Install the Operating System
CAUTION: Do not add optional hardware or third-party 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. 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 or prevent its
proper installation.
NOTE: Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the
monitor to permit the required airflow.
The first time the computer is turned on, the operating system is automatically installed. This takes
approximately 10 minutes, depending on the operating system being installed. Carefully read and follow
the instructions that appear on the screen to complete the installation.
NOTE: If the computer shipped with more than one operating system language on the hard
drive, the installation process could take up to 60 minutes.
If the computer was not shipped with a Microsoft operating system, some portions of this documentation
do not apply. For complete operating system installation and configuring instructions, refer to the
operating system documentation. Additional information is available in online help.
Microsoft security updates are available on the Microsoft Web site.
Installing or Upgrading Device Drivers
When installing optional hardware devices after the operating system installation is complete, you must
also install the drivers for each of the devices.
If prompted for the i386 directory, replace the path specification with C:\i386, or use the Browse button
in the dialog box to locate the i386 folder. This action points the operating system to the appropriate
drivers.
Obtain the latest support software, including support software for the operating system from
http://www.hp.com/support. Select your country and language, select Download drivers and
software, enter the model number of the computer, and press Enter.
Transferring Files and Settings
Use the Microsoft Windows XP Professional/Home Files and Settings Transfer Wizard to move files and
settings from the old computer to the new one. Click Start > All Programs > Accessories > System

HP Backup and Recovery Manager
The HP Backup and Recovery Manager is an easy-to-use, versatile application that is pre-loaded on
each system and allows you to:
●
create Recovery Points to back up the entire system incrementally
●
back up the entire system in a single hard archive
●
back up individual files
Backups can be scheduled to occur automatically at designated intervals, or they can be initiated
manually. Recovery can be performed from the Recovery Partition on the hard drive or the Recovery
Disc Set. The Recovery Disc Set includes the Restore Plus! CD, the Microsoft Operating System, and
any Supplemental Software CDs.
NOTE: HP highly recommends that you create a Recovery Disc Set immediately before using
the computer and schedule regular automatic Recovery Point backups.
To create the Recovery Disc Set:
1.
Click Start > HP Backup and Recovery > HP Backup and Recovery Manager to open the
Backup and Recovery Wizard, then click Next.
2.
Select Create factory software recovery CDs or DVDs to recover the system.
3.
Follow the instructions in the wizard.
The HP Backup and Recovery Manager provides two basic recovery methods. The first, recovery of
files and folders, operates in Windows. The second, PC Recovery, requires a reboot to the Recovery
Partition or from the Recovery Disc Set. To reboot to the Recovery Partition, press F11 at startup when
you see the message “Press F11 for Emergency Recovery.”
NOTE: For more information on using HP Backup and Recovery Manager, refer to the HP
Backup and Recovery Manager User Guide by selecting Start > HP Backup and Recovery >

In addition to allowing you to create the Restore Plus! CD set, HP Backup and Recovery Manager can
be used to back up data and system files to the hard drive, to network drives, or to removable media,
such as CDs, DVDs, or flash media. If data or system files are lost, deleted, or corrupted, Backup and
Recovery Manager allows you to retrieve data or restore the last good system image.
CAUTION: HP recommends that a backup schedule be created immediately to ensure
continued system and data protection. Automatic backups can be scheduled using the HP
Backup and Recovery Manager Wizard. Recovery Points, Entire Drive Backups, and File
Backups can be automatically backed up without user intervention. HP recommends scheduling
Recovery Point Backups to provide the most comprehensive coverage.
NOTE: If HP Backup and Recovery Manager is preinstalled, the Restore Plus! CD set and the
initial recovery point may be saved to disc as often as necessary, but only a single copy of the
Microsoft Windows CD can be created, due to licensing constraints.
You can access a user manual at Start > HP Backup and Recovery > HP Backup and
Recovery Manager Manual. We suggest that you print this document for easy reference in case
of future emergency.
If Create factory software recovery CDs or DVDs to recover the system is unavailable on
your system, the HP Restore Plus! CD set can be obtained through product support on

