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 35.
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 D850EMD2 and D850EMV2 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

If the desktop board is used with an ACPI-aware operating system, the BIOS can provide ACPI
support. Otherwise, it defaults to APM support.
17
Intel Desktop Boards D850EMD2 and D850EMV2 Product Guide
Instantly Available Technology
CAUTION
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 desktop 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’s standby power indicator, shown in Figure 3 on page 18, 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.
CR7F1
OM13620
Figure 3. Location of the Standby Power Indicator
Power supplies used with these desktop boards 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.
18
Desktop Board Features
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 and follow the steps outlined below:
1. Note the total Desktop Board D850EMD2 or D850EMV2 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 (non-wake-enabled) row, the total of the number of
non-wake-enabled 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 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 18 for the location of the standby power indicator LED location). Failure to
do so could damage the memory and the desktop board.
The desktop 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
desktop board will not boot.
Incorrect insertion of a RIMM module or a CRIMM module in a RIMM connector can damage the
Desktop Boards D850EMD2 and D850EMV2.
The desktop 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 11. 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
(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 9).

Intel Desktop Boards D850EMD2 and D850EMV2 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 10).

Installing and Replacing Desktop Board Components
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, 40-conductor 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 desktop board (see Figure 13, A).
• Attach the cable end with the two closely spaced connectors to the drives (see Figure 13, B).

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.

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.
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) 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 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.
