1. SUPPORT
IBM Bulletin Board (PCC BBS)
Driver upgrades including WIN-OS/2, when available, can be obtained
through the IBM Personal Computer Company Bulletin Board System.
The phone number for this system is (919) 517-0001.
Please note that upgrades may come in different forms such as patches to the
main software or a whole new software package. Therefore, we suggest you back
up your software before you attempt to update.
2. INSTALLATION
2.1 SWITCH AND JUMPER SELECTIONS
* You must ensure that the ALL jumper settings on your DSP modem match
the settings specified on the DSP modem configuration screen when
running the verification program. If the settings do not agree, your
system may hang (lock up) when you execute the basic or advanced tests.
Furthermore the card will not function.
2.2 INSTALLATION OF DRIVERS
* Refer to the user's guide 'Quick Installation' and follow the
promptings of the install program. Since the DSP Modem has
undergone several improvements to it's functions, and since
there are numerous upgrades to follow, the user's guide detailed
installation procedure is out of date. Please ignore 'Installing
the DSP Modem Support Drivers' chapter under 'DSP Modem Support
Drivers', instead follow the promptings of the install program.
NOTE: This applies to older 'IBM V.32bis DSP Data/Fax Modem'
user's guide only.
* Uninstall (remove) ALL drivers prior to doing a selective install.
You MUST remove ALL drivers and run install if the switches or
jumpers on the card have changed. Unistall, of course, is done
by choosing the unistall option presented when the setup program
is run from diskette1 of the 3 diskette installation set. While
in setup, please ensure that the settings presented by the
install program match that of the card. This will ensure that the
factory defaults (the actual settings) correspond to what is
published in the user's guide.
* Be sure to store your personal files in your own directory; For
instance C:\MY_MWW. The setup program removes ALL files and
directories while removing (uninstalling) the DSP modem drivers!
* The install program removes all drivers from memory prior to entering
the install menu. If the user should choose to CANCEL during
installation, then be sure to exit and reenter Windows(tm) so as to
install the drivers in memory.
2.3 COMPATIBILITY
* Compatibility testing has revealed the following information relative
to the DSP modem's proper operation in these systems, or with these
system configurations:
Tandy 2500 SX
The I/O Ready jumper (J5), must be set to the Alternate position.
IBM PS/ValuePoint P60/D
The DMA level setting jumpers (J1,J2) must be set to level 0.
Communications port COM4, the factory default setting for the DSP
card, may have to be changed. Try using COM1, COM2, or COM3.
* Testing has revealed that when the DSP modem is used in a PC that has a
local bus graphics accelerator card that uses an ATI processor, system
hangs sometimes occur.
This is due to the ATI processor's interaction with system memory
refresh. ATI has been made aware of this condition.
When this condition occurs, your only recourse is to turn your system
power OFF and ON (or press the system RESET switch if you have one) to
restart your system.
* Testing has revealed that when the DSP modem is used in a PC that has a
fixed disk connected to a SCSI adapter using the base address 0330h to
0335h, the system is unable to recognize the hard disk during boot up.
* Testing has revealed that several PC utilities have not been able to
report the DSP modem in the system. These are DOS utilities that are
not checking hardware installed for Windows. We have informed most of
these companies.
3. MODEM INFORMATION
* When setting up a communications application to work with the DSP
modem, you should set the modem type as one of the following:
IBM modem, or
ACE modem, or
Hayes modem, or
Hayes compatible modem, or
Hayes 2400B, or
Hayes Smartmodem 2400, or
other (here you will have to include your own AT
command initialization string.)
* The semicolon dial modifier (for the AT D command) must be the last
character in the command string. Any commands between the semicolon and
the Carriage Return will be ignored.
Example:
ATDT1234567,,,,33333,,,,;H<CR> (The H will be ignored).
