After the install is complete, shut down Windows and reboot the computer. ---------------------------------------------------------------------- 2.6 Turning Mwave OFF and ON in DOS ---------------------------------------------------------------------- NOTE: The following section applies when you shutdown or boot to: - Native DOS only from Windows 3.x - MS-DOS mode only from Windows 95 If you are running Mwave under DOS only, type the following commands from the DOS prompt: o MWAVE OFF--To turn Mwave off o MWAVE START--To re-initialize Mwave and begin a fresh session without rebooting o MWAVE ON--To restart Mwave with the same settings as the previous session o FASTCFG--To change application types If you use MWAVE OFF to stop Mwave and then use FASTCFG to restart Mwave, you must change the application type. ====================================================================== 3.0 FREQUENTLY-ASKED QUESTIONS (FAQs) ====================================================================== This section contains answers to questions about certain features and capabilities provided by Mwave applications. ---------------------------------------------------------------------- 3.1 FAQs about the Mwave Modem ---------------------------------------------------------------------- Q: What should I do if I answer an incoming phone call with the handset and then discover that the call is a fax or modem transmission? A: Fax machines and modems are usually set up to call back several times if they fail to make a connection. Therefore, hang up and, when the fax machine or modem calls back, allow the PC to answer the call. Mwave enables the PC to discriminate (determine the call type) and either pass the call to the open fax or modem application, or take a message for a voice call. Q: Why don't I hear modem sounds when I run the Microsoft Hardware Compatability Test (MHCT) for the modem? A: The MHCT tests the modem's M2 command. M2 is the command to keep the speakers on all the time. Mwave's DSP maps the M2 command to M1, which commands no sound when the modem is connected. Therefore, no sound is heard when tested. Q: How do I get Windows 95 to automatically load the Mwave Modem when Windows 95 starts? A: Add the following command to the "RUN=" line of the Windows section in the WIN.INI file X:\MWW\MODEM\MWMWIN.EXE after any existing commands. Q: What settings do I need to use when I install a communications appli- cation (such as ProComm or CrossTalk)? A: Your communications software requires that you provide a modem type, a baud rate (i.e, the speed of your modem), and the COM port to which the modem is attached. The chart below describes settings required by Mwave: To set this... Select highest ranking available setting... ------------------------------------------------------------------- The Modem type 1. Mwave modem 2. Generic Hayes-type modem 3. User-defined modem 4. Hayes SmartModem 2400 5. Hayes modem 6. Hayes compatible modem 7. Other (Note: If you select a modem of type "Other," you must include the proper modem initialization string. For most applications, the initialization string "AT&F" will work. See the Mwave Modem online help for more information.) Baud Rate 57,600 bps, or the maximum setting offered by your communications software. COM Port COM 2 Q: What can I do if my 300 baud modem connections are unreliable? A: Use the next higher setting (or baud rate) and try again. It is recom- mended that you use the highest possible setting of your Mwave Modem. Q: What port speed should I use when I connect my modem at 2400 bps? A: If you attempt to force the modem to connect at 2400 bps by setting the port speed to that value, the connection may not be made or it may fall back to 2400 nECL or 1200. To avoid this problem, set the port speed to a higher value. Q: What host application transfer protocol is recommended for best Mwave Modem performance? A: For best throughput when sending or receiving data, select the highest-ranking available transfer protocol listed here. 1. ZMODEM 2. Kermit-95 3. Ymodem-G 4. TEXT 5. ASCII 6. XMODEM (only as a last resort) For more information, see Section 5.1 Recommendations for Optimum Mwave Modem Performance. ---------------------------------------------------------------------- 3.2 FAQs about Mwave FAX Capabilities ---------------------------------------------------------------------- Q: What setting should I use for the "fax/modem type" when I set up my Class 2 FAX software to work with Mwave if "Mwave Modem" isn't listed as an option? A: For all FAX applications, if "Mwave Modem" is not listed, select "Generic Class 2" or some comparable label from the application's list of supported fax/modems. Q: What should I do if I answer an incoming phone call with the handset and then discover that the call is a fax or modem transmission? A: See first Q & A in the above section, FAQs About the Mwave Modem. Q: What are Mwave's fax restrictions? A: Mwave supports fax transmissions of monochrome text and images up to 8 1/2 inches wide (A4 width). Mwave does not