M-Audio DMAN [45/52] Dos troubleshooting

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
