WINDOWS DRIVER UPDATE Aug 17, 1992 Version 1.4 BETA This is the latest release of improved Windows drivers for the Pro AudioSpectrum family of audio cards from Media Vision. Media Vision will continue to do testing, bug-fixing, and enhancements. We recommend that you make a backup of your existing drivers before using the ones provided with this release. If you discover any further bugs, please notify us via CompuServe ID 75300,2772. WARNING: The powerful nature of Media Vision's Windows drivers exceed the ability of Windows' Control Panel Driver Installation applet. We have provided SETUP.EXE to automate the installation process. We strongly recommend that you use SETUP to install the drivers. If you are comfortable with editing system.ini yourself, you may wish to install the drivers manually. If you insist on using the control panel to install, use the following procedure: TO INSTALL USING THE CONTROL PANEL APPLET: 1) From Windows, run the Control Panel's drivers applet. 2) Click on the Add button. 2 1/2) Now would be a good time to add the [MCI] CD Audio driver if you have a CD 3) Select 'Unlisted or Updated Driver' 4) Select browse and find the directory where the new drivers are 5) Select the appropriate WAVE/MIDI/AUX driver for your hardware. (This will cause all other drivers for your hardware to load as well) Allow the system to overwrite per-existing drivers. 6) Restart Windows TO INSTALL USING THE MEDIA VISION SETUP UTILITY: 1) Insert the Windows Drivers Disk. 2) CD to the drive that contains that disk 3) Type WIN SETUP TO INSTALL WINDOWS DRIVERS MANUALLY: 1) Copy *.drv, *.dll, *.cfg and *.386 from the Windows drivers disk to the \WINDOWS\SYSTEM directory. 2) Copy *.exe from the Windows drivers disk to the \WINDOWS directory. 3) Make the following changes to your system.ini file: [386Enh] device=*vdmad <-- make sure this line is first (Win 3.1 only) device=vpasd.386 <--- add this line for PAS PLUS, 16 or CDPC dmabuffersize=64 <--- add this line device=vadlibd.386 <-- remove this entry if you have it device=vsbd.386 <-- remove this entry if you have it device=vtbd.386 <-- add this line for ThunderBoard [mci] WaveAudio=mciwave.drv 9 <--- should already be there Sequencer=mciseq.drv <--- should already be there CDAudio=mcicda.drv <--- should already be there mixer=mcimixer.drv <--------- add this line [drivers] timer=timer.drv midimapper=midimap.drv midi=opl3.drv <--- for PAS Plus, PAS 16 and CDPC only midi=mvfm.drv <--- add this if you have the original PAS midi=adlib.drv <--- add this for ThunderBoard or Thunder & Lightning midi1=mvproaud.drv <--- add this line Wave=mvproaud.drv <--- add this line for PAS Plus, 16 or CDPC Wave=tbwave.drv <--- add this line for ThunderBoard only Wave=tlwave.drv <--- add this line for Thunder & Ligtning only Mixer=mvmixer.drv <--- add this line aux=mvproaud.drv <--- add this line Wave1=sbwave.drv <--- for PAS 16 only (adds 2nd wave driver) Also you must add the following line to system.ini's [mvproaud.drv] section: buffer=32 4) Add the following executeables to your Windows desktop: PMIX.EXE, PREC.EXE, PROMIX.EXE, MIX.EXE GENERAL NOTES 1) Central Point's BACKUP and PCTOOLS 7.1 are reported to be installing their own VDMAD.386 over the Windows 3.1. Central Point's VDMAD.386 has the wrong version number and will prevent mvproaud.drv from loading. 2) After changing one or more MIDI drivers, check the control panel's MIDImapper applet. Channels 1 thru 10 should be patched to the MIDI interface and channels 13 thru 16 should be patched to the on-board synthesizer (MVFM.DRV or OPL3.DRV When playing 'Old Style' MIDI files (not General MIDI) use the Vintage MIDI file patch map. 3) Pro Mixer has two extra sliders on the Pro-16 that are not documented in the manual. The BLSTR channel is the volume selector for the Snd Blaster compatible DAC output. The REC IN slider controls the recording level of the sum of the signals mixed for recording. 4) Pocket Recorder has greyed-out compression controls. They will be enabled when compression becomes part of the Multimedia Windows architecture. 5) TrakBlaster Pro does not support the higher IRQ's or DMA's. 6) We have provided a small program called DMAFIX.EXE that restores the DMA channels to a safe state when run after running TrakBlaster Pro. We suggest you make a file called TBPRO.BAT that has 3 lines in it: @ECHO OFF FILE_REQ DMAFIX Make sure you copy DMAFIX.EXE to your TrakBlaster Pro subdirectory. TrakBlaster Pro leaves the DMA channel in a state that causes Windows to slow to a crawl. This program is a temporary fix. We will contact Volker Zinke, the author of TrakBlaster Pro, to make the correct fix. ********************************************************************** CONTACTING MEDIA VISION ********************************************************************** Media Vision, Inc Main: (800) 348-7116 or (510) 770-8600 3815 LaurelView Ct.