HP Client Management Interface
Regardless of the system management tools your IT department uses, managing both your hardware
and software assets is important to keeping your IT costs low and your business agile.
With the HP Client Management Interface (HP CMI), new HP business computers seamlessly integrate
into your managed IT environment. HP CMI provides an interface that simplifies the integration of HP
business computers with popular industry system management tools (including Microsoft Systems
Management Server, IBM Tivoli Software, and HP OpenView Operations) and custom inhouse
developed management applications. Using HP CMI, systems management tools and applications can
request in-depth client inventory, receive health status information, and manage system BIOS settings
by communicating directly with the client computer, reducing the need for agent or connector software
to achieve integration.
24
Chapter 4 Desktop Management
ENWW
NOTE: The system management tools mentioned above do not automatically connect into HP
CMI. Some script development is typically required to interface with HP CMI.
HP Client Management Interface is based on industry standards that include Microsoft Windows
Management Interface (MS WMI), Web-Based Enterprise Management (WBEM), System Management
BIOS (SMBIOS), and Advanced Configuration and Power Interface (ACPI). HP CMI is a foundation
technology utilized in HP Client Management Solutions. With HP CMI, HP gives you flexibility in choosing
how you manage your HP client computers.
HP Client Management Interface used in conjunction with system management software can:
●
Request in-depth client inventory information—Capture detailed information about the processors,
hard drives, memory, BIOS, drivers, including sensor information (such as fan speed, voltage, and
temperature)
●
Receive health status information—Subscribe for a wide range of client hardware alerts (such as
over-temperature, fan stall, and hardware configuration changes) to be sent to the system
management console, application, or to the local client computer. Alerts are sent real-time when
triggered by hardware events.
●
Manage system BIOS settings—Perform F10 functions including setting and changing the BIOS
passwords and computer boot order remotely from your system management console on any or
all of your client systems without having to visit each machine.
HP System Software Manager
HP System Software Manager (SSM) is a free utility that automates remote deployment of device drivers
and BIOS updates for your networked HP business PCs. When SSM runs, it silently (without user
interaction) determines the revision levels of drivers and BIOS installed on each networked client system
and compares this inventory against system software SoftPaqs that have been tested and stored in a
central file store. SSM then automatically updates any down-revision system software on the networked
PCs to the later levels available in the file store. Since SSM only allows distribution of SoftPaq updates
to the correct client system models, administrators can confidently and efficiently use SSM to keep
system software updated.
System Software Manager integrates with enterprise software distribution tools such as HP OpenView
Management Suite using Radia and Microsoft Systems Management Server (SMS). Using SSM, you
can distribute customer-created or third-party updates that have been packaged in the SSM-format.
SSM may be downloaded at no charge by visiting www.hp.com/go/ssm.
HP Client Manager
HP Client Manager, developed with Altiris, is available free for all supported HP business desktop,
notebook, and workstation models. SSM is integrated into HP Client Manager, and enables central
tracking, monitoring, and management of the hardware aspects of HP client systems.

ROM Flash
The computer's BIOS is stored in a programmable flash ROM (read only memory). By establishing a
setup password in the 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 the BIOS, you may download the latest BIOS images from the HP driver and
support page, http:///www.hp.com/support/files.
28
Chapter 4 Desktop Management
ENWW
CAUTION: For maximum ROM protection, be sure to establish a setup password. The setup
password prevents unauthorized ROM upgrades. System Software Manager allows the system
administrator to set the setup password on one or more PCs simultaneously. For more
information, visit http://www.hp.com/go/ssm.
Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the BIOS on remote HP
computers directly from the centralized network management console. Enabling the system
administrator to perform this task remotely on multiple computers results in a consistent deployment of,
and greater control over, HP PC BIOS images over the network. It also results in greater productivity
and lower total cost of ownership.
NOTE: The computer must be powered on, or turned on through Remote Wakeup, to take
advantage of Remote ROM Flash.
For more information on Remote ROM Flash, refer to the HP Client Manager Software or System
Software Manager at http://h18000.www1.hp.com/im/prodinfo.html.
HPQFlash
The HPQFlash utility is used to locally update or restore the system BIOS of individual PCs from a
Windows operating system.
For more information on HPQFlash, visit http://www.hp.com/support/files and enter the model number
of the computer when prompted.
Boot Block Emergency Recovery Mode
Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM flash
failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be
incomplete. This would render the system BIOS unusable. The Boot Block is a flash-protected section
of the ROM that contains code that checks for a valid system BIOS image when the system is turned
on.
●
If the system BIOS image is valid, the system starts normally.
●
If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to
●
search removable media for BIOS image files. If an appropriate BIOS image file is found, it is
automatically flashed into the ROM.
●
start the system from bootable removable media that automatically invokes system BIOS
upgrade utilities.
When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink
every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing
the video option ROM image is not corrupt, Boot Block Emergency Recovery Mode will be displayed
on the screen.
ENWW
Boot Block Emergency Recovery Mode
29
To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following
steps:
1.
Turn off the power.
2.
Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root
directory.
NOTE: The media must be formatted using the FAT12, FAT16, or FAT32 file system.
3.
Turn on the computer.
If no appropriate BIOS image file is found, the failsafe Boot Block BIOS will attempt to start the
system from a bootable device. If no bootable device is found, you will be prompted to insert media
containing a BIOS image file or BIOS upgrade utility.
If the system successfully reprograms the ROM, the system will automatically power off.
4.
Remove the removable media used to upgrade the BIOS.
5.
Turn the power on to restart the computer.
Replicating the Setup
The following procedures give an administrator the ability to easily copy one setup configuration to other
computers of the same model. This allows for faster, more consistent configuration of multiple
computers.
NOTE: Both procedures require a diskette drive or a supported USB flash media device, such
as an HP Drive Key.
Copying to Single Computer
CAUTION: A setup configuration is model-specific. File system corruption may result if source
and target computers are not the same model. For example, do not copy the setup configuration
from a dc7xxx PC to a dx7xxx PC.

