write-through organization.
The system comes with 32 to 256 MB of main system memory. Two sockets on
the system board support up to 256 MB of high-speed memory using industry-
standard gold-plated dual in-line memory modules (DIMMs).
The system supports 66-MHz Synchronous DRAM (SDRAM) only.
The system supports the following DIMM configurations:
 1-Mbit by 64 (8-MB DIMM)
 2-Mbit by 64 (16-MB DIMM)
 4-Mbit by 64 (32-MB DIMM)
 8-Mbit by 64 (64-MB DIMM)
 16-Mbit by 64(128-MB DIMM).
Chipset
The Intel 440EX chipset provides DMA, memory, and bus control. The chipset
includes the following chips:
 Intel 82443EX PCI/AGP (PAC) provides bus-control signals, address
paths, and data paths for transfers between the processor’s host bus, PCI
bus, Accelerated Graphics Port (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/hub functions, and enhanced power management.
PCI Local Bus
The 32-bit industry-standard PCI bus is a highly-integrated input/output (I/O)
interface that offers the highest performance local bus available for the Pentium
II processor. The PCI bus supports burst modes that send large chunks of data
across the bus, allowing fast displays of high-resolution images.
The high-bandwidth PCI local bus eliminates data bottlenecks found in
traditional systems, maintains 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 controller. The PCI bus also contains a
connector for attaching the bus expansion board.

1-4 Technical Information
Expansion Bus
The expansion bus contains one ISA slot and two PCI slots. The PCI ISA IDE
Xcelerator chip (PIIX4E) provides the logic that enables the ISA bus functions.
With 24-bit memory addressing, a 16-bit data path, and an eight 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 Output System) is stored in the Intel 28F002 Flash
EPROM. The Flash EPROM is reprogrammable and allows fast, economical
BIOS upgrades.
The system memory map is shown in the following table.
System Memory Map
Memory Address Size Function
100000-18000000 383 MB Extended memory
E8000-FFFFF 96 KB System BIOS
E0000-E7FFF 32 KB System BIOS (available as
UMB)
C8000-DFFFF 96 KB Available high DOS memory
(open to ISA and PCI bus)
A0000-C7FFF 160 KB Video memory and BIOS
00000-9FFFF 640 KB Conventional memory
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 jumpers to set and no system
resource conflicts to resolve. Plug and Play automatically configures the board
for the system. The system also supports non-Plug and Play boards.
Plug and Play is controlled by the Plug and Play BIOS and the system’s
operating system. The Plug and Play BIOS is stored in the Intel 28F002 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 resources to the devices. On completion of Plug and Play
POST, the operating system checks to see if there are any additional resources
required, then assigns available resources to the devices.

Technical Information 1-5
CMOS Memory/Real-Time Clock Battery
The 82371EB PCI ISA IDE Xcelerator (PIIX4E) on the system board stores
system information in non-volatile CMOS memory. The chip also contains the
system’s real-time clock. Both are maintained by a 3-volt coin cell lithium
battery on the system board. The battery is replaceable.
DMA/IRQ Settings
The system automatically configures interrupts requests (IRQ), direct memory
access (DMA) channels, and other parameters when adding PCI boards with
minimal user intervention.
The following tables list system IRQ and DMA default settings.

IDE Ports
The system board provides two fast IDE ports: primary channel and secondary
channels.
Each port supports two devices for a total of four IDE devices. The system
board allows the connection of an IDE CD-ROM drive for system 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 transfers on the 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 attached to the secondary channel.
I/O Ports
The system board features an enhanced parallel port, one buffered high-speed
serial port, and two Universal 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 one buffered high-speed serial port uses a fast 16C550 UART which
supports transfer rates up to 115.2 kilobits (Kb) per second. This port allows the
installation of high-speed serial devices for faster data 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
speed varies between 12 megabits per second (Mbps) for printers and 1.5 Mbps
for mice and keyboards. Up to 127 USB devices can be connected to the
computer.
The combination of the enhanced parallel port, buffered serial ports, and USB
ports ensure optimum performance for future peripheral devices and operating
systems.

CD-ROM/DVD Drive
The drive can be used to load programs from a CD or it can be used to play
audio CDs. The drive operates at different speeds depending on whether the CD
contains music or data. The drive is fully compatible with Kodak Multisession
Photo CDs™ and standard CDs.
The drive is connected to the secondary IDE/PCI port on the system board.
Zip Drive
Some systems come with the Iomega®Zip 100 ATA drive. The Zip drive
provides removable 100-MB data disks and has a data transfer rate up to 1.4 MB
per second.
Power Supply
The 235-watt power supply is mounted inside the system unit. It supplies power
to the system board, option boards, diskette drives, hard drives, keyboard, and
mouse. A fan inside the power supply provides system ventilation. The power
supply has several cables for attaching to the various devices requiring power.
Power Management
The Advanced Power Management (APM) program, located on the 82371EB
PCI ISA IDE Xcelerator (PIIX4E) chip, reduces system power consumption
when there is no activity detected from the keyboard, mouse, diskette drive,
CD-ROM/DVD drive, or hard drive after a predefined period of time. As soon
as activity is detected, the system resumes where it left off.
In the CMOS Setup utility, an inactivity timer is available for setting the length
of time before the system enters a low-power mode.

2-2 Setup Utility
This section describes the Setup utility program that allows the system
configuration information to be viewed and changed.
Note:
The system ships from the factory with the correct
system parameters for the configuration. Unless setting the
time and date, setting security features, customizing the
system, or adding optional hardware, Setup does not need
to be run.
Configuration Information
System configuration information is stored in nonvolatile memory. A
nonvolatile memory device retains its data when system power is turned off.
Nonvolatile memory is a complementary metal-oxide semiconductor (CMOS)
chip backed up by a battery on the system board. The battery supplies
continuous power to CMOS memory and maintains configuration information
when system power is off.
When to Use Setup
The Setup utility allows the user to view and set system parameters. Use the
Setup utility program:
 to set the time and date.
 to update or check system parameters when adding or removing
expansion options.
 to change or set power management features.
 to correct a hardware discrepancy when the Power-On Self-Test (POST)
displays an error message and a prompt to run Setup.
 to check the installation of optional memory by comparing the amount of
memory installed with the amount of memory displayed by Setup.
 to change certain system operating parameters, such as boot device
sequence and keyboard parameters.
 to configure system connections for peripherals such as the diskette drive,
hard drives, and devices connected to the printer port and serial port.
 to customize the system with security features such as passwords.
 to set system parameters after replacing the CMOS battery.

How to Start Setup
To start the Setup utility, follow these steps:
1. Turn on or reboot the system.
2. Press F2 after POST begins, but before the system boots up. You have about
five seconds to press F2.
Setup’s Main Menu window appears similar to the following screen.
Note:
The screen shown is typical of a system. The
actual settings on the Main Menu depend upon the hardware
installed in the system.
How to Use Setup
The Setup utility has a Main Menu window and six top-level menus with
submenus.
The Main Menu window contains the following areas:
 A title line the top line of the Main Menu. This line displays the Setup
utility name and copyright message.
 The menu bar the line under the Setup title line. The menu bar
contains six top-level menus to set system parameters.
 A Main Menu summary window the area on the left side of the screen.
This area provides a summary of Main Menu Setup parameters. Some
Main Menu parameters can be set from this window or they can be set
from submenus.