See MCIMIXER.WRI for details of the command set. MVMIXER.DRV This is Media Vision's Mixer driver. The mixer driver adds mixer state information to your WIN.INI file: [mvmixer.drv] LineIn1=SYNTH MUS] PLAY L=100% R=100% @=0000 LineIn2=MIXER MIX] PLAY L= 72% R= 72% @=0000 LineIn3=AUX AUX| PLAY L=100% R=100% @=0000 LineIn4=CD CDA| PLAY L= 0% R= 0% @=0000 LineIn5=MIC MIC| PLAY L= 0% R= 0% @=0000 LineIn6=DIGITAL WAV] RECORD L= 0% R= 0% @=0000 LineIn7=SPKR SPK] PLAY L=100% R=100% @=0000 LineIn7=BLSTR WAV] PLAY L=100% R=100% @=0000 LineOut1=MASTER AMP| PLAY L= 79% R= 79% @=0000 LineOut2=RECORD WAV| PLAY L=100% R=200% @=0000 StereoEnhance=ON Loudness=ON Bass=50 Treble=78 SaveSettingsOnWindowsExit=YES LINE FIELD: There are 7 input Lines and 1 output line. Note: the Pro AudioSpectrum 16 has a second output line. PATCH NAME: The field immediately after the '=' is the patch name. These names (ie. SYNTH) appear in promix.exe at the bottom of each slider pair. DEVICE TYPE The next field is the device type field. The device type determines the type of icon displayed in MIX.EXE Each device type has a standard 3-letter mnemonic name that can be obtained by calling mixGetDeviceName. The current list of types is: N/C No Connection SPK PC speaker CDA Compact Disk Player AAT Analog Audio Tape AUX Auxillary DAT Digital Audio Tape MIC Microphone TEL Telephone VTR Video Tape Recorder MIX Mixer VDP Video Disc Player EQU Equalizer MUS Musical Instrument AMP Amplifier WAV Digital Waveform Player LPA Phonograph Audio RAD Radio TVA Television Audio UNK Unknown Device Type The fourth character indicates whether the user is responsible for making the physical device connection. Think of the character as the mounting bracket of an audio card. A hole, the '|' character, represents a mini phone jack. If the fourth character is ']', the connection is made by the driver. The '|' character indicates a jack or connector must be hooked up before audio can be heard. User-friendly applications may use this information to remind the user to connect a particular device. OUTPUT CONNECTION The next field corresponds to the internal mixer connection info. The word PLAY indicates that input is routed to the PLAY output (LineOut1). RECORD means the input is routed to the ADC circuitry. VOLUMES If it isn't obvious, the L= and R= fields specify the volumes of the left and right channels at start-up. ASSOCIATION This field is used to save information that specifies a relationship between a mixer input and some other device in the system. For example, if there are two CD's in the system and one is connected to LineIn4 and the other is connected to LineIn3, the dwAssociation can be used to determine which MCI CD device is on which input. MISC The other lines are self explanatory. In the future we will let users change the settings through control panel's driver setup. CHANGING WIN.INI As an example, if you connect your Walkman to LineIn3 (AUX), you can replace the word AUX with RADIO. Then, change the device type field to RAD| ///////////////////////////////////////////////////// MVPROAUD.DRV This driver supports WAVE (digital sound) audio, MIDI I/O and auxillary volume control. This driver keeps configuration information in your system.ini file under the header [mvproaud.drv] If it fails to find that entry, it will check to see if MVSOUND.SYS is loaded and use it's settings. Failing that, it will look for the outmoded [mvwave.drv] and [mvmidi.drv] entries. As a last resort, the driver will default to IRQ=7 and DMA=1. When our aux driver is the only one referred to in the drivers section, a call to auxGetNumDevs returns a value indicating 4 aux devices are in the system: Device 0 is internal CD-ROM volume Device 1 is auxillary (line in) volume Device 2 is microphone volume Device 3 is master volume While we provide a Multimedia Mixer library, we also support the existing volume control calls, auxGetVolume and auxSetVolume, when this driver is installed. VADMAD.386 system patch