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.

Enables/disables ability to boot the system from removable media.
eSATA Port
Allows you to set a SATA port as an eSATA port for use with an external drive.
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.
NOTE: eSATA is not available on USDT systems.
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.
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. Refer to the Advanced Host Controller Interface (AHCI) and
Redundant Array of Independent Disks (RAID) on HP Compaq dc7900 Business PCs white paper
at

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 19
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.

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.

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.

Grounding the Work Area
To prevent static damage at the work area, use the following precautions:
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected
●
to the work surface and properly grounded tools and equipment.
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
●
Handle them only at static-free work areas.
Turn off power and input signals before inserting and removing connectors or test equipment.
●
Use fixtures made of static-safe materials when fixtures must directly contact dissipative
●
surfaces.

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.
●
26 Chapter 4 Identifying the Chassis, Routine Care, and Disassembly Preparation
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.

Cable Management
Always 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 sliding or moveable parts to prevent them from being cut or crimped when
●
the parts are moved.
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 connectors 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).

Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) 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 MHz-
●
compliant
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.
Installing Additional Memory 39
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.
Figure 5-6 DIMM Socket Locations
Table 5-1 DIMM Socket Locations
Item Description Socket Color
1 XMM1 socket, Channel A (populate first) Black
2 XMM2 socket, Channel A (populate third) White
3 XMM3 socket, Channel B (populate second) White
4 XMM4 socket, Channel B (populate fourth) White
NOTE: A DIMM must occupy the black XMM1 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 1-GB DIMMs and Channel B is populated with one 2-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
40 Chapter 5 Removal and Replacement Procedures Convertible Minitower (CMT) Chassis
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB 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 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 31).
2. Remove the computer access panel (
3. Locate the memory module sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.

4. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 5-7 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.
Populate the DIMM sockets in the following order: XMM1, XMM3, XMM2, then XMM4.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B.
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 4 and 5 to install any additional modules.
7. Replace the computer access panel.
8. Reconnect the power cord and turn on the computer.
