3 Desktop Management ✎ Support for specific features described in this guide may vary by model or software version. 3.1 Initial Configuration and Deployment HP computers come with a preinstalled system software image. After a brief software “unbundling” process, the computer is ready to be used. A customized software image may be deployed by installing additional software applications after unbundling the preinstalled software image.
Desktop Management 1. Remove all removable media and turn off the power. 2. Insert a diskette containing the desired BIOS image file in the root directory. The media must be formatted using the FAT32 file system. 3. Turn on power to the system. The failsafe Boot Block BIOS will attempt to start the system from a bootable device. If no bootable device is found, an error message will appear. 4. Remove the removable media used to upgrade the BIOS. 5. Turn the power on to restart the computer. 3.2.
Desktop Management 3.2.4 World Wide Web Site When making the transition to new or revised operating systems, it is important to implement the support software designed for that operating system. If you plan to run a version of Microsoft Windows that is different from the version included with your computer, you must install corresponding device drivers and utilities to ensure that all features are supported and functioning properly.

4 Serial and Parallel ATA Drive Guidelines and Features ATA = SATA ✎ Serial Parallel ATA = PATA HP does not support the use of a PATA (IDE) hard drive on this model of computer. 4.1 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 5V, 12 V Jumpers for configuring drive N/A Data transfer rate 1.
Serial and Parallel ATA Drive Guidelines and Features 4.2 SATA Hard Drive Cables 4.2.1 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. 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.
Serial and Parallel ATA Drive Guidelines and Features 4.3 PATA Device Information This information applies to optical drives in a computer having one or two SATA drive controllers and a single PATA drive controller. PATA hard drives are not supported on these models. 4.4 PATA Cables 4.4.
Serial and Parallel ATA Drive Guidelines and Features Each drive attached to a channel must have a drive designation. If a drive is attached to the Device 0 cable position and its cable-select jumper is present, the drive is designated as Device 0. Similarly, if a drive is attached to the Device 1 cable position and its cable-select jumper is present, the drive is designated as Device 1.
Serial and Parallel ATA Drive Guidelines and Features Drive/Partition Capacity Limits Maximum Size File System Controller Type Operating System Partition Drive FAT 32 ATA Windows 2000/ XP 32 GB 128 PB NTFS ATA Windows NT/2000/XP 2 TB 128 PB 4.
Serial and Parallel ATA Drive Guidelines and Features 4.8.2 Native Mode The native mode is used to access devices attached to additional ATA controllers and is not supported by many legacy operating systems. Addresses are assigned by PCI Plug-n-Play BIOS and the IRQ is shared with multiple controllers. Base Address Registers for the Command and Control Block are found in the PCI Configuration Space.
5 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. Ä 5.1 CAUTION: When the computer is plugged into an AC power source voltage is always applied to the system board.

Identifying the Chassis, Routine Care, and Disassembly Preparation 5.2 Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy staticsensitive 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.
Identifying the Chassis, Routine Care, and Disassembly Preparation 5.2.3 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.
Identifying the Chassis, Routine Care, and Disassembly Preparation 5.3 ■ Static awareness labels ■ Wrist straps and footwear straps providing one-megohm +/- 10% resistance ■ Material handling packages ■ Conductive plastic bags ■ Conductive plastic tubes ■ Conductive tote boxes ■ Opaque shielding bags ■ Transparent metallized shielding bags ■ Transparent shielding tubes Routine Care 5.3.1 General Cleaning Safety Precautions 1.
Identifying the Chassis, Routine Care, and Disassembly Preparation 5.3.3 Cleaning the Keyboard Follow all safety precautions in Section 5.3.1, “General Cleaning Safety Precautions,” before cleaning the keyboard. To clean the tops of the keys or the keyboard body, follow the procedures described in Section 5.3.2, “Cleaning the Computer Case.” When cleaning debris from under the keys, review all rules in Section 5.3.
Identifying the Chassis, Routine Care, and Disassembly Preparation 5.4 Service Considerations Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer. 5.4.1 Power Supply Fan The power supply fan is a variable-speed fan based on the temperature in the power supply. Ä CAUTION: The cooling fan is on when the computer is “ON” or in “Suspend to RAM” modes.
Identifying the Chassis, Routine Care, and Disassembly Preparation 5.4.4 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.
