OSCPRPRO - CONFLICTS WITH PRO AUDIOSPECTRUM AND PRINTER PORTS

=======================================================================
    Conflicts with Pro AudioSpectrum and Printer Ports in OS/2 Warp
=======================================================================

--------------------------------------------------------------

DESCRIPTION

* There might be conflicts with the Pro AudioSpectrum sound card when
  printing.

* Printing might be a problem only when a DOS or Windows program is
  running.

* Print jobs might disappear or the job might not print until the DOS
  or WIN-OS/2 session is closed.

RESOLUTION

Some changes have been made in the Pro AudioSpectrum 16 driver. See the
User's Guide to OS/2 V3.

The interrupt request (IRQ) of the card might not be specified in the 
MVPRODD.SYS statement of the CONFIG.SYS file. If the card has a jumper 
to set the IRQ, you might have to check the card manually for the IRQ 
setting.

There could be a conflict with the Sound Blaster emulation that is set 
up in the AUTOEXEC.BAT file or in the DOS settings under DOS_DEVICE. 
You do not set the Sound Blaster emulation IRQ in the CONFIG.SYS file.

The most likely problem is printing when Windows is running or with a 
specific DOS application. The software that comes with the Sound 
Blaster card sets up the MVSOUND.SYS driver to load from the 
AUTOEXEC.BAT file, where the IRQ is specified. If you find the driver 
is being loaded there, make sure it is not using IRQ7. If the system 
has 2 LPT ports, also make sure it is not using IRQ5.

If the driver is not specified in the AUTOEXEC.BAT file, check the 
settings of the suspect DOS or Windows program under DOS_DEVICE. See if
the driver is set there. This is the suggested location for the driver.
Make sure the IRQ setting does not conflict with another setting.

The Pro AudioSpectrum 16 card has either no jumpers, with the IRQ set 
in the CONFIG.SYS file, or has jumpers for setting the IRQ, and no IRQ 
specified in the CONFIG.SYS file. If the IRQ is specified in the 
CONFIG.SYS file, change the IRQ if it is conflicting with the printer 
port. If the card's jumper is set to the wrong IRQ, correct it.

The statement in the CONFIG.SYS file is:

   DEVICE=C:\MMOS2\MVPRODD.SYS /I:10 /D:5 /S:1,240,1,5 /N:PAS161$

One of the switches to look for is /S:. The syntax is:

   /S:x,xxx,x,x (enable,base_address,DMA_setting,IRQ_setting).

This is the Sound Blaster emulation line. Some systems do not have this
switch.

The other switch to check is /I:x, where x is the interrupt for the 
PAS-16 card.
