paths, and data paths for transfer s b etween the pro cessor’s host bus, P CI
bus, Accelerated Graphics Po rt ( AGP), and main memory.
Intel 82371EB PCI ISA IDE Xcelerator (PIIX4E) implements the
PCI-to-ISA bridge, PCI IDE functionality, Universal Serial Bus (USB)
host/hu b func tion s , and enhanced p ower manageme nt.
The high-bandwidth PCI local bus eliminates data bottlenecks found in
t ra ditio na l syst ems, mainta ins maximum performance at high clock speeds, and
provides a clear upgrade path to future technologies.
The PCI bus contains two embedded PCI devices: the PCI local bus IDE
interface and the PCI video/graphics co nt roller. The PCI bus also cont ains a
co nnector for attachin g the bus exp ansion board.
Expansion Bus
The expansion bus co nt ains one ISA slot, three PCI slot s, o ne PCI/ I S A slot, and
one AGP video slot. The PCI ISA IDE Xcelerator chip (PIIX4E) provides t he
logic that enables the ISA bus fu nct ions. Wit h 24-bit memory address ing, a
16-bit data path, and an 8-MHz clock, the ISA bus is designed to support all
peripherals compatible with the IBM® AT™ standard. For PCI functions, the
Xcelerator chip provides 32-bit memory addressing, 32-bit data path, and a
33-MHz clock speed.
BIOS
The BIOS (Basic Input Outp ut System) is st or ed in the Flash EPROM. T he
Flash EPROM is reprogrammable and allows fast, economical BIOS upgrades.
The syste m memo r y map is sho w n in the fo llo w in g t ab le.

Plug and Play Support
The system comes with Plug and Play BIOS technology. Plug and Play
eliminates complicated setup procedures for installing Plug and Play expansion
boards.
To add a Plug and Play expansion board, simply power off the system, install
the board, and power on the system. There are no jumper s t o set and no s yst em
resource conflicts to reso lve. P lug and Play automatical ly configures the board
for the system. The system also supports non-Plug and Play boards.

UMB)
(open to ISA and PCI bus)
Plug and Play is controlled by the Plug and Play BIOS and the system’s
operating syste m. The Plug and Play BIOS is sto r ed in the Flash EPROM on the
system board.
The Plug and Play BIOS adds several steps to the POST process. During POST,
the Plug and Play evaluates the configuration of installed boards and assigns
available system resour ces to the devices. On co mpletion of Plug and Play
POST, the operat ing syste m checks to see if there are any additional resources
required, then assigns avai lable resources to the devices.
CMOS Memory/Real-Time Clock Battery
The 82371EB PCI ISA IDE Xcelerator (PIIX4E) on the system board stores
system in formation in no n-volat ile CMOS memory. T he chip also c ont a ins the
system’s real-time clock . Both are maintained b y a 3-volt coin cell lithium
battery on the system boar d. The battery is replaceable.
DMA/IRQ Settings
The system auto mat ically configures, with minimal user intervent ion, interr u pt
requests (IRQ), direct memory access (DMA) channels, and other parameters
when adding PCI boards.
The following tables list system IRQ and DMA default settings.

IDE Ports
The system board pro vides two fast I DE ports: primary channel and secondary
channel.
Each port supports two devices for a total of four IDE devices. The system
board allows the connect ion of an IDE CD- ROM dr ive for syst em configuration
flexibility without the addition of a controller.
The IDE ports feature an enhanced IDE interface which supports up to 16.7 MB
per second 32-bit wide data tr ansfers on t he high-performance PCI local bus.
The standard hard drive and Zip® drive (in some systems) are connected to the
primary channel. The CD-ROM drive is att ached t o t he seco ndar y channel.
I/O Ports
The system board features an enhanced para llel port , two bu ffered high-speed
serial ports, and two U niversal Serial Bus (USB) ports.
The enhanced parallel port supports Enhanced Capabilities Port (ECP) and
Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP
protocols. These protocols allow high-speed bi-directional transfer over a
parallel port and increase parallel port functionality by supporting more devices.
The two buffered high-speed serial ports use a fast 16C550 UART which
supports transfer rates up to 115.2 kilobits (Kb) per second. These ports allow
the installat ion of high-speed serial devices for faster dat a transfer rates.
The two USB ports allow additional new plug and play serial devices without
removing the system cover. Simply plug the USB device into the port. The
