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 <ESC> 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.”

• Two serial ports

• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP)

support

• Mouse and keyboard controller

• 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

14

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.

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:

http://support.intel.com/support/motherboards/desktop/

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 <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.

Intel Desktop Board D815EEA Product Guide

16

• 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).

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

18

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.

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 wake-

enabled 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.

• 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

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 <Enter>. 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 <Enter>.

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 <Esc> to view the POST messages.

5. To enter the BIOS Setup program, press <F2> when you see the message:

Press <F2> to Run SETUP

6. For proper operation, load the BIOS Setup program defaults. To load the defaults, press <F9>.

7. To accept the defaults, press <Enter>.

8. In Setup, enter the settings you wrote down before beginning the BIOS upgrade.

Intel Desktop Board D815EEA Product Guide

44

9. To save the settings, press <F10>.

10. To accept the settings, press <Enter>.

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.

1

3

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

3

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.

Intel Desktop Board D815EEA Product Guide

✏NOTE

The Setup menus described in this section apply to the D815EEA desktop board with BIOS

identifier EA81510A.86A. Desktop boards with other BIOS identifiers might have differences in

some of the Setup menu screens.

The BIOS Setup program can be used to view and change the BIOS settings for the computer. The

BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST)

memory test begins and before the operating system boot begins. The menu bar is shown below.

Regulatory and Integration Information

81

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

82

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.
