Note:  Some computers do not support high-order DMA and IRQ.  Please contact the computer manufacturer for assistance.

******************************PAS16'S I/O ADDRESS MAP*******************************
Refer to page 1-43 and 44 in the PAS16 User's Guide.
	
DEFAULT DMA, IRQ AND I/O PORT SETTINGS
*************USED BY THE SOUND BLASTER SECTION OF THE SOUND CARD*************
DMA 1.  This setting is fixed if SB compatibility is enabled.
IRQ 5 at default.  Selectable between (2,3,5,7) by changing jumper J12 on the sound card.
I/O 220h at default.  Selectable between (220h,230h,240h) by changing jumper J10 on the sound card.
The version of SB's DSP (processor) that is supported is v1.5.

*************************STANDARD TROUBLESHOOTING STEPS***********************
Generic CONFIG.SYS:
	DEVICE = C:\WINDOWS\HIMEM.SYS
	FILES =  30
	BUFFERS = 10
	LASTDRIVE=X
		(For CD-ROM drive.  Refer to the SCSI INTERFACE section below.)
	DEVICE = C:\PROAUDIO\MVSOUND.SYS D:X Q:X V:X J:X T:X 
		(Refer to the PAS16 SOFTWARE INSTALLATION section below.)
	DEVICE = C:\WINDOWS\SMARTDRV.EXE 2048 512
	DEVICE=C:\PROAUDIO\TSLCDR.SYS /D:MVCD001 /R /P:3
		(SCSI CD-ROM driver.  Refer to the SCSI INTERFACE section below.)

Generic AUTOEXEC.BAT:
	@ECHO OFF
	PATH = C:\;C:\DOS;C:\WINDOWS;C:\PROAUDIO
	PROMPT $P$G
	C:\PROAUDIO\MSCDEX.EXE /D:MVCD001 /M:10 /L:X /V
		(CD-ROM driver.  X is the drive letter assigned to the CD-ROM drive.  Refer to 		the SCSI INTERFACE section below)
	
1.	Reduce to the generic CONFIG.SYS and AUTOEXEC.BAT.
2.	Reduce the computer's CPU speed.  Usually this can be accomplished by turning off the TURBO mode or disabling the internal/external memory cache by going into the computer's CMOS setup.
3.	Reduce the computer's bus (I/O CLK) speed to 8MHz.  The PAS16 was designed around the IBM AT specification which uses this bus speed.  Please note that this is not the same as the CPU speed.  Once everything works fine at 8MHz bus speed, you can experiment at a higher bus speed.
4.	Remove other peripheral boards from the computer, such as scanner board, tape backup,...
5.	Try the PAS16 in another 16-bit slot.
6.	Try the PAS16 in another computer.
7.	If you do not hear any sound, recheck the speakers/headphones connections.

*************************PAS16 HARDWARE INSTALLATION****************************
1.	Q:	Do I have to change any jumpers before I install the PAS16?
	A:	The default settings will work in most computers.  Only try with different IRQ (at jumper J12) and I/O port (at J10) settings if you experience any problems or know that these settings are used by another peripheral board in the same system.

2.	Q:	How do I change the DMA and IRQ settings for the PAS16 section of the sound card?  
	A:	The PAS16's DMA and IRQ can be changed by changing the D:x and Q:x parameter on the MVSOUND.SYS statement in the CONFIG.SYS file.

3.	Q:	How do I change the IRQ and I/O port settings for the SB section of the sound card?
	A:	The SB's IRQ and I/O port can be changed by changing the jumpers at J12 and J10 on the sound card.  

4.	Q:	Can the PAS16 section and the SB section share the same settings?
	A:	No.  The settings must be different to prevent a DMA and IRQ conflict.

5.	Q:	What are the symptoms of a DMA and IRQ conflict on the PAS16 section?
	A:	DMA conflict causes digital audio to be distorted or no digital audio.  It can also cause system to hang, reboot, or issue parity error.
		IRQ conflict causes digital audio to loop and no synthesized audio.  