To accomplish the same function as the example, do the following:
ATDT1234567,,,,33333,,,,;<CR>
ATH <CR>
* Modem compatibility testing has revealed the need for the following
helpful tips for using your DSP modem: Note: References below to
Mwave Modem refer to the programs in your DSP Modem group that should
be running in Windows. You should see either a visual image of a
modem on your screen, or a minimized version of the same. The large
version of the modem will have several "lights" with names like "FS",
"AA", "RD", "TD", and "CD". The minimized version of the modem will
not have the names, but will show the "lights".
A) Scenario: Mwave Modem 9600 (V.32) fails to connect at 2400 bps or lower
speed modem.
Tip: It is difficult for V.32 (9600 bps) modems to handshake and get
connections with a few older 2400 bps or slower modems. If the
Mwave Modem 9600 is not connecting with a 2400 bps modem, try
setting the DSP modem to negotiate at 2400 bps or below. There
are several ways to do this:
Option 1. Set S28=9 for maximum connect rate of 2400 bps or,
Set S28=8 for maximum connect rate of 1200 bps or,
Set S28=6 for maximum connect rate of 300 bps.
The Com Port can be set to any rate at or above the
connect rate in this case.
Option 2. With S28=0, set the COM Port speed to 2400 bps for
maximum connect rate of 2400 bps or,
With S28=0, set the COM Port speed to 1200 bps for
maximum connect rate of 1200 bps or,
With S28=0, set the COM Port speed to 300 bps for
maximum connect rate of 300 bps.
Option 3. Load the Mwave Modem 2400 instead of the Mwave Modem
9600. The COM Port can be set to any rate at or
above the connect rate.
If the connection still fails, try option 3 with
option 1; if it still fails, then try option 3 in
combination with option 2.
B) Scenario: DSP modem does not connect to a 300 bps or below modem.
Tips: 1. Set the DSP modem for Bell 103 or CCITT V.21 mode to match
the other 300 bps modem.This is done with the ATBn command
(where n=0)
2. Set S28=6 for connect rate of 300 bps or,
Set S28=5 for connect rate of 150 bps or,
Set S28=4 for connect rate of 134.5 bps or,
Set S28=3 for connect rate of 110 bps or,
Set S28=2 for connect rate of 75 bps or,
Set S28=1 for connect rate of 50 bps.
3. We recommend you disable MNP features for 300 bps or below
since most modems do not support MNP features at these
rates. You can disable MNP with the AT\N0 command.
C) Scenario: Mwave Modem 2400 calls a bulletin board line that supports
9600 bps or above and they fail to complete the connection.
Tip: 1. Many bulletin boards that charge extra for 9600 bps or above
service will only connect at the supported rate. This
prevents accidental charging for the high speed line when a
connection is negotiated to a lower speed. For services
with this restriction (for example, Prodigy and CompuServe),
the DSP modem must be used to call the 9600 bps bulletin
board.
There should be no such difficulty when calling a 2400 bps
bulletin board with the Mwave Modem 9600.
D) Scenario: Using DOS communication application to drive the DSP
modem, and the receive data appears to get dropped when
being output to the screen.
Tip: 1. Refer to the Windows SYSINI.WRI help file in the \WINDOWS
directory for COM settings in the SYSTEM.INI file. For DOS
applications and 16550 UART support, Windows recommends
disabling ComxBuffers (ex: Com2Buffers=0). NOTE: Use this
for DOS communications applications only.
E) Scenario: My modem locks up when I use it with multiple Windows
applications.
Tip: You should make sure to install your DSP Modem as the first
available COM port. If your system does not currently have
a COM1 port, you should install the DSP Modem as COM1. If
you already have a COM1 port only installed in your system,
you should install the DSP Modem as COM2. If you have both
COM1 and COM2 installed in your system, you should install
the DSP Modem as COM3, etc.
* You may need a 486 PC with 8MB of RAM (or more) when running
a MIDI application with 9600 or 14,400 bps modem.
4. FAX INFORMATION
* Now Included is V.17 for fax transmission at 14.4kbps.
* PLEASE NOTE that Class 2 fax emulation is not included
with this release.
