3.)  What Does it do?

        This patch will update PowerHouse to version 1.1.

        In this version, A game length option will give you a choice, in
        years, of the length of the game.  This gives you the ability to
        control the time you are given to play. You are given the choices of
        20, 40, 60, 80, or 100 years.

        The following Error Messages are fixed:

        General Protection Faults:
                Power caused a general protection fault in POWER.EXE
                Power caused a general protection fault in USER.EXE

        Errors with Pipes are now fixed. Pipes can be removed without causing
        errors.

        Pallate Issues In Windows 95 have been addressed.

4.)  Additional Gameplay help

        As described in the manual, you can turn the ENN video segments off if
        you find them distracting. If they are off you will still get
        necessary information - but via quicker, still-pictures. You can
        switch ENN off, on, or set it to "MIX". This setting will play full
        ENN video for occasional news stories only, and will usually give you
        a static picture.

        For the toughest challenge, set difficulty to "Hardest" from the
        'Set The Challenge' box, and/or give yourself less starting cash.
        Difficulty level affects the cleverness of the AI players, and sets
        whether you first, second, third or fourth each turn.
        There is a display toward the bottom right of the main screen
        (just under the spinning E-mail 'e'). It serves as a rough guide to
        how well the four PowerHouses are doing, in three different areas.
        These areas are: current cash, energy supplied and environmental
        damage caused. Switch between these 3 areas by clicking on the icon
        to the left of the horizontal bar chart. The bar chart now displays
        performance levels of all PowerHouses in the area chosen. The number
        to the right of the chart is your standing in the chosen area.

        Sometimes you might make more energy in a territory than you can sell
        there.  If so, you can  move the excess energy to other territories
        using Transformers. Build a chain of Transformers between any square
        in the destination territory, and a square in the excess production
        territory.  Transformers have a range of 5 - they will take energy
        from production sites or other Transformers, so long as these are
        five or less squares away.

        Each Transformer in the chain, even the first one, loses a percentage
        of its input, so make your chain with as few Transformers as possible.
        At tech level 1, you lose 23% at every Transformer. Each transformer
        has a capacity too. Again at tech level one, a Transformer site will
        only take in 60 units of energy per Transformer rig on that square.
        The Energy Needs screen shows the amount of energy lost to
        Transformers: This figure includes both through efficiency loss along
        the chain, and loss where more energy is sent to a transformer site
        than it has capacity for. Note: the 'Energy sold via Transformers'
        figure means the amount taken from this territory, and sold elsewhere.
        The 'Energy brought by Transformers' means the amount taken from other
        territories, and sold in this one.  You can see your networks in detail
        by using the Power Network overlay option. This shows all your
        Transformers, connected by yellow lines. Green dots shows where your
        network ends, red dots show Transformers which pass energy on.
        Excess energy will be picked up and moved along the network until it
        reaches a Transformer which is sitting in a territory with unmet need.
        Then it will be sold, even if it hasn't reached the end of your network.
        Use the Utility Sites Report to check up on your Transformers.

5.)  General Troubleshooting Steps for Sierra Games (DOS or Windows)
         
        NOTE: Before you begin troubleshooting, we strongly recommend
        completing steps 1 through 3 before doing anything else. This will
        help insure that the game is installed under an optimal environment
        and eliminate many basic problems. Corrupted or bad installations can
        cause a variety of problems; it is best to eliminate this possibility
        before you begin additional troubleshooting steps.  The following
        steps can be used on any Sierra On-Line's Family Product unless
        otherwise indicated.

        1.) Check for Corrupt Files or Other problems on the hard drive:
                Before you do anything else, run one of the following DOS
                Commands (listed below) on the hard drive where the game is
                installed. These commands will check for lost allocation
                units, corrupted files, cross-linked files, and other disk
                errors which can corrupt files and/or the game's installation.
                These commands will also correct  the errors they find. For
                more information on these commands consult your DOS manual.