file required for digital audio under Windows 3.0 VPASD.386 This driver provides extra buffer space needed to handle 16-bit digital audio. If you experience problems with using audio during a Windows DOS session, remove this driver from system.ini. VTBD.386 This driver provides device contention services for the ThunderBoard. OPL3.DRV OPL-3 is the name of the Yamaha FM-synthesizer chip on the PAS Plus, PAS 16 and CDPC. This driver treats the OPL-3 as a stereo MIDI device. MMMIXER.DLL MMMIXER.DLL is like MMSYSTEM.DLL in a couple of ways. First, it provides a driver-independent layer for all mixer API's. Second, it loads any mixer device drivers in the system. This DLL was developed to provide MultiMedia developers better control over audio mixing functionality than is afforded by the current volume API's. We have offered this DLL to Microsoft and the MPC council as a standard for Multimedia Windows volume control. There See the MIXSPEC directory for detailed information on the Multimedia Mixer API. OEMSETUP.INF This file allows you to add drivers to Windows using the drivers applet in the control panel. TBWAVE.DRV This is the .WAV driver for the ThunderBoard. TLWAVE.DRV This is the .WAV driver for the Thunder & Lightning. MVFM.DRV This driver is for the original Pro AudioSpectrum. It supports the two OPL-2 chips on that card as a single stereo MIDI device. SBWAVE.DRV This is a Snd Blaster compatible WAVE driver for the Sound Blaster compatible section of the Pro AudioSpectrum 16. It can be used in addition to the mvproaud.drv wave driver giving Windows the capability to play two digital audio sounds at once. WINDOWS APPLICATIONS --------------------- MIX.EXE This program allows you to modify those mixing controls that you'll want to change most often. Its main difference from promix is that it doesn't cover nearly as much screen area. PROMIX.EXE ProMix can be launced from the WIN.INI 'load' line. If you have Windows 3.1, use the Program Manager's File/Preferences menu item to select the open minimized option. Here's a nifty feature: When running Windows, you can use the keyboard to affect the volume and the equalization CTRL-ALT-U raises master volume CTRL-ALT-D lowers master volume CTRL-ALT-M Mutes the amplifier CTRL-ALT-S Toggles Stereo Enhance CTRL-ALT-L Toggles Loudness CTRL-ALT-B Sets BASS mode CTRL-ALT-T Sets TREBLE mode When in Treble or Bass mode, you can affect the level: CTRL-ALT + Increases BASS or TREBLE level CTRL-ALT - Reduces BASS or TREBLE level ProMix now features a real-time VU meter that will display the current recording level. The VU meter will be active all the time on the PAS Plus and PAS 16 but on the CDPC and origintal PAS, the VU meter will only be active during recording and playback of digital audio.

Q: What do I need to do before I install the PAS16 Windows Drivers disk? A: If you have the PAS8 Windows drivers installed or have an older version of PAS16 drivers, go into the Control Panel, Drivers, and remove every driver which references Pro AudioSpectrum or Media Vision. Restart WIN31 and then install the new drivers. Or, if you have Norton Desktop For Windows which will interfere with our Windows Driver's INSTALL program. To work around the problem, go into SYSTEM.INI, [boot] section. Replace "SHELL=NDW.EXE" with "SHELL=PROGMAN.EXE". Install the Windows drivers, restart WIN31, and make sure that all sounds work. Replace the "PROGMAN" by "NDW" in SYSTEM.INI. Restart WIN31. Go into Program Manager, File, Run to execute "SETUP /P" so that Norton will register the Multimedia Tools Group which has just been created by the INSTALL program. Or, if you are using DR DOS 6.0's SHARE which causes our INSTALL program to crash the system. To work around the problem, remove SHARE. Re-boot the computer. Then install our Windows drivers. 2. Q: While installing the PAS16 WIN31 drivers, I get the error "You must first load Multimedia Extensions." A: First, go into the Control Panel, Drivers applet to check the installed drivers list. There must be MIDI Mapper, Timer, [MCI] Sound, [MCI] MIDI Sequencer. Second, check the SYSTEM.INI file. Under the [boot] section, there should be "DRIVERS=MMSYSTEM.DLL". If any of these items are missing, WIN31 has not been properly installed. Installing WIN31 over an older version of windows may have caused this problem. The only solution is to install WIN31 from scratch and then install the PAS16 WIN31 drivers again. 