support B4 width trans- missions. Q: I am using FaxWorks Voice and have difficulty receiving a fax when the SENDING machine is using Mwave Version 1.0 or 1.1. Is there any way to correct the difficulty? A: Recording a new outgoing greeting in the FaxWorks Voice application may correct the situation (check "Record a New Greeting" in the FaxWorks Voice help). Upgrading the SENDING machines Mwave to Version 2.0 will also correct the problem. Q: Is there any way to correct the difficulty I have sending a fax using Microsoft FAX? A: Uninstalling and reinstalling the fax application (using Add/Remove Programs in the Control Panel) corrects the problem. ---------------------------------------------------------------------- 3.3 FAQs about Mwave Audio Features ---------------------------------------------------------------------- Q: Can I use the Windows 95 mixer interchangeably with the Mwave mixer? A: The standard Microsoft mixer application was not designed for the Mwave hardware platform. Therefore, you should only use the Mwave audio mixer for controlling audio. To access the Mwave mixer click Start, point to Programs, point to Mwave Thinkpad, and click Mwave Audio. NOTE: To place a shortcut icon for the Mwave mixer on your desktop, see the Windows 95 help. Q: Why can't I play a compact disc through Windows 95's "My Computer"? A: Windows 95 must have its CD Player installed before you can play CDs through My Computer. To make sure the Windows 95 CD Player is loaded: 1. Select Settings from the Start menu, then select Control Panel. 2. Double-click the Add/Remove Program icon. 3. Select the Windows Setup tab. 4. Select Multimedia. 5. Select the CD Player check box, then click OK. Q: Why don't I hear any sound when playing a MIDI file with Windows 95's Media Player? A: You won't hear any sound when playing a MIDI file if your MIDI drivers have not been configured for Mwave. To make sure that Mwave is prop- erly configured: 1. Select Settings from the Start menu. 2. Select the Control Panel. 3. Select Multimedia. From the multimedia screen, select "MIDI". Select "Single instrument" and highlight "Mwave MIDI Synthesizer". Q: Why do I receive an error message when I try to play an Mwave Synthesizer Samples .WAV file in an audio application? A: The Mwave Synthesizer uses samples in the form of *.WAV files installed on the hard disk to play music. These WAV files are intended solely for use by the synthesizer and are formatted correctly for this purpose. However, if for some reason a user tries to use an audio application to play the *.WAV files individually, the applica- tion may respond with an error message. This does not indicate a problem in using the files for their intended purpose. Q: How can I prevent the noise in my 8 bit recordings? A: An 8 bit recording is naturally noisy. To reduce the noise level of your recording, use 16 bit recording. Q: How do I get Sound Blaster games to run after a suspend/resume when it has been running with MIDI? A: Stopping MIDI will not enable Sound Blaster games to run correctly. Instead, close and then reopen the Sound Blaster application. Q: Sound Blaster games run after a suspend/resume but my Telephone Answering Machine (TAM) cannot receive calls. How do I reactivate the TAM? A: Close and then reopen the Sound Blaster application. Q: How do I restore the sound to games such as DOOM or DOOM II running in a Windows 95 DOS session after a suspend/resume? A: Close and then reopen the game application. Q: Why do I hear pauses when I play an audio wave (.WAV) recording from a floppy diskette? A: These pauses during playback occur due to the slower rate of data transfer from the diskette. To fix the problem, copy the wave (.WAV) file to your hard disk. Q: Why does my .WAV file I just recorded sound "broken"? A: "Broken" or discontinuous sound is often the result of either the slower data transfer rate from a floppy drive, or you recorded the .WAV file to a drive that is compressed (using DriveSpace, DoubleSpace, or Stacker). In both cases, the playback application cannot receive data fast enough and, as a result, you hear the gaps in the transaction. To fix this problem, you can: o Record the .WAV file to a fixed disk (i.e., C: ). o Lower the record rate to 22 KHz or 11 KHz, change to 8 bit, and/or change to mono sound. Most applications allow you to adjust these parameters, and less taxing record rates may solve the problem. o If you use a disk compression program (such as DriveSpace, DoubleSpace, or Stacker), direct the recorded data to an uncom- pressed drive. This way, the computer can process the sound without taking the time to uncompress/compress the information. Refer to Section 5.2 Audio/MIDI Technical Notes for additional tech- nical information. Q: Why don't I hear sounds from my game or CD when the Mwave Modem is also running? A: Mwave manages the workload of the digital signal processor, the device that allows you to play sound, use telephony, etc. If you don't hear sounds from your DOS game or CD, it is likely that Mwave is using