NOTE
✏
The line out connector, located on the back panel, is designed to power either headphones or
amplified speakers only. Poor audio quality may occur if passive (non-amplified) speakers are
connected to this output.
Audio drivers and utilities are available from Intel’s World Wide Web site:
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 43.
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.
15
Intel Desktop Boards D845HV and D845WN Product Guide
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 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
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.
LAN Subsystem (Optional)
The optional Intel 82562ET (with the Intel 82801BA ICH2) provides a Fast PCI LAN subsystem
providing both 10Base-T and 100Base-TX connectivity. The Intel 82562ET provides the
following functions:
•
•
•
•

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 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.

Desktop Board Features
CAUTION
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.
Power supplies used with this board must be able to provide enough standby current to support the
standard Instantly Available (ACPI S3 sleep state) configuration as outlined in Table 4. Values are
determined by specifications such as PCI 2.2. Actual measurements may vary.
To estimate the total amount of standby current required for a particular system configuration,
standby current requirements of all installed components must be added. Refer to the descriptions
in and follow the steps outlined below:
1. Note the total D845HV or D845WN board standby current requirement.
2. Add to that the total PS/2 port standby current requirement if a wake-enabled device is
connected.
3. Add, from the PCI 2.2 slots (wake-enabled) row, the total of the number of wake-enabled
devices installed (PCI and AGP) multiplied by the standby current requirement.
4. Add, from the PCI 2.2 slots (nonwake-enabled) row, the total of the number of wake-enabled
devices installed (PCI and AGP) multiplied by the standby current requirement.
5. Add all additional wake-enabled devices’ and nonwake-enabled devices’ standby current
requirements as applicable.
6. Add all the required current totals from steps 1 through 5 to determine the total estimated
standby current power supply requirement.

Connecting the IDE Cable
The Intel® boxed desktop board package includes two IDE cables. Both are capable of connecting
two drives to the desktop board. The 40-contact cable supports the Ultra DMA-33 transfer
protocol. The 40-contact, 80-conductor cable supports ATA-66 and ATA-100 transfer protocols
and is backward compatible with drives using slower IDE transfer protocols. Figure 16 shows the
correct installation of the cable.
NOTE
✏
ATA-66/100 compatible cables are backward compatible with drives using slower IDE transfer
protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are
attached to the same cable, the maximum transfer rate between the drives may be reduced to that
of the slowest drive.
NOTE

Intel Desktop Boards D845HV and D845WN Product Guide
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.
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.
86
Regulatory Compliance
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
