Motherboard Features
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
Universal Serial Bus (USB) Support
The motherboard 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 motherboard supports the standard universal host controller
interface (UHCI) and takes advantage of standard software drivers written to be compatible with
UHCI. The USB features the following:
• Support for hot swapping Plug and Play devices
• Support for self-identifying peripherals
• Support for up to 127 physical devices
• Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications
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 high-speed USB device.
AGP
The AGP is a high-performance interconnect for graphics-intensive applications, such as 3D
graphics. AGP is independent of the PCI bus and is intended for exclusive use with graphical
display devices. AGP provides these features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for near 100 percent bus efficiency
• AC timing for 133 MHz data transfer rates, allowing real data throughput in excess of
500 MB/sec
12
SE440BX-2 Motherboard Product Guide
BIOS
The motherboard’s system BIOS is contained in a flash memory device on the motherboard. The
BIOS provides the power-on self test (POST), the BIOS Setup program, and the PCI and IDE autoconfiguration utilities.
The BIOS is always shadowed. Shadowing allows BIOS routines to be executed from fast 64-bit
onboard DRAM instead of from the slower 8-bit flash memory device.
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can upgrade the BIOS by using a
software utility on a diskette or hard disk, or over a network. For information on upgrading the
BIOS, see Chapter 4.
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.
However, PCI add-in boards use the same IRQ resources as ISA add-in boards. If you install both
a PCI and an ISA add-in board, you must specify the IRQ used by the ISA card. The PCI auto
configuration program complies with version 2.1 of the PCI BIOS specification.
IDE Auto Configuration
If you install an IDE device (e.g., 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.
ISA Plug and Play Capability
The motherboard provides auto configuration of Plug and Play ISA cards and resource
management for legacy (non-Plug and Play) ISA cards when used with the ISA Configuration
Utility (ICU) or a Plug and Play compatible operating system like Windows 95 and Windows 98.
To obtain the ICU, contact your computer supplier.
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 program and for booting the computer, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all the Setup options in
the Setup program. This is supervisor mode.
• The user password gives restricted access to view and change Setup options in the Setup
program. This is user mode.
13
Motherboard Features
• If only the supervisor password is set, pressing the <Enter> key 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 six expansion slots for installing add-in boards, like network cards, that
expand the capabilities of your computer. The expansion slots are as follows:
• One ISA slot
• One shared PCI/ISA slot
• Three PCI slots
• One AGP slot
Power Management
The motherboard supports two types of power management — Advanced Power Management
(APM) and Advanced Configuration and Power Interface (ACPI).
Advanced Power Management (APM)
APM’s energy saving standby mode can be initiated in the following ways:
• Specify a time-out period in Setup
• Press the suspend/resume switch connected to the front panel sleep connector
• Use an operating system option, such as the Suspend menu item in Windows 95 and
Windows 98
In standby mode, the motherboard can reduce power consumption by spinning down hard drives,
†
and reducing power to or turning off VESA
mode can be enabled or disabled in Setup (see Chapter 3).
While in standby mode, the system retains the ability to respond to external interrupts and service
requests, such as incoming faxes or network messages. Any keyboard or mouse activity brings the
system out of standby mode and immediately restores power to the monitor.
The BIOS enables APM by default; but the operating system must support an APM driver for the
power-management features to work. For example, Windows 95 and Windows 98 support the
power-management features upon detecting that APM is enabled in the BIOS.
DPMS-compliant monitors. Power-management
14
SE440BX-2 Motherboard Product Guide
Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. ACPI requires an ACPI-aware operating system. ACPI features include:
• Plug and Play (including bus and device enumeration) and APM functionality normally
contained in the BIOS
• Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video monitor, and hard disk drives
• Methods for achieving less than 30-watt system operation in the Power On Suspend sleeping
state, and less than 5-watt system operation in the Suspend to Disk sleeping state
• A Soft-off feature that enables the operating system to power off the computer
• Support for multiple wake up events
• Support for a front panel power and sleep mode switch
Battery
A battery on the motherboard keeps the clock and the values in CMOS RAM current when your
computer is turned off. To replace the battery, see Chapter 2.
Wake on Ring
Wake on Ring enables the computer to wake from sleep or soft-off mode when a call is received
on a telephony device, such as a modem, configured for operation on Serial Port A. The first
incoming call powers up the computer. A second call must be made to access the computer. To
access this feature use the Wake on Ring connector. See Chapter 5 for the location and pinouts of
the Wake on Ring connector.
Wake on LAN Technology (Optional)
Wake on LAN technology enables remote wakeup of the computer through a network. Wake on
LAN technology requires a PCI add-in network interface card (NIC) with remote wakeup
capabilities. The remote wakeup connector on the NIC must be connected to the onboard Wake on
LAN technology connector. The NIC monitors network traffic at the MII interface; upon
†
detecting a Magic Packet
access this feature use the Wake on LAN technology connector. See Chapter 5 for the location and
pinouts of the Wake on LAN technology connector.
CAUTION
For Wake on LAN, 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,
±
can damage the power supply.
