and Answers.
QUESTIONS & ANSWERS:
*******************************INSTALLATION********************************
1. Q: Do I have to change any switches or jumpers before I install the
PAS?
A: The default settings will work in most computers. Only try with
different DMA and IRQ settings if you experience any problems.
Whenever changing the settings on the PAS, make sure you make the
same changes in the MVSOUND.SYS statement, in CONFIG.SYS.
2. Q: What is the MVSOUND.SYS driver for?
A: You must have "DEVICE = C:\PROAUDIO\MVSOUND.SYS D:X Q:X V:X" in
the CONFIG.SYS file. The first two X's correspond to the DMA
channel and IRQ settings. The third X in "V:X" represents the
initial volume level, a value between 0 and 40, where 40 is the
maximum volume level. This driver resets the mixers and the
volume settings on the PAS. Without this driver, none of your
Adlib games will play sounds.
3. Q: I have tried with all settings and PASTEST.EXE still fails.
A: First, PASTEST.EXE may need to be run twice in a row. Second,
reduce the system to a generic CONFIG.SYS and AUTOEXEC.BAT to
eliminate possible software conflicts. Third, remove all
unnecessary peripheral boards (scanner, tape controller, network
cards, etc.) in the system to eliminate possible hardware
conflicts. Fourth, in most computers, it will accurately report
if there are conflicts; however, in some 486/33 computers, it may
not be accurate. If you have already tried everything and
PASTEST still fails, go on and run AudioLnk.
4. Q: After I have installed the PAS and connected the PC Speaker cable
to the PAS, I do not hear any PC Speaker sounds in my 486/33.
A: Some 486/33 computers do not allow the PAS to implement PC
Speaker sounds. Therefore, leave the PC Speaker cable on the
motherboard so that these sounds will be produced by the
motherboard and played through the internal PC Speaker.
*********************************AUDIOLNK**********************************
5. Q: a. When I run AudioLnk to play MIDI, it does not produce any
sound.
b. When I run AudioLnk to play WAV, it does not produce any
sound.
c. When I run AudioLnk to play WAV, it plays the same sound
over and over like a broken record.
A: a. If MIDI does not play, it is a possible IRQ conflict.
b. If WAV does not play, it is a possible DMA conflict.
c. If WAV plays like a broken record, it is a possible IRQ
conflict.
First, you must have the sound drivers (TAPIMV/VMP/AUDIOMAT)
loaded prior to running AudioLnk. Refer to the AudioMate Section
in the PAS User's Guide. Second, select a different DMA/IRQ and
try again. Whenever changing the settings on the PAS, make sure
you make the same changes in the MVSOUND.SYS statement, in
CONFIG.SYS. Third, reduce the computer's bus (I/O CLK) speed to
10MHz or less and try again.
6. Q: When I run AudioLnk to play CD-Audio, the CD-ROM drive's light
does not come on and I do not hear any sound.
A: You may need to press F3 twice in a row.
7. Q: There is a lot of noise in the microphone recordings.
A: First, make sure that the microphone has 600-ohm impedance (or
higher). Second, mount the microphone on a stand instead of
holding in your hand. Third, use headphones instead of external
speakers/amplifiers to eliminate the possibility of feedback
which can cause distortion or noise.
8. Q: Running PAS.EXE to adjust the mixer and volume settings before
going into AudioLnk does not make any difference at all.
A: First, AudioLnk ignores the settings made in PAS.EXE. Second,
once inside AudioLnk you can adjust the mixer and volume settings
by pressing F4 to activate the Recording Menu and then F9 to
access the Mixer Control Panel.
********************************SP SPECTRUM********************************
9. Q: When I bring up Sp Spectrum (by running SEQ.BAT), TAPIMV.COM
reports that it cannot find the interrupt.
A: Edit the SEQ.BAT to add the "/IRQ:X" switch to the end of the
TAPIMV.COM statement, where X is the IRQ setting, and try again.
10. Q: When I run Sp Spectrum, I do not hear any sound when it is
supposed to be playing.
A: First, make sure the port in Sp Spectrum is set to 2 to use the
FM synthesizer chips on the PAS. Port 1 is for playing through
an external MIDI equipment. Second, select a different IRQ and
try again. Whenever changing the settings on the PAS, make sure
you make the same changes in the MVSOUND.SYS statement, in
CONFIG.SYS. Third, reduce the computer's bus (I/O CLK) speed to
10MHz or less and try again.
11. Q: Page 18 of the Sp Spectrum Section in the PAS User's Guide refers
to the Tutorial file which I cannot find.
A: The current version of the PAS disks has this file. Please send
in your PAS disks to the attention of Customer Support. Include
your name, address, phone number and a note to request for an
update.
********************MPU-401 AND SOUND BLASTER EMULATION********************
12. Q: a. Does the PAS support MPU-401?
b. Does the PAS support SB?
A: a. No. The MIDI Interface chip on the PAS is the Yamaha 3802
MIDI controller and not the Roland MPU-401 MIDI Interface
chip.
b. No. The method used on the PAS to record and play back is
different on the existing SB card.
Note: Media Vision has developed an emulation program which
enables the PAS to emulate the MPU-401 in "DUMB mode" and
the SB to work with most SB games. Please note that this
program requires a 386SX or better and will work in DOS and
Windows 3.0. This emulation program is called SB2MV.ZIP and
is located in the ZIP files area of this BBS.