                CHKDSK /F <Enter>
                (This command is for users running MS-DOS 6.0 or earlier)

                SCANDISK <Enter>
                (This command is for users running MS-DOS 6.2 or higher)

        2.) Check hard disk space:
                Run the CHKDSK command (regardless of the DOS version you are
                using) and check the available hard disk space ("Bytes
                Available on Disk"). Make sure you have sufficient space on
                the hard drive to install the game.  Games installed on a
                compressed hard drive will need twice as much compressed disk
                space.  (Example: If you use any disk compression, and you
                wish to install a game that requires 10 MB  of disk space, be
                sure you have AT LEAST 20 MB of space available, preferably
                25 MB to allow a safe margin.)  After installation, it is best
                to have at least 3 MB of disk space available (roughly 5 under
                a compressed environment).

        3.) Re-install the program:
                After completing the above steps, it is a good idea to install
                the game.  Delete all files and sub directories for the game
                from the hard drive.  It is highly recommended that you  boot
                up with a basic boot disk prior to re-installing the game.
                This will help insure that no memory resident programs
                (especially virus checkers) will interfere with the game's
                installation.

        4.) Manually install the program (Some Programs):
                Try a manual installation if all else fails.  The instructions
                are available in the README file of many of the newer
                products, on the Sierra On-Line's BBS, or available by fax
                from Technical Support.  NOTE: not all products can be
                manually installed.

        5.) Check Available Memory:
                A) DOS Programs:
                        Games require different types and amounts of memory.
                        If you ever receive an error messages from a DOS
                        program like "Out of Hunk", "Out of Heap Space", or a
                        report of insufficient memory, then you will need to
                        free up more memory to play the game. You can check
                        to see how much memory you have available and how it
                        is configured by typing MEM (then press ENTER) at your
                        DOS prompt. Make sure that your system's memory is
                        configured to provide enough memory for the game to
                        function properly. If it is not, or you have
                        encountered any of the above messages we recommend
                        creating a boot disk for the game.

                B) Windows Programs:
                        You can check available memory in Windows by selecting
                        HELP from the Program Manager, then choose "About
                        Program Manager".  You will see a Dialog box
                        containing the amount of memory in Windows.  Also,
                        check the size of your Windows Swap file and consult
                        the section IIb "Configuring Windows for Sierra
                        On-Line's Programs" for complete instructions on
                        checking and establishing a Swap file.  A boot disk
                        can also help with memory problems under Windows,
                        which takes us to our next suggestion....

        6.) Make a boot disk!
                The boot disk is an important troubleshooting step.  Along
                with freeing up more memory, using a boot disk creates a clean
                environment that helps to isolate potential conflicts.  We
                also recommend using boot disks for Windows.  Many of our
                current DOS games have an automatic boot disk maker you can
                access by running the INSTALL program and choosing "Make a
                Bootable Floppy Disk" from the menu.  You will need a high
                density disk that fits in your A: drive.  The boot disk is an
                important trouble shooting step.  Along with freeing up more
                memory, using a boot disk creates a clean environment that
                helps to isolate potential conflicts. We also recommend using
                boot disks for Windows.  We have a disk named BDALL which
                contains a boot disk creator program. You can also download
                this file from our BBS at (206) 644-0112, or you can call
                Technical Support at (206) 644-4343 and request the disk be
                sent to you.

        7.) Sound Card Problems:
                Configuring your sound card and the game's sound drivers
                correctly is important. If the sound card is not configured
                properly, or an incorrect driver or setting is chosen when
                your Sierra program is installed, your game may lock-up or
                give you error messages. Consult section III, General Sound
                Card Troubleshooting Steps for a list of steps to help
                resolve Sound Card problems.

        8.) Mouse Drivers (DOS programs only):
                Sometimes incompatible mouse drivers can cause graphics
                distortion, lock-ups and other problems.  If the game you are
                using does not require a mouse, create a boot disk and REM
                out the Mouse line in either the CONFIG.SYS or AUTOEXEC.BAT
                file on the boot disk.  Otherwise, use a different mouse
                driver or contact the mouse manufacturer for more
                troubleshooting information.


II. Configuring Windows for Sierra On-Line's Games
        Sometimes you may need to make changes or adjust your Windows
        configuration in order to run your Sierra programs. This document
        contains steps for three of the most common Windows Setup issues that
        are encountered by our customers: Changing Video Drivers, Setting up
        a Swap file, and Setting up the MIDI Mapper.

