MS-DOS PROMPT OF WINDOWS 95 SECTION 9 - PERFORMANCE TIPS SECTION 10 - IF YOU STILL HAVE PROBLEMS... NOTE*** If distorted video and/or audio is encountered, please verify that your sound card is 100% Sound Blaster 16 compatible. The main reason behind most video and/or audio distortion is due to 8 bit sound cards (e.g. Sound Blaster Pro compatible). SECTION 1 - HARDWARE REQUIREMENTS FOR MS-DOS VERSION - 100% IBM PC-compatible computer - Processor Type: Pentium - 16 MB RAM - 35MB of uncompressed hard disk space - 256 Color (640 x 480) VESA local bus or PCI video card with 1 MB RAM - VESA local bus or PCI video with 1 MB RAM - Microsoft MS-DOS 6.22 operating system with MSCDEX 2.10. - 100% Sound Blaster 16 compatible sound card - Quad-speed CD-ROM drive (600K/second sustained transfer rate) - 100% Microsoft-compatible mouse and driver - Dedicated game card is highly recommended for joystick Please Note: In order to play Twinsen's Odyssey for MS-DOS(r) the CD must be in your CD-ROM drive at all times. Twinsen's Odyssey may have trouble working with some 1993 or earlier Matsushita CD-ROM drives. These CD-ROM drives have trouble reading beyond 63 minutes on CDs, and Twinsen's Odyssey uses the full CD. These drives were sold under the names of Panasonic, JVC, Reveal, Creative Labs and Plextor. Game play may occasionally slow down and the CD-ROM drive will be accessed constantly. We highly recommend that you upgrade to a newer CD-ROM drive to avoid problems with other programs in the future. SECTION 2 - ABOUT THE MS-DOS VERSION - Highly recommended that the game be played from MS-DOS MODE or DOS 6.22. The MS-DOS Prompt of Windows(r) 95 is not recommended. - Does not use Microsoft DirectX video and audio drivers. - Should not be installed to a compressed drive. SECTION 3 - INSTALLATION PROCEDURES A. ----------MS-DOS 6.22---------- (1) At the DOS prompt, type D: and press Enter. (for these instructions, we will assume that your CD drive is D:). (2) At the D: prompt, type CD\DOS and press Enter. (3) At the D:\DOS> prompt, type INSTALL and press Enter. (4) Follow the on-screen instructions carefully. (5) When installation is complete, you will be returned to the directory in which Twinsen's Odyssey was installed. To begin your Twinsen's Odyssey experience, type TWINSEN and press Enter. B. ----------MS-DOS MODE---------- (1) Make sure the CD is in the CD-ROM drive. (2) If the Twinsen's Odyssey title screen is displayed, click the Exit button. (3) Click on the Windows 95 Start button, choose shutdown. (4) Now click on the option SHUT DOWN AND RESTART IN MS-DOS MODE, then choose OK. (5) At the DOS prompt, type D: and press Enter. (for these instructions, we will assume that your CD drive is D:). (6) At the D: prompt, type CD\DOS and press Enter. (7) At the D:\DOS> prompt, type INSTALL and press Enter. (8) Follow the on-screen instructions carefully. (9) When installation is complete, you will be returned to the directory in which Twinsen's Odyssey was installed. To begin your Twinsen's Odyssey experience, type TWINSEN and press Enter. C. ----------MS-DOS PROMPT OF WINDOWS 95---------- Although we do not recommend it, the following will work on some machines. (1) Make sure the game's CD is in the CD-ROM drive. (2) If the Twinsen's Odyssey title screen is displayed, click the Exit button. (3) Close all open windows on your screen. You can close a window by clicking on the close button located in the top right-hand corner of the window. Also close programs listed on the Taskbar. Do this by right-clicking on a program's button and selecting Close. (4) Double-click on the My Computer icon located on the desktop. (The name of this icon may have been changed by you or the person who installed Windows 95 on your system.) In the window that opens, right-click on the icon for your CD-ROM drive and select Open. Look for the Install icon in the DOS folder. (The icon is a picture of a window labeled Install underneath it.) Double-click on this icon to start the Twinsen's Odyssey MS-DOS Installer and follow the on-screen instructions. Important: Note that a message will appear at the end of the install process that asks if you want to make a boot disk. Answer No. The game's Boot Disk-maker utility was designed for systems using MS-DOS as their operating system and will not work properly with Windows 95. (5) After installation is complete, if the DOS box is still on the screen, close it by clicking on the close button located in the top right-hand corner of the DOS box window. (6) Double-click on the My Computer icon. In the window that opens, double-click on the icon for the hard disk drive where Twinsen's Odyssey was installed. Look for the Twinsen folder icon. (The icon is a picture of a folder labeled Twinsen underneath it.) Double-click on