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 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.
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:
• Basic 10/100 Ethernet LAN connectivity

PCI card wake up support
17
Intel Desktop Boards D845HV and D845WN Product Guide
Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from the ACPI S1 state
• Requires only one call to access the computer
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation
Instantly Available Technology
CAUTION
For Instantly Available 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 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.

Figure 3. Location of Standby Power Indicator
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
✏
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 CD-ROM drive.
For correct function of the cable:
• Attach the cable end with the single connector to the board.
• Attach the cable end with the two closely spaced connectors to the drives.

Updating 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. The following steps explain how to recover the BIOS if an update fails.
The following procedure uses recovery mode for the Setup program. See page 37 for more
information on Setup modes.
NOTE
✏
Because of the small amount of code available in the boot block area, there is no video support.
You will not see anything on the screen during this procedure. Monitor the procedure by listening
to the speaker and looking at the diskette drive LED.
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external
peripherals.
2. Remove the computer cover and locate the configuration jumper block (J9G1) (see Figure 17).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.

3
4. Insert the bootable BIOS update diskette into diskette drive A.
5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to
boot. The recovery process will take a few minutes.
6. Listen to the speaker:
• Upon applying power, drive A will begin to show activity. In about a minute, two beeps
are heard and drive A activity ceases (temporarily) indicating the successful recovery of
the BIOS core. Drive A activity will begin again followed by two more beeps indicating
the successful recovery of the boot block. This sequence of events indicates a successful
BIOS recovery.
• A series of continuous beeps indicates a failed BIOS recovery.
7. If recovery fails, return to step 1 and repeat the recovery process.
8. If recovery is successful, turn off the computer, and disconnect its power cord.
9. Remove the computer cover and continue with the following steps.
10. On the jumper block (J9G1), reinstall the jumper back on pins 1-2 as shown below to set
normal mode for Setup.

Board Connectors
The 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 connectors
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.

The BIOS beep codes are listed in Table 33. The BIOS also issues a beep code (one long tone
followed by two short tones) during POST if the video configuration fails (a faulty video card or
no card installed) or if an external ROM module does not properly checksum to zero.

Intel Desktop Boards D845HV and D845WN Product Guide
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.
