KB106665 - Example SYSTEM.INI Configuration Lines for Sound System

SUMMARY

The following information is an example of the [SNDSYS.DRV] section of the SYSTEM.INI file for the Windows Sound System. The explanation describes which lines determine the DMA, Interrupt, and I/O address of the Windows Sound System card:

   [SNDSYS.DRV]
   DMABufferSize=32
   EnableAutoAcquireOPL3=1
   Msft Hardware=1
   Msft Support=1
   Auto Select=1
   Midi Play=1
   DMA 0=1
   DMA 1=1
   DMA 3=1
   Default DMA=0
   I/O 530=1
   I/O 604=1
   I/O E80=1
   I/O F40=1
   Default I/O=530
   IRQ 7=1
   IRQ 9=1
   IRQ 10=1
   IRQ 11=1
   Default IRQ=7
   OldMSDOSGameCompatibility=False
   DMADAC=0
   DMAADC=0
   Interrupt=10
   IOAddress=530

The DMADAC and the DMAADC lines determine the DMA that Windows Sound System uses. The Interrupt and IOAddress lines determine the interrupt and I/O address of the board.