this icon to open the folder; look for the DOS icon labeled TWINSEN and double click on it to start the game. If the above process does not work for you, click on the Start icon, choose Shutdown and restart the computer in MS-DOS mode. At the MS-DOS prompt, go to the directory where you installed Twinsen's Odyssey (default is \TWINSEN), and from the TWINSEN directory type TWINSEN and press Enter to start the game. NOTE: If your system came pre-installed with Windows 95, you may not have the necessary MS-DOS drivers for your mouse, CD-ROM and sound card to play the game. Please contact your system manufacturer for these DOS drivers. SECTION 4 - COMMON SETUP AND INSTALLATION PROBLEMS A. ----------SOUND---------- In order to enjoy the audio component of the game, you will need to select your sound device for digital audio. Choose your sound card from the list provided. The Installer will then try to verify the presence of that sound card in your system. If your sound card is not shown and is 100-percent Sound Blaster 16 compatible, you should be able to select the Creative Labs Sound Blaster 16 driver to hear sound and music in the game. When you are finished selecting the proper sound devices, select DONE and press . If you need to set the sound card manully here are a couple of methods to try and find out what sound card you have and what the proper Port, IRQ and DMA settings are for your computer: View your CONFIG.SYS and AUTOEXEC.BAT files which are found at the root directory of your hard drive. Look at the lines that load the set parameters of your sound card for clues to what the I/O Port, IRQ and DMA settings should be set to. Also, for more clues type SET at a MS-DOS prompt and press Enter. Look at the BLASTER = line. Record that information and use it to manually detect your sound card. B. ----------POST INSTALLATION NOTES---------- After installing Twinsen's Odyssey, it is easy to change your sound device configurations, or make a Boot Disk (if you bypassed these steps while installing). Simply go to the Twinsen's Odyssey directory on your hard drive, type SETUP and press Enter. This will launch a program that will allow you to do all of these options. SECTION 5 - BEFORE RUNNING Twinsen's Odyssey When playing the MS-DOS version of Twinsen's Odyssey, we strongly recommend that you run under the following conditions: Before playing, close all other applications. Some users have experienced random fatal errors while playing Twinsen's Odyssey if they have other memory-intensive programs running at the same time. We highly recommend running Twinsen's Odyssey as a stand-alone DOS application. Do NOT play the MS-DOS version of Twinsen's Odyssey through Windows 3.1x. Completely exit out of Windows and start the game from the MS-DOS prompt. SECTION 6 - TROUBLESHOOTING STEPS A. ----------MEMORY---------- Twinsen's Odyssey requires a minimum of 8 MB of main memory (RAM). On some machines, even if you have the required 8 MB of RAM, Twinsen's Odyssey may report that you do not have enough free extended or conventional memory. During game start up, Twinsen's Odyssey will determine if there is enough free memory to properly run. If it is determined that there is not enough memory available, then the program will let you know how much additional memory is needed. In many cases you may be able to remove/disable only one or two TSRs (Terminate and Stay Resident programs) or drivers that are not needed to run Twinsen's Odyssey, to make this memory available. You might also try disabling SMARTDRV, changing your CONFIG.SYS and AUTOEXEC.BAT so that some of your drivers are loaded into conventional rather than high memory or setting your EMM386 line to NOEMS. Since these modifications affect your CONFIG.SYS and AUTOEXEC.BAT files, you should consider making these changes to CONFIG.SYS and AUTOEXEC.BAT files on a boot disk. See the section on creating a boot disk for more details. B. ----------VIDEO---------- Twinsen's Odyssey was designed to take advantage of some of the higher resolution video modes on your computer. In most cases Twinsen's Odyssey will detect and work with your video card just fine. However, some video cards may require that a VESA video driver be loaded in order for the video card to work properly with Twinsen's Odyssey. VESA stands for Video Electronics Standards Association. It is a standard that allows software companies to write programs that work on many video cards without having to know how each card works. The VESA driver is the program that handles this. Almost every video card available today has VESA drivers available for it. These drivers may be stored in a BIOS chip on the video card, or they may be a program that the user has to load by hand (or with a batch file). Some cards (such as the Diamond