Protecting and Using Your PC

This chapter presents an overview of the security features provided with the HP PC and a list of tasks that should be carried out on a regular basis to protect and look after your files. This section also includes information about the different features available with the HP Enhanced Keyboard.

2 Protecting and Using Your PC

Security Features

The HP PC has many security features to protect stored files, and to prevent unauthorized operation of software applications.

HP Setup Program

The following security features are set by using the HP Setup Program:

• User password.

• Supervisor password (system configuration protection).

• Power-on prompt, with password.

For further information on how to use the program and its features, refer to chapter 3, “

The HP Setup Program”.

Protecting Your PC from Virus Infections

A virus is a small part of a program that is capable of inserting itself in the code of another program, then spreading from this program to another, and so on. Viruses can have different impacts on your PC, from displaying annoying messages to damaging data. The regular use of updated antivirus software is the best way to protect your PC against a virus. You should regularly scan the hard disk and any other disks you use for virus infections.

Your PC is installed with the VirusScan antivirus software. McAfee VirusScan and VShield can be accessed from the HP data protection center. McAfee VirusScan also includes an on-access scanning component, Vshield, which intercepts and scans programs before they are executed. However, Vshield will only be activated once you have agreed to the license agreement that is displayed the first time you use VirusScan.

2 Protecting and Using Your PC

Maintaining Your Disk and Files

To ensure that you have a good and efficient working environment, you can use the tools provided with your HP PC to protect all your files and keep your system at its highest possible performance level. It is recommended that you schedule maintenance tasks on your PC on a regular basis.

Improving File Access Time

As programs are continually reading or writing to the hard disk, fragmentation eventually occurs, meaning that files are stored in non-contiguous sectors. Although this does not have any affect on the files themselves, it does take the computer a longer time to access fragmented files for reading and writing operations. It is therefore advisable to run a disk defragmenter on a regular basis, as this consolidates files and thereby improves file access time.

Note

This tool can be accessed from the HP data protection center.

Refer to the Windows 95 documentation for information on how to use the disk defragmenter utility.

It should be noted that when using a defragmenter you can safely use your computer to work on other applications, but response time will be slower than normal.

2 Protecting and Using Your PC

Maintaining Your Disk and Files

Increasing Disk Space

If there is a need for some extra space on the disk, this can be met by compressing the files on the disk. Disk drives can also be compressed. For most programs, a compressed drive appears as a real disk drive.

The Windows 95 utility DriveSpace can compress and manage drives compressed with DriveSpace or DoubleSpace.

To run the Windows 95 DriveSpace utility:

1 Click the Start button.

2 Select Programs, then Accessories, then System Tools.

3 Select DriveSpace, then click the drive you want to compress.

It should also be noted that whenever a file or directory is deleted, it is moved to the Windows 95 Recycle Bin. You should check this regularly and delete any unwanted files. The Recycle Bin can be configured to delete files either immediately it receives them or, alternatively, only when you request it to do so.

To configure the Recycle Bin:

HP/Phoenix BIOS Description

The System ROM contains the BIOS1 (System BIOS, video BIOS and low-option ROM) and the power-on self-test routines that allow you to view the results of the diagnostics and provide you with error corrective-action messages if necessary.

The System BIOS can be updated by running the PHLASH utility with the latest BIOS firmware. This can be ordered from HP or downloaded from one of the HP online services.

Power-On Self-Test (POST)

The Power-On Self-Test (POST)is executed each time the system is turned on or a reset is performed. The POST process checks that system components are operating correctly and initializes certain system parameters.

Beep Codes

If a terminal error occurs during POST, the system issues a beep code before attempting to display the error. Beep codes are useful for identifying the error when the system is unable to display the error messages.

Business Communications Options

Depending on the HP PC you have purchased, you may have built-in advanced communications and telephony options installed.

4 Business Communications Options

Introduction

The communications option provides you with hands-free communication and multimedia functions, through the use of a headset and audio devices. It also provides communications tools that give you the possibility to send and receive faxes, receive voice messages, and access Bulletin Board Systems (called BBSs). You can upload and download files and computer software to and from a BBS.

What you will probably appreciate most in the communications option is its telephone answering capabilities and the possibility for everyday modem-to-modem exchange of business faxes and files.

Service providers, including America Online, CompuServe, GEnie, and Prodigy, supply access to services such as electronic mail, airline reservations, banking and finance, and computer support forums.

