Chapter 1 INTRODUCTION

1.1 ABOUT THIS GUIDE

This guide provides technical information about the Compaq iPAQ Family of Internet Devices. This document includes information regarding system design, function, and features that can be used by programmers, engineers, technicians, and system administrators.
This guide and any applicable addendum are available online at the following location:
http://www.compaq.com/support/techpubs/technical_reference_guides/index.html
1.1.1 USING THIS GUIDE
The chapters of this guide primarily describe the hardware and firmware elements and primarily deal with the system board and the power supply assembly. The appendices contain general information about standard peripheral devices such as the keyboard.
1.1.2 ADDITIONAL INFORMATION SOURCES
For more information on chipset components mentioned in this guide refer to the indicated manufacturers’ documentation, which may be available at the following online sources:
Compaq Computer Corporation: http://www.compaq.com
Intel Corporation: http://www.intel.com
Standard Microsystems Corporation: http://www.smsc.com

1.2 MODEL NUMBERING CONVENTION

The model numbering convention for Compaq iPAQ units is as follows:
iPAQ/XNNN/Nb/N/NNN
Memory (in MB) Operating system: 4 = Win NT 4.0; 9 = Win95/98 Chipset type (b = 810e) Hard drive size (in GB) Processor speed (in MHz) Processor type: C = Celeron; P = Pentium

First Edition - March 2000
Chapter 1 Introduction

1.3 NOTATIONAL CONVENTIONS

1.3.1 VALUES
Hexadecimal values are indicated by a numerical or alpha-numerical value followed by the letter h. Binary values are indicated by a value of ones and zeros followed by the letter “b. Numerical values that have no succeeding letter can be assumed to be decimal.
1.3.2 RANGES
Ranges or limits for a parameter are shown using the following methods:
Example A: Bits <7..4> = bits 7, 6, 5, and 4. Example B: IRQ3-7, 9 = IRQ signals 3 through 7, and IRQ signal 9
1.3.3 SIGNAL LABELS
Signal names are indicated using abbreviations, acronyms, or, if possible, the full signal name in all capital letters. Signals that are meant to be active (asserted) low are indicated with a dash immediately following the name.
1.3.4 REGISTER NOTATION AND USAGE
This guide uses standard Intel naming conventions in discussing the microprocessors (CPU) internal registers. Registers that are accessed through programmable I/O using an indexing scheme are indicated using the following format:
03C5.17h
Index port Data port
In the example above, register 03C5.17h is accessed by writing the index port value 17h to the index address (03C4h), followed by a write to or a read from port 03C5h.
1.3.5 BIT NOTATION
Bit values are labeled with bit <0> representing the least-significant bit (LSb) and bit <7> representing the most-significant bit (MSb) of a byte. Bytes, words, double words, and quad words are typically shown with most-significant portions on the left or top and the least­significant portions on the right or bottom respectively.

2.4 SYSTEM ARCHITECTURE

The Compaq iPAQ Internet Device features an Intel Celeron or Pentium III processor and the 810e chipset. As indicated in the following table and shown in Figure 2-6, four architectural configurations are available:
Legacy-free with Celeron processor
Legacy-free with Pentium III processor
Legacy-light with Celeron processor
Legacy-light with Pentium III processor
Legacy-free systems provide five Universal Serial Bus (USB) ports for connecting peripherals (including the supplied USB mouse and USB keyboard). Legacy light systems provide two USB ports along with the traditional PS/2 connectors for the supplied mouse and keyboard as well as parallel and serial port connectors.
All systems use the 810e chipset. The 810e chipset includes the 82810e-DC100 GMCH designed to provide control for SDRAM and also integrates an AGP 2X graphics controller. Pentium III­based systems come with an additional 4-MB display cache to compliment the graphics controller.
The 810e chipset also includes an 82801 I/O Controller Hub (ICH) that provides two IDE interfaces, two USB interfaces, and a PCI bus controller. The 82802 Firmware Hub (FWH) component is loaded with Compaq BIOS
