2.4 Configuration Record

The Configuration Record utility is a windows-based information-gathering tool that gathers
critical hardware and software information from various computer subsystems. The information
includes such things as the ROM, asset tag, processor, physical drives, PCI devices, memory,
graphics, operating system version number, operating system parameters, and the operating
system startup files to give a complete view of the computer. Configuration Record provides a
means for automatically identifying and comparing configuration changes, and has the ability to
maintain a configuration history. The information can be saved as a history of multiple sessions.

This utility allows the resolution of problems without taking the computer offline and assists in
maximizing the computer availability. The information obtained by the utility is useful in
troubleshooting system problems, and streamlines the service process by enabling quick and easy
identification of system configurations.

The utility displays it findings in a Now.log file. If the original Base.log file is present in the
cpqdiags directory, the Base.log file is displayed next to the Now.log file in a split window with
the differences between the two highlighted in the color red.

The Configuration Record is part of Diagnostics for Windows and is automatically installed at
the same time as Diagnostics for Windows.

To run this program:

1. Click Start > HP Information Center > Configuration Record.

Alternately, you can access Diagnostics for Windows via the control panel.

The Configuration Record utility has two view options: Show Changed Items Only and Show
All. The default view is Show
color red since it shows only the differences. Switching to Show All displays the complete,
comprehensive view of the system.

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.

Using software deployment tools, such as Altiris Deployment Solution, 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

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.

Desktop Management

Remote System Installation allows you to start and set up your system using the software and
configuration information located on a network server by initiating the Preboot Execution
Environment (PXE). The Remote System Installation feature is usually used as a system setup
and configuration tool, and can be used for the following tasks:

Formatting a hard drive.

Deploying a software image on one or more new PCs.

Remotely updating the system BIOS in flash ROM. See Section 3.3.9, “Remote ROM
Flash.”

Configuring the system BIOS settings.

To initiate Remote System Installation, press when the F12 = Network Service Boot
message appears in the lower-right corner of the HP logo screen. Follow the instructions on the
screen to continue the process. The default boot order is a BIOS configuration setting that can be
changed to always attempt to PXE boot.

3.3.8 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 the HP driver and support page,

3.3.9 Remote ROM Flash

Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote HP
computers directly from the centralized network management console. Enabling the system
administrator to perform this task remotely, on multiple computers and personal computers,
results in a consistent deployment of and greater control over HP PC ROM images over the
network. It also results in greater productivity and lower total cost of ownership.

.

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 .

3.3.10 HPQFlash

The HPQFlash utility is used to locally update or restore the system ROM on individual PCs
through a Windows operating system.

For more information on HPQFlash, visit and enter the name
of the computer when prompted.

3.3.11 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.

Some models also support recovery from a ROMPaq CD. ISO ROMPaq images are included
with selected models in the downloadable ROM softpaqs.

When the boot block detects an invalid system ROM, the System Power LED blinks RED 8
times, one every second, followed by a 2-second pause. Also 8 simultaneous beeps will be heard.
A Boot Block recovery mode message is displayed on the screen (some models).

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 or a CD in the CD drive, remove the diskette and CD
and turn off the power.

2. Insert a ROMPaq diskette into the diskette drive or, if permitted on this computer, a ROMPaq
CD into the CD drive.

3. Turn on the computer.

If no ROMPaq diskette or ROMPaq CD is found, you will be prompted to insert one and
restart the computer.

If a setup password has been established, the Caps Lock light will turn on and you will be
prompted to enter the password.

4. Enter the setup password.

If the system successfully starts from the diskette and successfully reprograms the ROM,
then the three keyboard lights will turn on. A rising tone series of beeps also signals
successful completion.

5. Remove the diskette or CD and turn the power off.

6. Turn the power on again to restart the computer.

The following table lists the various keyboard light combinations used by the Boot Block ROM
(when a PS/2 keyboard is attached to the computer), and explains the meaning and action
associated with each combination.

DriveLock is an industry-standard security feature that prevents unauthorized access to the data
on specific hard drives. DriveLock has been implemented as an extension to Computer Setup. It
is only available on certain systems and only when DriveLock-capable hard drives 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 two-password 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 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

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. Either the master or the user password may be used. Users will have two attempts to
enter a correct password. If neither attempt succeeds, POST will continue but the drive will
remain inaccessible.