In addition, certain service suppliers can provide you with access to worldwide networks such as the Internet. You can use specialized navigation tools like Web browsers to roam through a vast realm of interconnected information systems.

Your communications option is fully compliant with both U.S. and international communications standards. Compatibility with these standards ensures that you can communicate with other modems anywhere in the world.

What Is a Modem?

A modem allows your computer (the local station) to communicate with another computer (the remote station) through an analog telephone line. Each system must have its own modem.

4 Business Communications Options

Introduction

Your communications option connects your HP PC to:

- telephones

- fax machines

- networks

- other systems with modems

4 Business Communications Options

How Your Modem Works

In data mode your Modem takes advantage of the typical network configuration found when an analog subscriber connects to a digitally connected server. Because it bypasses the analog-to-digital conversion in the downstream path, the modem can use nearly all of the available 64 kbps network bandwidth.

Data sent by the modem (which is typically less speed sensitive) travels at the standard V.34 rate. Your Modem is 56 kbps capable. However, current regulations limit download speeds to 53 kbps.

Modem Features

As well as combining computer and telephone technologies, your communications option has the following features:

• High speed Internet access at up to 56 kbps.

• High speed data transfer at up to 33,6 kbps.

• High speed fax send and receive rates of up to 14,4 kbps.

• Voice capability (by using a sound card and software enabled for voice modem support).

4 Business Communications Options

Software Settings

The modem card in your computer supports Plug and Play. This means that, when the card is installed or reinstalled, Windows 95 is able to automatically configure various software settings to enable the computer to communicate with the card:

• The IRQ (Interrupt Request) line is the signal line a device uses to notify your computer’s microprocessor that it wants

to send or receive data for processing.

• I/O addresses (or I/O address ranges) enable your computer’s microprocessor to access various peripheral devices

connected to your system when sending or receiving data.

The following table gives the preferred settings of the card. Windows 95 may change these settings when a card is installed or reinstalled to avoid a conflict between the different accessories on your computer.

Modem Interface:

The operating system may change these settings when a board is installed or reinstalled if another peripheral device uses the same I/O address or interrupt setting as the modem card (known as a hardware conflict).

I/O Address Range:110H to 117H Port:COM3 IRQ Line:IRQ 9

4 Business Communications Options

Software Settings

Viewing the Software Settings

All of the settings are software-configurable. There are no jumpers to set on the card. Plug and Play means you should never experience a conflict with the settings. To view the modem settings:

1 Click the Start button and select Settings, then Control Panel.

2 Click the Modems then the Diagnostics tab.

3 In the list of Ports, you will see the COM port set for the modem. Select this and click More Info... This window then

displays the modem settings.

Caution

As many applications are designed to work with your default settings, you are advised not to change the settings unless you are very familiar with PC configuration.

Using Sound on Your PC

Depending on the HP PC you have purchased, you may have a sound card installed. This section helps you to set up your sound programs and to solve any problems that you may encounter.

5 Using Sound on Your PC

Why Do I Need Sound?

Sound is an essential element in multimedia computing. But just what is “multimedia computing”, and what can you do with it? With the multimedia sound option in your PC, you can:

❒Run training applications that use speech and music.

❒Use presentation software to create and run promotional or information displays.

❒Run multimedia applications, such as games and encyclopedias, that use sound either on your computer or from the

Internet.

5 Using Sound on Your PC

Why Do I Need Sound?

Furthermore, using the standard audio software on your computer, you can:

❒Record speech or music (as “wave files”) and embed these sounds in other programs. This is useful for creating training

programs.

❒Play music CDs or MIDI files on your computer (MIDI files are a way of storing music, especially music created by

keyboard instruments).

❒Record, play, and edit pieces of music or sound (stored as wave files).

5 Using Sound on Your PC

Running the Audio Programs

Your HP PC has full audio capability. The sound card’s features can be used by any other application that supports standard PC audio capability.

For example, you can add computer software for creating your own multimedia business presentations and training programs, building in voice-over, graphics, and audio enhancements.

Your computer includes several audio software tools to enable you to have complete control of the audio input to these applications:

1 Click the Start button on the taskbar.

2 Select Programs, then Accessories, then Multimedia.

A selection of audio programs appears:

CD Player For playing music CDs. This program gives you the normal hi-fi display to show number of tracks, elapsed playing time, and

so on.

Media Player To play either MIDI files, music CDs or sound files. The MIDI player makes use of the sound card’s built-in synthesizer. Sound Recorder To record sounds from various sources as wave files. Volume Control To control the input and output volumes of the other players and sound recorder.