6.	Q:	What are the symptoms of  an IRQ and I/O port conflict on the SB section?
	A:	The game does not produce digital audio or digital audio is distorted, or, running the game causes the computer to lock up.

7.	Q:	What causes a Memory Parity Error?
	A:	A DMA conflict.

8.	Q:	Which jumpers on the sound card can I change?
	A:	The only ones that can be changed are the SB jumpers:  J10 for I/O port, J11 for DMA 1, and J12 for I/O port.  

9.	Q:	How do I disable SB compatibility mode?
	A:	Float all of the shunts for J10, J11 and J12 (by putting the shunt on 1 pin only).  This will disable the SB's IRQ, I/O port and DMA 1.  

10.	Q:	Does the PAS16 work in a 486/50, or, What computers does the PAS16 work in?
	A:	The PAS16 was designed around the IBM AT specification.  It will work in a 486/50 if the bus (I/O CLK) speed is lowered down to 8MHz.  Please note that this is not the same as the CPU speed.  Once it works fine at 8MHz bus speed, you can experiment at a higher bus speed.

**************************PAS16 SOFTWARE INSTALLATION***************************
1.	Q:	How much disk space is needed to load all the files on the hard drive?
	A:	About 5-6MB.  

2.	Q:	What drivers can be loaded high?
	A:	If there is sufficient upper memory available, you can load MVSOUND.SYS, TSLCDR.SYS and MSCDEX.EXE high.

3.	Q:	I have just received a new version of the PAS16 Installation Disks.  Can I install it over the old version?
	A:	It is best to remove the PROAUDIO directory including all sub-directories first before you install the new version.

4.	Q:	Why does the INSTALL program only allow DMA 1 or 3 to be selected?
	A:	Most existing DOS applications only support DMA 1 and 3.  You can use a text editor such as MS DOS 5.0's EDIT to change the D:x parameter on the MVSOUND.SYS statement in CONFIG.SYS.

5.	Q:	The INSTALL program causes my computer to lock up, or, How do I manually install the software?
	A:	To manually install the PAS16 software on Installation Disks 1 & 2, do as follows: 
		Add the "C:\PROAUDIO" to the path statement in AUTOEXEC.BAT.
		Reboot the computer.
		MD C:\PROAUDIO
		MD C:\PROAUDIO\MIDI
		MD C:\PROAUDIO\WAVE
		MD C:\PROAUDIO\STEREOFX
		MD C:\PROAUDIO\TBPRO
		Copy LHARC.EXE from the PAS16 Installation Disk 1 to C:\PROAUDIO.
		Copy DIGISNDW.LZH to C:\PROAUDIO\WAVE.
		Copy MIDI.LZH to C:\PROAUDIO\MIDI.
		Copy MOD.LZH to C:\PROAUDIO\TBPRO.
		Copy PROGRAMS.LZH to C:\PROAUDIO.
		Copy PAS16.SYS to C:\PROAUDIO.
		Copy CHORD.WAV to C:\PROAUDIO.
		Rename PAS16.SYS to MVSOUND.SYS.
		Copy SFX.LZH from the PAS16 Installation Disk 2 to C:\PROAUDIO\STEREOFX.
		From the C:\PROAUDIO directory, type LHARC X PROGRAMS.LZH
		From the C:\PROAUDIO\WAVE, type LHARC X DIGISNDW.LZH
		From the C:\PROAUDIO\MIDI, type LHARC X MIDI.LZH
		From the C:\PROAUDIO\TBPRO, type LHARC X MOD.LZH
		From the C:\PROAUDIO\STEREOFX, type LHARC X SFX.LZH
		Add the following line to CONFIG.SYS DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3 Q:7
		Reboot the computer.
		
6.	Q:	What is MVSOUND.SYS for?
	A:	It enables the PAS16 to produce sound under DOS and is also required for WIN31 drivers.
	