3. Q: After the PAS16 WIN31 drivers installation, runing WIN31 causes the error "Can't find ver. 2.00 of VDMAD.386." A: Some Windows applications replace this driver by their own DMA driver, such as Norton tape backup software which puts under the [386Enh] section of the SYSTEM.INI, the statement "DEVICE=VDMADX.386". First, put a semi-colon ";" infront of the whole statement. Second, add the statement "DEVICE=*VDMAD" to the beginning of the [386Enh] section. Restart WIN31 and try again. 4. Q: After the PAS16 WIN31 drivers installation, running WIN31 causes the computer to lock up. A: This is caused by a DMA and/or IRQ conflict. Check for all possible conflicts; a bus mouse is usally set for IRQ 5 which will conflict with the SB IRQ 5 default setting. Use a text editor to go into SYSTEM.INI. Go the the end of the file to locate [MVPROAUD.DRV] and change the DMA and IRQ settings. Bring up WIN31 and try again. 5. Q: Do I need MVSOUND.SYS for Windows? A: Currently, yes. In the future, the PAS16's Windows drivers will not have to depend on MVSOUND.SYS. 6. Q: Can I use different IRQ and DMA settings under Windows, than under DOS? A: The DMA set in SYSTEM.INI for Windows can be different from the DMA set in CONFIG.SYS for DOS as long as WIN31 is started in 386-Enhanced mode. However , if you start WIN31 is started in standard mode, you make make the settings the same. 7. Q: What is the advantage of using a high-order DMA and IRQ? A: High-order DMA allows 16-bit DMA transfer which enables the MVPROAUD.DRV sound driver to handle digital audio more efficiently and also to provide more available DMA selections. High-order IRQ only provides more available IRQ selections. 8. Q: I have just received the latest version of the PAS16 Windows Drivers Disk. Do I have to remove the older version first? A: Yes. After removing the old drivers, restart Windows and then install the new drivers. 9. Q: Sound plays normally under DOS using the selected DMA and IRQ setttings, but loops under Windows using the same DMA and IRQ settings. A: This is caused by an IRQ conflict. Edit the SYSTEM.INI file to change the IRQ setting under [mvproaud.drv] section. 10. Q: Pro Mixer's wave meter points at the beginning of the red area instead of at zero. A: Our future release of WIN31 drivers v1.4 will correct this problem. Please check with Customer Service after 9/1. 11. Q: What do I have to do before I can record using Pocket Recorder or Sound Recorder? A: Go into Pro Mixer or Pocket Mixer to set the audio input source to recording mode. 12. Q: When I record at 16-bit mode, there is very bad clipping or it does not work at all. 8-bit recording works fine. A: If you are using an low-order DMA then change to a 16- bit DMA under the [mvproaud.drv] section of SYSTEM.INI and try again. 13. Q: Recording at 8-bit is very scratchy. 16-bit recording does not have this problem. A: The PAS16 has a 16-bit PCM DAC. Recording at 8-bit using a 16-bit DAC is definitely more noisy than recording at 8-bit on the PAS8 which only has an 8-bit DAC. In the next release, Pocket recorder will have a feature to convert a 16-bit recorded file to 8-bit to resolve the problem. Please check with Customer Service after 9/1 to find out if WIN31 Drivers and Pocket Tools v1.4 is available which will have this feature. 14. Q: Does the Pocket Recorder support the Cut, Copy and Paste features? A: These features will be supported in the next release. Please check with Customer Service after 9/1 to find out if WIN31 Drivers and Pocket Tools v1.4 is available. 15. Q: I get the errors "Can't find input device with pid." and "Can't find output device with pid." when trying to run Pocket Recorder. A: Make sure the MVSOUND.SYS statement appears in CONFIG.SYS and that the driver loads properly when the computer boots up. 16. Q: I get the error "PREC has caused a General Protection Fault error in USER.EXE..." A: This error occurs most frequently in 286 computers and also in faster computers which have less than 2MB of virtual memory under Windows. To help us troubleshoot this problem, first, please download PRECGPF.ZIP (PREC.EXE with GPF error checking) from the BBS. Second, run DRWATSON.EXE (a WIN31 utility). Third, run the new Pocket Recorder. When WIN31 issues the GPE, all the necessary information are stored in DRWATSON.LOG. Fourth, print out this log and fax it to Technical Support. Upon receiving the information, we will forward to Engineering and await their response. 