* When viewing faxes using the QuickLink fax viewer, there
can be lines of "noise" in viewed faxes. This is observed
when scrolling the faxes in the fax viewer. The line noise
is annoying, but is not saved to the fax file at all.
* You can not remove a scheduled fax from the fax schedule list
in QuickLink if the Call Manager is in the process of sending
the scheduled fax. Close down the Call Manager and then go
to the fax schedule to delete the fax.
5. TELEPHONE ANSWERING MACHINE (TAM) INFORMATION
* You should try out your microphone to find the optimum speaking
distance to avoid clipping. The way to do this is to go into
QuickLink MessageCenter(tm) - QLMC - open the Messages dialog, and
record a greeting using the microphone. If, when playing this
greeting, it is too loud or very choppy-sounding you should move
away from the microphone and re-record it. For a wide range of
microphones, twelve inches or so seems to be a good distance
between the person speaking and the microphone.
Experience reveals that with DSP modem TAM, the following
microphone characteristics produce the best results:
- Uni-directional (works best for general purpose usage like
recording greetings)
- Impedance 600 ohms
- Mono Dynamic
- Cardiod
Using a desk-top microphone stand, placed approximately 12-18
inches from the person speaking, has also proven to be beneficial.
While this is not an endorsement of any kind, we have found the
Radio Shack Model 33-1073 microphone to be compatible with the DSP
modem TAM function. Using this microphone requires using a 1/4-inch
stereo female to 1/8-inch stereo male adapter between the
microphone and the DSP modem adapter MIC connector.
* If the caller hangs up during the Greeting, QLMC will save a blank
message in the Log.
6. AUDIO SYSTEM INFORMATION
* Audio wave recording depends on a variety of factors including the
processor speed, the amount of free disk space, data fragmentation
on the hard disk, and the application being used. Here are some
tips which may improve recording results:
- Erase unnecessary files from the hard disk.
- Use a defragmentation program to create a large contiguous
free region on your hard disk.
- If using the Mwave Recorder, increasing the amount of memory
available to Windows may improve recording. To do this, run
the Control Panel in the Main program group. Double click
the "Drivers" icon or select "Drivers" from the
"Settings" menu. Select the "MCI Sound" entry in the list
box. Press the "Setup" button. You will be presented with
a scroll bar. Moving the slider to the right will
increase the amount of memory that Windows makes available
for wave recording. The default setting allocates four
seconds of memory. Increasing this amount may help.
- Try an alternate audio recording application. Audio
programs are implemented in a variety of ways. Some
implementations are better suited for a particular
scenario than others. For example, try recording with
either the Windows Sound Recorder or the Mwave Recorder.
Some computers, particularly those with 16 MHz 386
processors, have been observed to hang or produce poor
quality recordings when using higher sample rates and
resolutions. In particular, attempting to record 44 KHz 16
bit stereo may prove to be difficult on all but the fastest
computers.
* If you are running PC3270 for Windows, it is recommended that you
close your host session before using the Mwave synthesizer.
Alternately, you should stop playing the synthesizer when running
PC3270 for Windows. PC3270 for Windows and the MIDI synthesizer
will not run simultaneously.
* When the MIDI Synthesizer attempts to play notes above the range of
available samples, a default tone will play at the correct pitch
but with a simple bell-like timbre. This scenario can be avoided
by transposing the part being played down one or more
octaves. This transposition can be performed by standard
sequencing software.
Alternately, this transposition can be performed by the MIDI Mapper
in the Windows Control Panel. By associating the "-1 octave" Key
Map with the instrument in the Patch Map, that instrument's notes
will be lowered by an octave and the default timbre will be avoided.
* Sounds can be associated with various Windows events via the
Windows Control Panel. If other Mwave components such as the Mwave
Modem, FAX, or Telephone Answering Machine are in use when such an
event occurs, it is possible that no sound will be produced.
Furthermore, Windows may display a pop-up window indicating that
the sound driver is currently in use and not available. Please
ignore any such warnings. To avoid this warning, you can turn off
sound in the sound control panel of the Windows control panel.
