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.

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.

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:

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
the location of the Wake on LAN technology connector on the board.
Instantly Available 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.
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.

CAUTION
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
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

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
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
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.

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.