*********************************GAMES*************************************
13. Q: My PAS is set to DMA 3 and IRQ 5. I hear music but I don't hear
any sounds when running Sierra games that support the PAS.
A: The PAS driver in your Sierra games require that the PAS is set
for DMA 1. Some Sierra games also require IRQ 7. Sierra is
working on updating the PAS driver to allow DMA 1/2/3 and IRQ
3/5/6/7 to be selected. Please contact Sierra for the update.
14. Q: I have games/software that provide drivers for the SB and AdLib.
Which driver should I select?
A: The PAS is 100 percent AdLib compatible and will work with any
package that provides driver for AdLib. If the package does not
support digital audio, then the AdLib driver or SB driver can be
selected. Otherwise, if the package does support digital audio
with the SB driver, please refer to the "MPU-401 and Sound
Blaster Emulation" section above.
15. Q: Does the PAS make my game sound better than my AdLib board?
A: PAS.EXE is a utility that allows you to adjust the mixer, volume
settings, bass, treble, loudness, enhanced stereo (will make a
mono signal simulate stereo), and realsound (to improve PC
speaker sounds).
16. Q: Sometimes when I play a game that supports AdLib, I only hear
sound out of one speaker.
A: There are two ways to run PAS.EXE. The first way is to run "PAS
RESET" to reset the mixer. The second way is "PAS *" to bring up
the Mixer Control Panel on screen. Press F1 to get help, then F4
to reset the mixer.
17. Q: The joystick does not work at all or does not work properly when
using the PAS'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 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 driver
that works on fast machines.
*****************************SCSI INTERFACE********************************
18. Q: Which CD-ROM drives can I use with the PAS?
A: See CD-ROM Drives Support List above. The PAS has a SCSI
interface which only allows it to control SCSI devices. Please
contact Media Vision Sales for the SCSI Cable/Driver Kit
(Internal/External).
19. Q: Do I have to use the PAS SCSI interface to control my CD-ROM
drive which has its own controller?
A: If your CD-ROM drive is SCSI, you can use its own controller or
the PAS SCSI interface.
20. Q: Can I use the PAS to control other SCSI devices?
A: Yes. Trantor Systems is currently selling SCSI drivers for the
PAS for a variety of SCSI devices (hard disks, removable media,
optical, etc.). Please contact Trantor Systems for the PAS
driver set at (510) 770-1400. The price for the driver set is
$59.00.
21. Q: Will the SCSI interface on the PAS conflict with another SCSI
controller if they are both installed in the same computer?
A: They should work fine together. Make sure that the drive ID's
for the SCSI devices are different.
************************CD-ROM DRIVE INSTALLATION**************************
22. 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 PAS to control the CD-ROM drive, you need to use
our TSLCDR.SYS driver; 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 PAS. Third, make sure the red painted edge of
the cable is closest to the 4-pin connector on the PAS at J6.
Fourth, make sure the terminator is connected securely to the
back of the CD-ROM drive. Try both with and without the
terminator. Fifth, reduce the system to a generic CONFIG.SYS and
AUTOEXEC.BAT. Sixth, reduce the computer's bus (I/O CLK) speed
to 10MHz or less. Seventh, if there is a co-resident Thunder
Board, make sure Switch 4 (FM synthesizer switch) on the TB is
set of OFF.
23. Q: I get the error "No devices respond on this SCSI host adapter".
A: First, check the internal, flat ribbon SCSI cable to make sure it
is properly connected to the back of the CD-ROM drive. Second,
make sure the terminator is connected securely to the back of the
CD-ROM drive. Try both with and without the terminator. Third,
make sure you have inserted the computer's power plug into the
CD-ROM drive connector and pushed it firmly into place.
24. 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 the TSLCDR.SYS and MSCDEX.EXE statements
from "MVCD001" to "TSLCD". Second, make sure that the device
names in both of these statements match.
25. Q: MSCDEX.EXE issues 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". We
will make an announcement in the BBS Newsletter when the new
version of MSCDEX.EXE is available, which will not require
SETVER.EXE when using MS DOS 5.0.
26. Q: I cannot use the CD-ROM drive.
A: First, refer to the questions listed above. Second, make sure
the MSCDEX.EXE statement precedes any menu, DOS Shell, PCTOOLs,
or any desktop manager statements in AUTOEXEC.BAT to ensure that
the driver has been properly loaded.
27. Q: I get the error "Invalid drive specification" when I type the
drive letter assigned to the CD-ROM drive.
A: First, make sure you have "LASTDRIVE = X" in the CONFIG.SYS,
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. If not, refer to the
questions above.
28. Q: I get the error "CDR 101: Drive not ready".
A: First, check the internal, flat ribbon SCSI cable to make sure it
is properly connected. Second, make sure the terminator is
connected securely to the back of the CD-ROM drive. Try both
with and without the terminator.
29. Q: a. I get the error "CDR 103: CD-ROM not High-Sierra or ISO-9660
Format Reading Drive X. Abort, Retry or Ignore?"
b. My CD-ROM drive fails at random.
A: First, check if the LASTDRIVE statement and TSLCDR.SYS driver are
loaded before a hard disk driver and/or a memory manager. If so,
load the hard disk driver and/or memory manager first. Second,
refer to the question above.