7.	Q:	After I installed the PAS16 Installation Disks and reboot the computer, right after MVSOUND.SYS finishes loading, I hear crackling/scratchy noises coming out of the speakers.
	A:	Make sure your Installation Disks have the current version of 1.2.  Add "T:1" to the end of the MVSOUND.SYS statement.  Save CONFIG.SYS and try again.  Refer to page 1-25 of the PAS16 User's Guide v1.1 for an explanation.

8.	Q:	What parameters does MVSOUND.SYS support?
	A:	D:x, where x is (0,1,2,3,5,6,7) for DMA for the PAS16 section of the sound card.
		Q:x, where x is (2-7,10-15) for IRQ for the PAS16 section of the sound card.
		J:x, where x is 0 or 1, 1 is for Joystick Enabled (default), 0 is for Joystick Disabled.
		V:x, where x is from 1 to 100, which is the initial volume setting.
T:x, where x is 0 or 1, 1 is to use the on-board oscillator, 0 is to use the motherboard's oscillator.  
Some computers such as 486/33 OPTI have improperly-designed oscillator which causes the OPL3 FM chip on the PAS16 to produce random noises.  See Page 1-25 of the PAS16 User's Guide v1.1 for an explanation.
		Note:  Not all software support high-order DMA and IRQ (for example, TrakBlaster Pro).

***********************************SCSI INTERFACE***********************************
1.	Q:	What is TSLCDR.SYS?
	A:	This is a CD-ROM driver written by Trantor Systems.  It comes with the SCSI/Cable Driver Kit.  The current version is 1.46B.  The parameters that are supported are:
			D:x, where x is any device name that you assign to the CD-ROM device.
			R is for reset.

2.	Q:	What is MSCDEX.EXE?
	A:	This is Microsoft CD-ROM Extensions.  The current version is 2.21.  The parameters that are supported are:
			D:x, where x is the same device name that is assigned to the CD-ROM device 		by TSLCDR.SYS.
			M:x, where x is the number of 2K memory buffers, 10 is usually used.
			L:x, where x is the drive letter you want to assign to the CD-ROM drive.
			V is for a verbose listing of information about memory usage.
			E is for expanded memory usage.

3.	Q:	I don't need the SCSI or audio cable.  Can I just get a copy of TSLCDR.SYS and MSCDEX.EXE?
	A:	These drivers are royalty-bearing software which means they cannot be provided free of charge.  Also, they come with the SCSI/Cable Driver Kit only.

4.	Q:	Which CD-ROM drives can I use with the PAS16?
	A:	See the SUPPORTED CD-ROM DRIVES section above.  The PAS16 has a SCSI interface which allows it to control SCSI devices.  Please contact Media Vision Sales for the SCSI CD-ROM Cable/Driver Kit (Specify internal or external).

5.	Q:	Do I have to use the PAS16's SCSI interface to control my CD-ROM drive which has its own controller?
	A:	No.  All that you have to do is to make sure that the CD-Audio signals are routed from the CD-ROM drive to the PAS16.  There are 2 ways of doing this.  The first way is to use a custom audio cable to connect the PAS16's internal audio input at J5 to the CD-ROM drive.  This custom audio cable is part of the SCSI CD-ROM Cable/Driver Kit and is not available separately.  If you would like to build this cable, please contact Customer Service to request for the cable specification to be faxed to you.  The s


6.	Q:	I already have a SCSI adapter in my system.  Will I have to remove it if I install the PAS16?  Can multimple SCSI adapters co-reside in my PC?
	A:	You can have as many SCSI adapters in the same system as there are available slots.  The PAS16's SCSI will not interfere with other SCSI adapters.  The only possible conflicts would be conflicts with DMAs, IRQs and I/O port used by the sound card.

6.	Q:	I have the Sony CDU-535 CD-ROM drive(or Laser Library).  Can I use the PAS16 to control the Sony drive?
	A:	No.  This Sony drive uses a proprietary Sony Bus interface.  Media Vision will release the PAS16 and PASPlus Sony Bus version in the near future to work with this drive.  Please contact Customer Service after 8/1 to be added to a waiting list for us to contact you when this version is available.

