Installing the Operating System
Depending on the model, Microsoft Windows XP Home or Windows XP Professional is
preinstalled on the computer and will be configured automatically the first time the computer is
turned on.
Ä
CAUTION: Do not add optional hardware devices to your computer until the operating system is
successfully installed. Doing so may cause errors and may prevent the operating system from installing
properly.
Ä
CAUTION: Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER UNTIL
THE PROCESS IS COMPLETE. Turning off the computer during the installation process might damage the
software that runs the computer.
1.1 Microsoft Windows XP
The first time the computer is turned on, Microsoft Windows is automatically installed. This
takes approximately 10 minutes, depending on the system hardware configuration. Read and
follow the instructions that appear on the screen to complete the installation.
During this process,
do not turn off your computer unless you are directed to do so.
1.1.1 Installing or Upgrading Device Drivers
To install optional hardware devices after the OS installation is completed, you must install the
device drivers for the device you are installing.
The I386 directory and its subdirectories provide the HP- or Compaq-specific integration of the
operating system for the computer model and include device drivers supported by the operating
system.
When prompted for the I386 directory on the operating system CD, replace the path specification
with C:\I386 or use the Browse button of the dialog box to browse the computer for the I386
folder. This action points to the appropriate drivers.
The latest support software is also available from the Web site at
http://www.hp.com/support.

Setup Utilities and Diagnostics Features
Setup Utilities (F10) and diagnostic features provide information needed about the computer
system when contacting Customer Support. These tools can also be used to:
■ Change factory default settings and to set or change the system configuration, which may be
necessary when you add or remove hardware.
■ Determine if all of the devices installed on the computer are recognized by the system and
functioning properly.
■ Determine information about the operating environment of the computer.
■ Solve system configuration errors detected but not automatically fixed during the Power-On
Self-Test (POST).
■ Establish and manage passwords and other security features.
■ Establish and manage energy-saving timeouts.
✎
All features identified in this chapter may not be available on all HP products.
2.1 Power-On Self-Test (POST)
POST is a series of diagnostic tests that runs automatically when the system is turned on. POST
checks the following items to ensure that the computer system is functioning properly:
■ Keyboard
■ Memory modules
■ Diskette drives
■ All IDE and SCSI mass storage devices
■ Processors
■ Controllers
✎
If the Power-On Password is set, a key icon appears on the screen while POST is running. You
will need to enter the password before continuing. Refer to Chapter 3,
Section 3.1, “Initial
Configuration and Deplo yment, ” for information on setting, deleting, or bypassing the password.
If POST finds an error in the system, an audible and/or visual message occurs. For POST error
messages and their solutions refer to Appendix C, “POST Error Messages.”

