Option Description

Device Configuration Lists all installed BIOS-controlled storage devices.

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.

CD-ROM: Model, firmware version, serial number, connector color (not included for USB CD-

●

ROM).

SATA Defaults

Computer Setup (F10) Utilities 11

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.

www.hp.com.

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.

NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating

system has started.

Shortcut to Temporarily Override Boot Order

To boot one time from a device other than the default device specified in Boot Order, restart the
computer and press Esc (to access the boot menu) and then F9 (Boot Order), or only F9 (skipping

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.

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.

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.

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.

●

Operating Guidelines 27

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.

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: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard

drives only.

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.

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.

30 Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation

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

●

fields such as monitors or speakers.

Electrostatic Discharge Information on page 25

Lithium Coin Cell Battery

The battery that comes with the computer provides power to the real-time clock and has a minimum
lifetime of about three years.

See the appropriate removal and replacement chapter for the chassis you are working on in this
guide for instructions on the replacement procedures.

WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the

battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose
in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the
battery.

NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the

general household waste. In order to forward them to recycling or proper disposal, please use the
public collection system or return them to HP, their authorized partners, or their agents.

4-GB, PC3-12800 671613-001

2-GB, PC3-12800 671612-001

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3­SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to two industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a high­performing dual channel mode.

DDR3-SDRAM DIMMs

For proper system operation, the DDR3-SDRAM DIMMs must be:

industry-standard 240-pin

●

unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant

●

1.5 volt DDR3-SDRAM DIMMs

●

The DDR3-SDRAM DIMMs must also:

support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)

●

contain the mandatory JEDEC SPD information

●

In addition, the computer supports:

512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies

●

single-sided and double-sided DIMMs

●

DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not

●

supported

NOTE: The system will not operate properly if you install unsupported DIMMs.

54 Chapter 7 Removal and Replacement Procedures Small Form Factor (SFF) Chassis

Populating DIMM Sockets

There are two DIMM sockets on the system board: XMM1 and XMM3 with one socket per Channel.
XMM3 operates in memory channel A. XMM1 operates in memory Channel B.

The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.

The system will operate in single channel mode if the DIMM sockets are populated in one

●

channel only.

The system will operate in a higher-performing dual channel mode if the total memory capacity

●

of the DIMM in Channel A is equal to the total memory capacity of the DIMM in Channel B.

The system will operate in flex mode if the total memory capacity of the DIMM in Channel A is

●

not equal to the total memory capacity of the DIMM in Channel B. In flex mode, the channel
populated with the least amount of memory describes the total amount of memory assigned to
dual channel and the remainder is assigned to single channel. If one channel will have more
memory than the other, the larger amount should be assigned to Channel A.

● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

Installing DIMMs

CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power

to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.

The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.

Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

1. Prepare the computer for disassembly (Preparation for Disassembly on page 48).

2. Remove the access panel (

Computer Access Panel on page 50).

Installing Additional Memory 55

3. Rotate up the drive bay housing to access the memory module sockets on the system board.

Figure 7-6 Rotating the Drive Cage Up

4. Open both latches of the memory module socket (1), and insert the memory module into the

socket (2).

Figure 7-7 Installing a DIMM

NOTE: A memory module can be installed in only one way. Match the notch on the module

with the tab on the memory socket.

A DIMM must occupy the black XMM1 socket.

For maximum performance, populate the sockets so that the memory capacity is equal between
Channel A and Channel B. Refer to

Populating DIMM Sockets on page 55 for more information.

5. Push the module down into the socket, ensuring that the module is fully inserted and properly

seated. Make sure the latches are in the closed position (3).

Cable Management

The Small Form Factor 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 heat sink.

●

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 connector 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 (1).

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

CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could

damage the cable and result in a failed power supply.