  IIa. Changing Video Drivers
        IMPORTANT NOTE: While we can tell you HOW to change your video
        driver, we cannot determine the appropriate driver for the specific
        brand and model of video card you have installed in your computer.
        When selecting a video driver, you must select a video driver
        specific to the video card installed in your computer.  Please refer
        to documentation that came with your specific video card installed in
        your system.

        Most Sierra On-Line and Brightstar Windows programs require 256
        colors.  While most video cards are capable of displaying 256 colors,
        Windows must be setup to use a 256 color display driver (Windows
        default is 16-color). If you are running Windows with a 16 color
        driver and you try to run one of our games that requires 256 color
        graphics, you will most likely receive the error message "Your
        current Display Driver is not supported by this game." Additionally,
        running a high color driver, like 32,000 colors or more, can
        sometimes generate a similar error message, or cause graphics
        distortion or lockups. It is for this reason that we recommend
        running Windows with a 256-color driver for optimal results with
        Sierra On-Line's Windows programs. Below is a step by step set of
        instructions for changing your video driver in Windows.
        Most often, when you purchase a new video card, the Windows drivers
        will be included on floppy disks. If the video card came pre-installed
        with an entire computer system, the drivers should have been installed
        for you by the hardware manufacturer, or included on floppy disks. If
        you choose an incorrect video driver when changing drivers, Windows may
        not boot. Should this happen, don't panic. You can restore your
        previous video driver by running the SETUP program from the WINDOWS
        directory, in DOS. (Just go to your C:\WINDOWS directory when you are
        in DOS and type SETUP, then press ENTER).

        From within the PROGRAM MANAGER:
                1.) Double-click the MAIN program group icon.
                2.) Double-click the WINDOWS SETUP icon.
                3.) You will see a dialog box with "Display" "Keyboard",
                        "Mouse", and "Network".
                4.) On the menu bar, click on OPTIONS..., then go down to
                        CHANGE SYSTEM SETTINGS.
                5.) You will see another dialog box, similar to the previous
                        one. Click on the down arrow to the right of
                        "Display". You will get a list of Video drivers
                        available to you. You can use the scroll bar to
                        scroll up and down the list of drivers. Select a 256
                        color driver appropriate for your video card. If you
                        are installing the driver from floppy disks or some
                        other source, choose "Other Display", and you will be
                        instructed to type a path to the driver, or to insert
                        the disk with the drivers into your floppy drive.
                        If you have any problems changing your video driver
                        or need more information, consult your Windows
                        documentation, or contact the hardware or video card
                        manufacturer. Additionally, if you do not have the
                        appropriate video drivers available to you, you will
                        need to contact the hardware or video card
                        manufacturer to obtain them.

   IIb. Setting up a Windows Swap file (Virtual Memory)

        Virtual Memory, also referred to as a Swap file, is essentially hard
        disk space that is used as memory. If you have a computer with 8 MB
        of RAM, and a 4 MB Swap file, Windows treats that as 12 MB RAM.
        Sometimes if you do not have enough Extended memory available to run
        a Windows program, Windows may be able to use Virtual Memory instead.
        Some Sierra programs require a small amount of Virtual memory in
        order to run properly.
        If you are experiencing "Insufficient Memory" messages in Windows,
        then it would be a good idea to check your Virtual Memory. (We also
        recommend a Windows boot disk for these problems as well.) We
        typically recommend a Swap file of around 4096k.
        To check and set up your Virtual Memory (Swap file):
                From within the PROGRAM MANAGER:
                1.)     Double-click the MAIN program group icon.
                2.)     Double-click the Control Panel icon.
                3.)     Double-click the 386 ENHANCED Icon.
                4.)     You will see a dialog box. Click on the button
                        "Virtual Memory". This will bring up a second dialog
                        box that will tell you the size, type (permanent or
                        temporary), and the drive your Swap file is located
                        on. To change the drive that the Swap file is located
                        on, or the Type of Swap file being used, you can
                        click on the arrow next to those options to view your
                        other choices. You will also see the following
                        information listed: Space Available (the amount of
                        hard drive space available for use as a Swap file),
                        Maximum Size (the largest size of Swap file
                        available), Recommended Maximum Size (The largest
                        setting of Swap file Windows will allow you to use),
                        and New Size (You can specify the size of the Swap
                        file by typing it into this box).
                5.)     IF you wish to change the size of your Swap file,
                        you can type the size in the New Size box. Then click
                        on OK. Windows will ask you if you are sure you wish
                        to make changes. Click on "Yes". You will then need
                        to restart Windows for your change to take effect.
                        Again, we typically recommend using a permanent Swap
                        file at least 4096k in size. A permanent swap file is
                        best because it gives the fastest access time, but a
                        Temporary Swap File doesn't use any hard drive space
                        when you are not using Windows. After you make the
                        swap file, you will be asked to restart Windows.
                        Choose restart then start your Windows program. For
                        further information on Swap Files, please consult your
                        Windows documentation.
                NOTE: You cannot use compressed disk space as a Swap file.
                If you use disk compression, you can only establish a Swap
                file on either the non-compressed host drive, or another
                non-compressed hard drive.  Creating or increasing the size
                of the swap file will take up hard drive space.