Desktop Management
HP Intelligent Manageability provides standards-based solutions for managing and controlling
desktops, workstations, and notebook PCs in a networked environment.
The capabilities and features of the seven key components of desktop management are:
■ Initial configuration and deployment
■ ROM flash
■ Security
✎
Support for specific features described in this guide may vary by model or software version.
3.1 Initial Configuration and Deployment
HP computers come with a preinstalled system software image. After a brief software
“unbundling” process, the computer is ready to be used.
A customized software image may be deployed by:
■ Installing additional software applications after unbundling the preinstalled software image.
■ Usin g software deployment tools, such as Altiris Deployment Solutions, to replace the
preinstalled software with a customized software image.
■ Using a disk cloning process to copy the contents from one hard drive to another.
The best deployment method depends on your information technology environment and
processes. The PC Deployment section of the Solutions and Services Web site
http://
h18000.www1.hp.com/solutions/pcsolutions
provides information to help you select the best
deployment method.
The Restore Plus! CD, ROM-based setup, and ACPI hardware provide further assistance with
recovery of system software, configuration management and troubleshooting, and power
management.
3.2 ROM Flash
The computer comes with a reprogrammable flash ROM (read only memory). By establishing a
setup password in Computer Setup (F10) Utility, you can protect the ROM from being
unintentionally updated or overwritten. This is important to ensure the operating integrity of the
computer. Should you need or want to upgrade your ROM, you may:
■ Order an upgraded ROMPaq™ diskette from HP.
■ Download the latest ROMPaq images from http://www.hp.com/support.
3–2 359782-002 Service Reference Guide, dx2000 uT
Desktop Management
3.2.1 FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash
failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is
a flash-protected section of the ROM that checks for a valid system ROM flash when power to
the system is turned on.
■ If the system ROM is valid, the system starts normally.
■ If the system ROM fails the validation check, the FailSafe Boot Block ROM provides
enough support to start the system from a ROMPaq diskette, which will program the system
ROM with a valid image.
To recover the system after it enters Boot Block recovery mode, complete the following steps:
1. If there is a diskette in the diskette drive, remove the diskette and turn off the power.
2. Insert a ROMPaq diskette into the diskette drive.
3. Turn on power to the system.
4. If no ROMPaq diskette is found, you will be prompted to insert one and restart the computer.
5. If the system successfully starts from the diskette and successfully reprograms the ROM,
then the three keyboard lights will turn on.
6. Remove the diskette and turn the power off.
7. Turn the power on again to restart the computer.
3.2.2 Dual-State Power Button
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, the power
button can function either as an on/off switch or as a suspend button. The suspend feature does
not completely turn off power, but instead causes the computer to enter a low-power standby.
This allows you to quickly power down without closing applications and to quickly return to the
same operational state without any data loss.
To change the power button’ s co nfiguration, complete the following steps:
1. Left click on the Start Button, then select Control Panel > Performance and
Maintenance > Power Options.
2. In the Power Options Properties, select the Advanced tab.
3. In the Power Button section, select the desired power button setting.
After configuring the power button to function as a suspend b utton, press the power button to put
the system in a very low power state (suspend). Press the button again to quickly bring the
system out of suspend to full power status. To completely turn off all power to the system, press
and hold the power button for four seconds.
Ä
CAUTION: Do not use the power button to turn off the computer unless the system is not responding;
turning off the power without operating system interaction could cause damage to or loss of data on the
hard drive.

3. Select the desired power scheme settings.
Use Display Properties to establish, modify, or disable Power Management settings for the
monitor. To access Display Properties, right click on the Windows Desktop, then choose
Properties.
3.2.4 World Wide Web Site
When making the transition to new or revised operating systems, it is important to implement the
support software designed for that operating system. If you plan to run a version of Microsoft
Windows that is different from the version included with your computer, you must install
corresponding device drivers and utilities to ensure that all features are supported and
functioning properly.
HP has made the task of locating, accessing, evaluating, and installing the latest support software
easier. You can download the software from
http://www.hp.com/support. The Web site contains
the latest device drivers, utilities, and flashable ROM images needed to run the latest Microsoft
Windows operating system on your HP computer.