7. CD-ROM
The CD-ROM drives that can attach to the DSP modem are Panasonic models 562
and 563. These CD-ROM drives will cable easily to the card. You should
use the MSCDEX.EXE driver to enable CD-ROM functions. The MSCDEX.EXE
driver is available from Microsoft. This driver also ships with most
CD-ROM drives.
The audio cables for these CD-ROMs come in two varieties. The first
cable, which can be used with the DSP modem, has a connector that has three
pins in it. The second cable, which cannot be used with the DSP modem,
has four pins and cannot be used with the DSP modem.
If you get this cable with your CD-ROM, you should contact the place from
which you purchased the CD-ROM in order to get a cable that will work
properly.
The flat ribbon cable with a 2x20 connector MUST be installed so that
the pin 1 mark, usually a dot or arrow, coincides with the dot on the
card. Refer to the User's Guide for details.
8. DOS Games Audio Enhancement
Allows most DOS games designed to run on a Sound Blaster
or compatible sound card to run on the IBM DSP card.
8.1 General Information
The IBM DSP provides audio for most DOS and Windows games.
A small number of games run in DOS protected mode and do
not work with the IBM DSP.
To use the IBM DSP, the DOS game must run in a Windows DOS
session. To start a DOS game from Windows, choose one of
the following procedures:
- From the Main group in Windows' Program Manager, double
click on the MS-DOS Prompt icon, and then follow the
instructions in the game's user's manual for starting
the game.
- From the game's directory, enter "WIN" followed by the
startup command for the game. This will start Windows,
go to a DOS session under Windows, and start the game.
For example: WIN XWING
When you finish the game, you can exit Windows by typing
Alt+F4 and then Enter.
The IBM DSP Mwave drivers use the Sound Blaster/Adlib interface
for DOS Games Audio. The IBM DSP Mwave drivers are automatically
loaded the first time the game tries to access the Sound
Blaster/Adlib interface. Most DOS games automatically detect the
presence of this interface, but for those games that ask what kind
of sound board is installed, choose Sound Blaster, Sound Blaster
Pro, Sound Blaster 16, or Adlib. Some games perform differently
for each interface, so if you are not getting the performance that
you expect, try reinstalling the game and select a different interface.
8.1.1 VOLUME CONTROL
To adjust the volume while you are playing a game:
Increase volume: Ctrl+Alt+U
Decrease volume: Ctrl+Alt+D
8.1.2 TELEGAMING
With this release, DOS games can be run at the same time as the
IBM DSP 2400 bps modem. Usually it is easier to load the modem
before you start to play the game. See your IBM DSP User's Guide
for complete instructions on using the 2400 bps modem.
8.2.TROUBLESHOOTING PROBLEMS WITH DOS GAMES
The manufacturers of DOS games use a wide variety of techniques to
give their games unique functions and performance. This diversity
can cause problems for the user. This section attempts to give you
help and guidance for some of the most commonly encountered problems
such as insufficient memory. But, the best reference is the user's
manual for the specific game that is a problem. The game
manufacturers usually provide extensive help and suggestions
to overcome problems unique to their game.
8.2.1 UNSUPPORTED MODES
Your IBM DSP hardware does not currently support digitized sound
in either "Direct Mode" or "ADPCM Mode" . For the few games which
use these modes (some examples are listed below in the section
entitled "Hints to Help with Specific Games"), we suggest that you
try the following:
For games which use direct mode, try setting the game up to run on
an Adlib card rather than on a Sound Blaster. This will probably
disable all digitized sounds, but will allow the game to run with
synthesized music. If you find that your game suddenly runs VERY
slowly for a while, selecting Adlib may improve performance.
For games which use ADPCM mode, you need not make any changes.
However, you will not hear any digitized sounds which use ADPCM.
Otherwise, the game should continue to run normally.
A few games (most of them from Microprose) attempt to produce
speech using FM synthesis. This feature is not supported by Mwave.
Speech produced this way may sound garbled.