   IIc. Setting Up Your MIDI Mapper
                Since Sierra On-Line uses MIDI (Musical Instrument Digital
                Interface) music, in order to hear music in our games you
                must have your MIDI Mapper set up correctly. Normally, this
                is done when you install your sound card software, but many
                sound cards will default to an incorrect MIDI Setup.
                The instructions below are for setting up the MIDI Mapper for
                a standard FM sound card like a Soundblaster (Classic 8-bit,
                Pro and 16-bit varieties), Pro-Audio Spectrum, and other
                similar sound cards. These instructions will work for nearly
                all sound cards, though if you have a more advanced sound
                card like a Gravis Ultrasound, Sound cards using Wave table
                Synthesis, or a Roland MT32, RAP 10 or Sound Canvas, the set
                up instructions below will not provide the optimal MIDI
                configuration to take advantage of the advanced hardware.
                Please contact the hardware/sound card manufacturer if you
                need additional help configuring you MIDI Mapper for one of
                these more advanced sound modules.
        NOTE: When you install a Sierra Windows game, make sure you choose
        BASE level if you are prompted for a "Base" or "Extended".  The
        Extended setting is strictly for users with MIDI devices like the
        Roland MT32 installed in their systems.
                From within PROGRAM MANAGER:
                1.)     Double-click your MAIN group. 
                2.)     Double-click the CONTROL PANEL Icon.
                3.)     Double-click the MIDI MAPPER icon. NOTE: If you do
                        not have this icon, go back to the CONTROL PANEL, and
                        Double-click the DRIVERS section. Click on the "Add"
                        button, and in the list of drivers presented to you
                        highlight the MIDI MAPPER selection and click on OK.
                        After the driver is installed, you will need to
                        restart Windows and start at step 1 above.
                4.)     You will get a dialog box. Click on the NEW Button. 
                5.)     Type in a name (any name will do), then click on the
                        OK Button.
                6.)     Now you will get the MIDI SETUP screen. Find the Port
                        Name Column, and go down it until you reach the box
                        for channel 13. Click on the box, then click on the
                        arrow and you should get a list of drivers.
                7.)     Select the driver that has "FM Synthesis" in it. The
                        name may vary depending on the sound card you have,
                        but some examples are "Voyetra SuperSapi FM Driver",
                        "Yamaha OPL-3 FM Synthesizer", "SBP FM Synth".
                8.)     Repeat steps 7 and 8 for Channels 14, 15 and 16.
                9.)     Click on OK, and when the computer asks you if you
                        want to save the setting, choose yes.
                10.)    Close the MIDI MAPPER.
        Additional Note: Always make sure you have the proper Drivers
                installed for your sound card, as well as the following
                standard Windows drivers: Timer, MIDI Mapper, [mci] CD Audio,
                [mci] Sound, and [mci] MIDI Sequencer. If these are not
                present, you can add them following the steps below:
                        Again, from the CONTROL PANEL:
                        1.)     Double-click the DRIVERS icon.
                        2.)     You will get a list of drivers presented in a
                                dialog box. Click on the ADD button.
                        3.)     Select the driver you wish to add (Timer,
                                MIDI Mapper, [MCI] CD Audio, Sound, or MIDI
                                Sequencer)
                        4.)     Click on OK. If you are asked to use the
                                Current driver or a New one, click on Current.
                                You may be asked to insert a Windows disk to
                                install the driver from. Follow the
                                instructions on screen.
                        5.)     Once new drivers are installed, you will need
                                to re-start Windows. If you have any
                                difficulty installing the drivers, or need
                                additional help with Windows, please contact
                                Microsoft or your authorized hardware
                                manufacturer.
        Finally, it's usually a good idea to have the latest sound drivers
        available for your sound card. You can contact the Sound card
        manufacturer to obtain the most current drivers.

