3.3.1 HP System Software Manager
HP System Software Manager (SSM) is a free utility that automates remote deployment of
device drivers and BIOS updates for 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.
Desktop Management
System Software Manager integrates with enterprise software distribution tools such as
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
3.3.2 HP Client Manager
HP Client Manager, developed with Altiris, is available free for 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.
Use HP Client Manager to:
■ Get valuable hardware information such as CPU, memory, video, and security settings
■ Monitor system health to fix problems before they occur
■ Install drivers and BIOS updates without visiting each PC
■ Remotely configure BIOS and security settings
■ Automate processes to quickly resolve hardware problems
HP Client Manager uses the same Altiris infrastructure as the other Altiris client lifecycle
management solutions. This design provides a significant benefit for the IT staff, since only one
infrastructure needs to be setup and maintained. Since information is stored in one database, you
get complete and consistent inventory reports as well as system health and security information.
You use a single, consistent console interface for scheduling and tracking progress of both
hardware and software management tasks for client systems.

3.3.8 Retired Solutions
The Desktop Management Task Force (DMTF) introduced the Desktop Management Interface
(DMI) standard almost ten years ago. Due to new standards adoption such as the Common
Information Model (CIM), the DMTF has initiated end-of-life for DMI. Given other
advancements in HP Client Management Solutions, HP Systems Insight Manager, and
Microsoft's implementation of CIM, known as Windows Management Instrumentation (WMI),
the HP Insight Management Agent is no longer being provided on new HP commercial desktop,
workstation, and notebook models introduced after January 1, 2004.
The Insight Management (IM) Agent provided the following features:
■ DMI support allowed a client system to be managed by Insight Manager 7 or other
DMI-compliant management applications.
■ A Web agent allowed the system to be managed both locally and remotely by a web browser.
■ Health alerting could notify the user locally or be sent to a central console.
Insight Manager has been replaced by HP Systems Insight Manager Software (HP SIM). HP SIM
uses WMI to retrieve client system information. The Altiris Connector for HP Systems Insight
Manager is available and enables the HP Client Management Solutions through the HP SIM
console.
HP Client Management Solutions support reporting of health alerts to a system management
console or optionally to be displayed locally on the client computer. Microsoft WMI is standard
with Windows 2000 and Windows XP. WMI provides hardware inventory and alert information
directly through the Windows OS to a system management application.

3.4 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:
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.
3.4.1 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 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.

3.4.3 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.
Service Reference Guide, dx7200 390812-001 3–7
Desktop Management
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.
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.

3.5.4 DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data
on ATA hard drives. 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 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.
www.hp.com.
3–20 390812-001 Service Reference Guide, dx7200
Desktop Management
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. The
system administrator would be responsible for configuring the 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.

4.5 PATA Drive Installation Guidelines
The computer system boards for these products have one Parallel ATA (PATA) channel with a
single connector. The channel can have up to two devices attached to it. All drives are connected
to the 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 two drives.
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.
4.5.1 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.

4.6 SATA SMART Drives
The Self Monitoring Analysis and Recording Technology (SMART) SATA 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.
4.7 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.

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.

5.3 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.
