Chapter 1 INTRODUCTION

1.1 ABOUT THIS GUIDE

This guide provides technical information about Compaq D315 and the HP d325 personal

computers, both which feature the AMD Athlon XP processor and an NVidia NForce series

chipset. This document describes in detail the system’s design and operation for programmers,

engineers, technicians, and system administrators, as well as end-users wanting detailed

information.

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 data

such as error codes and information about standard peripheral devices such as keyboards, graphics

cards, and communications adapters.

This guide can be used either as an online document or in hardcopy form.

1.1.1 ONLINE VIEWING

Online viewing allows for quick navigating and convenient searching through the document. A

color monitor will also allow the user to view the color shading used to highlight differential data.

A softcopy of the latest edition of this guide is available for downloading in .pdf file format at the

URL listed below:

http://www3.compaq.com/support/home/selectproduct.asp?destination+reflib&pid+-1

Viewing the file requires a copy of Adobe Acrobat Reader available at no charge from Adobe

Systems, Inc. at the following URL:

http://www.adobe.com

When viewing with Adobe Acrobat Reader, click on the ( ) icon or "Bookmarks" tab to

display the navigation pane for quick access to particular places in the guide.

1.1.2 HARDCOPY

A hardcopy of this guide may be obtained by printing from the .pdf file. The document is

designed for printing in an 8 ½ x 11-inch format. Note that printing in black and white will lose

color shading used in some illustrations and tables.

1.4 SERIAL NUMBER

The unit’s serial number is located on a sticker placed on the exterior cabinet. The serial number

may also be read with the Compaq Diagnostics or Compaq Insight Manager utilities.

1.5 NOTATIONAL CONVENTIONS

The notational guidelines used in this guide are described in the following subsections.

Compaq D315 and hp d325 Personal Computers

Featuring the AMD Athlon XP Processor

Second Edition – April 2003

1-3

Chapter 1 Introduction

1.5.1 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 unless otherwise

stated.

1.5.2 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

1.5.3 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:
