BIOS Features
The BIOS, from American Megatrends, Inc.
(AMI), provides ISA and PCI compatibility. The
BIOS is contained in a Flash memory device
soldered to the motherboard. The BIOS
provides the POST, the Setup program, a PCI
and IDE auto-configuration utility, and BIOS
recovery code.
PCI Auto-configuration
The PCI auto-configuration utility works in
conjunction with the Setup program to support
using PCI add-in cards in the computer. When
you turn on the power after installing a PCI card,
the BIOS automatically configures interrupts,
DMA channels, and I/O space. Since PCI add-in
cards use the same interrupt resources as ISA
add-in cards, you must specify the interrupts
used by ISA cards in the Setup program. The

PD440FX Motherboard Product Guide
11
1
PCI auto-configuration program complies with
version 2.1 of the PCI BIOS specification.
IDE Auto-configuration
The motherboard automatically detects installed
IDE devices and configures them for operation.
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. To obtain
the ICU, contact your computer supplier.
Security Features
The BIOS provides a password option that you
can enable through the Setup program (refer to
Chapter 2).
BIOS Upgrades
Because the BIOS is stored in a Flash memory
device, you can upgrade the BIOS without
having to disassemble the computer. The
upgrade can be done with a utility stored on a
diskette or hard disk or run over a network. To
upgrade the BIOS, see Appendix B.
Expansion Slots
The motherboard has two dedicated 16-bit
ISA/AT†-compatible and three dedicated
PCI-compatible expansion slots. Another
expansion slot is a combination slot that can be
used for either a PCI or an ISA card. This allows
you to install a maximum of six add-in cards.
Real-time Clock and CMOS
RAM
The I/O controller provides a real-time clock and
CMOS RAM. You can set the time for the clock
and the CMOS values by using the Setup
program described in Chapter 2.

Product Description
12

Battery
A battery on the motherboard keeps the clock
and values in CMOS RAM current when your
computer is turned off. To replace the battery,
see Chapter 3.
Speaker
An optional speaker is mounted on the
motherboard. The speaker provides audible
error code information (beep codes) during the
POST if the BIOS cannot use the video
interface. For beep code descriptions, see
Chapter 4.
✏NOTE
The board also has a connector for an
optional offboard speaker. To install an
offboard speaker, remove the jumper that
enables the onboard speaker (refer to
Chapter 5).
Fan Connectors
The motherboard has connectors for two fans.
For the locations and pinouts of the fan
connectors, see Chapter 5.
USB Interface Support
The USB ports permit the direct connection of
two USB peripherals without an external hub. If
more devices are required, an external hub can
be connected to either of the built-in ports. The
motherboard supports the standard universal
host controller interface (UHCI) and uses
standard software drivers that are UHCI-
compatible.
Features of the USB include:
• Support for self-identifying, hot-pluggable
peripherals
• Automatic device configuration
• Support for isochronous and asynchronous
transfers over the same set of wires
• Support for up to 127 physical devices
• Bandwidth and low latencies appropriate for
telephony, audio, and other applications
• Error handling and fault recovery built into
protocol

✏NOTE
Computers that have an unshielded cable
attached to the 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 shielded cable
that meets the requirements for full-speed
devices.
Audio Subsystem
The onboard audio subsystem is based on the
Yamaha OPL†family of single-chip audio
controllers (YM 715). The audio subsystem
provides the digital audio and analog mixing
functions needed for recording and playing
