1.3 System Design

This section presents a design overview and functional descriptions of the key components of the
Compaq Deskpro 2000 Series of Personal Computers. All replaceable components are identified in
Chapter 3, and removal/replacement instructions are presented in Chapter 5.

1.3.1 Design Overview

The desktop models of the Compaq Deskpro 2000 Series of Personal Computers have a conventional
design that uses a pan-type chassis to house the system board, expansion cards, power supply, and mass
storage devices. The chassis is supplemented by a riser board attached to the riser brace. The riser board
provides a mounting location for the expansion cards.

All internal components are accessible when the hood, held in place by two thumbscrews, is removed.
The front bezel is mounted to the front of the chassis. Torx T-15 screws are used throughout the system
except for the power supply switch mounting bracket, which uses T-10 screws.

The system board is easily removed from the side of the chassis after the hood and riser board are
removed. Two mounting screws secure the riser board to the riser brace. Four mounting screws are used
on the Pentium and five screws on the Pentium Pro to secure the system board to the chassis. In
addition, the I/O bracket is mounted to the system board and is spared that way.

The riser board mounts perpendicular to the system board. Expansion boards are installed horizontally
into the riser board. A single screw attaches each expansion board to the rear panel of the chassis.

The power supply is mounted in the right rear corner of the chassis. The power supply is held in place
by five Torx screws, two mounted internally and three that are installed through the rear panel of the
chassis.

The minitower models’ chassis is designed to house the system board, riser board, option cards, power
supply, and mass storage devices. The use of a riser brace to hold the riser board, and any expansion
boards installed, allows for easy access to the system board. The power supply is mounted in the top of
the unit.

All internal components are immediately accessible when the side panel, held in place with three
thumbscrews, is removed. The front bezel is a separate assembly that mounts to the front of the chassis.

The tray-mounted system board is easily removed by taking off the side panel, removing the riser brace,
and then pulling the tray assembly from the chassis. The system board is spared installed in the tray.

Detailed descriptions of the system components are presented in the sections that follow.

1-6 Product Description

1.3.2 System Board

The desktop and minitower models of the Compaq Deskpro 2000 Series of Personal Computers use two
basic system board configurations, either a Pentium- or a Pentium Pro–based board. The desktop units
have the I/O panel mounted to the system board and are spared with the I/O panel attached. On the
minitower, the system board is attached to a sliding tray and is spared with the tray.

1.3.3 Processor

The Pentium-based system boards run at processor speeds of 100MHz to 200MHz.
The Pentium Pro-based system boards run at processor speeds of 180MHz and 200MHz.

1.3.4 System Memory

The system supports base (conventional) and extended memory. Operating systems such as MS-DOS,
OS/2, UNIX, and all application programs use base memory. For better performance, Windows NT,
OS/2, and UNIX, as well as many MS-DOS applications, use extended memory.

The computers ship standard with 60-ns EDO tin-lead (SnPb) SIMMs installed and supports up to 128
megabytes of memory (Pentium models) or 192 megabytes of memory (Pentium Pro models). Either
Extended Data Out (EDO) random access memory (RAM) or Fast Page Mode (FPM) dynamic random
access memory (DRAM) modules may be used. If EDO and FPM modules are combined in the
computer, they must be as matched pairs. For example, two identical EDO modules may be used with
two identical FPM modules.

The SIMM sockets on all system boards in this series of computers can be populated with 4-, 8-, 16-, or
32-MB SIMMs in matched pairs. SIMM sockets on the system boards must be populated in pairs of
equal size in sequential slots. The SIMMs for the system boards must be 60 ns or 70 ns. Refer to
Chapter 5, “Removal and Replacement Procedures,” for information on how to upgrade system
memory.

The Pentium-based system boards accommodate a total of four SIMMs.
The Pentium Pro-based system boards accommodate a total of six SIMMs.

SIMMs with tin-lead pins must be used for memory upgrades.

✎

System memory speed will be configured on a bank-by-bank basis allowing each bank to run at its

✎

optimum speed.

1.3.5 Cache Memory

Cache memory is very fast memory used for temporarily storing data for fast access by the processor.
The faster the processor, the more need there is for temporary data storage. One 256-kilobyte write­back, direct mapped secondary (L2) cache module is installed on the Pentium system board. Cache is
standard on models with a speed of 120 megahertz or higher. Cache is optional on lower speed
processors. A 256-kilobyte write-back, four-way, set associative secondary (L2) cache is integrated into
the processor on Pentium Pro models.