   IId. Sierra On-Line's Troubleshooting Steps:
        General Protection Faults
                General Protection Faults are Windows errors that are
                typically caused by a memory conflict between one or more
                drivers or programs.  Another type of error similar to a
                General Protection fault is a System Integrity Violation,
                caused by an MS-DOS program running Windows.
        NOTE: Sierra On-Line does not support running our DOS programs
        through Windows.  If a Sierra DOS program causes any error messages
        or a System Integrity Violation, we recommend that you run that
        program in DOS.

        Before You Start
                Before you begin troubleshooting General Protection Faults,
                you must have a basic boot disk for your system.  Boot disk
                instructions are available from FAX (document #2470).  A file
                called BDALL, which contains a boot disk creator utility and
                a complete set of boot disk instructions for a variety of
                systems, is also available. This file can be downloaded from
                our BBS at 206-644-0112, or you can contact us in Technical
                Support from FAX at 206-644-7697 or phone at 206-644-4343
                and have the disk sent to you.
        Finally, you will want a backup copy of your WIN.INI and SYSTEM.INI
        files on this disk. Copy them to the boot disk using the following
        commands:
                COPY C:\WINDOWS\WIN.INI A:      <ENTER>
                COPY C:\WINDOWS\SYSTEM.INI A:   <ENTER>
        (NOTE: If your Windows directory is on another drive, use the letter
        of that drive instead of C:.

