Desktop Management

HP Intelligent Manageability provides standards-based solutions for managing and controlling desktops, workstations, and notebook PCs in a networked environment.

The capabilities and features of the seven key components of desktop management are:

■ Initial configuration and deployment

■ ROM flash

■ Security

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.

■ Usin g software deployment tools, such as Altiris Deployment Solutions, to replace the

preinstalled software with a customized software image.

■ Using a disk cloning process to copy the contents from one hard drive to another.

The best deployment method depends on your information technology environment and processes. The PC Deployment section of the Solutions and Services Web site

h18000.www1.hp.com/solutions/pcsolutions

deployment method. The Restore Plus! CD, ROM-based setup, and ACPI hardware provide further assistance with

recovery of system software, configuration management and troubleshooting, and power management.

3.2 ROM Flash

The computer comes with a reprogrammable flash ROM (read only memory). By establishing a setup password in Computer Setup (F10) Utility, you can protect the ROM from being unintentionally updated or overwritten. 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 http://www.hp.com/support.

Desktop Management

3.2.1 FailSafe Boot Block ROM

The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is a flash-protected section of the ROM that checks for a valid system ROM flash when power to the system is turned on.

■ If the system ROM is valid, the system starts normally.

■ If the system ROM fails the validation check, the FailSafe Boot Block ROM provides

enough support to start the system from a ROMPaq diskette, which will program the system ROM with a valid image.

To recover the system after it enters Boot Block recovery mode, complete the following steps:

1. If there is a diskette in the diskette drive, remove the diskette and turn off the power.

2. Insert a ROMPaq diskette into the diskette drive.

3. Turn on power to the system.

4. If no ROMPaq diskette is found, you will be prompted to insert one and restart the computer.

5. If the system successfully starts from the diskette and successfully reprograms the ROM, then the three keyboard lights will turn on.

6. Remove the diskette and turn the power off.

7. Turn the power on again to restart the computer.

3.2.2 Dual-State Power Button

With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, the power button can function either as an on/off switch or as a suspend button. The suspend feature does not completely turn off power, but instead causes the computer to enter a low-power standby. This allows you to quickly power down without closing applications and to quickly return to the same operational state without any data loss.

To change the power button’ s co nfiguration, complete the following steps:

1. Left click on the Start Button, then select Control Panel > Performance and

Maintenance > Power Options.

2. In the Power Options Properties, select the Advanced tab.

3. In the Power Button section, select the desired power button setting.

After configuring the power button to function as a suspend b utton, press the power button to put the system in a very low power state (suspend). Press the button again to quickly bring the system out of suspend to full power status. To completely turn off all power to the system, press and hold the power button for four seconds.

CAUTION: Do not use the power button to turn off the computer unless the system is not responding;

turning off the power without operating system interaction could cause damage to or loss of data on the hard drive.

3.2.3 Power Management

Power Management is a feature that saves energy by shutting down certain components of the computer when they are not in use, saving energy without having to shut down the computer.

With Advanced Configuration and Power Interface (ACPI) enabled for Windows 2000 and Windo ws XP, timeouts (the period of inactivity allowed before shutting do wn these components) can be enabled, customized, or disabled using the operating system.

1. In Windows 2000, left click on the Start Button, then select Settings > Control Panel >

Power Options. In Windows XP, left click on the Start Button, then select Control Panel > Power

Options.

2. In the Power Options Properties, select the Power Schemes tab.

3. Select the desired power scheme settings.

Use Display Properties to establish, modify, or disable Power Management settings for the monitor. To access Display Properties, right click on the Windows Desktop, then choose

Properties.

3.2.4 World Wide Web Site

Desktop Management

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.

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.

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. That is, when prompted for the power-on password, entering the setup password instead will allow access to the computer.

A network-wide setup password can be established to enable the system administrator to log in to all network systems to perform maintenance without having to know the power-on password, even if one has been established.

Ultra ATA Drive Guidelines and Features

4.1 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/De vice 0) or Slave (Driv e/Device 1) by its physical attachment to the cable.

If you purchase a third-party hard drive, refer to the documentation included with the drive kit to ensure proper cable installation and configuration.

All drives on a controller channel need to have their jumpers either in the cable-select mode or

✎

have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave (Drive/Device 1) position.

4.2 Ultra ATA Cables

When installing a second device on either the primary or secondary controller, you must use an industry standard 40-pin, 80-conductor Ultra ATA cable for optimal performance. These cables have a maximum length of 18 inches and a maximum distance of 6 inches between the two devices for a two-drive cable.

Drives operating at speeds faster than those of the Ultra ATA-33 devices require industrystandard 40-pin, 80-conductor cables to maintain the higher data transfer rates possible with the improved technology.

When using Ultra ATA-133, -100, -66, and slower -33 dri ves in the same system, each drive will operate at its appropriate data transfer rate.

4.2.1 Cable Layout

The faces of industry-standard cable connectors are color coded for easy recognition:

■ System board connector = blue face

■ Device 0 connecto r = black face

■ Device 1 connector = gray face

The color code of an industry-standard cable is valid only if the drive’s jumper is in the cable-

4.3 Drive Installation Guidelines

Most computer system boards have two ATA (IDE) controller channels with a dedicated connector for each controller. One controller is designated as the primary and the other as the secondary controller.

Each of the two controllers can have up to two devices attached to it. Each computer system may therefore have a maximum of four ATA/ATAPI drives. All drives are connected to these controllers using an industry-standard 40-pin, 80-conductor cable.

The industry standard 1.44 MB diskette drive has its own separate channel and is not included as

✎

a part of the maximum four drives.

Any drive attached to a controller must have a drive designation. If only a single drive is connected to a controller and its jumper is in the cable-select position, it is designated as the Master Drive (Drive/Device 0) by its attachment to the Drive/Device 0 cable position. If two cable-selected drives are connected to a single controller, one will be designated by its attachment to the cable as the Master (Drive/Device 0) and the other as Slave (Drive/Device 1).

For optimal performance of a computer system, all drives need to be attached to the ATA controllers in a specified sequence. This sequence is determined by the device class of the drives and by specific attach sequence rules.

4–2 359782-002 Service Reference Guide, dx2000 uT

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.

General Attach Guidelines

■ The lower the device class number, the faster the device and the more bandwidth required.

■ Drives installed in the Device 0 positions on both the primary and secondary controllers

receive the greatest possible bandwidth.

■ The bootable ATA hard drive should always be installed on the primary controller in the

Device 0 position.

Service Reference Guide, dx2000 uT 359782-002 4–3

Ultra ATA Drive Guidelines and Features

The attach sequence rule may also be stated in table format:

Sequence Description

1 The lowest class drive - bootable hard drive recommended.

2 If only two drives, the last drive goes here; otherwise the lowest class of the

remaining drives.

3 If only three drives, attach the final drive here. If a fourth drive exists, attach the

lowest class drive here.

4 If there is a fourth drive, attach the final drive here - the drive with the highest

class number of all devices.

*If there are three or more devices, two or more of which are hard drives, two hard drives should be attached to the primary controller first before following the General Attach Sequence Rule.

The rules allow for:

General Attach Sequence Rule*

■ Keeping the hard drive on a separate controller channel maximizes drive performance until a

fourth device is added.

■ Keeping the hard drives and removable media drives on separate controller channels

maximizes compatibility.

■ Keeping the hard drive and the writable optical drive on separate controller channels

maximizes optical drive reliability.