DriveLock Applications

The most practical use of the DriveLock security feature is in a corporate environment where a
system administrator provides users with multibay hard drives for use in some computers. The
system administrator would be responsible for configuring the multibay hard drive which would
involve, among other things, setting the DriveLock master 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.

Fault Notification and Recovery features combine innovative hardware and software technology
to prevent the loss of critical data and minimize unplanned downtime.

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.

The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in
select 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. Your service provider can use this information to help diagnose conditions that
caused you to run the DPS software. Refer to the Troubleshooting Guide for instructions on using
DPS.

An integrated surge-tolerant power supply provides greater reliability when the computer is hit
with an unpredictable power surge. This power supply is rated to withstand a power surge of up
to 2000 volts without incurring any system downtime or data loss.

The thermal sensor is a hardware and software feature that tracks the internal temperature of the
computer. This feature displays a warning message when the normal range is exceeded, which
gives you time to take action before internal components are damaged or data is lost.

PATA Drive Installation Guidelines

Most computer system boards have two or fewer Parallel ATA (PATA) channels with a dedicated
connector for each channel. When two channels are present, one is designated as the Primary and
the other as the Secondary Channel.

Each of the two channels can have up to two devices attached to it. All drives are connected to a
channel using an industry-standard 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.

HP does not support the use of PATA (IDE) hard drives when SATA hard drives are installed on
the computer.

Each drive attached to a channel must have a drive designation. If a drive is attached to the
Device 0 cable position and its cable-select jumper is present, the drive is designated as Device 0.
Similarly, if a drive is attached to the Device 1 cable position and its cable-select jumper is
present, the drive is designated as Device 1.

For optimal performance of a computer system, all drives need to be attached to the PATA
channel(s) in a specified sequence. This sequence is determined by the device class of the drives
and by specific attach sequence rules.

4.3.1 PATA 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 channel. The most
demanding devices are in Class 1 and the least demanding are in Class 4.

Class 3

Optical Storage

Drives

Class 4

Magnetic

Storage Drives

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 channels
receive the greatest possible bandwidth.

The bootable ATA hard drive should always be installed on the primary channel in the
Device 0 position.

4.3.2 PATA Attach Sequence Rules by Class Priority

Drives should be attached in the sequence shown for optimum performance starting at
position 1.

When Ultra ATA and SCSI hard drives are mixed in the same system, the Ultra ATA drive
will become the boot drive unless the boot order is changed in Computer (F10) Setup.

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.

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.

5.1.1 Slim Tower (ST)

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.

5.2.1 Generating Static

The following table shows that:

Different activities generate different amounts of static electricity.

Static electricity increases as humidity decreases.

Event 55% 40% 10%

Relative Humidity

700 volts can degrade a product.

5.2.2 Preventing Electrostatic Damage to Equipment

Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following packaging and grounding precautions are necessary to
prevent damage to electric components and accessories.

To avoid hand contact, transport products in static-safe containers such as tubes, bags, or
boxes.

Protect all electrostatic parts and assemblies with conductive or approved containers or
packaging.

Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.

Place items on a grounded surface before removing them from their container.

Always be properly grounded when touching a sensitive component or assembly.

Avoid contact with pins, leads, or circuitry.

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
conductive foam.

5.2.3 Personal Grounding Methods and Equipment

Use the following equipment to prevent static electricity damage to equipment:

Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the
ground cords. To provide proper ground, a strap must be worn snug against bare skin. The
ground cord must be connected and fit snugly into the banana plug connector on the
grounding mat or workstation.

Heel straps/Toe straps/Boot straps can be used at standing workstations and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats,
use them on both feet with a maximum of one-megohm ± 10% resistance between the
operator and ground.

To prevent static damage at the work area, use the following precautions:

Cover the work surface with approved static-dissipative material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.

Use static-dissipative mats, foot straps, or air ionizers to give added protection.

Handle electrostatic sensitive components, parts, and assemblies by the case or PCB
laminate. Handle them only at static-free work areas.

Turn off power and input signals before inserting and removing connectors or test
equipment.

Use fixtures made of static-safe materials when fixtures must directly contact dissipative
surfaces.

Keep work area free of nonconductive materials such as ordinary plastic assembly aids and
Styrofoam.

Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

Materials and equipment that are recommended for use in preventing static electricity include:

Antistatic tape

Antistatic smocks, aprons, or sleeve protectors

Conductive bins and other assembly or soldering aids

Conductive foam

Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance

Static-dissipative table or floor mats with hard tie to ground

Field service kits

Static awareness labels

Wrist straps and footwear straps providing one-megohm +/- 10% resistance

Material handling packages

Conductive plastic bags

Conductive plastic tubes

Conductive tote boxes

Opaque shielding bags

Transparent metallized shielding bags

Transparent shielding tubes

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.