the modem to send a file or has set the modem to answer the telephone. Wait for these other tasks to finish. You should then hear the sounds from your game or CD. Q: Why does the volume on 8 bit recordings seem softer than 16 bit recordings? A: Most prerecorded 8 bit wave files, like those included with applica- tions or Windows, are compressed to improve their signal-to-noise (S/N) ratio. These compressed files are much louder than the uncom- pressed audio (wave, synthesizers, MPEG) in the system. To compensate for loud prerecorded 8 bit audio, Mwave tasks reduce the playback level of all 8 bit recordings. The volume reduction is done with 16 bit precision, so the S/N ratio is NOT reduced. The reduced and compressed 8 bit audio plays slightly louder than typical uncom- pressed 16 bit audio, and slightly reduces the volume of uncompressed 8 bit audio. Q: What happens if I change the input source of the mixer during recording? A: Changing the input source results in muting of the audio. If you inad- vertently do this, restart Windows to recover. Q: How does FASTCFG affect audio play and record? A: The audio play and record will not function if you select "Mic" as the input source. If you select "None" as the input source, the input will function as "CD" or "Line." Q: How do I stop feedback from occurring when I use my microphone? A: Lower the peak levels for playback and record for your microphone. 1. Click Start, point to Programs, Mwave, and click Audio Control. 2. Click on the MIC button. 3. Click and drag the microphone (MIC) slide controls to a lower level. 4. Resume using the microphone. (Note: When the play pushbutton is selected, make sure that the microphone check box is not selected.) ---------------------------------------------------------------------- 3.4 FAQs about Mwave's Telephone Country Selection Utility ---------------------------------------------------------------------- Q: What is Country Selection? A: The Mwave Telephone Country Selection program is used to set country specific parameters for Mwave telephony functions including Modem, FAX, speakerphone, and Telephone Answering Machine. The Mwave tele- phony drivers use the Country selection information to permit reliable and safe connection to the appropriate telephone network. ********** WARNING: Improper selection of the telephone network may cause ********** unreliable operation. ---------------------------------------------------------------------- 3.5 FAQs about Mwave's Sound Blaster Emulation ---------------------------------------------------------------------- Q: What sound card does Mwave emulate? A: Mwave emulates a Sound Blaster 1.5 (SB) card. See additional information in Section 5.3 Sound Blaster Technical Notes in this file. ---------------------------------------------------------------------- 3.6 FAQs about Mwave and Loading Windows 3.x or Windows 95 ---------------------------------------------------------------------- Q: Why can't I open Windows after receiving the following message: "Mwave Warning: Mwave has detected a memory condition that may adversely effect Windows operation. Windows will not be started. Restarting your machine may solve this problem. If this message displays again, read \MWW\README.TXT" A: This message typically calls attention to memory resources used by Mwave and DOS "terminate and stay resident" (TSR) programs, such as DOSKEY. To avoid the warning message and start Windows, you can: o Make sure that Mwave is loaded after the TSRs by verifying that the "CALL MWAVE START" statement in your AUTOEXEC.BAT file follows all calls to load TSR programs. For Windows 3.x: o Restart your PC if you invoke a TSR before you launch Windows. o Modify the MWW\MWAVE.INI file to start regardless of the TSRs you have loaded in memory. Add the line WINSTART=YES to the {MWAVE} section of MWAVE.INI. (Note: If you choose this option, Windows will lose the use of this extended memory which may affect per- formance.) For additional information on the memory error condition message you receive when starting Windows, see Section 4.4 Memory Problems with Windows and DOS TSRs. ---------------------------------------------------------------------- 3.7 FAQs about Using Mwave and Other DOS Applications ---------------------------------------------------------------------- Q: What should I do if can't run a DOS application, such as a word processor, that does not use Mwave features (e.g. Mwave Modem, Mwave Games, etc.)? A: Some DOS applications may not run if they try to use resources con- sumed by Mwave. You can run these applications after you turn off Mwave features. At the DOS prompt, type MWAVE OFF to turn off Mwave. To resume use of Mwave once you finish with your DOS application, type MWAVE ON at the DOS prompt or reboot your computer. ====================================================================== 4.0 COMPATIBILITY ====================================================================== Read through this section if you have any problems with a specific appli- cation working with Mwave. ---------------------------------------------------------------------- 4.1 Communications (Modem) Applications ---------------------------------------------------------------------- o Connecting to Prodigy When attempting to use the Mwave Modem to connect to Prodigy using a 2400 bps Y (Tymnet) connection, the connection fails.

