This equipment has been tested and found to comply with the li m i ts for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protecti on agai nst harmful interference in a residential
installation. This equi pm ent generates, uses, and can radiate radio frequency energy and, if not i nstalled and used in
accordance with the inst ructions, may cause harmful interference to radio com m unications. However, there i s no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, whi ch can be determined by turning the equipm ent off and on, the user is encouraged t o try to correct
the interference by one or more of t he f ollowing measures:
• Reorient or relocate the receivi ng antenna.
• Increase the separation between t he equi pm ent and the receiver.
• Connect the equipment to an outlet on a circuit other than the one to which the receiver is connected.
• Consult the dealer or an experienced radio/ TV technician for help.
Canadian Department of Communications Compliance Statement:
This digital apparatus does not exceed the Class B limi t s for radio noise emissions from digital apparatus set out i n the
Radio Interference Regulations of the Canadian Department of Communications.
Le présent appareil numerique német pas de bruits radioélectriques dépassant l es limites applicables aux appareils
numériques de la classe B pres crites dans le Réglement sur le broul l age radi oélectrique édicté par le ministére des
Communications du Canada.

1.0 compliant)
Real-Time Clock
The desktop board has a time-of-day clock and 100-year calendar that will roll over to 2000 at the
turn of the century. A battery on the desktop 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 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 desktop boards, see the Intel
Web site at:
http://support.intel.com/support/year2000/index.htm
15
Intel Desktop Board CA810E Product Guide
USB Support
The desktop board has two USB ports. 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 desktop board supports the standard universal host controller
interface (UHCI) and uses standard software drivers written to be compatible with UHCI.
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port may 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.
Expansion Slots
The desktop board has four PCI expansion slots.
Battery
A battery on the desktop board 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.
BIOS
The BIOS includes the POST, the BIOS Setup program, the PCI and IDE auto-configuration
utilities, and the video BIOS.
To upgrade the BIOS, see Chapter 3.
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.
16
Desktop Board 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 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.
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.
17
Intel Desktop Board CA810E 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. Network adapters that are PCI 2.2 compliant assert the wake-up
signal through the PCI bus signal PME# (pin A19 on the PCI bus connectors). The optional
onboard LAN subsystem also supports remote wake up using the PME# signal.
CAUTION
For Wake on LAN technology, the 5 V standby line for the power supply must be capable of
delivering at least 720 mA of current. Failure to provide adequate standby current when
implementing Wake on LAN technology can damage the power supply.
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 standby power indicator (located between the DIMM sockets and the 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 2 shows the location of the standby power LED.

this feature can damage the power supply.
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