7.	Q:	Can I use the PAS16 to control other SCSI devices?
	A:	Yes.  Trantor Systems can be reached at 510-770-1400 for a $59.00 driver set which supports all SCSI hard drives, removable hard drives and magneto-optical drives.  Currently there is no driver support for tape drives or scanners.

8.	Q:	I used to have the original PAS8 board and a SCSI/Cable Driver Kit and have just updated to the PAS16.  Do I need an updated version of the CD-ROM drivers?
	A:	Contact Customer Service for a free driver update for both TSLCDR.SYS and MSCDEX.EXE.

9.	Q:	I have the ATI Graphics Ultra (or Vantage) and when the TSLCDR.SYS driver loads it detects two SCSI addresses.  I also experience problems with digital audio and get a red screen on WIN31.
	A:	Make sure you have TSLCDR.SYS v1.46B or later.

10.	Q:	Which SCSI Interface is used on the PAS16?  How do I write device drivers for it?
	A:	The PAS16 uses the Zilog's Z5380.  Contact Media Vision Customer Service for documentation on the chip's specification and the PAS16 Software Developer's Toolkit.  This software toolkit is currently under development.  Customer Service is currently taking a waiting list.

11.	Q:	What is the transfer rate of the PAS16's SCSI interface?
	A:	It has a maximum transfer rate of 690KB/sec.

12.	Q:	I get the error "No SCSI host adapter found".
	A:	First, the SCSI CD-ROM driver is board dependent.  If you would like to use the PAS16 to control the CD-ROM drive, you need to use our TSLCDR.SYS driver v1.46B or later; otherwise, if you would like to use another SCSI controller (such as Adaptec or Future Domain) to control the CD-ROM drive, you need to use its driver (contact the SCSI controller manufacturer for the driver).  Second, check the internal, flat ribbon SCSI cable to make sure it is properly connected to the PAS16.  Third, make sure the r


13.	Q:	I get the error "No devices respond on this SCSI host adapter".
	A:	First, make sure one of the computer's power cables has been connected to the back of the CD-ROM drive.  Second, check the internal flat ribbon SCSI cable to make sure it is properly connected to the back of the CD-ROM drive.  

14.	Q:	I get the error "Device driver not found:  MVCD001.  No valid CD-ROM selected".
	A:	First, if you are using DR DOS 6.0, it is necessary to change the device name for both TSLCDR.SYS and MSCDEX.EXE statements from "MVCD001" to "TSLCD".  Second, make sure that the device name in both of these statements match.

15.	Q:	I get the error "Incorrect DOS version".
	A:	If you are using MS DOS 5.0, MSCDEX.EXE v2.2 requires that CONFIG.SYS has the statement "DEVICE=C:\DOS\SETVER.EXE".  You should not get this error f you have MSCDEX.EXE v2.21.  This driver comes with our SCSI/Cable Driver Kit or can be downloaded from Microsoft Multimedia BBS at 206-936-4082.

16.	Q:	I get the error "Invalid drive specification" when I type the drive letter assigned to the CD-ROM drive.
	A:	First, make sure that you have "LASTDRIVE=X" in the CONFIG.SYS file, where X is the next logical drive letter after the letter assigned to the CD-ROM drive in the MSCDEX.EXE statement.  Second, make sure that the TSLCDR.SYS driver statement precedes any driver statement that creates a RAM drive such as RAMDRIVE.SYS.  Third, check if the TSLCDR.SYS and MSCDEX.EXE drivers have been loaded up properly.