Note

Warning

The output volume may initially be set to zero in the audio software. If you don’t hear any sound, adjust the volume using the audio software.

If using a headphone for testing your sound card, do not connect the headphone to the SPK output. Refer to

“Connecting Audio Devices to the Rear Panel” on page 82 for further details.

How to Use a Headset

For recording and listening to messages, a headset must be used, and is connected directly to the sound card.

On the headset there are normally two connectors that have to be connected to the sound card: one for the microphone and the other for the speaker.

The following illustration shows how to connect a headset to the sound card. (Note: Your headset might be different to the one shown).

Adjust the microphone arm position to obtain the best sound quality.

5 Using Sound on Your PC

How to Use a Headset

When the telephone line and headset are connected, you are ready to use the communications software. The software can be accessed from the HP communication center. For further information concerning the communications software, refer to the documentation Communications.

Warning

To avoid discomfort from unexpected noise or static, always turn down the volume before connecting the headphones or speakers to your computer. Whenever you wish to use the headphones, first place them around your neck and check that the volume is turned down. Then, put on the headphones and slowly increase the volume by using the Audio Mixer Applet or the enhanced keyboard until you find a comfortable listening level, where the sound is clear, without being too loud. Listening to loud sounds for prolonged periods of time may permanently damage your hearing.

Volume Control

The volume for the headset can be controlled either by using the communications software (audio mixer and telephony applications) or by using the enhanced keyboard. Whichever method you use, the volume adjustment is automatically made to the other.

Communications Software

To obtain the best audio quality for yourself and the caller, it is recommended that you configure the audio mixer and telephony applications.

If you are listening to a CD-ROM when you receive a telephone call, another feature automatically puts your CD-ROM on Mute while you have your conversation. When finished, the CD-ROM volume automatically returns to its initial setting.

5 Using Sound on Your PC

Connecting a MIDI Keyboard

You store your arrangements in a MIDI file, which is like an orchestral score—it can contain the sequence of notes for many different instruments, indicating the pitch and duration of each note and the sort of instrument it should sound like.

Track Name Loop Key Time Port Channel Patch Volume Size

1 Lead

2 Harmony 1 0 0 1:SB16 2 Clarinet ... 295 3 Bass 2 15 2:External 3 Bass ... 175 4 Trombone 2 15 1:SB16 4 Trombone 85 260

5 Jug 2 15 1:SB16 5 Bottle blow ... 303

1 0 0 2:External 1 Electric Piano ... 301

Each instrument is played back on its own channel. You can play back some channels through your computer and some through your keyboard instrument.

Setting Up

Your keyboard, Windows 95 settings, and sequencer program must all be set up correctly for you to record and play back music satisfactorily.

It’s difficult to give precise instructions here for setting up, as the steps depend on your keyboard and on the music software you are running. For more specific instructions, refer to the documentation that came with your keyboard and software. However, here are some general guidelines that should help you get started and solve certain problems later.

1 Connect your keyboard instrument to the rear panel of your PC via a MIDI cable, as shown on page 68

2 Direct your computer’s MIDI output to a playback device as follows:

a Click the Windows 95 Start button.

b Select Settings, then Control Panel.

c Double-click the Multimedia icon .

d In the Multimedia Properties dialog box, click the MIDI tab.

• To play back all the channels through the same synthesizer, select Single instrument. Then select either Internal

OPL2/OPL3 FM Synthesis (to play back through the computer’s sound synthesizer) or HP MPU-401 Device (to play back through your keyboard instrument). If you have several MIDI instruments, select the particular instrument for playback. (You can first set up each instrument with a distinct name by clicking the Add New Instrument button and following the wizard’s instructions.)

• To divide the channels between synthesizers, select Custom configuration and then click Configure. Then, select

each channel in turn, click Change, and select a synthesizer for that channel. By clicking Save As, you can save your configuration with a particular name.

5 Using Sound on Your PC

Connecting a MIDI Keyboard

This configuration feature is often called a MIDI mapper, because it maps the MIDI channels onto the synthesizers.

e Click OK to save your changes.

Note

3 In your sequencer program, select all the potential MIDI devices you may use for recording (input port) and playback

(output port). Depending on your program, these may be selectable through a Settings menu.

For example, select both the internal synthesizer and the MIDI output port if you intend to divide the channels between the two playback devices.

The settings in your sequencer program (step 3) may override the settings in Windows 95 (step 2).

