This section explains how to use the audio utilities provided with your
computer.  If you need to reconfigure the audio adapter, refer to the
"Audio Adapter Appendix."

Changing Audio Software Settings

If you change the settings of the audio adapter jumpers that control the
audio port address, interrupt, or DMA channel setting, you must update
the SET BLASTER command line.

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 the SBP-MIX utility.  The default
command line is:

   "SET BLASTER=A220 I7 D1 T4"

The default command sets the audio port to 220H (A220), sets the audio
interrupts to 7 (17), 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 interrupt, or audio DMA channel,
use a text 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.