Dual-State Power Button
With Advanced Configuration and Power Interface (ACPI) enabled, the power button can function either
as an on/off switch or as a standby button. The standby feature does not completely turn off power, but
instead causes the computer to enter a low-power standby state. This allows you to power down quickly
without closing applications and to return quickly to the same operational state without any data loss.
To change the power button’s configuration, complete the following steps:
1.
Left click on the Start Button, then select Control Panel > Power Options.
2.
In the Power Options Properties, select the Advanced tab.
3.
In the Power Button section, select Stand by.
After configuring the power button to function as a standby button, press the power button to put the
system in a very low power state (standby). Press the button again to quickly bring the system out of
standby to full power status. To completely turn off all power to the system, press and hold the power
button for four seconds.
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.
HP Web Site Support
HP engineers rigorously test and debug software developed by HP and third-party suppliers, and
develop operating system specific support software, to ensure performance, compatibility, and reliability
for HP computers.
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 the 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.

DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA
hard. DriveLock has been implemented as an extension to Computer Setup. It is only available when
hard drives that support the ATA Security command set are detected. DriveLock is intended for HP
customers for whom data security is the paramount concern. For such customers, the cost of the hard
drive and the loss of the data stored on it is inconsequential when compared with the damage that could
result from unauthorized access to its contents. In order to balance this level of security with the practical
need to accommodate a forgotten password, the HP implementation of DriveLock employs a twopassword security scheme. One password is intended to be set and used by a system administrator
while the other is typically set and used by the end-user. There is no "back-door" that can be used to
unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data
ENWW
Asset Tracking and Security
41
contained on the hard drive is replicated on a corporate information system or is regularly backed up.
In the event that both DriveLock passwords are lost, the hard drive is rendered unusable. For users who
do not fit the previously defined customer profile, this may be an unacceptable risk. For users who do
fit the customer profile, it may be a tolerable risk given the nature of the data stored on the hard drive.
Using DriveLock
When one or more hard drives that support the ATA Security command set are detected, the DriveLock
option appears under the Security menu in Computer Setup. The user is presented with options to set
the master password or to enable DriveLock. A user password must be provided in order to enable
DriveLock. Since the initial configuration of DriveLock is typically performed by a system administrator,
a master password should be set first. HP encourages system administrators to set a master password
whether they plan to enable DriveLock or keep it disabled. This will give the administrator the ability to
modify DriveLock settings if the drive is locked in the future. Once the master password is set, the system
administrator may enable DriveLock or choose to keep it disabled.
If a locked hard drive is present, POST will require a password to unlock the device. If a power-on
password is set and it matches the device’s user password, POST will not prompt the user to re-enter
the password. Otherwise, the user will be prompted to enter a DriveLock password. On a cold boot,
either the master or the user password may be used. On a warm boot, enter the same password used
to unlock the drive during the preceding cold-boot. Users will have two attempts to enter a correct
password. On a cold boot, if neither attempt succeeds, POST will continue but the drive will remain
inaccessible. On a warm boot or restart from Windows, if neither attempt succeeds, POST will halt and
the user will be instructed to cycle power.
DriveLock Applications
The most practical use of the DriveLock security feature is in a corporate environment. The system
administrator would be responsible for configuring the hard drive which would involve, among other
things, setting the DriveLock master password and a temporary user password. In the event that the
user forgets the user password or the equipment is passed on to another employee, the master
password can always be used to reset the user password and regain access to the hard drive.
HP recommends that corporate system administrators who choose to enable DriveLock also establish
a corporate policy for setting and maintaining master passwords. This should be done to prevent a
situation where an employee intentionally or unintentionally sets both DriveLock passwords before
leaving the company. In such a scenario, the hard drive would be rendered unusable and require
replacement. Likewise, by not setting a master password, system administrators may find themselves
locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset
control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users
in this category include personal users or users who do not maintain sensitive data on their hard drives
as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both
passwords is much greater than the value of the data DriveLock has been designed to protect. Access
to Computer Setup and DriveLock can be restricted through the Setup password. By specifying a Setup
password and not giving it to end users, system administrators are able to restrict users from enabling
DriveLock.