Viper) have the driver on the video card, but need the user to run a special program to activate the driver. If the VESA driver is an external program, it will probably be found on the disks that came with your video card. If you don't have a VESA driver you should contact your video card manufacturer. If the VESA driver supplied by your video card does not function properly with Twinsen's Odyssey, try using the Display Doctor utility. This is available for downloading from the SciTech Software Web page (http://www.scitechsoft.com). It might also be located on your local BBS or other online services. ***Question*** I am having troubles making my video card support VBE 2.0. How do I make my card support this mode? ***Answer*** Twinsen's Odyssey was designed to take advantage of the higher resolution video modes on your computer. In most cases, Twinsen's Odyssey will detect and work with your video card just fine. However, some video cards may require that a VESA video driver be loaded in order for the video card to work properly with Twinsen's Odyssey. Twinsen's Odyssey for MS-DOS requires that your video card can support the VBE 2.0 standard, as set forth by VESA. Please verify that you have this VESA video driver for your video card loaded before launching Twinsen's Odyssey for MS-DOS. ***Question*** I have a Trident video card and I can't get the game to start correctly ***Answer*** We suggest you try playing in MS-DOS Mode. Please follow these instructions: (1) There is a file named TRIVESA.EXE on our web site. It contains updated video drivers which are required for the game to play. (WWW.ACTIVISION.COM) (2) After TRIVESA has been downloaded exit to DOS MODE. (3) Type TRIVESA, from wherever it was downloaded to. If you do not know where it is, go to DOS Mode type CD\ and press , then type DIR TRIVESA.* /s , and press . (4) Follow the instructions that appear after typing TRIVESA. If after installing Trivesa you still have problems, please contact Trident at 415-691-9211. ***Question*** I can not seem to get my ATI video card to support VBE 2.0. What should I do? ***Answer*** If you are unable to play in either the Windows 95 or DOS modes, please contact ATI at (905) 882-2626. The ATI cards have many different BIOS versions. Each BIOS version does something a little different. Ex. Some support VESA 2.0, some just 1.2. Some older drivers work with WIN95 for our games, while other newer ones may not depending on the BIOS. Using a program they supply, ATI can help find your cards specific part number. ATI Customer Support can then use your part number to find your cards BIOS. After the correct BIOS is determined ATI can determine the cards features and help trouble shoot your video problems. C. ----------SOUND---------- In the PC environment, sound card detection and configuration is often a difficult process. Although many cards can be automatically detected and configured, there are cases where this is not true. It is often necessary to use a manual card selection (select a card manufacturer and model) and configuration.(select I/O, DMA and IRQ). Because of the complexity of some sound cards, it may be necessary to try several options. ON SYSTEMS WITH A SCSI DISK CONTROLLER, YOU SHOULD SKIP THE AUTODETECTION ALTOGETHER. You should always use the Test option to verify that a valid configuration was selected. It is often possible to determine the resources needed by your sound card (resources include I/O address, DMA channel, and IRQ interrupt number), either from your AUTOEXEC.BAT file (if in DOS), or from the SYSTEM utility (if in Windows 95). To run the SYSTEM utility from Windows 95, select Start, Settings, Control Panel, then select the System icon. When in the SYSTEM utility, select the Device Manager tab, then select the "Sound, Video and Game Controllers", select your sound card, and the Resources tab to see the settings for your sound card. A typical entry in the CONFIG.SYS file would be as follows: SET BLASTER=A220 I5 D1 H5 T6 This indicates I/O port 220, IRQ 5, and 5 for high DMA (i.e.16-bit sound). Whenever possible use high DMA. Many software configurable sound cards require that a separate utility is run, before the card can be used. For example Sound Blaster 16 requires that the card is configured using the SB16SET utility. Please refer to your sound card manual for the method used for your card. IF YOU DO NOT CONFIGURE YOUR SOUND CARD CORRECTLY, YOU MAY EXPERIENCE DMA OR IRQ CONFLICTS WITH OTHER CONTROLLERS (E.G. NETWORK CARDS WILL FAIL). ***Question*** My Program runs under MS-DOS 6.22 or MS-DOS Mode 7.0 but not under a Windows 95 DOS Prompt. ***Answer*** The DMA used for your sound card for MS-DOS and MS-DOS Prompt and/or MS-DOS Mode may be different. You may have to reconfigure the sound card