Real-Time Clock
The motherboard has a time-of-day clock and 100-year calendar that will rollover to 2000 at the
turn of the century. A battery on the motherboard keeps the clock current when the computer is
turned off.

✏

NOTE
The recommended method of accessing the date in systems with Intel motherboards is indirectly
from the Real-Time Clock (RTC) via the BIOS. The BIOS on Intel motherboards and baseboards
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.
For more information on proper date access in systems with Intel motherboards please see:
http://support.intel.com/support/year2000/paper.htm

CA810 Motherboard Product Guide

USB Support
The motherboard has two USB ports. One of the USB ports can be routed to a front panel
connector. 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 motherboard 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 high-speed USB device.

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 can be upgraded by following the instructions in Section 3.

Intel® 82802AB Firmware Hub (FWH)
The BIOS is stored in the Intel 82802AB Firmware Hub. The firmware hub contains a nonvolatile
memory core based on Intel® flash technology. In addition to storing the system BIOS, the
firmware hub incorporates logic features such as a hardware random number generator (RNG).
These logic features enable protection for storing and updating platform information relating to
security and manageability.

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.

Motherboard Features

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 Setup
and for booting the computer, with the following restrictions:
•
•
•
•

The supervisor password gives unrestricted access to view and change all Setup options. This
is supervisor mode.
If only the supervisor password is set, pressing at the password prompt of the Setup
program 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.
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.

Expansion Slots
The motherboard has four PCI expansion slots.

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
 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.

CA810 Motherboard Product Guide

Wake on LAN Technology
The optional Wake on LAN technology connector can be used with PCI bus network adapters that
have a remote wake up connector, as shown in Figure 2. Network adapters that are PCI 2.2
compliant assert the wakeup signal through the PCI bus signal PME# (pin A19 on the PCI bus
connectors). The optional onboard LAN subsystem also supports remote wakeup using the PME#
signal.

Figure 2. Using the Wake on LAN Technology Connector

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 implementing
Wake on LAN technology can damage the power supply.

Motherboard Features

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 wake state.
The optional standby power indicator (located between the DIMM sockets and power connector)
provides an indication that power is still present to the DIMMs and PCI bus connectors, even when
the computer appears to be off. Figure 3 shows the location of the standby power LED.

How to Install Memory
You can install from 32 MB to 512 MB of memory in the DIMM sockets. The board has two
DIMM sockets arranged as banks 0 and 1. As shown in Figure 11 on page 26, the DIMM socket
closest to the processor is for bank 0. The motherboard supports the following memory features:

✏

NOTE
On the CA810 motherboard, the minimum memory required is 64 MB for the Windows NT 4.0
operating system.
For optimal video performance, it is recommended that 64 MB of memory be installed.
•

168-pin 3.3 V DIMMs with gold-plated contacts

•

100 MHz 4-clock unbuffered SDRAM DIMMs

•

Non-ECC (64-bit) memory

•

A minimum of 32 MB (required); a maximum of 512 MB. For optimal video performance,
use at least 64 MB of system memory.

•

Module sizes: 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, and 512 MB

•

DIMMs with Serial Presence Detect (SPD) or non-SPD data structure

CAUTION
Because the main system memory is also used as video memory, the CA810 motherboards require
100MHz SDRAM DIMMs even though the processor front side bus is 66 MHz. It is highly
recommended that SPD DIMMs be used, since this allows the chipset to accurately configure
memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt
to correctly configure the memory settings, but performance and reliability may be impacted.

CA810 Motherboard Product Guide

The motherboard supports single- or double-sided DIMMs in the following sizes:
DIMM Size

Non-ECC Configuration

16 MB

2 Mbit x 64

32 MB

4 Mbit x 64

64 MB

8 Mbit x 64

128 MB

16 Mbit x 64

256 MB

32 Mbit x 64

When adding memory, be aware that:
•
•
•

You can install DIMMs in either of the two banks. That is, if only one DIMM is being
installed, it can be placed in either DIMM socket.
You can use different sizes of DIMMs in different banks.
The BIOS detects the size and type of installed memory.

How to Connect IDE Drives
The Intel boxed motherboard package includes an IDE cable. It is capable of connecting two
drives to the motherboard.
The cable supports the Ultra ATA/66 interface and is backward compatible with drives using
slower IDE transfer protocols. If an Ultra ATA/66 drive and a drive using any other IDE
transfer protocol are attached to the same cable, the maximum transfer rate for either drive is
33 MB/second.
When building a system with both Ultra ATA/66 drives and slower drives, attach the
Ultra ATA/66 drives to one channel with the Ultra ATA/66 cable. Attach the slower drives
to the other channel with another cable.

When you install and test the motherboard, observe all warnings and cautions in the installation
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.

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 motherboard with a processor from the same family and operating at the same
(or higher) speed as the processor on this motherboard.
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 mismating of 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 motherboards now have PTCs on all
external ports that provide DC power externally.

CA810 Motherboard 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 motherboards 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 motherboard 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 motherboard 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.