8.2.2.SETTING THE DOS ENVIRONMENT VARIABLE
A few games require that an environment variable be defined which
will point the game to the location of the sound hardware. If you
have such a game, you must put the following line in the
AUTOEXEC.BAT file:
SET BLASTER=A220 I7 D1 T3
Please refer to your DOS manual for instructions on editing files.
When you have finished, reboot your machine.
In this line, "A220" tells your game that sound hardware can be
found at port address 220. Similarly, "I7" and "D1" tell the game
to use interrupt level 7 and DMA channel 1. These are the default
settings that were used when you installed your IBM DSP software.
If you have changed these settings, the "SET BLASTER= . . ." line
must be changed accordingly. Please refer to your IBM DSP User's
Guide for information on changing these settings, or see the section
entitled "Game Audio Port Address, Interrupt Line, and DMA
Channel" below.
8.2.3.GAME AUDIO PORT ADDRESS, INTERRUPT LINE, AND DMA CHANNEL
Most games automatically determine the port address, interrupt line,
and DMA channel settings for the DOS games audio hardware. But if the
game asks for this information, specify a port address of 220,
interrupt line (IRQ) of 7, and a DMA channel of 1. These are default
settings in the IBM DSP Mwave driver. In the unlikely event that you
need to change these settings, you may edit them using the setup panel
for the Mwave Games driver. To view this panel, open the Control Panel
application in the Main group of Windows' Program Manager and then open
the Drivers control panel. Click on Mwave Games and then click on
Setup. The setup panel appears, allowing you to change these settings.
8.2.4.CONFLICTS WITH OTHER HARDWARE
Generally speaking, DOS games will not run on a machine with two Sound
Blaster-compatible sound cards installed. Nor will they run on
IBM DSP if another card is present. If you already have such a card
in your computer, it is recommended that you disable the "DOS Games
Audio" function on your IBM DSP card. Please refer to your User's
Guide to learn how this is done, or see the section entitled
"Disabling DOS Games Audio" below.
8.2.5.DISABLING DOS GAMES AUDIO
The setup panel for the Mwave Games driver contains an Enable Games
control. Instructions for viewing the setup panel can be found in
the section "Game Audio Port Address, Interrupt Line, and DMA Channel"
above. An X in the Enable Games box enables the IBM DSP's DOS Games
Audio options, while an empty box indicates that this option has been
disabled. One reason for disabling the IBM DSP DOS Games Audio option
would be the presence of another sound adapter in your computer.
If you want to use a different sound adapter just for games, and
the IBM DSP for other applications, remove the X from the Enable
Games box.
8.2.6.HINTS TO HELP WITH SPECIFIC GAMES
4-D Boxing -
This game uses some ADPCM digitized sounds, which will not
be heard on IBM DSP.
Chessmaster 3000 -
Be sure to run "SBLASTER.COM" before starting the game. It must
be run in the DOS session in which Chessmaster will be run.
Comanche - Maximum Overkill -
Comanche will not run under Windows.
Commander Keen IV -
This game will take about a minute to initialize itself before
you can begin to play. The words "Initializing . . .
Please Wait" will flash while this is happening.
Doom -
Doom will not run (with sound) under Windows.
F-15 Strike Eagle II -
F-15 II will not run under Windows.
F-15 Strike Eagle III -
Unless you have a very fast computer, low resolution graphics
must be used to get acceptable performance. See the game
manual for more information.
F117 -
This game will not run on this version of Mwave DOS Games Audio.
Falcon 3.0 -
This game uses direct mode digitized sounds, which may cause
the program to run very slowly during the introduction as two
planes fly by, and when you crash. To avoid this, configure
your game for "none" under "radio messages" and for "Adlib"
under "music".
Front Page Sports Football -
This game will not run unless you install the patch disk,
available from Sierra Customer Service (phone: 800-SIERRA5).
Also, the game must be set to run on an Adlib card rather
than a Sound Blaster.
