DOS Troubleshooting

When you run DMAN DOS-based diagnostics application, each
test passes or fails on the basis of meeting two criteria. Each test
checks that DMAN can be contacted at the parameter in question,
and also pauses for a period of time to ensure that no IRQ, DMA
request, etc. is initiated by a device other than DMAN. Failing to
reach DMAN or detecting the signal from another device will
cause the test to fail.

To fix communication conflicts, you may need to edit the
initialization file CS4232.INI which resides in the same directory
as the other DMAN DOS applications. This is usually
C:\MIDIMAN\DMAN if you chose the default during
installation. CS4232.INI is a text file that may be edited manually
using a text editor such as DOS’s EDIT.COM or Windows’
NOTEPAD.EXE. If you change any parameters in the CS4232.INI
file you will need to run CS4232C.EXE located in that same
directory. Running CS4232C.EXE will reconfigure DMAN to the
changed settings.

IMPORTANT

: The CS4232.INI file only affects non-PnP

systems. Systems with PnP ignore the CS4232.INI file and
automatically configure the devices in the system to what it
believes are available addresses, IRQs, and DMA channels. In
this PnP case, you will have better luck modifying the settings
of the non-PnP (older ISA cards) devices to not clash with the
DMAN settings.

The following settings may be edited in the CS4232.INI file:

SndBlstr Port Address: If the SndBlstr (Sound Blaster) test fails,
you may have a port address conflict. Usually this will only
happen if another Sound Blaster compatible card is installed in
the computer. Change the SB Port Address setting indicated by
the "SbIO=" line in the [PNP] section. Set it to either 220, 230 or
240.

SndBlstr Interrupt: If the SndBlstr (Sound Blaster) test fails, you
may have an interrupt (IRQ) conflict. Change the line "WSSInt="
in the [PNP] section in the CS4232.INI file. Set it to 5,7,9,11,12 or
15.

SndBlstr DMA Channel Conflict: If the SndBlstr (Sound Blaster)
fails, you may have a DMA playback channel conflict. Change
the DMA playback channel setting in the CS4232.INI file. This is