17.	Q:	I get the error "CDR 101:  Drive not ready".
	A:	First, make sure that you are not trying to read a CD-Audio disk.  Second, check in the internal, flat ribbon SCSI cable to make sure it is properly connected.  Third, move the TSLCDR.SYS and MSCDEX.EXE statements to the end of CONFIG.SYS and AUTOEXEC.BAT.  Having these statements at the beginning can sometimes cause this problem.  Fourth, reduce to the generic CONFIG.SYS and AUTOEXEC.BAT and try again.

18.	Q:	I get the error "CDR 103:  CD-ROM not High Sierra or ISO-9660 format reading drive X.  Abort, Retry or Ignore?"
	A:	First, check to make sure that you are not trying to read a CD-Audio disk.  Second, this is usually caused by a software conflict.  Reduce to the generic CONFIG.SYS and AUTOEXEC.BAT and try again.

19.	Q:	I do not hear any CD-Audio at all, or, How do I connect the internal CD-Audio cable?
	A:	The internal CD-Audio cable may not have been properly connected or it is defective.  There are two ways to route CD-Audio.  The first way is to use a custom audio cable to connect the PAS16's internal audio input at J5 to the CD-ROM drive.  This custom audio cable is part of the SCSI CD-ROM Cable/Driver Kit or included with the PRO16 Kit, and is not available separately.  If you would like to build this cable, please contact Customer Service to request for the cable specification to be faxed to you.  


20.	Q:	Does the PAS16 support CD-ROM XA?
	A:	No.  This feature may be supported in the future.
		
*********************************STEREO STUDIO FX**********************************
1.	Q:	Does SFX support 16-bit PCM recording and playback?
	A:	No.  SFX only supports 8 bits.

2.	Q:	Sound loops when playing back under SFX.  DMA 3 and IRQ 7 are set in CONFIG.SYS file.  All other applications  work fine.
	A:	First, make sure that the file is not a 16-bit recorded file.  SFX only supports 8-bit recorded files.  Second, try using a high-order DMA, such as DMA 5.

3.	Q:	Activating "Record" in SFX disconnects the channels.
	A:	This problem has been reported to Engineering.

************************************SP SPECTRUM************************************
1.	Q:	TAPIMV issues the error "FM sound card not found."
	A:	Make sure your Installation Disks have the current version of 1.2.  Add "T:1" to the end of the MVSOUND.SYS statement.  Refer to page 1-25 of the PAS16 User's Guide v1.1 for an explanation.

2.	Q:	I have the Media Vision MIDI Mate v1.0 (MIDI connector box) which worked fine on the PAS8.  After I upgraded to the PAS16, MIDI IN does not work using the same MIDI Mate.
	A:	Inside MIDI Mate, there is a chip at U1 (next to the MIDI cable) called an opto-isolator.  The old part number is 6N136.  For the MIDI Mate to work with the PAS16, it needs the new part number which is 6N138.  Contact Customer Service for an RMA number to have this chip updated if you have the old part number.

3.	Q:	The FMEDIT section in the PAS 16 User's Guide has missing pages to describe the Mixer, Display Setup, Trigger Note, Quitting, and Pop-up Windows.
	A:	Please contact Customer Service for a copy of this sent by mail.

4.	Q:	I don't hear any sound when I play a .ROL or .MID in SP Spectrum.
	A:	Make sure that Port is set to 2 for playing songs using the internal FM synthesizer.  Set Port to 1 for playing out of an external MIDI equipment.  Refer to the SP Spectrum section in the PAS16 User's Guide for additional information.

5.	Q:	I get the error "Run time error.  Divide by 0" when I run SP Spectrum.
	A:	This is caused by an incorrect setup of the memory manager, commonly seen in QEMM and Wytek co-processor in 486 machines.  Contact Quarterdeck or the manufacturer of the memory manager for assistance with reconfiguration.

*******************************TRAKBLASTER PRO************************************
1.	Q:	While running TBPRO, a MOD file plays for 20 seconds then abruptly stops and system hangs up.
	A:	This is caused by a DMA conflict.  Make sure the PAS16 section is not set for DMA 1 unless the SB compatiblity has been disabled.

