When a device is selected, detailed information and options are displayed. The following options
may be presented:

Hard Disk: Size, model, firmware version, serial number, connector color.

●

Translation mode (ATA disks only)

Lets you select the translation mode to be used for the device. This enables the BIOS to
access disks partitioned and formatted on other systems and may be necessary for users of
older versions of UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift,
LBA Assisted, User, and Off.

Available only when the drive translation mode is set to User, allows you to specify the
parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate
disk I/O requests (from the operating system or an application) into terms the hard drive can
accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256.
The number of sectors per track may not exceed 63.

CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not

be changed. If the selected translation mode is not compatible with the translation mode that
was active when the disk was partitioned and formatted, the data on the disk will be
inaccessible.

SATA Defaults

10 Chapter 3 Computer Setup (F10) Utility

Table 3-3 Computer Setup—Storage (continued)

Storage Options eSATA Port

Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.

This setting affects only the port with the black connector, labeled as eSATA on the system board.
This port should have the eSATA back panel connector attached to use eSATA drives. For more
information, see the eSATA white paper at

SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are three supported options: IDE, RAID, and AHCI (default).

CAUTION: SATA emulation changes may prevent access to existing hard drive data and

degrade or corrupt established volumes.

IDE - This is the most backwards-compatible setting of the three options. Operating systems
usually do not require additional driver support in IDE mode.

RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driver
loaded in the operating system to take advantage of RAID features.

AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take
advantage of more advanced features of the SATA controller.

NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/

AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver
installed, the system will crash (blue screen). RAID volumes may become corrupted if they are
booted to after disabling RAID.

Removable Media Boot

Enables/disables ability to boot the system from removable media. Default is enabled.

Max eSATA Speed

Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed
is limited to 1.5 Gbps for maximum reliability.

CAUTION: Consult your eSATA drive and cable manufacturer before enabling 3.0 Gpbs speed.

Some drive and cable combinations may not run reliably at 3.0 Gpbs.

self-tests is attached to the system.

EFI Boot Sources: Specify the order in which EFI boot sources (such as a internal hard

●

drive, USB hard drive, USB optical drive, or internal optical drive) are checked for a bootable
operating system image. Each device on the list may be individually excluded from or
included for consideration as a bootable operating system source.

EFI boot sources always have precedence over legacy boot sources.

● Legacy Boot Sources: Specify the order in which legacy boot sources (such as a network

interface card, internal hard drive, USB optical drive, or internal optical drive) are checked for
a bootable operating system image. Each device on the list may be individually excluded
from or included for consideration as a bootable operating system source.

Specify the order of attached hard drives. The first hard drive in the order will have priority in
the boot sequence and will be recognized as drive C (if any devices are attached).

NOTE: To drag a device to a preferred place, press Enter. To remove the device from

consideration as a bootable device, press F5.

You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot.

Enables/disables Master Boot Record (MBR) security.

The MBR contains information needed to successfully boot from a disk and to access the data
stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes
to the MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities.
It also allows you to recover the "last known good" MBR, should changes to the MBR be detected
when the system is restarted.

When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the
current bootable disk while in MS-DOS or Windows Safe Mode.

NOTE: Most operating systems control access to the MBR of the current bootable disk; the

BIOS cannot prevent changes that may occur while the operating system is running.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.

Only appears if all of the following conditions are true:

MBR security is enabled

●

A backup copy of the MBR has been previously saved

●

● The current bootable disk is the same disk from which the backup copy was saved

CAUTION: Restoring a previously saved MBR after a disk utility or operating system has

modified the MBR, may cause the data on the disk to become inaccessible. Only restore a
previously saved MBR if you are confident that the current bootable disk's MBR has been
corrupted or infected with a virus.

● Measure boot variables/devices to PCR1 - Typically, the computer measures the boot path

and saves collected metrics to PCR5 (a register in the Embedded Security Device). Bitlocker
tracks changes to any of these metrics, and forces the user to re-authenticate if it detects
any changes. Enabling this feature lets you set Bitlocker to ignore detected changes to boot
path metrics, thereby avoiding re-authentication issues associated with USB keys inserted in
a port. Default is enabled.

OS management of Embedded Security Device (enable/disable) - This option allows the user to
limit OS control of the Embedded Security Device. Default is enabled. This option is automatically
disabled if Trusted Execution Technology is enabled.

● Reset of Embedded Security Device through OS (enable/disable) - This option allows the

user to limit the operating system ability to request a Reset to Factory Settings of the
Embedded Security Device. Default is disabled.

SATA Data Cable

Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA

1.5 Gb/s drives.

Current HP desktop products ship with SATA 3.0 Gb/s hard drives.

SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and
never bend it tighter than a 30 mm (1.18 in) radius.

The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

SATA Hard Drives 21

SMART ATA 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.

5 Routine Care, and Disassembly

Preparation

This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.

CAUTION: When the computer is plugged into an AC power source, voltage is always applied to

the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.

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

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.

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 removed.

●

Do not place computers so near each other that they are subject to each other’s re-circulated or

●

preheated air.

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.

●

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 General Cleaning Safety Precautions on page 26 before cleaning the
keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Computer Case on page 26.

When cleaning debris from under the keys, review all rules in

on page 26 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from

under the keys.

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: Never remove a wide leveled key (like the space bar) from the keyboard. If these

keys are improperly removed or installed, the keyboard may not function properly.

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed

Cleaning the Computer Case on page 26.

Screws

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.

CAUTION: As each subassembly is removed from the computer, it should be placed away from the

work area to prevent damage.

Cables and Connectors

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.

CAUTION: When servicing this computer, ensure that cables are placed in their proper location

during the reassembly process. Improper cable placement can damage the computer.

28 Chapter 5 Routine Care, and Disassembly Preparation

Hard Drives

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

● Do not use excessive force when inserting a drive.

● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic
