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:

Drive Emulation

Allows you to select a drive emulation type for a certain storage device. (For example, a Zip drive
can be made bootable by selecting diskette emulation.)

Emulation Type

ATAPI Zip drive:

●

None (treated as Other).

●

Diskette (treated as diskette drive).

CD-ROM: No emulation options available.

ATAPI LS-120:

●

None (treated as Other).

●

Diskette (treated as diskette drive).

Hard Disk:

●

None (prevents BIOS data accesses and disables it as a boot device).

●

Hard Disk (treated as hard disk).

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.

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.

Translation Parameters (ATA disks only)

NOTE: This feature appears only when User translation mode is selected.

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. These fields are only visible
and changeable when the drive translation mode is set to User.

10 Chapter 2 Computer Setup (F10) Utility

Option Description

Storage Options Removable Media Boot

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

eSATA Port

Allows you to enable eSATA support. This causes one of the SATA connectors to become eSATA
capable.

Max eSATA Speed

Allows you to choose 1.5 Gbps or 3.0 Gbps 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 Gbps speed.

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

SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are two supported options: IDE and AHCI.

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

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

NOTE: The AHCI device driver must be installed prior to attempting to boot from an AHCI

volume. If you attempt to boot from an AHCI volume without the required device driver installed,
the system will crash (blue screen).

For more information on AHCI, go to

http://www.hp.com/support. Select your country and

language, select See support and troubleshooting information, enter the model number of the
computer, and press Enter. In the Resources category, click Manuals (guides, supplements,

addendums, etc). Under Quick jump to manuals by category, click White papers.

System (DPS) self-tests.

NOTE: This selection will only appear when at least one drive capable of performing the DPS

self-tests is attached to the system.

Boot Order Allows you to:

●

Specify the order in which attached devices (such as a USB flash media device, hard drive,
optical drive, or network interface card) 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: 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 F9 when the monitor light turns green. After POST is completed, a list of
bootable devices is displayed. Use the arrow keys to select the preferred bootable device and
press Enter. The computer then boots from the selected non-default device for this one time.

the user will be prompted to correctly enter it before being allowed to enter the MEBx Setup.
It the password is entered incorrectly three times, the MEBx Setup will not be activated.

● SOL Character Echo (enable/disable). Some remote consoles print remotely-entered

characters which can cause the characters to appear twice (once when entered remotely
and once when echoed back from local client video). This option allows the administrator to
have the SOL terminal emulator suppress echoing remotely-entered characters to the local
video display.

●

SOL Terminal Emulation Mode (enable/disable). Selects between VT100 and ANSI SOL
terminal emulation. SOL terminal emulation mode is only activated during remote AMT
redirection operations. The emulation options allow administrators to select which mode
works best with their console.

● SOL Keyboard (enable/disable). Disable or enable client keyboard during SOL sessions.

Some remote remediation may involve having the local client boot a remote image provided
by an administrator. This option determines if the BIOS will keep the local keyboard enabled
or disabled for possible local client interaction. If the local keyboard is disabled, all keyboard
input is only accepted from the remote source.

Recovering the Configuration Settings

This method of recovery requires that you first perform the Save to Removable Media command
with the Computer Setup (F10) Utility before Restore is needed. (See

Save to Removable Media

on page 9 in the Computer Setup—File table.)

NOTE: It is recommended that you save any modified computer configuration settings to a a USB

flash media device or a diskette-like device (a storage device set to emulate a diskette drive) and
save the device for possible future use.

To restore the configuration, insert a USB flash media device or other storage media emulating a
diskette with the saved configuration and perform the Restore from Removable Media command

4 Identifying the Chassis, 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.

Chassis Designation

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.

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.

on page 28 before following these procedures:

WARNING! Use safety glasses equipped with side shields before attempting to clean debris from

under the keys.

CAUTION: Visible debris underneath or between the keys may be removed by vacuuming or

shaking.

CAUTION: 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.

CAUTION: 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.

28 Chapter 4 Identifying the Chassis, Routine Care, and Disassembly Preparation

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.

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.

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

Cleaning the Computer Case on page 28.

Cleaning the Mouse

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

Service Considerations 29

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

CAUTION: 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

Electrostatic Discharge Information on page 24

●

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.

Installing Additional Memory

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 four 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 16-GB of memory configured in a
high-performing dual channel mode.

DDR3-SDRAM DIMMs

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

●

industry-standard 240-pin

●

unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz­compliant

NOTE: 1333 MHz DIMMS will only run at a speed of 1066 MHz.

●

1.5 volt DDR3-SDRAM DIMMs

The DDR3-SDRAM DIMMs must also:

● support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz

(9-9-9 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.

36 Chapter 5 Removal and Replacement Procedures

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel A. Sockets DIMM3 and DIMM4 operate in memory channel B.

Figure 5-4 DIMM Socket Locations

Table 5-1 DIMM Socket Locations

Item Description Socket Color

1 DIMM1 socket, Channel A (populate first) Black

2 DIMM2 socket, Channel A (populate third) White

3 DIMM3 socket, Channel B (populate second) White

4 DIMM4 socket, Channel B (populate fourth) White

NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system will

display a POST error message indicating that a memory module must be installed in
the wrong socket.

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 DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is
populated with two 512-MB DIMMs and Channel B is populated with one 1-GB DIMM, the
system will operate in dual channel mode.

●

The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is
not equal to the total memory capacity of the DIMMs 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. For optimal speed, the channels
should be balanced so that the largest amount of memory is spread between the two channels.
If one channel will have more memory than the other, the larger amount should be assigned to

Installing Additional Memory 37

Channel A. For example, if you are populating the sockets with one 1-GB DIMM, and three 512­MB DIMMs, Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and
Channel B should be populated with the two 512-MB DIMMs. With this configuration, 2-GB will
run as dual channel and 512-MB will run as single channel.

●

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. If you see an LED light on the system board, voltage is still
present.

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 32).

2. Remove the access panel (

Access Panel on page 32).

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

board.

socket (2).

Figure 5-6 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 DIMM1 socket.

Populate the DIMM sockets in the following order: DIMM1, DIMM3, DIMM2, then DIMM4.

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

Populating DIMM Sockets

on page 37 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).

6. Repeat steps 5 and 6 to install any additional modules.

The computer should automatically recognize the additional memory the next time you turn on the
computer.

Cable Management

The chassis is very compact 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 P1 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.
