MPC Audio Adapter  (250-1099)    Software Drivers      Faxback Doc. # 2720

If you change the audio adapter jumpers that control the audio port
address, interrupt, or DMA channel setting, you will need to update the
audio drivers and the SET BLASTER command.

CHANGING THE SET BLASTER COMMAND LINE

The SET BLASTER command line is included in your AUTOEXEC.BAT file.  This
command line enables you to control the volume of audio sources from the
MS-DOS command line with SBP-MIX.  The default command line is as follows:

SET BLASTER=A220 I7 D1 T4

The default command sets the audio port to 220H (A220), sets the audio
interrupt to 7 (I7), and sets the audio DMA channel to 1 (D1).  T4 sets
the adapter type.  Do not change the adapter type.

If you change the audio adapter's audio port, audio interrupt, or audio
DMA channel, use a test editor to open the AUTOEXEC.BAT file and update
the A,I, and D command line options to reflect the new settings.  Restart
the computer after changing the SET BLASTER command line.

CHANGING THE AUDIO DRIVER SETTINGS

To change the settings of the audio driver.

1.  From the Window Program Manager, open the Main group and double click
    on the Windows Control Panel.

2.  Double click on Drivers.  Select Voyetra Super Sapi FM Driver and
    select Setup.  Select 220 or 240 to match the audio port address of
    your audio adapter.

CAUTION:  Do not select 260 or 280 as the port address.  These settings
          are invalid for our audio adapter.

After you make a change to a drive r setting, Windows prompts you to save
the setting by exiting and restarting.  If you need to update another
driver, select Don't Restart Now.  If you do not need to make additional
changes, select Restart Now to update the audio drivers with the new
settings.

3.  Click on Creative Sound Blaster Pro Auxiliary Audio (B).  Then, select
    Setup.  Select 220 or 240 to match the audio port address of the audio
    adapter.

After you make a change to a driver setting, Windows prompts you to save the
settings by exiting and restarting.  If you need to update another driver,
select Don't Restart Now.  If you do not need to make additional changes
select Restart Now to update the audio drivers with the new settings.

4.  Click on Creative Sound blaster Pro Waveform and MIDI.  Then, click on
    Setup.  Select 220 or 240 to match the audio port address of the audio
    adapter.  Set the interrupt (INT) to 2,5,7, or 10 to match the audio
    DMA channel selected for your adapter.

After you make a change to a driver setting, Windows prompts you to save
the settings by exiting and restarting.  If you need to update another
driver, select Don't Restart Now.  IF you do not need to make additional
changes, select Restart Now to update the audio drivers with the new
settings.
