OSPRWPRO - CONFLICTS BETWEEN PRO AUDIO SPECTRUM AND PRINTER PORTS
IN OS/2 WARP
01/13/95
================================================================
CONFLICTS BETWEEN PRO AUDIO SPECTRUM AND PRINTER PORTS IN WARP
================================================================
Please Read Entire Document for Full Explanation of Procedures
----------------------------------------------------------------
SYMPTOMS:
1. There may be conflicts with the sound card when printing.
2. Printing may be a problem only when a DOS or Windows program is
running.
3. Print jobs may disappear or the job may not print until the DOS
or Win/OS2 session is closed.
RESOLUTION:
There have been some changes in the PAS-16 driver. See the
User'S Guide to OS/2 V3.
The IRQ of the card may not be specified in the MVPRODD.SYS line in
the CONFIG.SYS. If the card has a jumper to set the IRQ,
you may have to check the card manually for the IRQ setting.
You do not set the SoundBlaster emulation IRQ in CONFIG.SYS. There
could be a conflict with the SoundBlaster emulation that is set up in
AUTOEXEC.BAT or the DOS settings under DOS_DEVICE.
The most likely problem is printing when Windows is running or a
specific DOS app. When setting up the SoundBlaster emulation of the
PAS-16, the software that comes with the card sets up the driver to
load in AUTOEXEC.BAT, where the IRQ is specified. If you find the
driver (MVSOUND.SYS) is being loaded there, make sure it is not using
IRQ7. If the system has two LPT ports, make sure that it is also not
using IRQ5.
If the driver is not found in AUTOEXEC.BAT, 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. Check the
IRQ setting in the driver to verify that it is not set for a
conflicting IRQ.
The PAS-16 card has either no jumpers and has the IRQ set in
CONFIG.SYS, or jumpers on the card for setting the IRQ and no IRQ
specified in the CONFIG.SYS. If the IRQ is specified in CONFIG.SYS,
change the IRQ if it is conflicting with the printer port. If the card
is jumpered to the wrong IRQ, change the jumper to set it to use a
different IRQ.
The line in CONFIG.SYS 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,IRQ).
This is the SoundBlaster 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.