        Troubleshooting Steps
                1.)     First, correct any and all FAT table errors and lost
                allocation units by running SCANDISK or CHKDSK.  Refer to
                Section I. General Troubleshooting Techniques for DOS and
                Windows programs, and read the instructions for Step 1 if
                you need additional information.
                2.)     Make sure your Windows System Resources are over 60
                percent. You can check this by going to the HELP menu in
                Program Manager, and choosing About Program Manager. If
                resources are below 60 percent, close any and all other
                Windows applications before continuing to the next step.
                3.)     Check the DOS version you are using. If you are using
                an OEM DOS version, such as IBM DOS or Compaq DOS, those
                should only be run on their respective OEM computer systems.
                (However, the Microsoft's DOS 5 and DOS 6 upgrades will work
                on all machines.)
                4.)     Run Windows in Standard Mode (Not available in Windows
                for Workgroups 3.11). You can run Windows in Standard mode by
                typing WIN /S and then pressing ENTER. If the GP fault occurs
                in Standard Mode and Enhanced Mode Windows, the problem could
                be a corrupted file or conflict between Windows and a
                hardware device.
                5.)     Run Windows without using your WIN.INI file. The best
                way to do this is to rename the WIN.INI file to something
                else. You can do this by going to DOS, then to your WINDOWS
                directory. Then type:
                        REN WIN.INI WIN.OLD     <ENTER>
                If running Windows without the WIN.INI file active corrects
                the problem, make sure the LOAD= and the RUN= lines in the
                [WINDOWS] section of the WIN.INI are blank, or insert a
                semi-colon (;) at the beginning of each line. (You can edit
                the WIN.INI with a text editor program like Windows Notepad.)
                This will prevent any other Windows software from loading. If
                this fails to correct the problem, Sierra On-Line recommends
                calling either MICROSOFT, or if you received your DOS/WINDOWS
                software with your computer system, you will need to contact
                the hardware manufacturer. They should be able to help you
                isolate the conflict between your WIN.INI file and your
                SIERRA program.
                6.)     Reinstall your Sierra Windows program, or the program
                that causes the GPF. Sometimes corrupted files and drivers
                (especially sound and/or video drivers in the case of Sierra
                On-Line Software) can cause GP faults, and re-installing them
                may correct the problem. Often times, updating to the latest
                available versions of these drivers will correct problems as
                well. Contact the software manufacturer if you need assistance
                re-installing and/or updating drivers.
                7.)     Eliminate any memory-resident software. Close any and
                all other applications, make sure the STARTUP group is empty,
                and disable any and all screen savers (including the standard
                Windows screen saver) and shell replacement programs like
                Norton Desktop for Windows, PC Tools, etc. Also, don't run
                Windows from a  menu program like DOS Shell or similar
                programs.
                8.)     To check for a Video driver conflict, change your
                Video driver to "VGA". A number of Video Drivers from third
                party vendors will conflict with some Sierra Windows
                programs.
                IMPORTANT NOTE: If your SIERRA ON-LINE program requires a
                256 color driver, use Microsoft's "SVGA" (640 by 480, 256
                color) driver if you have it available. If you do not have
                this driver available, use another driver for your video card
                and see if it makes a difference. You can contact Microsoft's
                BBS to obtain the driver from them.
                9.) Check for other possible conflicts with other,
                third-party software drivers. Edit your SYSTEM.INI file and
                temporarily comment out any and all third party drivers,
                e.g. Adobe Type Manager, third party printer drivers,
                Bitstream, etc. You can use Windows Notepad to edit the
                SYSTEM.INI file, and insert a semi-colon (;) at the beginning
                of each line that loads a third party driver. In your
                SYSTEM.INI file, the [BOOT] section should be set to a
                standard Windows default, which is listed below:
                        shell=progman.exe
                        system.drv=system.drv
                        keyboard.drv=keyboard.drv
                        mouse.drv=mouse.drv
                        display.drv=vga.drv      
                        comm.drv=comm.drv
                        sound.drv=mmsound.drv
                10.) Eliminate potential conflicts in DOS by creating a basic
                boot disk that loads only those drivers necessary to start
                your system and Windows. A minimum boot configuration is
                listed below:
                   AUTOEXEC.BAT                       CONFIG.SYS
                   __________________________         _________________________
                   Path=c:\;c:\DOS;c:\windows         Files=50
                   Prompt $p$g                        Buffers=30
                   Set temp=C:\                       Device=c:\DOS\himem.sys 
                   Stacks=9,256
                   Device=c:\windows\ifshlp.sys (WFW 3.11 ONLY)

                Depending on your particular systems, the files above may not
                be sufficient for your system to boot normally. If you need
                additional assistance creating a boot disk, see section I.6.

                If creating a boot disk corrects the problem, then your GP
                fault is caused by one of the memory resident DOS programs or
                Windows drivers that your system loads.
                This list is by no means exhaustive, but it does represent
                the most common solutions to General Protection Faults
                encountered with Sierra Windows Software. For additional
                assistance, you may wish to contact Microsoft or your
                Hardware dealer (if Windows came pre-installed on your
                computer).
III. General Sound Card Troubleshooting Steps
        Due to the tremendous number of sound cards and drivers available
        today, it can often be difficult getting a sound card and a game's
        sound driver to work together correctly.

        Sierra On-Line has composed the following list of Sound Card
        troubleshooting steps to help resolve the most common problems
        experienced configuring a sound card to work correctly with a game
        (and vice-versa). Please note that we cannot possibly know
        everything about your specific sound card, it's drivers, set up
        requirements, or the related software that is packaged with it.
        Therefore, if you have any questions as to how to change the
        settings, re configure, or otherwise manipulate your sound card,
        please refer to your sound card's documentation or consult your
        sound card's manufacturer.

        Sound Card-Common Symptoms
        1.)     Lockups. Often times a DOS or Windows program  will lock up
                the system if there is a sound card conflict. Often, the game
                will still appear to be playing normally -- you will be able
                to move the mouse, the background music will be playing, and
                you may even be able to access the Save/Restore functions.
                However, the mouse pointer will remain a "wait" cursor and
                all action in the game will effectively stop. Other times,
                even the mouse pointer will freeze (A "hard" lock up), and
                the sound card may become stuck on one continuous note.
                Occasionally this might even force the system to re-boot
                itself.
        2.)     No music and/or Sound effects. Sometimes you may hear music,
                but no speech or sound effects, or vice-versa.
        3.)     Distorted or garbled music or sound effects, possibly with
                crackling noises.
        4.)     Repeating or "broken record" type sound. Sometimes this will
                manifest itself in the form of one continuous, long musical
                note as well.
        5.)     DOS Error Messages:
                         "Unable to initialize your audio hardware" 
                         "Unable to initialize your music hardware"  
        6.)     WINDOWS Error Messages: 
                        "Wave Out Open Error"
                        "Panic: Use Capabilities Function..." 
                        "Sound Device already in use by another application".

