DOS Driver Installation

Windows 3.1x Driver Installation

Wavetable Driver for DOS based Games (ES1688 only)

Your sound card supports a universal wavetable daughterboard upgrade. If you have attached a wavetable daughterboard and you cannot hear background music or sound effects from the wavetable (usually General MIDI standard) synthesis chip, then quite possibly the game you are using does not include a driver for wavetable synthesis (an example = "Doom2"). In this case you need to enable the Wavetable Driver included on diskette # 1/1. Install as follows..

Windows '95 Drivers

Drivers for Windows '95 are already embedded in the Windows '95 application software program therefore driver diskettes are not required if running this program. ESS688/1688 User Manual 5
