Hi-Speed USB 2.0 Support
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a
shielded cable that meets the requirements for a full-speed USB device.
These Intel desktop boards support up to six USB 2.0 ports via ICH4; four ports routed to the back
panel and two routed to a USB front panel header. 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 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.
NOTE
✏
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.
Enhanced IDE Interface

Accelerated Graphics Port (AGP)
NOTE
✏
Desktop Boards D845GRG and D845GBV are only compatible with 1.5 V AGP cards.
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.
AGP is independent of the PCI bus and is intended for exclusive use with graphical
display devices.
The AGP connector supports 1.5 V AGP 4X and 2X add-in cards.
Communication and Networking Riser (CNR) (Optional)
The optional CNR provides an interface that supports various features such as audio, modem,
USB, and LAN.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be updated by following the instructions in Chapter 3 on page 37.
PCI Auto Configuration
If you install a PCI add-in card in your computer, the PCI 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 add-in card.
16
Desktop Board Features
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE 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 an IDE device. You can override the autoconfiguration 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
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
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 available for viewing
and changing depending on whether the supervisor or user password was entered.
• Setting a user password restricts who can boot the computer. The password prompt is
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, you can enter either password
to boot the computer.
Power Management Features
Power management is implemented at several levels, including:
• Advanced Configuration and Power Interface (ACPI)
• Suspend to RAM (Instantly Available PC technology)
ACPI
ACPI gives the operating system direct control over the power management and Plug & Play
functions of a computer. The use of ACPI with Desktop Board D845GRG or D845GBV requires
an operating system that provides full ACPI support.
17
Intel Desktop Boards D845GRG and D845GBV Product Guide
Suspend to RAM (Instantly Available PC Technology)
CAUTION
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.
Instantly Available technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep
state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up
device or event, the system quickly returns to its last known awake state.
The Intel desktop board’s standby power indicator, shown in Figure 3, is lit when there is standby
power to the system. This includes the memory modules and PCI bus connectors, even when the
computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber.
CR6H1
OM13591
Figure 3. Location of Standby Power Indicator

Intel desktop board connectors can be divided into three groups:
• Back panel connectors
• Midboard connectors
— Audio connectors
— Power and hardware connectors
— Add-in board and peripheral interface connectors
• Front panel headers
CAUTION
Many of the midboard and front panel connectors provide operating voltage (+5 V dc and
+12 V dc, for example) to devices inside the computer chassis, such as fans and internal
peripherals. These connectors are not overcurrent protected. Do not use these connectors for
powering devices external to the computer chassis. A fault in the load presented by the external
devices could cause damage to the computer, the interconnecting cable, and the external devices
themselves.

• Damage to wires that could cause a short circuit
Observe all warnings and cautions that instruct you to refer computer servicing to qualified
technical personnel.
Installation Instructions
CAUTION
Follow these guidelines to meet safety and regulatory requirements when installing this board
assembly.
Read and adhere to all of these instructions and the instructions supplied with the chassis and
associated modules. If the instructions for the chassis are inconsistent with these instructions or
the instructions for associated modules, contact the supplier’s technical support to find out how
you can ensure that your computer meets safety and regulatory requirements. If you do not follow
these instructions and the instructions provided by chassis and module suppliers, you increase
safety risk and the possibility of noncompliance with regional laws and regulations.
Ensure Electromagnetic Compatibility (EMC) Compliance
Before computer integration, make sure that the power supply and other modules or peripherals, as
applicable, have passed Class B EMC testing and are marked accordingly.
In the installation instructions for the host chassis, power supply, and other modules pay close
attention to the following:
• Product certifications or lack of certifications
• External I/O cable shielding and filtering
• Mounting, grounding, and bonding requirements
• Keying connectors when mating the wrong connectors could be hazardous
If the power supply and other modules or peripherals, as applicable, are not Class B EMC
compliant before integration, then EMC testing is required on a representative sample of the newly
completed computer.

Intel Desktop Boards D845GRG and D845GBV Product Guide
Chassis and Component Certifications
Ensure that the chassis and certain components; such as the power supply, peripheral drives,
wiring, and cables; are components certified for the country or market where used. Agency
certification marks on the product are proof of certification. Typical product certifications include:
In Europe
The CE marking signifies compliance with all applicable European requirements. If the chassis
and other components are not properly CE marked, a supplier’s Declaration of Conformity
statement to the European EMC directive and Low Voltage directive (as applicable), should be
obtained. Additionally, other directives, such as the Radio and Telecommunications Terminal
Equipment (R&TTE) directive may also apply depending on product features.
In the United States
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or
ETL signifies compliance with safety requirements. Wiring and cables must also be UL listed or
recognized and suitable for the intended use. The FCC Class B logo for home or office use
signifies compliance with electromagnetic interference (EMI) requirements.
In Canada
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety
requirements. The Industry Canada statement at the front of this product guide demonstrates
compliance with Canadian EMC regulations. Industry Canada recognizes and accepts FCC
certification as denoting compliance with national electromagnetic interference (emissions)
requirements.
Prevent Power Supply Overload
Do not overload the power supply output. To avoid overloading the power supply, make sure that
the calculated total current loads of all the modules within the computer is less than the output
current rating of each of the power supplies output circuits.
Place Battery Marking
There is insufficient space on this desktop board to provide instructions for replacing and
disposing of the Lithium ion coin cell battery. For system safety certification, the following
statement or equivalent statement is required to be permanently and legibly marked on the chassis
