Desktop Board Features

Real-Time Clock

The Real-Time Clock (RTC) is integrated into the chipset. The RTC provides battery backed-up date and time keeping device with two banks of static RAM with 128 bytes each. A battery on the 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) to read 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.

Intel Desktop Board D850GB/D850GBAL Product Guide

USB Support

The board has two USB ports. Two additional ports may be connected to a header on the board. 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 board supports the standard 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.

Desktop Board Features

Accelerated Graphics Port (AGP)

NOTE

✏

The board is only compatible with 1.5 V AGP cards.

The AGP is a high-performance bus 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 AGP 4X and 2X add-in cards. The AGP card retention mechanism is used only with cards with retention notches (see Figure 3 on page 22). For information about installing the AGP card retention mechanism and an AGP card, see Chapter 2.

Communication and Networking Riser (CNR) (D850GB only)

Audio Subsystem (D850GBAL only)

The audio subsystem features the following:

• Intel 82801BA ICH2

• Analog Devices AD1881 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 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 Firmware Hub.

The BIOS can be updated by following the instructions in Section 3.

Intel Desktop Board D850GB/D850GBAL Product Guide

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.

• 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 (D850GBAL only)

The Network Interface Controller subsystem consists of the ICH2 (with integrated LAN Media Access Controller) and a physical layer interface device. Features include:

• PCI Bus Master interface

• CSMA/CD Protocol Engine

• Serial CSMA/CD unit interface that supports the following physical layer interface devices:  82562EM onboard LAN  82562ET/EM (10/100 Mbit/sec Ethernet) on CNR bus (D850GB only)  82562EH (1 Mbit/sec HomePNA

• PCI Power Management  Support APM  Supports ACPI technology  Supports Wake up from suspend state (Wake on LAN technology)

Enhanced Diagnostic LEDs

Four dual-colored enhanced diagnostic LEDs are located on the back panel. The LEDs report POST failures. See page 80 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 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.

Intel Desktop Board D850GB/D850GBAL Product Guide

Power Management Features

Power management is implemented at several levels, including:

• Software support:  Advanced Configuration and Power Interface (ACPI)  Advanced Power Management (APM)

• Hardware support:  Power connector  Fan connectors  Wake on LAN technology  Instantly Available technology  Resume on Ring  Wake from USB  Wake from PS/2 keyboard  PME# wakeup support

If the board is used with an ACPI-aware operating system, the BIOS can provide ACPI support. Otherwise, it defaults to APM support.

Wake on LAN Technology

CAUTION

For Wake on LAN technology, the 5-V standby line for the power supply must be capable of delivering +5 V ± 5 % at 720 mA. Failure to provide adequate standby current when using this feature can damage the power supply.

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 1 on page 9 for the location of the Wake on LAN technology connector on the board.

Instantly Available Technology

CAUTION

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 2 on page 19, is lit when the memory modules and PCI bus connectors have power, even when the computer appears to be off.

Desktop Board Features

If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.

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. Calculate the standby current requirements using the steps described below.

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 3. 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 Table 3 and follow the steps outlined below:

1. Note the total D850GB/D850GBAL 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.

Intel Desktop Board D850GB/D850GBAL Product Guide

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.

Installing and Removing Memory

CAUTIONS

Before installing or removing RIMM modules, make sure that AC power has been removed by unplugging the power cord from the computer. The standby power indicator LED should not be lit (see Figure 2 on page 19) for the location of the standby power indicator LED location). Failure to do so could damage the memory and the board.

The board supports combinations of no more than 32 RDRAM components per RDRAM channel. If the total number of RDRAM components installed in all RIMM sockets exceeds 64, the computer will not boot.

A Continuity RIMM (CRIMM) module must be installed in any unused memory connector or the board will not boot.

Incorrect insertion of a RIMM module or a CRIMM module in a RIMM connector can damage the D850GB/D850GBAL board.

Installing Memory

The board’s memory module consists of four sockets arranged as bank 0 and bank 1. The pair of sockets closest to the processor is for bank 0, as shown in Figure 17. The memory module requirements are listed in the Main Memory section on page 11.

When adding memory:

• Install a pair of RIMMs in the sockets in bank 0 first. The RIMMs must be identical in speed, size, and density.

• If desired memory configuration has been achieved in bank 0, install CRIMMs in the sockets in bank 1.

• If memory is to be installed in bank 1, the RIMM modules to be installed must be identical in size and density to each other, and match the speed of the RIMM modules in bank 0. The RIMM modules do not, however, need to match those in bank 0 in size and density. For example, if bank 0 has two 128 MB RIMMs of PC800 RDRAM, bank 1 would require PC800 RDRAM also, however, any other supported RIMM modules such as 64 MB or 192 MB could be used.

• The BIOS detects the size and type of installed memory.

Installing and Replacing Desktop Board Components

OM10635

Figure 17. Installing a Memory Module

To install the memory modules, follow these steps:

1. Observe the precautions in “Before You Begin” (see page 21).

2. Holding the memory module by the edges, remove it from its antistatic package.

3. Make sure the clips at either end of the socket are pushed away from the socket.

4. Position the module above the socket. Align the two small notches in the bottom edge of the module with the keys in the socket.

5. Insert the bottom edge of the module into the socket.

6. When the module is seated, push down on the top edge of the module until the retaining clips snap into place. Make sure the clips are firmly in place.

Removing Memory

To remove a memory module, follow these steps:

1. Observe the precautions in "Before You Begin" (see page 21).

2. Turn off all peripheral devices connected to the computer. Turn off the computer. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).

3. Remove the computer cover.

4. Gently spread the retaining clips at each end of the socket. The memory pops out of the socket.

5. Hold the memory module by the edges, lift it away from the socket, and store it in an antistatic package.

6. Reinstall and reconnect any parts you removed or disconnected to reach the memory module sockets.

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 Instructions

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 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 D850GB/D850GBAL 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 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 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.
