• More information here

• Installed with Windows 98 UBCD

• CrystalClear SoundFusion

  • Supports SB Pro (3.02)  220h, IRQ 5, DMA 1. Setting can not be changed. 

  • Supports Adlib from DOS. OK, but a plays to fast. AdLib sounds better then SB.

  • Must have CWCDOS.EXE to support FM/OPL and DSP in DOS

• It supports SB and Adlib in Windows 98SE, plus General Midi. The General Midi from Windows is very good.

• Must use old audio drivers to get DOS support.  The newer version adds DirectX 8 support, but removes DOS drivers and SB compatibility in Windows.

• All in all this is an OK machine for DOS gaming. 

  • Minus for the poor OPL (adlib/SB) support.

  • Plus for a good screen with hardware scales 320x200 games to fullscreen.

  • The best way to play DOS games on this machine is from Windows because you General Midi support, and therefor do not rely on the bad OPL implementation.

  • Demos usually do not use MIDI/OPL so they run best from DOS.

• Very good for Windows 98 gaming - because it has an S3 Savage with 8MB ram. Good for DirectX games.
