For the latest information on processor support for the board, refer to the Intel desktop board web
site at:
http://support.intel.com/support/motherboards/desktop/
For instructions on installing or upgrading the processor, see Chapter 2.

Main Memory
The board supports 168-pin SDRAM DIMMs as defined below:
• 168-pin SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated contacts
• Three DIMM slots are provided for flexible memory configurations
• 133 MHz SDRAM up to two double-sided DIMMs, or one double-sided DIMM and two
single-sided DIMMs
• 100 MHz SDRAM up to three double-sided DIMMs
• Minimum system memory: 32 MB
• Maximum system memory: 512 MB

✏

NOTE
The BIOS cannot determine DIMM size or type when not initialized. If more than 512 MB system
memory is installed, the BIOS displays a message at boot indicating some memory above 512 MB
has not been initialized. The message indicates additional information is available in Setup. The
first time BIOS detects this condition, a pause follows the message with the option to enter Setup or
to and continue to boot. The message continues to be displayed at boot time as long as the
condition exists, however, the BIOS will not pause on subsequent detection. Setup displays the
installed memory configuration and shows memory above 512 MB as “not initialized.”

Desktop Board Features

Input/Output (I/O) Controller
The SMSC LPC47M102 I/O controller features the following:
• Two serial ports
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP)
support
• Mouse and keyboard controller
• Diskette drive controller
• MIDI/Game port
• Fan control

Real-Time Clock
The desktop board has a time-of-day clock and 100-year calendar. A battery on the desktop board
keeps the clock current when the computer is turned off.

✏

NOTE
The recommended method of accessing the date in systems with Intel desktop boards is indirectly
from the Real-Time Clock (RTC) via the BIOS. The BIOS on Intel desktop boards contains a
century checking and maintenance feature that checks the least two significant digits of the year
stored in the RTC during each BIOS request (INT 1Ah). This reads the date and, if less than 80
(i.e., 1980 is the first year supported by the PC), updates the century byte to 20. This feature
enables operating systems and applications using the BIOS date/time services to reliably
manipulate the year as a four-digit value.

USB Support
The desktop board has two rear panel USB ports. Front panel USB support is available as an
option to provide an additional two USB ports. You can connect two USB peripheral devices
directly to the computer without an external hub. To attach more than two devices, connect an
external hub to either of the built-in ports. The desktop board supports the universal host
controller interface (UHCI) and takes advantage of standard software drivers written to be
compatible with UHCI.

✏

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.

Intel Desktop Board D815EEA Product Guide

PCI Enhanced IDE Interface
The PCI enhanced IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega ZIP† drives inside the computer.
The interface supports:
• Up to four IDE devices (such as hard drives)
• ATAPI devices (such as CD-ROM drives)
• PIO Mode 3 and PIO Mode 4 devices
• Ultra ATA/33, Ultra ATA/66, and Ultra ATA/100 protocols
• Support for laser servo (LS-120) drives

Expansion Slots
The desktop board has seven add-in board connectors: five PCI expansion slots, one AGP
universal connector, and one CNR connector. The seven connectors support only six expansion
cards because the CNR slot and PCI slot 5 are shared and cannot be used simultaneously.

Accelerated Graphics Port (AGP)
The 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 use with graphical display devices. The
AGP universal connector supports AGP 1X, 2X, and 4X. The AGP universal connector also
supports GPA and DVI add-in cards.
An AGP card retention mechanism (RM) is included with the boxed desktop board. Installation
instructions are presented in Chapter 2.

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 Intel 82802AB
Firmware Hub.
The BIOS can be upgraded by following the instructions in Chapter 3.

PCI Auto Configuration
If you install a PCI add-in board 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 board. You do not need to run the BIOS Setup program after you install a PCI add-in
board.

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.

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 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.

Intel Desktop Board D815EEA Product Guide

•

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.

Diagnostic LEDs
Four dual-colored diagnostic LEDs are located on the back panel. The LEDs report POST failures.
See page 74 for information about the LEDs.

Speaker
A 47 Ω inductive speaker is mounted on the desktop board. The speaker provides audible error
code (beep code) information during the Power-On Self-Test (POST).