Kid's Zoo (and other games from Knowledge Adventure) -
For best results, edit the PIF file for "Kid's Zoo" (ZOO.PIF)
so that "High Graphics" is not selected from the "Display
Options" in the "Advanced Options". Otherwise, the game might
hang occasionally. Note that a "High Graphics" option also
appears in the first screen of the PIF editor. Ignore
this option, click on "Advanced . . ." , and edit the entry
in the "Advanced Options" page only.
Please look in your Windows User's Guide for help using the
PIF Editor.
Links386 -
Links386 will not run with sound under Windows.
Lemmings & Lemmings 2 -
On some computers, Lemmings 2 will occasionally run either
too fast or too slowly. Exit the game, start again, and
it will usually run at the correct speed. The original
Lemmings will not run under Windows.
Lost Files of Sherlock Holmes -
This game uses ADPCM digitized sounds, which will not be
heard on IBM DSP. Also, the program which displays the
Electronic Arts logo might hang. You can get around the
logo screen by running the program "GAME.EXE" rather than
"HOLMES.BAT".
Manhole -
This game uses direct mode digitized sounds, which will not
be heard on Mwave. Music will play.
Martian Memorandum (and other games from Access) -
Under Windows, Martian Memorandum often hangs as it begins
to run. If the program makes it to the first screen, it
will run properly. Deleting the configuration file, MM.CFG,
and restarting the game will sometimes help.
Murder Makes Strange Deadfellows -
This game will not run on this version of Mwave DOS Games Audio.
Populous II -
This game uses ADPCM digitized sounds, which will not be heard
on IBM DSP. Also, the program which displays the introduction
might hang. You can get around the logo screen by running
the program "POP2 /SS".
The Presidents (and other games from National Geographic) -
This game will not run on this version of Mwave DOS Games Audio.
Prince of Persia II -
Occasionally the introduction will stop after the first few
words. When this happens, you can usually continue play by
pressing the Enter key.
Rebel Assault -
Start Rebel Assault by entering "REBEL2" at the DOS command
prompt. If the game hangs, try removing EMM386 from your
CONFIG.SYS, reboot, restart Windows, and run "REBEL2" again.
Return to Zork -
From the list of audio cards supported, choose "mostly Sound
Blaster compatible". The audio in the opening scene might
break up occasionally, depending upon the speed of your
machine. The rest of the game runs fine.
Starcon II -
This game does not provide sound support when running
under Windows.
Syndicate -
This game does not provide sound support when running
under Windows.
Undersea Adventure (and other games from Knowledge Adventure) -
For best results, edit the PIF file for "Undersea Adventure"
so that "High Graphics" is not selected from the "Display
Options" in the "Advanced Options". Otherwise, the game might
hang occasionally. Note that a "High Graphics" option also
appears in the first screen of the PIF editor. Ignore this
option, click on "Advanced . . .", and edit the entry in
the "Advanced Options" page only.
Please look in your Windows User's Guide for help using
the PIF Editor.
Where In xxx Is Carmen San Diego -
Most of the games in the Carmen San Diego family will now run
on Mwave. However, the version of "Where in the World is
Carmen San Diego, Deluxe" which has a 1992 copyright will not
run under Windows. Therefore it will not run on Mwave.
Copyright 1993 versions will work on Mwave.
8.2.7.MAKING MORE MEMORY AVAILABLE TO GAMES
Many DOS games require lots of DOS memory, and some even require you
to start your PC from a "clean boot" disk. Check the game's user's
manual for special instructions.
Some games will give you a message, "not enough memory", when you
attempt to start the game, but some will just lock up the computer,
if you do not have enough memory. With DOS 5.0 or later, you should
be able to free over 590 KBytes of memory in a DOS session of Windows,
which should be sufficient for most DOS games. Here are some
suggestions to get the maximum memory available:
Use the DOS command: MEM /C to determine how much free memory is
available.
If you are using MS-DOS 6.0, run the MEMMAKER program that comes with
DOS to automatically make changes to your CONFIG.SYS and AUTOEXEC.BAT
files.
