// For User Mgr:
|
|
// SoundBlasterPresent - SoundBlaster card present?
|
|
// AdLibPresent - AdLib card present?
|
|
// SoundMode - What device is used for sound effects
|
|
// (Use SM_SetSoundMode() to set)
|
|
// MusicMode - What device is used for music
|
|
// (Use SM_SetMusicMode() to set)

// For Cache Mgr:
|
|
// NeedsDigitized - load digitized sounds?