Ultra ATA Drive Guidelines and Features
4.1 Ultra ATA Jumpers
Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with
the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on
factory pre installed, replacement, or option drives. With cable-select, the drive is configured as
either Master (Drive/De vice 0) or Slave (Driv e/Device 1) by its physical attachment to the cable.
If you purchase a third-party hard drive, refer to the documentation included with the drive kit to
ensure proper cable installation and configuration.
✎
All drives on a controller channel need to have their jumpers either in the cable-select mode or
have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave
(Drive/Device 1) position.
4.2 Ultra ATA Cables
When installing a second device on either the primary or secondary controller, you must use an
industry standard 40-pin, 80-conductor Ultra ATA cable for optimal performance. These cables
have a maximum length of 18 inches and a maximum distance of 6 inches between the two
devices for a two-drive cable.
Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-
standard 40-pin, 80-conductor cables to maintain the higher data transfer rates possible with the
improved technology.
When using Ultra ATA-133, -100, -66, and slower -33 dri ves in the same system, each drive will
operate at its appropriate data transfer rate.
4.2.1 Cable Layout
The faces of industry-standard cable connectors are color coded for easy recognition:
■ System board connector = blue face
■ Device 0 connecto r = black face
■ Device 1 connector = gray face
✎
The color code of an industry-standard cable is valid only if the drive’s jumper is in the cable-
select position.
4–2 359782-002 Service Reference Guide, dx2000 uT
Ultra ATA Drive Guidelines and Features
Single-Drive Cable
Two-Drive Cable
On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system
board connector and the Drive/Device 1 connector is always the closest to the system board
connector.
✎
Some cables may be labeled “Drive 0” instead of “Device 0” and “Drive 1” instead of
“Device 1”.
4.3 Drive Installation Guidelines
Most computer system boards have two ATA (IDE) controller channels with a dedicated
connector for each controller. One controller is designated as the primary and the other as the
secondary controller.
Each of the two controllers can have up to two devices attached to it. Each computer system may
therefore have a maximum of four ATA/ATAPI drives. All drives are connected to these
controllers using an industry-standard 40-pin, 80-conductor cable.
✎
The industry standard 1.44 MB diskette drive has its own separate channel and is not included as
a part of the maximum four drives.
Any drive attached to a controller must have a drive designation. If only a single drive is
connected to a controller and its jumper is in the cable-select position, it is designated as the
Master Drive (Drive/Device 0) by its attachment to the Drive/Device 0 cable position. If two
cable-selected drives are connected to a single controller, one will be designated by its
attachment to the cable as the Master (Drive/Device 0) and the other as Slave (Drive/Device 1).
For optimal performance of a computer system, all drives need to be attached to the ATA
controllers in a specified sequence. This sequence is determined by the device class of the drives
and by specific attach sequence rules.

Ultra ATA Drive Guidelines and Features
4.3.1 Device Classes
In order to determine the best drive attach sequence, ATA/ATAPI drives are segregated into four
different classes based upon the bandwidth demands they place on an ATA controller. The most
demanding devices are in Class 1 and the least demanding are in Class 4.
General Attach Guidelines
■ The lower the device class number, the faster the device and the more bandwidth required.
■ Drives installed in the Device 0 positions on both the primary and secondary controllers
receive the greatest possible bandwidth.
■ The bootable ATA hard drive should always be installed on the primary controller in the
Device 0 position.
4.3.2 Attach Sequence Rules by Class Priority
Drives should be attached in the sequence shown for optimum performance starting at
position 1.
*If there are three or more devices, two or more of which are hard driv es, tw o hard drives should
be attached to the primary controller first before following the General Attach Sequence Rule.

The attach sequence rule may also be stated in table format:
The rules allow for:
■ Keeping the hard drive on a separate controller channel maximizes drive performance until a
fourth device is added.
■ Keeping the hard drives and removable media drives on separate controller channels
maximizes compatibility.
■ Keeping the hard drive and the writable optical drive on separate controller channels
maximizes optical drive reliability.
4.3.3 Attach Sequence Worksheet
Use the worksheet below for obtaining optimum system performance when setting up a computer
with multiple drives. Use the General Attach Sequence Rule to determine the best drive
installation sequence.
Two examples of how to use the worksheet are:
■ Three device installation
■ Four device installation
General Attach Sequence Rule*
Sequence Description
1 The lowest class drive - bootable hard drive recommended.
2 If only two drives, the last drive goes here; otherwise the lowest class of the
remaining drives.
3 If only three drives, attach the final drive here. If a fourth drive exists, attach the
lowest class drive here.
4 If there is a fourth drive, attach the final drive here - the drive with the highest
class number of all devices.
*If there are three or more devices, two or more of which are hard drives, two hard drives
should be attached to the primary controller first before following the General Attach Sequence
Rule.
