Driver Parameters In CONFIG.SYS File
------------------------------------
The following parameters are used for the Sound Blaster series of drivers:

DEVICE=C:\MMOS2\SBxxD2.SYS DEVNO [DMA] [HDMA] INT IOADDR BUFSIZE [MPUADDR] /N:DRVNAME

where

DEVNO is the audio device number (default: 1)

DMA is the 8-bit DMA channel to be used by the audio card 
(applicable only for Sound Blaster Pro/Pro2, 16, and AWE32)
Valid values: 0, 1, 3 (SB Pro, Pro MCV, SB16, AWE32)

HDMA is the 16-bit DMA channel to be used by Sound Blaster 16 & AWE32
(applicable only for Sound Blaster 16 and AWE32)
Valid values: 5, 6, 7 (SB16, AWE32)

INT is the interrupt level to be used by the audio card
Valid values: 2, 5, 7, 10 (SB Pro, 16, AWE32)
              3, 5, 7     (SB Pro MCV)
              2, 3, 5, 7  (SB)
              3, 5, 7     (SB MCV)
                    
IOADDR is the I/O address of the audio card (default: 220 hex)
Valid values: 220, 240, 260, 280 hex

BUFSIZE is the buffer size in kilobytes (default: 4 for Sound Blaster,
Sound Blaster Pro/Pro2; 8 for Sound Blaster 16, Sound Blaster AWE32)
Valid value: 2-64 (even number only)

MPUADDR is the MPU-401 interface base address (default: 330 hex, 
applicable only for Sound Blaster 16 and Sound Blaster AWE32)
Valid values: 300, 330 hex

DRVNAME is the device driver name used by MMPM/2 subsystems


Increasing the Number of Allowable Audio Instances
--------------------------------------------------
You can increase the total number of audio applications that can be 
opened at the same time by modifying the following line in your 
CONFIG.SYS file:

DEVICE=C:\MMOS2\SSMDD.SYS /S:64 /P:64

This instructs the MMPM/2 subsystems to allow a maximum of 64 processes 
to be started at one time.

                                                                    [AC02241995]
