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 <Enter> 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.

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.

For Instantly Available 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.

CA810 Motherboard Product Guide

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from either the APM sleep mode or the ACPI S1 state

• Requires only one call to access the computer

• Detects incoming call similarly for external and internal modems; does not use the Wake on

Ring connector

• Requires modem interrupt be unmasked for correct operation

Battery

A battery on the motherboard keeps the clock and the values in CMOS RAM current when your

computer is turned off. See Chapter 2 for instructions on how to replace the battery.

How to Install a Motherboard Support Standoff

The CA810 motherboard fits in a microATX chassis, but it can also be installed in a standard ATX

chassis. When it is installed in a standard ATX chassis, one of the motherboard support positions

might not have a corresponding standoff in the chassis. The following steps describe how to install

an additional standoff in a standard ATX chassis and how to secure the motherboard to this added

standoff. The Figure 5 shows the standoff (B), its associated adhesive pad (C), and a standoff

retention pin (A).

OM08553

Figure 5. Motherboard Support Standoff in a Standard ATX Chassis

Do the following steps to install the added standoff for the motherboard:

1. Trial fit the added standoff (B) in the motherboard (in the position indicated in Figure 5), then

position the motherboard in the ATX chassis on the existing standoffs, noting the required

mounting location for the new standoff in the chassis.

2. Remove the motherboard, clean the mounting location, then remove the protective paper

covering the adhesive (C) at the base of the added standoff (B).

3. Remount the motherboard in the chassis and press down on the added standoff (B) until the

adhesive secures it to the chassis.

4. When final fitting the motherboard into the chassis, position the motherboard at the same

height on the added standoff (B) as the other standoffs. Press the standoff retention pin (A)

into the added standoff to lock the motherboard at that height.

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.

Installing and Replacing Motherboard Components

Figure 12 shows the location of the DIMM sockets.

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.

Installation Precautions

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.