Compaq Deskpro 2000 1-7

1.3.6 Graphics Controllers

The purpose of a graphics controller is to generate the text and graphics images for the monitor screen.
The quality of the picture you see depends on the resolution of the monitor and the number of colors
that can be displayed. High resolution graphics with many colors require that the graphics controller
have its own memory system. The computer comes with one of three graphics controllers:

■

The Cirrus Logic 5436 PCI performance graphics controller comes standard with 1 megabyte of
EDO DRAM, which can be upgraded to 2 megabytes of EDO DRAM.

■

The Cirrus Logic 5446 PCI performance graphics controller comes standard with 1 megabyte of
EDO DRAM, which can be upgraded to 2 megabytes of EDO DRAM.

■

The Matrox MGA Millennium graphics controller comes standard with 2 megabytes of Windows
random access memory (WRAM), which can be upgraded to 4 or 8 megabytes of WRAM.

Supported screen resolutions for each of the above controllers are listed in Chapter 8, "Specifications".

1.3.7 IDE Peripheral Interface

The onboard PCI chipset provides a high-speed, 32-bit PCI/IDE interface, which supports the
following:

■

Up to four PCI/IDE hard drives on the PCI bus

■

Enhanced Mode 3 and Mode 4 support

■

Logical block addressing (LBA) of hard drives larger than 528 megabytes

■

1-8 Product Description

1.3.9 System BIOS

The system BIOS provides ISA and PCI compatibility. Contained in a flash memory device on the
system board, the BIOS provides the power-on self-test (POST) and the PCI and IDE auto­configuration utilities.

The system BIOS is always “shadowed.” Shadowing allows any BIOS routines to be executed from fast
32-bit onboard DRAM instead of from the slower 8-bit flash device.

PCI Auto-Configuration

The PCI auto-configuration utility works in conjunction with the Setup program to support using PCI
expansion boards in the system. When you turn on the computer power after installing a PCI board, the
BIOS automatically configures interrupts, I/O space, and PCI devices. If problems arise or you wish to
reconfigure the device, refer to Chapter 7, “Compaq Utilities,” which explains how to use the Setup
program. The PCI auto-configuration program complies with version 2.1 of the PCI BIOS specification.

IDE Auto-Configuration

If you install an IDE drive into the computer, the IDE auto-configuration utility automatically detects
and configures the drive for operation in the computer. This utility eliminates the need to run the Setup
program after you install an IDE drive.

ISA Plug and Play Capability

ISA Plug and Play capability provides auto-configuration of Plug and Play ISA boards and resource
management for legacy (non Plug and Play) ISA boards when used with Compaq’s Computer Setup for

F10

Windows (CSW) utility (or
Windows 95.

Setup) or a Plug and Play–compatible operating system like Microsoft’s

BIOS Upgrades

Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS without having
to disassemble the system. The flash upgrade process can be accomplished by running a utility from a
diskette, a hard drive, or over a network.

The section on Flash ROM in Chapter 7, “Compaq Utilities,” explains how to run the BIOS upgrade
utility. For information about the latest BIOS update, contact an authorized Compaq service provider.

1.3.10 Expansion Slots

The computer has two dedicated 16-bit ISA-compatible slots, two dedicated PCI-compatible expansion
slots, and one “combination slot” that can be used by either a PCI or an ISA board. For more
information about expansion slots and installing expansion boards, see Chapter 5, “Removal and
Replacement Procedures.”

1.3.11 Power Supply

The desktop and the minitower computers share a 200-watt rated continuous power supply to provide
power for onboard resources, expansion boards, and drives. A switch on the computer back panel sets
the power supply to operate at:

■

115 VAC (in the range of 100-120 VAC; 5.0 A maximum input current)

■

230 VAC (in the range of 200-240 VAC; 3.0 A maximum input current)

For power supply output ratings, see Chapter 8, “Specifications.”

Compaq Deskpro 2000 1-9

1.3.12 Diskette Drive Interface

The diskette drive interface is 8477 compatible and supports two storage devices (diskette or tape
drive).

1.3.13 Serial Port

The serial port is RS-232C compatible.

1.3.14 Parallel Port

The following parallel support modes are supported:

■

SPP (Bidirectional Standard Parallel Port)

■

EPP (Enhanced Parallel Port)

■

ECP (Extended Capabilities Port)

1.3.15 System Security

The system BIOS provides a power-on password option that is enabled through the Setup program. The
computer includes a cable lock provision that makes it possible to lock the computer cover in place to
prevent unauthorized access to the system jumpers and other internal components (a padlock is not
included). For more information on this and additional security features, refer to Chapter 2,
“Troubleshooting,” and Chapter 7, “Compaq Utilities.”

1.3.16 Keyboard/Mouse Controller

The onboard 8042 I/O controller stores the keyboard and mouse controller code. Connectors for the
keyboard and mouse are located on the back panel.