settings, by typing SETSOUND from wherever you installed Twinsen's Odyssey to (e.g. C:\TWINSEN). This should be done from where the game will most likely be played from. ***Question*** My sound cards worked fine before I ran the Twinsen's Odyssey SetSound utility. Now they do not work. ***Answer*** On systems with two sound cards, it is not always possible to detect both cards at the same time. Within the SETUP utility you should configure your sound card using the manual mode (do not use Auto Detect). ***Question*** My sound card plays sounds but the WAVE files sound awful. ***Answer*** Most sound cards offer Sound Blaster emulation, but sound much better if used in their native mode. Use manual selection in SETUP, and make sure that the native mode is selected. It is also important that all cards (including the Sound Blaster) are set for 16-bit sound. In many cases the card uses two DMA channels, one for 8-bit operation and one for 16-bit operation. This can also be a problem. ***Question*** I am using arrow keys to select the sound card and arrow keys to select the resources, but the card still does not work. ***Answer*** You must press enter after you highlight the sound card name. Only after that can you select resources for that card. ***Question*** On my Compaq machine the SETUP auto detects the card as Sound Blaster, but I know that it is not correct. ***Answer*** Try to manually select ESS AudioDrive. ***Question*** I have an IBM Aptiva with a MWAVE card (i.e. sound/modem card). I am getting choppy sound and video. What should I do? ***Answer*** If distorted video and/or audio is encountered, please verify that your sound card is 100% Sound Blaster 16 compatible. The main reason behind most video and/or audio distortion is due to 8 bit sound cards (e.g. MWAVE sound cards). You can still try the following, but a 100% Sound Blaster 16 compatible sound card is required. Please follow these instructions EACH TIME before playing Twinsen's Odyssey: (1) From WIN95, click on the START button and chose shutdown. (2) Select Restart the computer in MS-DOS Mode? (3) Choose the OK button (4) Type MWGAMES ON and press . (5) Next, type CD\TWINSEN and press (6) Type TWINSEN and press If the game has no volume or it is to low you will want to use the mixer utility provided by IBM. Please follow the instructions listed below for volume control settings. (1) From a DOS Mode prompt type CD\MWD\MANAGER and press . (2) Type MWVOLUME and press These will be your options: Hold down CTRL, ALT, U. Hold all three of these buttons down at the same time for about 5 seconds. This will turn up your sound. Hold down CTRL, ALT, D. Hold all three of these buttons down at the same time for about 5 seconds. This will turn down your sound. Hold down CTRL, ALT, F. Hold all three of these buttons down at the same and it will turn on FM Mode. Hold down CTRL, ALT, W. Hold all three of these buttons down at the same and it will turn on WAVE Mode. Once you are finished choosing your settings in the volume control area follow the next 2 steps. (1) Type CD\TWINSEN and press (2) Type TWINSEN and press If problems persist you might want to consider contacting IBM at: Technical Support: (404) 238-1234 Technical Support Multimedia: (908) 329-7131 Technical Support PS/1 PRO: (800) 765-4747 Technical Support Valuepoint: (800) 772-2227 Technical Support Valuepoint: (213) 621-5576 BBS: (919) 517-0001 World Wide Web: http://vm.cfsan.fda.gov/ibmlist.html ***Question*** I have a Packard Bell and have no sound when playing the MS-DOS version of Twinsen's Odyssey. What should I do? ***Answer*** If distorted video and/or audio is encountered, please verify that your sound card is 100% Sound Blaster 16 compatible. The main reason behind most video and/or audio distortion is due to 8 bit sound cards (e.g. Aztech, Sound144, Sound16A, and Forte16 sound cards). You can still try the following, but a 100% Sound Blaster 16 compatible sound card is required. Please use the mixer utility provided by Packard Bell. Follow the instructions listed below for volume control settings. (1) From DOS Mode prompt type CD\SOUND144\UTILITY and press . SOUND144 can be replaced with FORTE16 or SOUND16A depending on the sound card you have. (2) Type MIXTSR and press (3) Hold down the ALT key while you press the / key. (This will activate a menu.) These will be your options: TAB = Moves your selection choice to the next device to manage. Right arrow = Turns the volumes up. Left arrow = Turns the volumes down. S = Save E = Exit Once you are finished choosing your settings in the volume control area follow the next 2 steps. (1) Type CD\TWINSEN and press (2) Type TWINSEN and press D. ----------MOUSE---------- ***Question*** Why do I get an Error: "Mouse Not Found" message? ***Answer*** This