Carmen San Diego Game Interrupted After Digitized Sound Played (98316)

SUMMARY

The MS-DOS-based game "Where in the World Is Carmen San Diego" may work with interruptions when running with Windows. In Windows enhanced mode, the game can run from MS-DOS Prompt in a full screen with Sound Blaster emulation from Windows Sound System; but in some cases, you may need to turn off the virtual interrupt request line (IRQ) for the game to run properly.

MORE INFORMATION

The MS-DOS-based game, "Carmen San Diego USA/Deluxe and World/Deluxe Versions" from Broderbund can run in Windows enhance mode from MS-DOS Prompt in a full screen with Sound Blaster support after you configure the Windows Sound System for Sound Blaster emulation. Sound Blaster emulation will allow the game to play digitized sounds while you run the game. However, in some cases the game may be interrupted after a digitized sound is played, and you may have to press the ESC key to continue.

When this happens, you will need to turn off the virtual hard drive IRQ from Windows, which is on by default for AT-class machines. Turning this off allows Windows to terminate the hard drive interrupt without having to go to the read-only memory (ROM). To turn off the virtual hard drive IRQ, make the following modification to your SYSTEM.INI file:

From MS-DOS, open the SYSTEM.INI file in a text editor. The SYSTEM.INI file should be located in your Windows directory.
Locate the [386enh] section and add or modify the following line:
```
      VirtualHDIRQ=False
						
```
Save the changes, exit the editor, and run Windows in enhanced mode.
From Windows enhanced mode, start MS-DOS Prompt and run the game.

NOTE: Disabling VirtualHDIRQ may degrade the performance of Windows in 386 enhanced mode.
