2.2 Software Driver Installation

DOS Driver Installation

• Insert the Drivers disk # 1/2 into your floppy drive, log onto that drive and type INSTALL at the DOS prompt.
• The sound card driver installation program will appear. Follow the on-screen prompts to configure the sound card for your system.
• After setup, you should sound test the sound card by clicking on the TEST button. If there are any problems, check your I/O address, IRQ and DMA settings.
• Once you are satisfied with your settings, click on the OK button at the bottom of your screen and the DOS driver installation program will finish setting up your system by modifying your AUTOEXEC.BAT and CONFIG.SYS files and copying appropriate driver software to your system.

Windows 3.1x Driver Installation

• After entering Windows 3.1 or higher, choose Run from the File Menu of the Program Manager.
• Place the Drivers disk # 1/2 into your floppy drive. In the Run dialog box, type the letter of the drive and setup (for example A:\setup), then click the OK button.
• When the AudioRack Setup window appears, click the Driver Installation button, then click the Automatic Board Configuration button.
• After that, click the Restart Windows button for installing the Windows driver and the Windows system will be updated automatically.

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..

• Install DOS drivers as stated above.
• The process of DOS driver installation will create a directory called PCAUDIO. Go to this directory on your specific drive (usually C:\PCAUDIO\) by typing CD PCAUDIO at the C:\ prompt.
• Type EN1688 - This will install the wavetable driver.

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