LAN Subsystem
The Intel 82562ET (in conjunction with the Intel 82801BA ICH2) provides a Fast Ethernet Wired
for Management (WfM) PCI LAN subsystem providing both 10Base-T and 100Base-TX
connectivity. Features include:
• 32-bit, 33-MHz direct bus mastering on the PCI bus
• Shared memory structure in the host memory that copies data directly to/from host memory
• 10Base-T and 100Base-TX capability using a single RJ-45 connector with connection and
activity status LEDs
• IEEE 802.3u Auto-Negotiation for the fastest available connection
• Jumperless configuration; the LAN subsystem is completely software configurable

Intel® 82562ET Platform LAN Connect Device (Optional)

Battery
A battery on the desktop board keeps the values in CMOS RAM and the clock current when the
computer is turned off. See Chapter 2 for instructions on how to replace the battery.

Power Management Features
Power management is implemented at several levels, including:
• Software support:
 Advanced Power Management (APM)
 Advanced Configuration and Power Interface (ACPI)
• Hardware support:
 Wake on LAN technology
 Instantly Available technology
 Wake on Ring
 Resume on Ring
If the board is used with an ACPI-aware operating system, the BIOS can provide ACPI support.
Otherwise, it defaults to APM support.
The BIOS supports ACPI provided the operating system is ACPI-aware. Otherwise, the BIOS
defaults to APM.

Intel Desktop Board D815EEA Product Guide

Wake on LAN Technology
The Wake on LAN technology connector can be used with PCI bus network adapters that have a
remote wake-up connector. Network adapters that are PCI 2.2 compliant assert the wake-up signal
using the PCI bus signal PME# (pin A19 on the PCI bus connectors). See Figure 22 on page 67 for
the location of the Wake on LAN technology connector on the desktop board.

CAUTION
For Wake on LAN technology, the 5-V standby line for the power supply must be capable of
providing adequate +5-V standby current. Failure to provide adequate standby current when
implementing Wake on LAN technology can damage the power supply.

Instantly Available Technology
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 desktop board standby power indicator, shown in Figure 2 on page 18, is lit when the memory
modules and PCI bus connectors have power, 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. For more information about front panel LED states, see the Intel ® Desktop
Board D815EEA Technical Product Specification.

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, etc.
Calculate the standby current requirements using the steps described below.
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 as outlined in Table 6.
Some values are set per specifications such as PCI 2.2. The values given in the table for Instantly
Available are for a system containing a single wake-enabled PCI (or AGP) device and five
non-wake devices. Actual measurements may vary.

Estimating Standby Current
CAUTION
Power supplies used with the board must provide enough standby current to support the 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 board
may lose register settings stored in memory and may not awaken properly.
To estimate the standby current required for a specific system configuration, the standby current
requirements of all installed components must be combined. Refer to Table 6 and follow these
steps:
1. List the board’s standby current requirement (767 mA).
2. List the PS/2 ports’ standby current requirement (see note).
3. List, from the AGP and PCI 2.2 slots (wake enabled devices) row, the total number of wakeenabled devices installed and multiply by the standby current requirement.
4. List, from the AGP and PCI 2.2 slots (non-wake enabled devices) row, the total number of
wake-enabled devices installed and multiply by the standby current requirement.
5. List all additional wake enabled devices’ and non-wake enabled devices’ standby current
requirements as applicable.
6. Add all the listed standby current totals from steps 1 through 5 to determine the total estimated
standby current power supply requirement.

• Five non wake-enabled devices @ 20 mA each
PS/2 Ports requirements per the IBM PS/2 Port Specification (Sept 1991):
• Keyboard @ 275 mA (Actual measurements are 220 mA-300 mA, depending on the type of
keyboard and the operational state of the keyboard’s LEDs.)
• Mouse @ 70 mA
USB requirements are calculated by totaling the following:
• One wake-enabled device @ 500 mA
• Three USB non-wake-enabled devices @ 2.5 mA each
The USB ports are limited to a combined total of 700 mA.
CNR requirements are calculated as follows:
• One wake-enabled device @ 375 mA
• Non wake-enabled devices @ 20 mA

Desktop Board Features

Wake on Ring
The operation of Wake on Ring can be summarized as follows:
• Powers up the computer from the APM soft-off mode.
• Requires two calls to access the computer:

•

 The first call powers up the computer.
 The second call enables access (when the appropriate software is loaded).
Detects incoming call differently for external as opposed to internal modems:
 For external modems, hardware on the desktop board monitors the ring indicate (RI) input
of serial port A (serial port B does not support this feature).
 For internal modems, a cable must be routed from the modem to the Wake on Ring
connector.