The suggested fix from Microsoft is to add the line "exclusive=0" under the {SFSremote} heading in \WINDOWS\MSMAIL.INI. o Windows for Workgroups 3.11 The Remote Access Support (RAS) doesn't recognize the connected response from the Mwave modem. The IBM Personal Computer Company (PCC) Bulletin Board Service (BBS) provides a MODEM.INF file with the correct Mwave information. You should obtain this file and add the information to the \WINDOWS\SYSTEM\MODEM.INF file. o Windows for Workgroups (WFW) and Communications Applications in Windows 3.x Some communications applications hang on the second attempt to use the COM port. This condition occurs because the SERIAL.386 driver provided with WFW 3.11 does not properly handle UART First In--First Out (FIFO) capabilities. To fix this problem, obtain the WG1001.EXE fix from Microsoft. (You may also find this file on the IBM ThinkPad Forum on CompuServe.) In some cases, you may need to replace WFW's \WINDOWS\SYSTEM\COMM.DRV with COMM.DRV from Windows 3.1 to completely solve the problem. (You may also find additional compatibility solutions in Section 5.0 OTHER TECHNICAL NOTES.) ---------------------------------------------------------------------- 4.2 Windows FAX Applications ---------------------------------------------------------------------- Mwave Class 2 Fax is compatible with the following Windows Fax applica- tions: o Delrina's WinFax Lite version 3.0 and WinFax Pro version 3.0 o Delrina's WinFax Pro version 4.0 o BIT Software's BitFax Pro version 3.07 o Cheyenne's Bitware Lite version 3.22 o Trio's Data/Fax Lite version 4.1E o Trio's Data/Fax o Microsoft's Exchange (Windows 95 Fax) version 4.0.410.59 o Phoenix Technologies' Eclipse Fax version 6.0 o Hayes's SmartCom Fax version 1.01B o Smith Micro's QuickLink version II 1.4.3 o Smith Micro's QuickLink Gold version 1.2 o Sofnet's FaxWorks Pro version 3.0 The following applications are not currently compatible with Mwave Class 2 Fax: o Hayes's SmartCom Data/Fax Pro version 1.0A o BIT Software's BitFax for Windows version 2.09D o Datastorm's ProComm Plus for Windows Fax version 2.00 o Datastorm's ProComm Plus for Windows versions 2.10 and 2.11 o Microsoft's Windows for Workgroups Fax version 3.11 o Delrina's WinFax Lite version 2.0 The following items provide specific information about the fax applica- tions mentioned above. o Delrina's WinFax Pro version 4.0 If you are installing WinFax Pro 4.0 as a new application, you may encounter the following questions and error messages.

Ignore this message. General Usage Note: Many Fax applications offer a custom communications (COM) driver that may improve Fax transmission speeds. Mwave uses the Windows default COM driver when testing these applications. If a tested application does not perform, verify that the Windows default COM driver statement, "comm.drv=comm.drv", is in the {boot} section of the \WINDOWS\SYSTEM.INI file. (NOTE: You can use an editor such as Notepad.) Problems may occur because an applications COM driver is not compatible with other applications. In addition, some applications will not give you the opportunity to change a non-default COM driver, regardless of compatibility. ---------------------------------------------------------------------- 4.3 DOS FAX Applications ---------------------------------------------------------------------- Mwave Class 2 fax is compatible with the following DOS Fax applications: o Delrina's DOS Fax Lite version 3.0 o Delrina's DOS Fax Pro version 2.0 o Cheyenne's BitFax version 4.05A The following items provide specific information about the fax applica- tions mentioned above. o Delrina's DOS Fax Pro version 2.0 The Mwave modem must be running before initializing and using DOS Fax Pro. o Cheyenne's BitFax version 4.05A Each time you start BitFax, send a fax before attempting to receive faxes. This ensures that BitFax can receive Class 2 faxes from the Mwave modem. Delrina's DOS Fax Lite version 2.00 is not currently compatible with Mwave Class 2 Fax. ---------------------------------------------------------------------- 4.4 Memory Problems with Windows and DOS TSRs ---------------------------------------------------------------------- Loading programs such as DOS TSRs (e.g. DOSKEY) in memory after Mwave loads may result in a memory error condition and prevent Windows from starting. There are three ways you can get past the message and start Windows. o To start Windows in most general purpose situations: Load Mwave last, after all other items, for it to function properly. Check the contents of your AUTOEXEC.BAT file to make sure Mwave loads last: 1. Open the AUTOEXEC.BAT file with an editor. 2. Verify that "CALL MWAVE START" follows all calls to TSR programs. 