message is usually the result of one of two problems. First, and most likely, a mouse driver has not been loaded. Twinsen's Odyssey DOS needs a DOS mouse driver to run in MS-DOS mode. You can try playing in a Windows 95 DOS box or load your DOS mouse driver to play in MS-DOS mode. To exit Windows 95 to MS-DOS mode and load your MS-DOS mouse driver follow these instructions: (1) Click on the START button. (2) Choose Shut Down. (3) Choose the Restart the computer in MS-DOS mode option. (4) Now click on the YES button. Find the mouse driver executable. After it is found execute it by typing its name (e.g. C:\MOUSE.EXE). If you are unaware of where it is follow these instructions: (1) Type CD\ and press (2) Type DIR *MOUSE.* /S and press This will show you what directory your mouse resides in (e.g. C:\MOUSE). As the example states MOUSE being the directory it is in, you would then type CD MOUSE. This will put you in the mouse directory where you can then type its name. The name may be LMOUSE, MOUSE, MSMOUSE. Those names will be displayed when you follow the steps stated above on how to find your mouse. If your mouse driver is not found you will want to contact your system, or mouse manufacturer for a updated DOS mouse driver. Another reason you would get this error is that the mouse driver is being correctly loaded, but it is an older version that is not supported. In this case you should contact your system, or mouse manufacturer for the updated DOS mouse driver as well. SECTION 7 - CREATING A BOOT DISK A. ----------STANDARD BOOT DISK--------- If you experience problems playing Twinsen's Odyssey or receive messages telling that you do not have enough memory to play. You will probably need to create a Boot Disk. A Boot Disk lets your machine boot from a floppy disk and will not load memory-extensive programs, freeing more memory up for Twinsen's Odyssey. We have included an option that will automatically create a Boot Disk for you in this package. To create a Boot Disk, first go to the \TWINSEN directory. For example, if you installed Twinsen's Odyssey to C:\TWINSEN, you would type CD\TWINSEN and press Enter. Then type SETUP and press Enter. Select Make a Boot Disk. Follow the on-screen prompts, and the program will create a Boot Disk for you. If you still lack sufficient memory, please refer to the next section, on making a advanced boot disk. B. ----------ADVANCED BOOT DISK---------- Sometimes even a Boot Disk creator can't get you past the memory limit required to run a program. In the event you find our automatic Boot Disk creator doesn't do the job, we have provided the following sample CONFIG.SYS and AUTOEXEC.BAT files to assist you in getting Twinsen's Odyssey up and running. If you are creating a Boot Disk from scratch, start with Step 1. If you have already used the automatic Boot Disk creation utility in the Twinsen's Odyssey installer, start with Step 3. Step 1: Place a diskette in your A: drive. The next step will erase any data on the disk, so a new, blank floppy disk should be used. Make sure that the disk is the same density as the drive (use a 1.44 MB disk in a High Density 3.5" drive, etc.). Step 2: At the C: prompt, type FORMAT A: /S and press Enter. The DOS Format utility will format the disk and add the necessary DOS files required to boot from the floppy disk. Step 3: Change to drive A by typing A: and pressing Enter. Then type EDIT CONFIG.SYS and press Enter. The DOS Editor program will appear. If you used our Boot Disk-maker, just make sure the following lines, or similar lines, in the [CONFIG.SYS] example on the next page, are in your CONFIG.SYS file. Type REM and a space in front of all other lines not listed. If you are making your own Boot Disk manually, then type in the lines following [CONFIG.SYS] in the example below. When you are finished typing the lines, press ALT-F to bring up the File menu, and then type X to Exit the DOS Editor program. When it asks you if you want to save your file, choose Yes. [CONFIG.SYS] DEVICE=C:\DOS\HIMEM. SYS DEVICE=C:\DOS\EMM386.EXE NOEMS DOS=HIGH,UMB FILES=40 BUFFERS=15,0 STACKS=9,256 Insert your CD-ROM driver line here In the CONFIG.SYS file shown above, replace the last line in the example with the line from your current CONFIG.SYS file on drive C: that runs your CD-ROM drivers. It is important that you use your CD-ROM line and not our example, otherwise your CD-ROM drive will not function properly. Additionally, if your graphics card requires a VESA driver, it should go here as well. Step 4: Type EDIT AUTOEXEC.BAT and press Enter. The DOS Editor program will appear. If you used our Boot Disk-maker, then just make sure these lines, are similar to the lines, in the [AUTOEXEC.BAT] example below. Type REM and a space in front of all other lines not listed. If you