Chapter 1 INTRODUCTION
1.1 ABOUT THIS GUIDE
This guide provides technical information about Compaq Deskpro Personal Computers that feature
the Intel Pentium 4 processor and the Intel 850 chipset. This document includes information
regarding system design, function, and features that can be use d by programmers, engineers,
technicians, and system administrators.
This guide and any applicable addendums 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 S O URCES
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 Corpo ration: 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 Deskpro units is as follows:
XXX/XNNN/NNX/N/NNNxxx
NIC/Modem: blank = none, n = NIC, m = modem
Graphics: blank = integrated, a = AIMM, v = nVIDIA
Removable storage: b = CD/CDRW, c = CD, d = DVD, r = CDRW, z = ZIP
Memory (in MB)
OS type (9 = Dual install Win95/98, 4 = Win NT 4.0, 6 = Dual install Win NT/2000)
Chipset type (e = 850)
Hard drive size (in GB)
Processor speed (in MHz)
Processor type: C = Celeron; P = Pentium
Form factor: D = Desktop, M = Minitower
Deskpro series: EX = EXS, WK = Workstation

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 thro ugh 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 sta ndard Intel naming co nventions 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.