See Figure 22 on page 67 for the location of the Wake on Ring connector on the desktop board.

Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from either the APM sleep mode or the ACPI S1 state
• Requires only one call to access the computer
• Detects incoming call similarly for external and internal modems; does not use the Wake on
Ring connector
• Requires modem interrupt be unmasked for correct operation

1. Obtain the BIOS upgrade file through your computer supplier or from the Intel World Wide
Web site:
http://support.intel.com/support/motherboards/desktop/
2. Copy the BIOS upgrade file to a temporary directory on your hard disk.
3. Change to the temporary directory.
4. To extract the files, double click on the BIOS upgrade file, for example, CCBIOSxx.EXE.
5. One of the extracted files is MK_BOOTZ.EXE. Double click on this file to extract the
README.TXT file.
6. Follow the directions in the README.TXT file.

Upgrading the BIOS

Creating a BIOS Upgrade Diskette
1. Obtain the BIOS upgrade file through your computer supplier or from the Intel World Wide
Web site:
http://support.intel.com/support/motherboards/desktop/
2. Copy the BIOS upgrade file to a temporary directory on your hard disk.
3. From the C:\ prompt, change to the temporary directory.
4. To extract the file, type the name of the BIOS upgrade file, for example, CCBIOSxx.EXE.
5. Press . The extracted file contains the following files:
LICENSE.TXT
BIOINSTR.TXT
BIOS.EXE
MK_BOOTZ.EXE
6. Read the LICENSE.TXT file, which contains the software license agreement, and the
BIOINSTR.TXT file, which contains the instructions for the BIOS upgrade.
7. Insert the bootable diskette into drive A.
8. To extract the BIOS.EXE file to the diskette, change to the temporary directory that holds the
BIOS.EXE file and type:
BIOS A:

9. Press .
10. The diskette now holds the new BIOS files, the Intel Flash Update Utility, and the recovery
files.

Upgrading the BIOS
CAUTION
The AUTOEXEC.BAT file provided with the update files updates the BIOS in two parts: first
updating the boot block and displaying the Operation completed successfully message
and second, updating the BIOS core. You will be asked to reboot the system when the update
process is complete. Do not interrupt the process or the system may not be capable of rebooting.
1. Boot the computer with the BIOS upgrade diskette in drive A. During system boot, the
AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update
process.
2. The AUTOEXEC.BAT file updates the BIOS in two parts: first updating the boot block and
displaying the Operation completed successfully message and then updating the
BIOS core.
3. When the update process is complete, the monitor will display a message telling you to remove
the diskette and to reboot the system.
4. As the computer boots, check the BIOS identifier (version number) to make sure the upgrade
was successful. If a logo appears, press to view the POST messages.
5. To enter the BIOS Setup program, press when you see the message:
Press to Run SETUP

6. For proper operation, load the BIOS Setup program defaults. To load the defaults, press .
7. To accept the defaults, press .
8. In Setup, enter the settings you wrote down before beginning the BIOS upgrade.

Intel Desktop Board D815EEA Product Guide

9. To save the settings, press .
10. To accept the settings, press .
11. Turn off the computer and reboot.

Recovering the BIOS
It is unlikely that anything will interrupt the BIOS upgrade, however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover the BIOS if an upgrade fails.
The following procedure uses recovery mode for the Setup program. See page 38 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 (J7B1) (see Figure 19).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.
3
1

4. Insert the bootable BIOS upgrade 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. Listen to the speaker and watch for
drive A activity.)
• 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 successful
BIOS recovery has taken place.
• A series of continuous beeps indicates that BIOS recovery has failed.
6. If recovery fails, return to step 1 and repeat the recovery process.
7. If recovery is successful, turn off the computer, and disconnect its power cord.
8. Remove the computer cover and continue with the following steps.
9. On the jumper block (J7B1), reinstall the jumper back on pins 1-2 as shown below to set
normal mode for Setup.