are making your own Boot Disk manually, then type in the lines, like the [AUTOEXEC.BAT] example below. When you are finished typing the lines, press ALT-F to bring up the File menu, and then type X to exit the DOS Edit program. When it asks you if you want to save your file, choose Yes. [AUTOEXEC.BAT] @ECHO OFF PROMPT $P$G Insert your PATH statement here LH C:\DOS\MSCDEX.EXE /D:MSCD000 SET SOUND=C:\SB 16 SET BLASTER=A220 15 D1 H5 P330 T6 C:\SB I6\DIAGNOSE /S C:\SB 16SET /P /Q SETMIDI=SYNTH:I MAP:E C:\MOUSE\MOUSE.EXE CD\TWINSEN TWINSEN In the AUTOEXEC.BAT file shown above, you would replace the third line with the SET PATH command from your current AUTOEXEC.BAT file on drive C:. Replace the fourth line with the line from your current AUTOEXEC.BAT file on drive C: that loads MSCDEX.EXE. It is important that you use your CD-ROM line and not our example, otherwise your CD-ROM drive will not function properly. You may also have special lines in your C:\AUTOEXEC.BAT file that help your sound card to function properly. It is very important that you copy those lines into this new file on A: so your sound card can work. Replace the examples on lines 5 through 9 with the appropriate lines from your AUTOEXEC.BAT file. If you do not know which line from your current AUTOEXEC.BAT runs your CD-ROM drivers, or which lines are for your sound card, you should contact the hardware manufacturer of the item in question. Line 10 which loads your mouse driver is only an example. The command to load your mouse driver is most likely different than our example. Replace line 10 with the command that loads your mouse driver. Step 5: Leave the disk in the drive and reboot your system. The game should start and everything should be working properly. NOTE: Some systems require special steps in order to boot from a floppy disk. If you are not in the Twinsen's Odyssey directory after attempting to boot from the floppy, contact the system manufacturer to learn what steps must be taken to start from a boot disk. SECTION 8 - THREE WAYS TO PLAY FROM A MS-DOS PROMPT The DOS version of Twinsen's Odyssey can only run from a DOS prompt. With today's PC compatible systems, there are three ways to get to the DOS prompt: A. ----------MS-DOS 6.22---------- Booting into DOS 6.22 (also called by Windows 95 "Previous version of MS-DOS" ). This is the preferred method to run Twinsen's Odyssey, and it is the only way on a system without Windows 95. On systems with Windows 95 you may be able to select this mode, during booting process, by pressing the F8 key. Depending on the method used to install Windows 95, this option may not be available. Advantage: Avoids potential conflicts between Windows 95 display & sound drivers and the DOS drivers used by the Twinsen's Odyssey game. SETUP works reliably. Disadvantage: On systems with Windows 95, your 16-bit CD-ROM and Mouse drivers may not be installed (CONFIG.SYS and AUTOEXEC.BAT files may have to be updated). B. ---------MS-DOS MODE---------- Boot into DOS 7.0, by clicking the START button, then choosing SHUTDOWN. Now choose RESTART THE COMPUTER IN MS-DOS MODE. Advantage: Avoids potential conflicts between Windows 95 display & sound drivers and the DOS drivers used by the Twinsen's Odyssey game. SETUP works reliably. Disadvantage: On systems with Windows 95, your "old style DOS" CD-ROM and Mouse drivers may not be installed, and you may have to find and load 16-bit drivers in order to be able to access the CD-ROM drive, or the mouse. C. ----------MS-DOS PROMPT OF WINDOWS 95---------- To use the MS-DOS prompt of Windows 95, click the START button, then choose PROGRAMS. Now choose MS-DOS Prompt. Advantage: Guarantees that the CD-ROM driver and the Mouse driver are available (without a need to load older 16-bit drivers). The Virtual Memory available to Windows can also be used by the game (this improves performance of the game on machines with more than 8 MB of RAM). Disadvantage: It is often impossible to do automatic sound card detection, since Windows intercepts all of the I/O and IRQ requests, and returns unpredictable results to the auto-detection software. Even after manual setup, there is a potential for DMA or IRQ conflicts between the resources allocated by the Windows 95 Resource Manager, and the resources detected by the DOS setup program. On some systems (we have seen this on an HP machine) the VESA BIOS calls are not supported in the DOS Box (i.e. They are supported in MS-DOS MODE). SECTION 9 - PERFORMANCE TIPS Make sure that your sound card is configured for 16-bit stereo sound. All of the game sounds are stored as 16-bit wave files. Playing these wave files on 8-bit cards will require time consuming conversion, resulting in choppy movies, and poor sound quality. SECTION 10 - IF YOU STILL HAVE PROBLEMS...