2.	Q:	Does TBPRO support high-order DMA and IRQ?
	A:	No.  TBPRO only supports DMA 1,3 and IRQ 2,3,5,7.

***********************************MONOLOGUE*************************************
1.	Q:	Running Monologue causes my computer to lock up.
	A:	Monologue uses the SB section of the sound card.  Monologue defaults to IRQ 7 where as the SB section of the sound card (at J12) defaults to IRQ 5.  To change Monologue's IRQ setting to match the card's setting, run Monologue's INSTALL.  Press [F2] to select a sound accessory.  Select the "Media Vision Products" driver and press [Enter].  Use the TAB key to highlight the IRQ settings.  Then use the up arrow key to select IRQ 5 (or which ever IRQ is selected at J12).  Press [Enter] when done.  Press [F5


2.	Q:	All possible SB's IRQs at J12 have been tried and Monologue still locks up or does not produce any audio.
	A:	Select the "AdLib" driver instead of "Media Vision Products" and try again.

3.	Q:	Dr. DOS 6.0's memory manager causes Monologue to lock up the computer when using ALT-T to activate Monologue.
	A:	First, run MEMMAX -U to disable upper memory.  Second, run Monologue.  Third, run MEMMAX +U to re-enable upper memory.

4.	Q.	The TALKDRVR.SYS is missing from the Monologue v3.0 For DOS disk.
	A:	This driver was provided with Monologue v2.0 and has been removed from the disk for v3.0 by the software manufacturer (First Byte).

5.	Q:	The Monologue User's Guide indicates that there should be two 5 1/4" disks.
	A:	There is only one 5 1/4" disk.

6.	Q:	The "Alt-T" key combination does not work.
	A:	Some programs like WordPerfect or WordStar also use the same key combination which will create a conflict with Monologue.  To resolve this problem, you need to assign a new hot key combination.  Go into the Monologue directory.  Run CONFIG.BAT.  Select "Set speech and Display Parameters".  From the Info Screen, select "Skip".  Hit Tab and save this.  Back at the Main menu, select "Change Hot Key Assignment".  Choose a new Alt key combination that will not conflict with the program you wish to configure


7.	Q:	Monologue's "Alt-T" key combination does not work properly.  Sometimes it does and sometimes strange things happen.
	A:	First, delete the Monologue directory completely.  Re-install Monologue and then try again.

8.	Q:	When I run "SAYFILE filename.doc" at the DOS prompt nothing happens.
	A:	SAYFILE.BAT is missing a parameter to allow a DOC filename to be passed to the SAYF.EXE so that it can speak the file.  Modify SAYFILE.BAT by changing the third line from "SAYF" to "SAYF %1" and then try again.  Run "SAYFILE filename.doc".  Press Enter.  Then a graphical screen will display.  Press Enter again and the file will be spoken.

***********************************AUDIOMATE**************************************
1.	Q:	I am having trouble running Animator Pro with Audiomate.
	A:	TAPIMV2 needs to be updated to support Animator Pro.  Please contact Customer Service if you would like to be added to a waiting list for the update.
	
*****************LOTUS 1-2-3 FOR WINDOWS WITH MULTIMEDIA HELP******************
1.	Q:	Lotus 1-2-3 with Multimedia Help requires 4MB virtual memory to run under WIN31.  WIN31 crashes when Lotus is initialized.
	A:	Go to the Control Panel.  Select 386 Enhanced.  Select Virtual memory.  At default, virtual memory size is set to 0KB and Type is Temporary.  Select Change.  Click on the down arrow in the Type field and select Permanent.  Click on OK, and answer YES to all the prompts.  Restart WIN31 and try again.

***********************WINDOWS DRIVERS AND POCKET TOOLS***********************
The Windows Drivers disk uses InstallSHIELD v1.3 by The Stirling Group. 

1.	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 


		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


3.	Q:	After the PAS16 Windows drivers installation, starting 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:	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.

5.	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.

6.	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.

7.	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.  	