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.

The computer is designed to operate continuously (24x7), provided that the operating
guidelines listed above are met.

Install or enable power management functions of the operating system or other software,
including sleep states.

1. Never use solvents or flammable solutions to clean the computer.

2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth

and then use the cloth on the component.

3. Always unplug the computer when cleaning with liquids or damp cloths.

4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.

5. Disconnect the keyboard before cleaning it.

6. Wear safety glasses equipped with side shields when cleaning the keyboard.

Follow all safety precautions in Section 5.4.1 before cleaning the computer.

To clean the computer case, follow the procedures described below:

To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it
with a cloth or swab dampened with clear water.

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will
evaporate quickly and not leave a residue.

After cleaning, always wipe the unit with a clean, lint-free cloth.

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the
vents and limit the airflow.

Cleaning the Keyboard

Follow all safety precautions in Section 5.4.1 before cleaning the keyboard.

5.4.2.

When cleaning debris from under the keys, review all rules in Section 5.4.1 before following
these procedures:

CAUTION:

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

Canned, pressurized air may be used to clean debris from under the keys. Caution should be
used as too much air pressure can dislodge lubricants applied under the wide keys.

If you remove a key, use a specially designed key puller to prevent damage to the keys. This
tool is available through many electronic supply outlets.

CAUTION:

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and
squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use
tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before
reassembly.

5.4.4 Cleaning the Monitor

Wipe the monitor screen with a clean cloth moistened with water or with a towelette
designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the
liquid may seep into the housing and damage a component. Never use solvents or flammable
liquids on the monitor.

To clean the monitor body follow the procedures in Section 5.4.2.

5.4.5 Cleaning the Mouse

Before cleaning the mouse, ensure that the power to the computer is turned off.

Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull
out any debris from the ball socket and wipe the ball with a clean, dry cloth before
reassembly.

To clean the mouse body, follow the procedures in Section 5.4.2.

The screws used in the computer are not interchangeable. They may have standard or metric
threads and may be of different lengths. If an incorrect screw is used during the reassembly
process, it can damage the unit. HP strongly recommends that all screws removed during
disassembly be kept with the part that was removed, then returned to their proper locations.

Metric screws have a black finish.
U.S. screws have a silver finish and are only used for hard drives.

As each subassembly is removed from the computer, it should be placed away from the work
area to prevent damage.

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with
care to avoid damage. Apply only the tension required to seat or unseat the cables during
insertion or removal from the connector. Handle cables by the connector whenever possible. In
all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way
that they cannot be caught or snagged by parts being removed or replaced.

Handle hard drives as delicate, precision components, avoiding all physical shock and vibration.
This applies to failed drives as well as replacement spares.

If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “Fragile: Handle With Care.”

Do not remove hard drives from the shipping package for storage. Keep hard drives in their
protective packaging until they are actually mounted in the CPU.

Avoid dropping drives from any height onto any surface.

If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard
drive while the computer is on or in standby mode.

Before handling a drive, ensure that you are discharged of static electricity. While handling a
drive, avoid touching the connector. For more information about preventing electrostatic
damage, refer to Section

Do not use excessive force when inserting a drive.

Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic
fields such as monitors or speakers.

6.5 Cable Management

The Slim Tower chassis is a very compact computer and proper routing of the internal cables is
critical to the operation of the computer. Follow good cable management practices when working
inside the computer.

Keep cables away from major heat sources like the heatsink.

Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like
these are not designed to take excessive pressure on them.

Keep cables clear of movable or rotating parts like the power supply and drive cage to
prevent them from being cut or crimped when the component is lowered into its normal
position.

When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.

Some flat ribbon cables come prefolded. Never change the folds on these cables.

Do not bend any cable sharply. A sharp bend can break the internal wires.

Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.

Never crease a SATA data cable.

Do not rely on components like the drive cage, power supply, or computer cover to push
cables down into the chassis. Always position the cables to lay properly by themselves.

When removing the power supply power cables from the P1 or P3 connectors on the system
board, always follow these steps:

1. Squeeze on the top of the retaining latch attached to the cable end of the connector .

2. Grasp the cable end of the connector and pull it straight up .
