requirements depending upon
system configuration.

computer. You can access the BIOS Setup program by pressing the <F2> key after
the Power-On Self-Test (POST) memory test begins and before the operating system
boot begins.
This chapter tells you how to update the BIOS by either using the Intel Express BIOS
Update utility or the Iflash Memory Update utility, and how to recover the BIOS if an
update fails.
Updating the BIOS with the Intel® Express
BIOS Update Utility
With the Intel Express BIOS Update utility you can update the system BIOS while in
the Windows environment. The BIOS file is included in an automated update utility
that combines the functionality of the Intel
of use of Windows-based installation wizards.
®
Flash Memory Update Utility and the ease
To update the BIOS with the Intel Express BIOS Update utility:
1. Go to the Intel World Wide Web site:
http://support.intel.com/support/motherboards/desktop/
2. Navigate to the DX48BT2 page, click “[view] Latest BIOS updates,” and select the
Express BIOS Update utility file.
3. Download the file to your hard drive. (You can also save this file to a removable
USB device. This is useful if you are updating the BIOS for multiple identical
systems.)
4. Close all other applications. This step is required. Your system will be rebooted at
the last Express BIOS Update window.
5. Double-click the executable file from the location on your hard drive where it was
saved. This runs the update program.
6. Follow the instructions provided in the dialog boxes to complete the BIOS update.

Updating the BIOS with the ISO Image BIOS
Update File or the Iflash Memory Update
Utility
You can use the information in this section to update the BIOS using either the Iflash
Memory Update Utility or the ISO Image BIOS update file.
Obtaining the BIOS Update File
You can update to a new version of the BIOS by using the ISO Image BIOS update file
(recommended), or Iflash BIOS update file.
The ISO Image BIOS update file is a standardized image of a bootable CD-ROM that
can be used to create a bootable CD that will update the BIOS.
The Iflash BIOS update file is a compressed file that contains the files you need to
update the BIOS. The Iflash BIOS update file contains:
• New BIOS file (including the Intel
• Intel
• Intel Flash Memory Update Utility
®
Integrator Toolkit Configuration File (optional)
®
Management Engine Firmware Image)
You can obtain either of these files through your computer supplier or by navigating to
the Desktop Board DX48BT2 page on the Intel World Wide Web site at:
http://support.intel.com/support/motherboards/desktop
Navigate to the DX48BT2 page, click “[view] Latest BIOS updates,” and select the ISO
Image BIOS Update or Iflash BIOS Update utility file.
Updating the BIOS with the ISO Image BIOS Update
File
The ISO Image BIOS update allows for the update of an Intel® Desktop Board BIOS to
the latest production release regardless of the operating system installed on the
computer's hard drive and without the need to remove the BIOS configuration jumper.
It requires a blank CD-R, a read/writeable CD drive, and software capable of
uncompressing and writing the ISO image file to CD.
The image uses ISOLINUX* bootloader and automatically launches a script to upgrade
the BIOS via the Iflash utility.
64
Page 65
Updating the BIOS
CAUTION
Do not interrupt the process or the system may not function properly.
Follow these instructions to upgrade the BIOS using the ISO Image BIOS file:
1. Download the ISO Image BIOS file.
2. Using software capable of uncompressing and writing an ISO image file to CD, burn
the data to a blank CD.
NOTE
Copying the ISO Image BIOS file to CD will not work. The completed CD should
contain multiple files and a directory.
3. Insert the CD that was created in the CD-ROM drive of the computer to be
upgraded and boot the system.
4. When the "Press ENTER to continue booting from CD-ROM" prompt appears, press
the Enter key. The system will boot from the hard drive if no key is pressed within
15 seconds.
5. At the "Welcome to the Intel Desktop Board BIOS Upgrade CD-ROM" page, press
any key to confirm the BIOS upgrade operation.
6. Wait for the BIOS upgrade process to complete.
CAUTION
DO NOT POWER DOWN YOUR COMPUTER before the update is complete. The update
may take up to 5 minutes.
Updating the BIOS with the Iflash Memory Update
Utility
With the Iflash Memory update utility you can update the system BIOS from a
bootable CD-ROM, bootable USB flash drive, or other bootable USB media. The utility
available on the Intel World Wide Web site provides a simple method for creating a
bootable CD-ROM that will automatically update your BIOS. The Iflash BIOS update
files can also be extracted locally to your hard drive and copied to a bootable USB
flash drive or other bootable USB media.
The Iflash Memory update utility allows you to:
• Update the BIOS and Intel Management Engine in flash memory
• Update the language section of the BIOS
NOTE
Review the instructions distributed with the update utility before attempting a BIOS
update.
65
Page 66
Intel Desktop Board DX48BT2 Product Guide
CAUTION
Do not interrupt the process or the system may not function properly.
1. Uncompress the BIOS update file and copy the .BIO file, IFLASH.EXE, and .ITK file
(optional) to a bootable USB flash drive or other bootable USB media.
2. Configure the BIOS or use the F10 option during POST to boot to the USB device.
3. Manually run the IFLASH.EXE file from the USB device and manually update the
BIOS.
Recovering the BIOS
It is unlikely that anything will interrupt the BIOS update; however, if an interruption
occurs, the BIOS could be damaged. Due to BIOS size and recovery requirements, a
CD-R with the .BIO file in the root directory will be required.