17. Q: If Pocket Recorder is used to record a 16-bit wav file, and is saved then played from Media Player, the file will play properly to the end but the thumb button on the position slider will not have eached the end. The thumb button usually stops around the halfway mark. If the position button is dragged to the right of this mark, the message "The specified parameter is out of range for the specified command" will pop up. Dragging past the halfway mark and playing the file sometimes results in white noise. A: This problem has been reported to Engineering and will be fixed in the future release of WIN31 Drivers v1.4. Please contact Customer Service after 9/1 to find out if this is available. 18. Q: While recording under Pocket Recorder, if I open/close/use other applications, there are licking/popping sounds that also get recorded. A: This problem has been reported to Engineering and is currently being researched. 19. Q: Pocket Recorder's OLE (Object Linking & Embedding) does not work properly. A: The OLE feature is not fully implemented. Please document the problems in detail and fax or mail to Technical Support to be forwarded to Engineering. 20. Q: Pocket Recorder issues "Cannot write WAV files". A: This problem is caused by slow system throughput. First, make sure VPASD.386 is installed in SYSTEM.INI. This driver allocates a 32KB buffer for faster DMA transfer. Second, take out SMARTDRV and STACKER, if installed. Third, increase the CPU speed, if possible. 21. Q: A file recorded using RECFILE.EXE (PAS16's DOS utility) plays back fine under Pocket Recorder but this same file will not play back under Media Player. And under Sound Recorder, loading this file will cause the "General Protection Fault Error In Sound Recorder". A: A new version of RECFILE.EXE, dated 6-22-92 or later, does not have this problem. On BBS, download P16REC.ZIP; on Compuserve, download TOOLS.ZIP. 22. Q: How do I play CD-Audio under WIN31? A: First, put a CD-Audio disk into the CD-ROM drive. Failure to do this will cause the [MCI] CD-Audio driver to not install properly Second, go into the Control Panel, Drivers. Click on the Add button. Select "[MCI] CD-Audio" driver. Click on the OK button. WIN31 will prompt you for the Microsoft Windows Disk 4. Third, after this driver has been properly installed, go into Media Player. Select Device. CD-Audio should be one of the choices for you to select from. If not, edit MPLAYER.INI to change "CDAUDIO=0," to "CDAUDIO=17, CDAUDIO". 23. Q: I do not get any FM sound when I run DOS games under the DOS shell of Windows. A: The OPL3 FM synthesizer chip on the PAS16 can operate in either OPL3 (4-operator) mode or 3812 (2-operator) mode. Under Windows, Voyetra's OPL3.DRV driver puts this FM chip into the OPL3 mode to produce rich FM sounds. However, existing games only support the 3812 mode. This driver will put the OPL3 chip back in 3812 mode upon exiting WIN31 to go back to DOS. However, wihle still under Windows, if the user attempts to run a DOS game or application which supports AdLib, FM sound will not play. To work around this problem, go into SYSTEM.INI, [drivers] section, change MIDI=OPL3.DRV to become MIDI=MVFM.DRV. Then restart Windows. Go into the Control Panel, MIDI Mapper. Click on New. Give it a name like "3812 mode". Under the Port Name column, select "Media Vision FM Synth" for channels 1-10 and 13-16 and then save the setup. Now DOS games and applications can produce FM sounds. 24. Q: Under Media Player, CANYON.MID plays properly but when I play other MIDI files, I don't hear any music. A: WIN31 only supports General MIDI. The MIDI files that you have may be Non-General MIDI. Try the following. Go into Control Panel, MIDI Mapper. Select the Pro AudioSpectrum setup. Click on Edit. Under the Port Name column, select "Media Vision FM Synth" for channels 1-10 and 13-16 and then save the setup. Now all MIDI songs should play; however, they may not sound correct. 25. Q: Do you have PAS16 drivers for Windows 3.0 with Multimedia Extentions? A: Download from the BBS a file called MVPROAUD.ZIP. This file contains a special version of MVPROAUD.DRV for Windows 3.0 with MME. Replacing the MVPROAUD.DRV that came with the PAS16 WIN31 Drivers disk with this version is all you need to do. *************************PAS.EXE**************************** 1. Q: How do I adjust the volume for the SB section of the sound card. A: Run "PAS SET SB TO XX" where xx is 0-100. 