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 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.

Intel Desktop Boards D850MD and D850MV 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.

Desktop Board Features

LAN Subsystem (Optional)

For Instantly Available 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 using this feature can damage the power supply and/or affect ACPI S3 sleep state functionality.

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.

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 on page 19, 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

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 Table 4 on page 20 and follow the steps outlined below:

1. Note the total D850MD or D850MV 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 non-wakeenabled devices installed (PCI and AGP) multiplied by the standby current requirement.

5. Add all additional wake-enabled devices’ and non-wake-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 3 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 D850MD and D850MV boards.

Installing Memory

The board has four memory module sockets arranged as bank 0 and bank 1. The pair of sockets closest to the processor is for bank 0, as shown in Figure 13. The memory module requirements are listed in the Main Memory section on page 12.

When adding memory:

• Install a pair of RIMMs in the sockets in bank 0 first. The RIMMs must be the same speed (PC600 or PC800), size (64 MB, 128 MB, 256 MB, or 512 MB), and density (single- or double-sided).

• If the desired memory configuration has been achieved in bank 0, install CRIMMs in the sockets in bank 1 (see Figure 11).

128 MB RDRAM Bank 0 128 MB RDRAM

CRIMM Bank 1 CRIMM

Figure 11. RDRAM and CRIMM Installation

Intel Desktop Boards D850MD and D850MV Product Guide

• If memory is to be installed in bank 1, the RIMM modules to be installed must be the same size and density to each other and match the speed of the RIMM modules in bank 0. 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, 128 MB, 256 MB, or 512 MB could be used (see Figure 12).

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.

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 (see Figure 18, A).

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.

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.

Place Battery Marking

There is insufficient space on this desktop board to provide instructions for replacing and disposing of the Lithium ion coin cell battery. For system safety certification, the following statement or equivalent statement is required to be permanently and legibly marked on the chassis near the battery.

CAUTION

Risk 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.