8.	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.

9.	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 8/1.

10.	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.

11.	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.

12.	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 8/1 to find out if WIN31 Drivers and Pocket Tools v1.4 is available which will have this feature.

13.	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 8/1 to find out if WIN31 Drivers and Pocket Tools v1.4 is available.

14.	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.  

15.	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 t


16.	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

	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 8/1 to find out if this is available.

17.	Q:	While recording under Pocket Recorder, if I open/close/use other applications, there are clicking/popping sounds that also get recorded.
	A:	This problem has been reported to Engineering and is currently being researched.

18.	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.

19.	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.

20.	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 chan


21.	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 w


22.	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.

************************************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.

********************************RECFILE, PLAYFILE***********************************
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
	6				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, reduce to a generic CONFIG.SYS and AUTOEXEC.BAT.  Second, make sure the hard disk has been optimized (unfragmented).  Third, 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 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.

*************************************GAMES*****************************************
All SB games use DMA1, an IRQ and an I/O port.  

Some SB games look for the following statement in AUTOEXEC.BAT:
	"SET BLASTER=A220 Q5 D1 T3", where
A220 is for I/O port 220h, or which ever I/O port is selected at J10.
Q5 is IRQ 5, or which ever IRQ is selected at J12.
D1 is for DMA 1 which is required for SB compatibility.
Try with T2 or T3 for timer.

Other SB games do not look for this statement to find the settings but allow you to set the settings via an install program or by modifying a configuration file.

A few games default to certain settings and do not allow the user to change these settings to match the board settings.

Make sure that the game's settings match with the settings used by the SB section of the sound card.  At default, the SB section uses IRQ 5, I/O 220h.  Refer to the game's user guide or contact the game manufacturer for assistance.

Some games do not work properly if the computer is running in TURBO mode.  On most computers, there is a TURBO button on the front.  If this button is not found, disabling the internal/external memory cache in the computer's CMOS setup achieves the same result.

1.	Q:	The joystick does not work at all or does not work properly when using the PAS16's joystick port.
	 A:	First,  some computers have a built-in joystick port on the motherboard.  Other computers have a multi-I/O board that has a joystick port.  Make sure that only one joystick port is enabled and the other one is disabled.  Second, if the computer is too fast that may also cause a problem.  Reduce the computer's  BUS  (I/O CLK) speed and try again.  Refer to your computer's user's guide for instructions on how to adjust the BUS (I/O CLK) speed.  Third, contact the game manufacturer to ask for a joystick 


2.	Q:	I do not get any sound effects and/or music while running games, or, 
		The sounds produced by the games are very faint.
	A:	Run "PAS RESET" and then try running the games again.

3.	Q:	I have games that have already been installed before I installed the PAS16.  These games are still playing through the internal PC Speaker.
	A:  You need to re-select the sound card or re-install each game.  Please  refer to the guides for these games or contact the game manufactuers for assistance.

4.	Q: 	Links, The Golf Game, by Access, causes my computer to lock up.
	A:	Links defaults to IRQ 3 and I/O 220.  And the PAS16 defaults to IRQ5 and I/O 220.  Run SETBLAST.EXE  (which  came with Links) to change the defaults used by Links to match whichever settings used by the PAS16.

5.	Q:	Wing Commander II, by Origin, causes my computer to lock up or does not produce any digital audio.
	A:	First, make sure you have enabled speech in the WC II's INSTALL.EXE program.  Second, make sure you have expanded memory.  Third, if you use QEMM 6.0,  the "Stealth" option may distort sounds and lock up the computer.  Fourth, check the WC II's  WC2.CFG file.  At default, this file contains "v  a904 c27", where  "c" indicates Sound  Blaster driver, "2" indicates I/O 220, and "7" indicates IRQ 7.   Change these two digits to match the SB settings on the PAS16. 
	
