Preface
This publication provides information for the IBM IntelliStation E Pro. It is intended for developers who
want to provide hardware and software products to operate with this computer. It offers the details of how
the computer works. Users of this publication should have an understanding of computer architecture and
programming concepts.
Manual Style
In this manual, some signals are represented in a small, all-capital-letter format (-ACK). A minus sign in
front of the signal indicates that the signal is active low. No sign in front of the signal indicates that the
signal is active high.
The use of the term hex indicates a hexadecimal number. Also, when numerical modifiers such as “K”,
“M” and “G“ are used, they typically indicate powers of 2, not powers of 10. For example, 1 KB equals
1024 bytes (210), 1 MB equals 1048576 bytes (220), and 1 GB equals 1073741824 bytes (230).
When expressing storage capacity, MB equals 1000 KB (1024000). The value is determined by counting
the number of sectors and assuming that every two sectors equals 1 KB.
Note: Depending on the operating system and other system requirements, the storage capacity available
to the user might vary.
Attention! The term reserved describes certain signals, bits, and registers that should not be changed.
Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the
hardware. When the contents of a register are changed, the state of the reserved bits must be preserved.
When possible, read the register first and change only the bits that must be changed.

Chapter 1. System Overview
Software Features
The following features are supported by the IBM IntelliStation E Pro.
Wake on LAN
The power supply of the computer supports the Wake on LAN feature. With the Wake on LAN feature,
the computer can be turned on when a specific LAN frame is passed to the PC over the LAN.
To use the Wake on LAN feature, the computer must be equipped with a network subsystem that supports
Wake on LAN.
The menu used for setting the Wake on LAN feature is found in the Configuration/Setup Utility Program.
Wake Up on Ring
All models are configurable to turn on the computer after a ring is detected from an external or internal
modem. The menu used for setting the Wake Up on Ring feature is found in the Configuration/Setup
Utility Program. Two options control this feature:
Serial Ring Detect: Use this option if the computer has an external modem connected to the serial
port.
Modem Ring Detect: Use this option if the computer has an internal modem.
Alert on LAN
The IntelliStation E Pro features Alert on LAN, a product of the IBM/Intel Advanced Manageability Alliance.
Alert on LAN can notify you when a system has been tampered with or removed from the network. This
new feature is part of the IBM AssetCare, which also includes other innovations such as SMART Reaction
data protection software.
Asset ID
The Asset ID feature uses radio-frequency technology to read and write an EEPROM inside your
computer. The radio-frequency interface includes an Asset ID antenna inside the computer that enables
communications between industry-standard radio-frequency devices and your computer EEPROM. The
information in the EEPROM includes configuration data and serial numbers of key components. There are
also blank fields that can be recorded with the users choice of information. This information can be used
to track the movement of the computer for inventory and security purposes. The menu used for enabling
the Asset ID feature is found in the Configuration/Setup Utility Program. For more information about Asset
ID information, see “IBM AssetCare” on page 30 and “Asset ID” on page 35.

Euro Sign Support Information
The Euro Sign is the name given to the proposed currency symbol of the European Union. According to
the European Commission, the Euro will exist as a currency beginning 1 January 1999, but will only
gradually move into general use with the introduction of coins and notes in 2002.
IBM and various other personal computer industry companies plan to support the Euro Sign on products
released in 1999. For support information on products released prior to that date, see the appropriate
Web site for your product.
For your computer to support the Euro Sign, a proper combination of both hardware (computer, keyboard,
and printer) and software (operating systems, application programs, and device drivers) is required.
There are many Web sites that provide Euro Sign information and support (some are listed below). First,
determine the computer hardware and software you are using. Then, visit the Web sites that apply to your
system for the latest Euro Sign information and support. In many cases, updates are available for Euro
Sign support. These updates can be downloaded and installed on your computer.

bus. The chip set is capable of supporting PIO mode 0–4 devices and IDE DMA mode 0–2 devices, ultra
DMA 33 transfers up to 33 Mbytes/sec.
The IDE devices receive their power through a four-position power cable containing +5 V dc, +12 V dc,
and ground. When adding devices to the IDE interface, one device is designated as the master device
and another is designated as the slave or subordinate device. These designations are determined by
switches or jumpers on each device. There are two IDE ports, one designated 'Primary' and the other
'Secondary,' allowing for up to four devices to be attached. The total number of physical IDE devices is
dependent on the mechanical package.
For the IDE interface, no resource assignments are given in the system memory or the direct memory
access (DMA) channels. For information on the resource assignments, see “Input/Output Address Map”
on page 61 and Figure 49 on page 65 (for IRQ assignments).
Two connectors are provided on the riser for the IDE interface. For information on the connector pin
assignments, see “IDE Connectors” on page 55.
PCI-to-ISA Bridge
On the system board, the Intel PIIX4E provides the interface between the peripheral component interface
(PCI) and industry standard architecture (ISA) buses. The chip set is used to convert PCI bus cycles to
ISA bus cycles; the chip set also includes all the subsystems of the ISA bus, including two cascaded
interrupt controllers, two DMA controllers with four 8-bit and three 16-bit channels, three counters
equivalent to a programmable interval timer, and power management. The PCI bus operates at 33 MHz.
The ISA bus operates at 8.25 MHz.
For the ISA bus, no resource assignments are given in the system memory or the DMA channels. For
information on resource assignments, see “Input/Output Address Map” on page 61 and Figure 49 on
page 65 (for IRQ assignments).
USB Interface
Universal serial bus (USB) technology is a standard feature of the computer. Using the chip set, the
system board provides the USB interface with two connectors. A USB-enabled device can attach to each
connector, and if that device is a hub, multiple peripherals can attach to the hub and be used by the
system. The USB connectors use Plug and Play technology for installed devices. The speed of the USB
is up to 12 MB/sec with a maximum of 127 peripherals. The USB is compliant with Universal Host
Controller Interface Guide 1.0.
Features provided by USB technology include:
Support for hot pluggable devices