5 Using Sound on Your PC

Connecting a MIDI Keyboard

4 In your sequencer program, for each track select an output port, a channel number, and a patch number or name:

• The output port defines where the track is to be sent for playback: to the computer’s internal synthesizer or to your

keyboard instrument. Bear in mind how many different instrument voices your keyboard is capable of playing back at the same time.

• The channel number lets you “tune in” a particular keyboard or module to this track. Do not select the same channel

number for two different tracks unless they use the same patch (voice).

• The patch is the instrument voice. Your sequencer program may let you select a MIDI patch number or an instrument

name.

5 On your keyboard instrument, select a channel number or numbers on which to receive MIDI information. The channel

number(s) will depend on which track(s) you want to play back through your keyboard, as set up in your sequencer program. If in doubt, select channels 1, 2, 3, and so on. You can usually change the channel number(s) as you play back a piece of music.

5 Using Sound on Your PC

Software Settings

The sound card in your HP PC supports Plug and Play. This means that, when the card is installed or reinstalled, Windows 95 is able to automatically configure various software settings to enable the computer to communicate with the card:

• The IRQ (Interrupt Request) line is the signal line a device uses to notify your computer’s central processor that it

wants to send or receive data for processing.

• The DMA (Direct Memory Access) channel is the signal line a device uses to transfer data directly to the computer’s

memory.

• I/O addresses (or I/O address ranges) enable your computer’s microprocessor to access various peripheral devices

connected to your system when sending or receiving data. There are several such devices on your sound card.

The following table gives the preferred sound settings of the card. Windows 95 may change these settings when a card is installed or reinstalled to avoid a conflict between the different accessories on your computer.

Audio Interface:

MPU-401 UART MIDI Interface: (Disabled by default)

Joystick Interface:

Stereo Music Synthesizer

I/O Address Range:220H to 22FH Joystick Connector:Enabled IRQ Line:IRQ 5 Low DMA Channel:1 High DMA Channel:3

I/O Address Range:300H to 301H IRQ Line:IRQ 9

I/O Address Range:200H to 207H

I/O Address Range:388H to 38BH

5 Using Sound on Your PC

Software Settings

The operating system may change these settings when a card is installed or reinstalled in the following cases:

• Another peripheral device is using the same I/O addresses, DMA channel, or interrupt setting as the sound card (known

as a hardware conflict).

• Another joystick/game connector is already in use in your system.

Viewing the Software Settings

All of the audio settings are software-configurable. There are no jumpers to set on the card. Plug and Play means you should never experience a conflict with the settings. You can view settings through the Device Manager, as follows:

1 Click the Start button and select Settings, then Control Panel.

2 Open System and click the Device Manager tab.

3 In the list of devices, expand the line Sound, video and game controllers. You will see the audio driver HP Audio Device.

Select this and click Properties.

4 Click the Resources tab. Now you can view the settings. You may need to scroll the list to see all of the settings.

Caution

5 To change a setting, first clear the checkbox Use Automatic Settings. Then select the resource type and click Change

Settings.

6 Select a new setting using the scroll buttons and click OK.

7 Click OK again at the Properties window, and then click Yes at the confirmation message (but please read the message

first!).

As many applications are designed to work with your default audio settings, you are advised not to change the settings unless you are very familiar with PC configuration.

5 Using Sound on Your PC

Playing CDs

The CD Player program acts in the same way as the CD unit in a hi-fi system. It lets you play music CDs, so you can listen to music while working. In addition, if you’re creating an audio-visual presentation, you can add CD music or sounds to your presentation.

1 Click the Start button on the taskbar.

2 Select Programs, then Accessories, then Multimedia, then CD Player.

Insert an audio CD in the CDROM drive, and then click here to play it.

To stop playing the CD, click this button.

To eject your CD from the drive, click here.

These buttons let you skip tracks or fast forward/rewind, like on a hi-fi unit.

You can also select a random order of playing tracks, or continuous play (the CD plays again and again). Look in the Options menu for these features. You can also compile a playlist of tracks for a CD. This means you can specify which tracks on a CD to play, and in which order, so that the CD Player skips the tracks you don’t want to hear. Find this option in the Disc menu.

Note

Make sure your headset is plugged into the CD disk drive before listening to a CD.

5 Using Sound on Your PC

Recording Your Voice

By creating your own sound recordings, you can customize your computer sounds, embed speech in documents, or create a sound track for a presentation.
