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, serial number, connector color, SMART, translation mode.
Translation mode 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 None.
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; 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.
Default Values: Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and Translation Mode for ATA devices.
CD-ROM: Model, firmware, serial number, connector color. No emulation options available.
Storage Options Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enable.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating system. There are two supported options: AHCI and IDE.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of more advanced features of the SATA controller.
IDE - This is the most backwards-compatible setting of the two options. Operating systems usually do not require additional driver support in IDE mode.
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).

4 Serial ATA (SATA) Drive Guidelines
and Features
NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel
ATA (PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics
Number of pins/conductors in data cable 7/7
Number of pins in power cable 15
Maximum data cable length 39.37 in (100 cm)
Data interface voltage differential 400-700 mV
Drive voltages 3.3 V, 5 V, 12 V
Jumpers for configuring drive N/A
Data transfer rate 3.0 Gb/s

SATA Hard Drive Cables

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.
20 Chapter 4 Serial ATA (SATA) Drive Guidelines and Features

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.
Static electricity increases as humidity decreases.

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.

Cleaning the Computer Case on page 26.

Screws

Diagnostics software
HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper-
resistant bits (Smart Cover FailSafe Key, PN 166527-002)
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.
Service Considerations 27

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.
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.

A Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer Setup Utilities menu.
This computer supports two security password features that are established through the Computer Setup Utilities menu: setup password and power-on password. When you establish only a setup password, any user can access all the information on the computer except Computer Setup. When you establish only a power-on password, the power-on password is required to access Computer Setup and any other information on the computer. When you establish both passwords, only the setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to the information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup. See
Computer Setup (F10) Utility on page 9 for information.

Resetting a Setup or Power-on Password

To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete the following steps:
1. Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any
residual power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to
the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the access panel.
4. Locate the header and jumper labeled PSWD (the label may be under the memory module).
NOTE: The password jumper is blue so that it can be easily identified. For assistance locating
the password jumper and other system board components, see the Illustrated Parts & Service Map (IPSM). The IPSM can be downloaded from
5. Remove the jumper.
6. Replace the jumper.
7. Replace the access panel.

Clearing and Resetting the CMOS

The computer’s configuration memory (CMOS) stores information about the computer’s configuration.
The CMOS button resets CMOS but does not clear the power-on and setup passwords.
Clearing CMOS will clear the Active Management Technology (AMT) settings in the Management Engine BIOS Extension (MEBx), including the password. The password will default to “admin” and will need to be reset. The AMT settings will also need to be reset. To access the MEBx, press Ctrl+P during POST.
1. Turn off the computer and any external devices, and disconnect the power cord from the power
outlet.
2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.

B POST Error Messages

This appendix lists the error codes, error messages, and the various indicator light and audible sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and non-error text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST Messages Enabled mode during POST, press any key (except F10,
F11, or F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