2. Q: DOS software produces no volume or very low volume, especially after exiting WIN31. A: Run "PAS RESET" and try again. 3. Q: When I run "PAS *", how do I enable the recording mode for an input source? A: Use the up and down arrow keys to move to the input source desired. Then press the Enter key to toggle between PLAY and PLAY & RECORD. *********************RECFILE, PLAYFILE********************** NOTE: Before running RECFILE.EXE, make sure that you have run PAS * to enable the recording mode for the input source(s). See the PAS.EXE section above. 1. Q: How do I use the command parameters Vxxx, V+xxx and Fx for RECFILE.EXE? A: Vxxx, where xxx is a number from 000-127 for voice- activated level. Only sounds at and above this level get recorded. V+xxx, where xxx is 000-127. Record all when voice is activated at threshold. Fx, where x is between 0-6 and selected using the following guidelines: Filter Value Limiting Frequency Sampling Rate Frequency Range 18 KHz 44 KHz near CD 5 16 KHz 32 KHz cassette 4 12 KHz 24 KHz FM radio 3 9 KHz 18 KHz AM radio 2 6 KHz 12 KHz telephone 1 3 KHz 6 KHz male voice 0 0 KHz mute 2. Q: When PLAYFILE.EXE starts and stops, it produces a "popping" sound. A: Get a newer version of PLAYFILE.EXE. Please download P16REC.ZIP from the BBS. 3. Q: I am having trouble recording 16-bit wave files using the V+xxx parameter. A: Get a newer version of RECFILE.EXE. Please download P16REC.ZIP from the BBS. 4. Q: I do not hear any sound when I play back under WIN31's Media Player a file which has been recorded using RECFILE.EXE. A: Get a newer version of RECFILE.EXE. Please download P16REC.ZIP from the BBS. 5. Q: I get the error "File is full or blocked" when I run RECFILE.EXE. A: This problem is caused by slow system throughput. First, try running RECFILE with the /M parameter to allocate as much memory to RECFILE as possible. Second, reduce to a generic CONFIG.SYS and AUTOEXEC.BAT. Third, make sure the hard disk has been optimized (unfragmented). Fourth, try at a lower sampling rate or try recording to a ramdrive (use DOS's RAMDRIVE.SYS). *********************CD-ROM APPLICATIONS******************** 1. Q: After running Compton's Multimedia Encyclopedia, I only hear sounds out of one channel. A: When Compton's plays digital audio (represented by .WAV file extension), it puts the CD-ROM drive into mono mode and also shuts down one channel. For a temporary solution, you need to do a cold boot to reset the CD- ROM drive. To resolve this problem, download COMPTONS.ZIP from the BBS or contact Customer Service to have this file sent via mail. 2. Q: While installing MS Bookshelf, at 99% completion, installation aborts with an error message in SETUP.INF file. A: First, back up SETUP.INF. Second, go into SETUP.INF and remove all lines that start with a semi-colon ";" and then save it and re-install Bookshelf 3. Q: National Geographic Society's Presidents Starting With George runs fine but does not produce audio. A: This application uses IBM Linkway and supports SB. During installation, the driver statement "DEVICE=SNDBK12.SYS 1" gets added to CONFIG.SYS. This driver defaults to IRQ 7 and I/O port 220h and DMA 1. The SB section of the sound card defaults to IRQ 5 and I/O port 220h. Edit the CONFIG.SYS to show "DEVICE=SNDBK12.SYS 1 5 220", where 5 is for IRQ 5 and 220 is for I/O port 220h, or which ever settings you have at J10 and J12 on the sound card. ********************BUS MASTERING DEVICE******************** 1. Q: I hear periodic clicking sound or static noise whenever the hard disk's light goes on (while drive is being accessed). A: Lower the bus on-time and increase the bus off-time by the same amount so that the on-time is smaller than the off-time, or experiment to find the best ratio. We discovered this from using the Adaptec 1542B SCSI Hard Disk Controller. The install program for this card adds the following statements to CONFIG.SYS: DEVICE=C:\ASPI4DOS.SYS /N11 /F5 DEVICE=C:\ASPIDISK.SYS Where N11 is 11/16ms and F5 is 5/16ms (default settings). The problem was resolved when we changed to N5 and F11. ********************OS/2 DRIVER SUPPORT********************* 1. Q: Are there any plans to support OS/2 v2.0? A: Yes, we are currently working on it. Please contact Customer Service after 10-1-92. ********************WINDOWS NT SUPPORT********************** 1. Q: Are there any plans to support Windows NT? A: Please check with Customer Service after 10-1-92.