If the computer is connected to a network managed by HP Client Manager, the computer sends a fault
notice to the network management application. With HP Client Manager Software, you can also remotely
schedule diagnostics to automatically run on all managed PCs and create a summary report of failed
tests.
Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some HP
computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive
replacement.
When HP computers are built, each installed hard drive is tested using DPS, and a permanent record
of key information is written onto the drive. Each time DPS is run, test results are written to the hard
drive. You can use this information to help diagnose conditions that caused you to run the DPS software.
Refer to the Troubleshooting Guide on the Documentation and Diagnostics CD for instructions on using
DPS.

PATA Device Information
This model supports PATA drives.
ATA SMART Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be
properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the operating
system may differ from that marked on the hard drive or listed in the computer specification. Drive size
calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes
to the base 2.

Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
●
Different activities generate different amounts of static electricity.
●
Static electricity increases as humidity decreases.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.
●
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.
●
Never operate the computer with the cover or side panel removed.
●
Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.
●
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.
●
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software, including
sleep states.

Power Cord Set Requirements
The power supplies on some computers have external power switches. The voltage select switch feature
on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power
supplies on those computers that do not have external power switches are equipped with internal
switches that sense the incoming voltage and automatically switch to the proper voltage.
The power cord set received with the computer meets the requirements for use in the country where
you purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you use
the computer.
General Requirements
The requirements listed below are applicable to all countries:
1.
The power cord must be approved by an acceptable accredited agency responsible for evaluation
in the country where the power cord set will be installed.
2.
The power cord set must have a minimum current capacity of 10A (7A Japan only) and a nominal
voltage rating of 125 or 250 volts AC, as required by each country’s power system.
3.
The diameter of the wire must be a minimum of 0.75 mm2 or 18AWG, and the length of the cord
must be between 1.8 m (6 feet) and 3.6 m (12 feet).
The power cord should be routed so that it is not likely to be walked on or pinched by items placed upon
it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the
cord exits from the product.
WARNING! Do not operate this product with a damaged power cord set. If the power cord set
is damaged in any manner, replace it immediately.
Japanese Power Cord Requirements
For use in Japan, use only the power cord received with this product.
CAUTION: Do not use the power cord received with this product on any other products.

POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable
source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count
and non-error text messages. If a POST error occurs, the screen will display the error message. To
manually switch to the POST Messages Enabled mode during POST, press any key (except F10 or
F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory
test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see the Computer Setup (F10) Utility
Guide on the Documentation and Diagnostics CD.
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
●
All mass storage devices
●
Processors
●
Controllers
NOTE: 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.
If POST finds an error in the system, an audible and/or visual message occurs.

Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an additional
drive or expansion card. If you install a plug and play device, Windows XP automatically recognizes the
device and configures the computer. If you install a non–plug and play device, you must reconfigure the
computer after completing installation of the new hardware. In Windows XP, use the Add Hardware
Wizard and follow the instructions that appear on the screen.
WARNING! When the computer is plugged into an AC power source, voltage is always applied
to the system board. To reduce the risk of personal injury from electrical shock and/or hot
surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system
components to cool before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power
off the computer and remove the power cord before proceeding.