6.	Q:	Falcon 3.0, by Spectrum Holobyte, does not play any radio voice messages and produces popping sounds.
	A:	Try running the computer in non-TURBO mode or by disabling the internal/external memory cache.  If the problem persists, please contact Spectrum Holobyte at (510) 522-1164 to request a software patch.  The current revision is D.  Any problems that you experience using this patch should be reported back to Spectrum Holobyte.

7.	Q:	I have some Disney Software games a that have problems with digital audio.
	A:	Please contact Disney Software at (818) 567-5340 to request a software patch.  Any problems that you experience using this patch should be reported back to Disney Software.

8.	Q:	I have some Lawrence Productions games that have problems with digital audio.
	A:	Please contac Lawrence Productions at (800) 421-4157 to request an updated CT-VOICE.DRV.  Any  problems that you experience using this patch should be reported back to Lawrence Productions.

9.	Q:	a.	LHX, by Electronic Arts, only plays sounds out of the internal pc Speaker.	 
		b.	Ultima V1, by Origin, produces distorted/noisy sound effects and music.
	A:	Please slow down the computer and try again.  This game does not abide by the sound requirements of the FM synthesizer chip, creating a problem when running in fast machines.

10.	Q:	Robin Hood, The Legend of the Long Bow, by Sierra, produces poor or no digital audio.
	A:	If the PAS16 is currently set at IRQ7, please select a different IRQ, for example IRQ5, and then try again.

11.	Q:	My game requires that I load the AdLib SOUND.COM or the Creative Labs SBSOUND.COM	 driver before starting up the game.
	A:	Media Vision has developed our own version of this driver.  It is currently available on our BBS.  The filename is FM.ZIP.

12.	Q:	Ultima Underworld does not produce any digital audio.  Music plays fine.
	A:	After you have finished installing the game and selected the Sound Blaster driver.  Run UWSOUND, which comes with Ultima Underworld, to select the IRQ setting to match with the PAS16's IRQ setting.

13.	Q:	I am having trouble running Interplay's Star Trek: The 25th Anniversary.  Can't select the Pro AudioSpectrum from the sound options.
	A:	The Pro AudioSpectrum option is for the PAS8.  The PAS8 uses a 2-operator FM synthesizer chip, and the PAS16 uses a 4-operator FM synthesizer.  The AdLib or SB sound options should work fine.

14.	Q:	After exiting Windows 3.1 and running Sierra's Mixed-Up Mother Goose, FM sounds are faint.  Cranking up volume helps but exposes background noise.
	A:	The PAS16's VPASD.386 driver will be updated to resolve this problem.

15.	Q:	I am having trouble running Microprose's Gunship 2000.
	A:	Microprose has developed new sound drivers which can be downloaded from our BBS.  The file name is GUNSHIP.ZIP which contains different driver files for different IRQ settings.  During GS2000's setup routine, select the AdLib driver.  Select the correct driver from this zip file to match with the IRQ setting set by MVSOUND.SYS.  The drivers assume DMA 3 on the PAS16 and PASPlus and DMA 1 on all other cards.

16.	Q:	I am having trouble running Kings Quest V on CD.  Music plays fine but there is no speech.
	A:	First, try "PAS RESET".  Second, make sure that the SB driver has been selected.  Third, make sure that the CD-ROM drivers have been properly loaded and that the CD-ROM drive is responding since KQ5 needs to access the CD-ROM drive to play speech.

17.	Q:	I am having trouble running Microprose's F1-17.  Sounds play at the wrong speed.
	A:	This game plays FM synthesized audio.  Make sure your Installation Disks have the current version of 1.2.  Add "T:1" to the end of the MVSOUND.SYS statement.  Refer to page 1-25 of the PAS16 User's Guide v1.1 for an explanation.

18.	Q:	Does Wolfenstein 3D work on PAS16?
	A:	Yes.  We have tested this game and found it to work properly on PAS16.  

19.	Q:	Does Sherlock Holmes on CD work on PAS16?
	A:	Yes.  We have tested this game and found it to work properly on PAS16.

******************************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.
