Support for specific features described in this guide may vary by model or software version. 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.
This is important to ensure the operating integrity of the computer. Should you need or want to upgrade your ROM, you may: ■ Order an upgraded ROMPaq™ diskette from HP. ■ Download the latest ROMPaq images from 3.2.1 FailSafe Boot Block ROM...
HP has made the task of locating, accessing, evaluating, and installing the latest support software easier. You can download the software from the latest device drivers, utilities, and flashable ROM images needed to run the latest Microsoft Windows operating system on your HP computer.
Desktop Management 3.3 Security 3.3.1 Password Security The power-on password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the power-on password.
The power-on password and setup password may also be changed using the Security options in Computer Setup. Service Reference Guide, d200 key at the appropriate time, you must turn the computer off, then on key again to access the utility. 336493-004 Desktop Management Enter. Enter 3–5...

Ultra ATA Drive Guidelines and Features Ultra ATA Jumpers Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory pre installed, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
Ultra ATA Drive Guidelines and Features Single-Drive Cable System Board Blue Face Two-Drive Cable System Board Blue Face On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector.
4.3.1 Device Classes In order to determine the best drive attach sequence, ATA/ATAPI drives are segregated into four different classes based upon the bandwidth demands they place on an ATA controller. The most demanding devices are in Class 1 and the least demanding are in Class 4. Class 1 Hard High Speed...
Ultra ATA Drive Guidelines and Features The attach sequence rule may also be stated in table format: Sequence The lowest class drive - bootable hard drive recommended. If only two drives, the last drive goes here; otherwise the lowest class of the remaining drives.
Example 1: Three Device Installation Sample A system has three devices: Ultra ATA-100 hard drive, CD-ROM drive, and a DVD drive. Using the Device Class Table in ■ Ultra ATA-100 hard drive = Class 1 ■ DVD drive = Class 2 ■...
Computer Setup (F10 Setup). 4.4 SMART 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.
4.5 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.
Identifying the Chassis, Routine Care, and This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service.

5.2.2 Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ■ To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
Identifying the Chassis, Routine Care, and Disassembly Preparation ■ Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces. ■ Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam. ■ Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive. 5.2.5 Recommended Materials and Equipment Materials and equipment that are recommended for use in preventing static electricity include: ■...

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.
Identifying the Chassis, Routine Care, and Disassembly Preparation ✎ As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage. Service Reference Guide, d200 336493-004 5–7...
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.
Removal and Replacement Procedures— Adherence to the procedures and precautions described in this chapter is essential for proper service. After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify that all components operate properly. ✎ Not all features listed in this guide are available on all computers.

Systems Using Single or Dual Channel Memory The d200 series computers come with Double Data Rate-Synchronous Dynamic Random Access Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs). The memory sockets on the system board can be populated with industry-standard DIMMs and come from the factory with at least one preinstalled memory module per computer.
Memory Maximum operating speed is determined by a combination of the CPU and the type of memory used. Refer to the table below for the optimum combination. Front-Side Bus (MHz) 800* *Select models only. In single channel mode, the maximum operational speed is determined by the slowest DIMM in the system.