1.3.17 Real-Time Clock and CMOS RAM

The onboard I/O controller provides a real-time clock and CMOS RAM. Chapter 5 provides
information about installing a new battery.

You can set the time for the clock and the CMOS values by using the Setup program described in
Chapter 7, “Compaq Utilities.”

1.3.18 Power Supply Fan

For cooling, a fan is attached to the power supply at the rear of the computer chassis. This fan draws air
in through the front of the chassis and exhausts air out the rear of the chassis. This provides air flow
across the processor.

1.3.19 Speaker

An internal piezo speaker is mounted on the system board. The speaker provides audible error code
information (beep codes) during the power-on self-test (POST) and as required by the software. See
Chapter 2, “Troubleshooting,” for beep code information.

2.4.1 SCSI Error Codes

The SCSI error codes are written in the format AABB-CC and can be determined by looking up the
respective parts of the code in the three corresponding tables numbered 2-16, 2-17, and 2-18. AA (Table
2-16) identifies the drive type being tested. BB (Table 2-17) identifies the type of test. CC (Table 2-18)
identifies the exact error received.

For example, if you received a diagnostic error code of 6523-05, you would look at Table 2-16 to
identify the meaning of the first two numbers, 65. This indicates a hard drive problem. The second set
of two numbers, 23, refers to a random read, as shown in Table 2-17. The last two numbers, 05, indicate
a seek failure, as listed in Table 2-18. When you combine this information, you know that the
diagnostics program was testing the random-read functioning of the hard drive and received a seek
failure. The device is faulty and must be replaced.

2.5.6 Hard Drive Problems

This section identifies some quick checks for hard drive–related problems.

The IntelliSafe hard drive stores prefailure information on certain parameters during drive

✎

operation. At some point, this information indicates that the drive should fail sometime in the
future, even though it is currently working properly. When you run diagnostics, if there is any
prefailure information stored on the drive, the computer will fail the hard drive diagnostics test.
Proof of this test failure is required when returning a hard drive to Compaq as a failed hard drive.

The information provided by the diagnostics test includes: error code, system serial number, drive serial
number, drive model, and drive firmware revision. Specific details of the drive failure are not included.

When you run the diagnostics, the test results are stored in a log. After completing the test, you can
print this log to a local printer or save it to a file. Alternatively, before running the test, you can
configure the test options to send the results to a local printer or file.

Solutions for some typical hard drive problems are presented in Table 2-23.

2.5.7 Hardware Installation Problems

This section identifies some quick checks for hardware problems.

Table 2-24

Solutions for Hardware Installation Problems

Problem Possible Solutions

A new device is not recognized as part of
the computer system.

The computer supports plug and play, but
the hardware configuration settings in
Computer Setup do not match the settings
in Windows 95 Device Manager.

1. The Computer Setup utility has not been run to configure the new device. Run the Computer
Setup utility.

2. When the system advised you of changes to the configuration, you did not accept them.
Reboot the computer and follow the instructions for accepting the changes.

3. The system may not have automatically recognized the new device. If Windows 3.1 is
installed, run Computer Setup and identify the new device. If Windows 95 is installed, run
Device Manager and identify the device.

4. A Plug and Play board may not automatically configure when added if the default
configuration conflicts with other devices. Use Computer Setup (Windows 3.1 installed) or
Device Manager (Windows 95 installed) to deselect the automatic settings for the board and
choose a basic configuration that doesn’t cause a resource conflict.

5. The cables for the new external device are loose or the power cables are unplugged. Check
all cables.

6. The power switch for the new external device is not turned on. Turn off the computer, turn on
the external device, and then turn the computer on to integrate the new device with the
computer.

7. If the drive is a secondary drive that has just been installed
on the same controller as the primary drive, verify that the jumpers for both drives are set
correctly.

In Windows 95, when onboard serial devices are assigned to ports other than COM1 or COM2,
the configuration is saved statically in CMOS. When the system is rebooted, the ROM
configures the device to the static setting; when Windows 95 loads, it configures the device to
the configuration set via Device Manager. In such cases, the configuration shown when F10
Setup is run does not match what was set up via Device Manager.

If these devices must be configured a certain way before Windows 95 loads, then the serial
port devices on the system should only be configured to COM1 or COM2 resources. If the
system has two serial devices plus a modem, then the first serial device can be COM1 or
COM2 or disabled, the modem can be COM1 or COM2 or disabled, and the second serial
device can be COM4 or disabled.

then run the Configuration utility. (If the system contains mixed EDO and FPM DRAMs, the
EDO pair is one bank and the FPM pair is another bank.)

1. Too many Terminate and Stay Resident programs (TSRs) are installed. Delete any
unnecessary TSRs.

2. The computer has run out of memory for the application. Check the memory
requirements for the application or add more memory to the computer.