3. Restart your computer. o To start Windows after invoking or using a DOS TSR: If you invoke certain programs (such as TSRs) in DOS before you start Windows, you may encounter memory errors. To avoid these memory prob- lems, you must restart your PC before launching Windows. o To override the problem and start Windows without unloading TSRs: In some situations, you may want to continue with Windows while the TSRs consume memory resources. If your PC has more than 8 MB of RAM, this should not pose a problem. If your PC has less than 8 MB of RAM, you may experience slower performance from Windows. In Windows 3.x you can bypass this memory condition by modifying the \MWW\MWAVE.INI file. To accomplish this: 1. Open \MWW\MWAVE.INI in an editor. 2. Add the parameter WINSTART=YES in the {MWAVE} section. 3. Restart Windows. (Note: Windows may lose the use of extended memory if it loads while TSRs are present, which negatively affects Windows performance. Make sure that you consider this possibility before editing the .INI.) ---------------------------------------------------------------------- 4.5 Recording Problems with TalkWorks** AudioRecorder ---------------------------------------------------------------------- When you use TalkWorks AudioRecorder with Mwave and select 8 kHz 8 bit stereo for recording, a monoaural signal is recorded instead of the intended stereo signal. ---------------------------------------------------------------------- 4.6 Other Applications and Mwave ---------------------------------------------------------------------- o Lotus Notes 3.x Lotus Notes 3.x does not properly recognize the Mwave modem. Lotus does not include an .MDM file that describes the Mwave commands and responses. To fix this problem, obtain a copy of the MWAVE.MDM file from the PCC BBS and add it to the \NOTES directory. Follow these steps: 1. Start Lotus Notes 3.x. 2. Select the modem configuration. The list of choices should now include the Mwave modem. 3. Choose the Mwave modem from the list. 4. Return to Notes and use as you usually would. o Windows 95 Volume Control The Mwave Audio Control and the Windows 95 Volume Control applica- tions are not synchronized. Using both controls simultaneously results in incorrect settings. In order to avoid this situation, operate only one audio controller. Microsoft is investigating this Windows 95 device driver problem. o Windows 95 Phone Dialer ThinkPad does not support connection of the handset necessary for Windows 95's Phone Dialer. ====================================================================== 5.0 OTHER TECHNICAL NOTES ====================================================================== This section provides additional technical information and support for specific uses of Mwave functions and/or applications. ---------------------------------------------------------------------- 5.1 Recommendations for Optimum Mwave Modem Performance ---------------------------------------------------------------------- IBM recommends the following settings or conditions for best performance from your Mwave Modem: o For best throughput when sending or receiving data, select the highest-ranking available transfer protocol listed here. 1. ZMODEM 2. Ymodem-G 3. TEXT 4. ASCII 5. XMODEM (only as a last resort) o If you are operating in Windows 3.x, try to ensure that your communi- cation application fully utilizes the First In--First Out (FIFO) capabilities provided by Mwave. Specifically, the application should fill the FIFO six (6) or more characters per interrupt during transmit. o You should enable Hardware Flow Control. Use the Hayes command AT\Q3. o Select a modem protocol from this list, with (1) providing the best performance, and (6) giving the worst. Protocol AT Commands use to get protocol ------------------------------------------------------------ 1. V.42 / V.42bis AT\n7"H3 2. MNP 1-4 / V.42bis AT\n3"H3 3. MNP 1-4 / MNP5 AT\n3"H0 4. V42 AT\n7"H0 5. MNP1-4 AT\n3%C0"H0 6. non-error corrected AT\n0 Refer to the online help available in Mwave Modem for explanation of the AT commands required to use one of the above modem protocols. o Trouble Connecting at 28.8 kbps If you experience difficulties connecting at a modem speed of 28.8 kbps to a particular number, or if you have trouble connecting to a particular modem rotary, try the following. - If the connection is not made and the speaker is OFF: 1. Disable V.42 bis and MNP 5 using AT"H%C 2. Disable V.42 (AT\N3) or MNP 1-4 (AT\N5). You could also disable both with AT\N. - If the connection is not made and the speaker remains on: 1. Reduce the maximum modem throughput using the AT commands ATS28=18 (for 26400 bps), ATS28=17 (24000 bps), ATS28=16 (21600 bps), or ATS28=15 (19200 bps). 