NOTE  
The D845HV and D845WN boards 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. The AGP card retention  
mechanism is used only with cards with retention notches (see Figure 12 on page 32). For  
information about installing the AGP card retention mechanism and an AGP card,  
see Chapter 2 on page 21.  
Communication and Networking Riser (CNR) (Optional)  
The optional CNR provides an interface that supports various features such as audio, modem,  
USB, and LAN.  
Audio Subsystem  
The audio subsystem features the following:  
Intel 82801BA ICH2  
Analog Devices AD1885 analog codec (AC 97)  
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 Intels 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:  
Basic 10/100 Ethernet LAN connectivity  
Supports RJ-45 connector with status indicator LEDs  
Programmable transit threshold  
Configurable EEPROM that contains the MAC address

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 boards 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 devicesand nonwake-enabled devicesstandby 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.

process or the system may not function.  
1. Boot the computer with the BIOS update diskette in drive A. During system boot, the  
AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update  
process.  
2. When the update process is complete, the monitor will display a message telling you to remove  
the diskette and to reboot the system.  
3. As the computer boots, check the BIOS identifier (version number) to make sure the update  
was successful. If a logo appears, press <Esc> to view the POST messages.

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 computers 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.  
1
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.

11. Leave the update diskette in drive A, replace the computer cover, and connect the computers  
power cord.  
12. Turn on the computer and continue with the BIOS update (see page 44).

1. Select the boot device with <> or <>.  
2. Press <Enter> to set the selection as the intended boot device.  
4th Boot Device Intel UNDI, PXE  
(Note 1)  
The operating system assigns a drive letter to each boot device in  
Disabled  
the order listed. Changing the order of the devices changes the  
drive lettering. The default settings for the first through final boot  
devices are, respectively listed below. The BIOS supports up to  
sixteen total boot devices in any combination of the boot device  
types below, with respect to these maximums per type.  
Removable Device (maximum of four).  
Hard Drive (maximum of 12).  
ATAPI CD-ROM (maximum of four).  
Intel® UNDI, PXE (maximum of five) (Note 2).  
The boot devices appear in order by type. For example, assume that  
the default boot order is preserved and that seven boot devices of  
the following types are installed on the system: two removable  
devices, two hard drives, two ATAPI CD-ROMs, and an Intel UNDI  
(Universal Network Device Interface), PXE device. Both removable  
devices would appear as the first and second boot devices, the two  
hard drives would appear as the third and fourth, the two ATAPI  
CD-ROM drives would appear as the fifth and sixth, and the Intel  
UNDI, PXE device would appear as the seventh boot device.  
Notes:  
1. After the predefined boot device types (removable devices, hard drives, and ATAPI CD-ROM drives), the entries in this  
list will reflect as many boot entry vector (BEV) boot devices (for example, Intel UNDI, PXE devices) and SCSI  
CD-ROM drives as are installed, up to the five BEV boot devices supported by the BIOS.  
2. While the predefined boot device types are individually listed in submenus by type, the BEV devices and SCSI  
CD-ROM drives are all listed at this level.

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.

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 suppliers 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.