If you are using MS-DOS 5.0, use EMM386 and HIMEM to load any necessary
device drivers (such as CD-ROM) into high memory. Consult your DOS
User's Guide for information.
Create a "clean boot" disk, (using the directions below) and start your
computer with this disk before starting Windows.
Finally, the manufacturers of DOS games that require unusually large
amounts of memory realize that they have a potential usability problem,
and as a result they usually provide extensive help and suggestions
in the game's user's manual. If you are not successful with the
suggestions given here, the best reference is the user's manual for
the specific game that is a problem. Refer to their directions for
creating more free memory, usually in the technical supplement or
troubleshooting section.
8.2.8.CREATING A CLEAN BOOT DISK
1. Put a blank disk in the A: drive and type the following at the DOS
prompt:
FORMAT A: /S
2. Create a CONFIG.SYS file something like:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS
DOS=HIGH, UMB
FILES=20
BUFFERS=15
STACKS=0,0
(This example assumes Windows and DOS are located on the C: drive.)
If your game requires expanded memory, eliminate NOEMS in the second
line of the above CONFIG.SYS sample and replace it with nnn RAM,
where nnn is the amount of expanded memory required by the game
(see the game's user's guide).
To make the best use of high memory, any "DEVICE= . . ." statement
that you add to the CONFIG.SYS sample should be changed to
"DEVICEHIGH= . . ." . (Do not change the DEVICE=C:\DOS\HIMEM.SYS or
DEVICE=C:\DOS\EMM386.EXE NOEMS statements.)
3. Create an AUTOEXEC.BAT file something like:
@ECHO OFF
PROMPT $p$g
PATH=C:\WINDOWS;C:\DOS
LOADHIGH C:\DOS\MOUSE.COM
NOTE: Today, most games require a mouse, therefore we have included a
statement to load your mouse driver into high memory
(LOADHIGH C:\DOS\MOUSE.COM), but if your game does not use the mouse
you may remove this statement.
Do not include programs like SMARTDRV.EXE in your AUTOEXEC.BAT
4. Start the computer with this "clean boot" disk in the A: drive.
5. Start Windows
6. Double click on the MS-DOS Prompt icon in the Main group in Windows'
Program Manager.
7. Start the game as directed in the game's user's manual.
8.2.9.IMPROVING PERFORMANCE OF DOS GAMES IN A WINDOWS SESSION
A few DOS games run slower in a Windows DOS session than in native DOS.
Check the user manual of your game for special instructions about
improving performance. You might try configuring Windows to use the
VGA display driver rather than a higher resolution or less efficient
driver. Also, see if your game allows you to turn off
"background music" and only play special effects.

10.CORRECTIONS TO THE 'IBM V.32bis DSP Data/Fax Modem' USER'S GUIDE
Due to rapid changes and additions to the DSP Modem functions
this product is now known as the IBM DSP Modem and Audio Adapter.
This description applies to the user's guide as well.
p. 2 The list of option package contents should also include:
- DSP Modem Install Diskette - Diskette 3
p. 15 Step 6 of Using the Mwave Verification Program should state that the
diagnostics program will prompt you to remove all cables, excluding
phone line cables, for both the basic and advanced diagnostics
procedures.
p. 25 Step 5 of Installing the DSP Modem Support Drivers directs the user
to proceed to step 12 on page 29 if "Complete Installation of IBM_DSP
System" is selected. This is incorrect. The user should proceed
with step 6. Step 6 also directs the user to continue with step 12.
If a Selective Installation is being performed, however, the user
should instead continue with step 11 on page 28.
p. 28 If you are performing a Complete Installation, step 11 is skipped.
p. 38 The section Starting the Modem on this page states that the modem
object will initially be minimized (i.e. displayed as an icon).
Actually, the modem object may start off as a full-sized window.
p. 47 The Game choice that is mentioned in the Options section should be
called the Audio/Image Synch choice.
p. 49 The Record Format dialog box shown on this page may be slightly
different from the actual dialog box in the Mwave Recorder program.