2. If you've tried step 1 and it still does not connect, use AT*TH8 to control the speed. Once you connect using the AT*TH8 command, remember to reset your modem using either AT&F (for factory defaults) or AT*TH4. If you forget to reset, your next calls will transmit at lower V.34 connection rates. ---------------------------------------------------------------------- 5.2 Audio/MIDI Technical Notes ---------------------------------------------------------------------- o Additional Memory Requirement for Complete MIDI Sample Set in Windows 3.x The Mwave internal sampled sound synthesizer comes equipped with a complete General MIDI sample set. Depending on how extensively this capability is used, up to 3 MBytes of memory may be required. Here are some tips which may improve MIDI performance: - Remove all RAM disks from your AUTOEXEC.BAT. - Remove SMARTDRV from your AUTOEXEC.BAT or reduce the amount of memory allocated to the SMARTDRV cache. The line in your AUTOEXEC.BAT should be: C:\WINDOWS\SMARTDRV.EXE 256 0 - Use the standard VGA video driver for Windows. Run Windows System Setup from the Main Program Group, select Options and Change System Settings, then select the VGA Display driver. o Recording Audio Successful recording of audio Wave (.WAV) files depends on a variety of factors including processor speed, amount of free disk space, data fragmentation on the hard disk, and the type of application used. Some computers, particularly those with slower processors, either "hang" the system or produce recordings with gaps. These conditions occur when using high data rates, such as 44 KHz, which means the computer cannot keep up with the data transfer. If you attempt to record 44 KHz 16 bit stereo Wave files using a slower PC, you may encounter problems. Here are some tips that may improve recording: - Erase unnecessary files from your hard disk. - Lower the record rate to 22 KHz or 11 KHz, change to 8 bit, and/or change to mono sound. Most applications allow you to adjust these parameters. - Use a Hard Disk Defragmentation program (usually included with Norton Utilities or Central Point PCTools) to create more contig- uous space on your drive. This keeps the slower PC from having to work too hard (and take too much time) looking for available disk space. NOTE: You can use the Disk Defragmentation utility. Windows 95 includes this utility under Start/Programs/Accessories/System Tools/Disk Defragmenter. - If you use a disk compression program (such as DriveSpace, DoubleSpace, or Stacker), direct the recorded data to the tempo- rary drive created by the compression program or to an uncom- pressed drive. Again, the computer then can process the sound without taking the time to uncompress/compress the information. NOTE: Windows 95 users can find additional information on the disk com- pression program DriveSpace under Start/Help/Index/DriveSpace. DOS users can find additional information on the disk compression program DoubleSpace: DOS 6.x users must type HELP DBLSPACE at the DOS prompt, and IBM DOS 7.0 users type HELP STACKER at the DOS prompt. - Use an alternative audio recording application. Audio programs use a variety of techniques to record and playback sound. Some may work well in situations where others fail to perform. For a basic test, try recording with the Windows Sound Recorder. ---------------------------------------------------------------------- 5.3 Sound Blaster Technical Notes ---------------------------------------------------------------------- The "SET BLASTER=" Command A few games require that DOS uses an environment variable to identify the location of the sound hardware. For such games, the following line is added to the AUTOEXEC.BAT file during installation: SET BLASTER=A220 I5 D1 This parameter... Tells your game to... ----------------- -------------------------------------------- A220 locate the sound hardware at address 220 I5 use interrupt level 5 D1 use DMA channel 1 These are the default settings created during the installation of Mwave. If you change these settings after installing a new peripheral card, the "SET BLASTER=..." line must be changed accordingly. ---------------------------------------------------------------------- 5.4 Notes about DOS Mode Support ---------------------------------------------------------------------- Windows 95 does not support Mwave functions if you attempt to access the Startup Menu by pressing F8 during bootup and then selecting the Command Prompt Only option. Windows 95 supports normal Mwave DOS functions (games, modem, class 2 fax) while in MS-DOS mode or in a Windows 95 DOS session. ---------------------------------------------------------------------- 5.5 Notes about Windows 95 Configuration ---------------------------------------------------------------------- Using the ThinkPad Features application to change the IRQ, DMA, etc. may not affect/alter Mwave's setup. In order to be certain of the settings, perform any setting changes through Windows 95. ---------------------------------------------------------------------- 5.6 Notes About the Mwave Speaker Phone ---------------------------------------------------------------------- Some speaker phone volume controls malfunction at maximum output. There- fore, if the volume slider is at maximum volume and you cannot hear the other party, lower the slider to 75% volume.
