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

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 microprocessor’s (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 least-
significant portions on the right or bottom respectively.