Intel Desktop Board DX48BT2 Product Guide
Lead-free 2LI/Pb-free 2LI Board
The electronics industry is transitioning to European Union (EU) Restriction of
Hazardous Substances (RoHS)-compliant products. The RoHS legislation restricts the
use of six materials. One of these restricted materials is lead. Lead is the most
common and problematic of the RoHS restricted materials.
There are exemptions in RoHS that allow the use of lead in some very limited locations
in electronic products. Maximum lead concentration values have been established for
RoHS-compliant electronic products that allow up to 1000 ppm of lead.
Lead-free/Pb-free is a nickname that is often used (or misused) for RoHS-compliant
products. In this case, the term "Lead-free/Pb-free" means that lead has been
removed where required by the RoHS legislation but still may exist as an impurity
below 1000 ppm.
The term "Lead-free 2LI/Pb-free 2LI" means lead-free second level interconnect (2LI).
The balls, leads, or pads used to connect the component to a printed circuit board are
lead-free, but the first level interconnect (FLI) is not lead-free. The use of lead in the
FLI is acceptable because of the RoHS "flip chip" or "die bump" interconnect
exemption.
Desktop Board DX48BT2 is a lead-free second level interconnect product. Table 18
shows
accompanying collateral. These marks are based on JEDEC standard J-STD-609,
“Marking and Labeling of Components, PCBs and PCBAs to Identify Lead, Lead Free
and Other Attributes.”

Restriction of Hazardous Substances (RoHS)
EU RoHS
EU RoHS Directive 2002/95/EC restricts the use of the following six materials in
various types of electronic and electrical equipment:
• Lead
• Mercury
• Cadmium
• Hexavalent chromium
• Polybrominated biphenyls (PBB)
• Polybrominated diphenyl ether (PBDE)
The maximum concentrations allowed are 0.1% or 1000 ppm (except for cadmium,
which is limited to 0.01% or 100 ppm) by weight of homogeneous material.
Desktop Board DX48BT2 complies with these restrictions.

China RoHS
“China RoHS” is the term used by industry generally to describe legislation
implemented by the Ministry of Information Industry (MII) in the People's Republic of
China for the control of pollution by electronic information products (EIP). The official
title of the China RoHS regulation is “Management Methods for Controlling Pollution by
Electronic Information Products.”
China RoHS bans the same substances and has the same limits as EU RoHS.
However, the China RoHS regulation requires specific product marking and a selfdeclaration of the controlled substances contained in each product.
Desktop Board DX48BT2 is a China RoHS-compliant product.
The required China RoHS mark indicates the product’s Environmental Friendly Usage
Period (EFUP). The EFUP is defined as the number of years for which listed controlled
substances will not leak or chemically deteriorate while in the product. The EFUP for
Intel Desktop Boards has been determined to be 10 years.
The EFUP for Desktop Board DX48BT2 is shown in Table 19.