1

10. Leave the upgrade diskette in drive A, replace the computer cover, and connect the computer’s
power cord.
11. Turn on the computer and continue with the BIOS upgrade (see page 43).

4 Using the Setup Program
You can use the BIOS Setup program to change the configuration information and boot sequence
for the computer. This chapter tells you how to access the BIOS Setup program and lists Setup
features, options, and default settings.

✏

NOTE
For reference purposes, you should write down the current Setup settings. When you make
changes to the settings, update this record.

BIOS Setup Program Modes
The BIOS Setup program has three modes of operation:
• Normal mode for normal operations
• Configure mode for clearing passwords (See Chapter 2 for instructions)
• Recovery mode for BIOS recovery
The BIOS Setup Program Operating mode is controlled by the setting of the configuration jumper
block. The jumper is set to normal mode at the factory.

Installation Precautions
When you install and test the desktop board, observe all warnings and cautions in the installation
instructions.
To avoid injury, be careful of:
• Sharp pins on connectors
• Sharp pins on printed circuit assemblies
• Rough edges and sharp corners on the chassis
• Hot components (like processors, voltage regulators, and heat sinks)
• 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.

WARNING
Do not open the power supply. Risk of electric shock and burns from high voltage and rapid
overheating. Refer servicing of the power supply to qualified technical personnel.

Regulatory and Integration Information

Installation Requirements
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)
Before computer integration, make sure that the power supply and other modules have passed
EMC testing using a desktop board with a processor from the same family and operating at the
same (or higher) speed as the processor on this desktop board.
In the installation instructions for the host chassis, power supply, and other modules pay close
attention to the following:
•
•
•
•

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 have not passed applicable EMC testing before integration,
EMC testing must be conducted on a representative sample of the newly completed computer.

Ensure Chassis and Accessory Module Certifications
Make sure that the chassis, any added subassembly, such as a board or drive assembly, and internal
or external wiring, are certified for the region(s) where the end product will be used. Marks on the
product are proof of certification. Certification marks are as follows:
In Europe
The CE marking signifies compliance with all relevant European requirements. If the chassis does
not bear the CE marking, obtain a supplier’s Declaration of Conformity to the appropriate
standards required by the European EMC Directive and Low Voltage Directive. Other directives,
such as the Machinery and Telecommunications Directives, might also apply depending on the
type of product. No regulatory assessment is necessary for low voltage DC wiring used internally
or wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is provided by a maximum 8 A current limiting circuit, or a maximum 5 A fuse, or
Positive Temperature Coefficient (PTC) resistor. All Intel desktop boards now have PTCs on all
external ports that provide DC power externally.

Intel Desktop Board D815EEA Product Guide

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. External wiring must be UL Listed and
suitable for the intended use. Internal wiring must be UL Listed or Recognized and rated for
applicable voltages and temperatures. The FCC mark (Class A for commercial or industrial only
or Class B for residential) signifies compliance with electromagnetic interference requirements.
In Canada
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety
requirements. No regulatory assessment is necessary for low voltage DC wiring used internally or
wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is provided by a maximum 8 A current limiting circuit, or a maximum 5 A fuse, or
positive temperature coefficient (PTC) resistor. All Intel desktop boards now have PTCs on all
external ports that provide DC power externally.

Prevent Power Supply Overload
Unless the power supply has inherent overcurrent protection, do not overload the power supply
output. To avoid overloading the power supply, make sure that the calculated total current load of
all the modules within the computer is less than the output current rating of the power supply. If
you do not do this, the power supply could overheat, catch fire, or damage the insulation that
separates hazardous AC line circuitry from low-voltage user accessible circuitry. If the load drawn
by a module cannot be determined by the markings and instructions supplied with the module,
contact the module supplier’s technical support.

Place Battery Marking on the Computer
There is insufficient space on this desktop board to provide instructions for replacing and
disposing of the battery. The following warning must be placed permanently and legibly on the
chassis as near as possible to the battery.

WARNINGS
Danger of explosion if battery is incorrectly replaced.
Replace with only the same or equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer’s instructions.

Use Only for Intended Applications
This desktop board was evaluated for use in computers that will be installed in offices, homes,
schools, computer rooms, and similar locations. The suitability of this product for other
applications, (such as medical, industrial, alarm systems, and test equipment) might require further
evaluation.
