ACPI/USB Buffers @ Top of Memory (enable/disable).
Enabling this feature places USB memory buffers at the top of
memory. The advantage of remapping is that it allows space in
the DOS Compatibility Hole range, below 1MB, to be made
available for additional PCI plug-in cards that need option
ROM space. The disadvantage is that a popular memory
manager, HIMEM.SYS, does not work properly when USB
buffers are at top of memory AND the system has 64 KB or less

3.3.9 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 R OM upgrad e. The Boot Block is a
flash-protected section of the ROM that checks for a valid system ROM flash when po wer to the
system is turned on.

3–4 336492-003 Service Reference Guide, d500

Desktop Management

■ 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.

When the bootblock detects an invalid system ROM, The System Power LED blinks RED 8
times, one every second, followed b y 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, 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 a setup password has been established, the Caps Lock light will turn on and you will be
prompted to enter the password.

6. Enter the setup password.

7. 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.

8. Remove the diskette and turn the power off.

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

The following table lists the various keyboard light combinations used by the Boot Block ROM

3.4.4 DriveLock

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 dri ves 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

Service Reference Guide, d500 336492-003 3–13

Desktop Management

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 Driv eLock.
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.

3.5 Fault Notification and Recovery

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

When a fault occurs, the computer displays a Local Alert message containing a description of the
fault and any recommended actions. You can then view current system health by using the HP
Client Manager Software. If the computer is connected to a network managed by HP Insight
Manager, HP Client Manager Software, or other system management applications, the computer
also sends a fault notice to the network management application.

3.5.1 Drive Protection System

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 Tr ou bleshooting Guide for instructions on using
DPS.

4.3 PATA Drive Installation Guidelines

Most computer system boards have two ATA (IDE) channels with a dedicated connector for each
channel. One channel 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. Each computer system may
therefore have a maximum of four ATA/ATAPI drives. All dri ves are connected to these channels
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.

Service Reference Guide, d500 336492-003 4–3

Serial and Parallel ATA Drive Guidelines and Features

Any drive attached to a channel must hav e a dri v e designation. If only a single dri ve is connected
to a channel and its jumper is in the cable-select position, it is designated as the primary drive
(Drive/Device 0) by its attachment to the Drive/Device 0 cable position. If two cable-selected
drives are connected to a single channel, one will be designated by its attachment to the cable as
the primary (Drive/Device 0) and the other as secondary (Drive/Device 1).

For optimal performance of a computer system, all drives need to be attached to the ATA channel
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 1

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.

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.

Cable lengths may restrict drive usage.

✎

The rules allow for:

■ Keeping the hard drive on a separate channel to maximize drive performance until a fourth

device is added.

■ Keeping the hard drives and removable media drives on separate channels to maximize

compatibility.

■ Keeping the hard drive and the writable optical drive on separate channels to maximize

optical drive reliability.

4.3.4 PATA Additional Drive Application Notes

■ When replacing a hard drive, the replacement should be of the same type (Ultra ATA -33,

-66, or -100) as that being removed to retain the same level of performance.

■ 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.

4.4 PATA 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.

4.5 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.

5.2 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.

5.2.1 Generating Static

The following table shows that:

■ Different activities generate different amounts of static electricity.

■ Static electricity increases as humidity decreases.

5.2.2 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 re moving them from their container.

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

■ Avoid contact with pins, leads, or circuitry.
