Games Configuration Program Saves Previous Settings (96495)

SUMMARY

When you run the Games Configuration icon to configure Windows Sound System to support MS-DOS-based games to run with Windows; the previous board settings are recorded in the [sndsys.drv] section of the SYSTEM.INI file.

MORE INFORMATION

For MS-DOS-based games to run in Windows, the Windows Sound System hardware has to be reconfigured. The Games Configuration program allows you to select a different IRQ and Port address. Set the Windows Sound System board to be compatible with most MS-DOS-based games or programs that use sound. The IRQ choices are 7 or 9, and the Port or I/O addresses are 210h, 220h, 230h, 240h, 250h, and 260h. After you carefully select the new settings you need to restart Windows so that the new settings take effect. The old settings are recorded in the [sndsys.drv] section of the SYSTEM.INI file as follows:

previousIRQ=11
previousDMADAC=0
previousDMAADC=0
previousDMABufferSize=0

The sample settings above are from a default Windows Sound System installation.

Notice that there is no entry for the previous I/O address. This is because the port address gets remaped in memory and the I/O address being used by Windows Sound System is actually the one set during installation.