Sound Card Troubleshooting Steps
	(DOS\WINDOWS): First and foremost, make sure you choose the
                        appropriate sound drivers or sound choices when you
                        install the game !  Don't always trust the default
                        values, because sometimes installation programs will
                        incorrectly detect your hardware.  For example, if
                        you have a standard Soundblaster, Soundblaster Pro or
                        Soundblaster 16,  and the game's installation program
                        detects "Roland MT32", this isn't going to work.
                        Sometimes choosing the correct driver can be tricky,
                        but for most sound cards, selecting
                        "Soundblaster/Ad-lib" for the music selection and
                        "Soundblaster" for the Audio/Speech  selection (if
                        there is an Audio/Speech selection -- not all games
                        will have one) is the best place to start if you do
                        not see a driver listed for your specific sound card.
                        If you experience problems with these selections, use
                        some of the others -- it can't hurt. For Windows
                        programs, if you are given a choice of selecting
                        "Base" or "Extended", start with Base level.

	(DOS/WINDOWS): Check the DMA and IRQ settings for your sound card.
                        Generally speaking, we recommend using DMA 1 and IRQ 5,
                        I/O address 220 for best results. However, as a general
                        rule, our DOS games will support DMA channels 1 and 3,
                        and IRQ settings of 3, 5 and 7. If you are experiencing
                        any of the previously mentioned problems, change the
                        DMA and/or IRQ setting for your sound card and see if
                        that works. Use our recommended settings if possible.

	(DOS/WINDOWS): If you are not hearing any music or sound, try the
                        steps above.  You should also run the mixer program
                        for your sound card and turn up the music and sound
                        effects volume levels. If you are having the problem
                        under DOS, run the DOS-based mixer, if the problem is
                        under Windows, run the Windows-based mixer program.
                        Sometimes not hearing music or sound effects is just
                        due to the volume levels that the sound card is set
                        to.
	(DOS/WINDOWS): Running DOS-based games in Windows generally will not
                        work.  Symptoms include repeating sounds, no sound or
                        music, or other error messages like "DMA Buffer Size
                        is Too Small....".  For best results, we recommend
                        running DOS-based games in DOS.

	(DOS): Try new drivers ! For DOS-based games, it never hurts to check
                        with Sierra On-Line Technical Support, CompuServe, AOL
                        or our BBS to see if there are any updated sound
                        drivers for some games. We can mail these drivers out
                        free of charge.
	(WINDOWS) Make sure the MIDI Mapper is set up correctly. For a
                        complete set of instructions on setting up the MIDI
                        Mapper for standard sound cards, refer back to
                        SECTION IIC: Setting Up Your MIDI Mapper.

	(WINDOWS): Always make sure you have the proper Drivers installed for
                        your sound card, as well as the following standard
                        Windows drivers: Timer, MIDI Mapper, [mci] CD Audio,
                        [mci] Sound, and [mci] MIDI Sequencer. Also, it's
                        usually a good idea to have the latest sound drivers
                        available for your sound card. You can contact the
                        sound card manufacturer to obtain the most current
                        drivers. If you need help installing any of these,
                        please refer to SECTION IIC: Setting Up Your MIDI
                        Mapper.

	(WINDOWS): Some Windows sound enhancement programs or screen savers
                        can conflict with games if they are running at the
                        same time. Often, they produce error messages like
                        "Wave Out Open Error" or "Panic: Use Capabilities
                        Function...". Some examples of programs that can
                        produce these types of errors are "Afterdark",
                        "Wired for Sound", "Icon Hear-it" or "Icon Do-it",
                        and "Microsoft Windows Sound Bits."
