--------------------------------------------------------------

DESCRIPTION

When installing the AudioDrive drivers for the ESS 688, ESS 1688, ESS 
1788, and ESS 1888 sound cards, the address chosen by default is 220. 
In many systems, this port address is already in use; it is usually 
(but not exclusively) designated for the network adapter. This address, 
available or not, is added as a parameter for the device driver in the 
CONFIG.SYS file.

On the ESS 688 sound card this is not a problem, because this driver 
ignores the command line argument if the card is set to use a different 
port address. However, on the other cards, any of the following 
problems might occur:  

1. The card is not recognized by the system if the port address
   is being used by another device or if the card jumpers are set 
   to use another address (different from the address specified in the 
   CONFIG.SYS).

2. Errors occur during startup, stating that the drivers for 
   these cards (ESS*.*) cannot be loaded.

3. No multimedia sound because the card is not being recognized.

4. The system locks up on the ESS*.* drivers during startup.

RESOLUTION

The port address can be changed during installation, or with Selective 
Install after the installation is completed, as follows:

1. Open the OS/2 System folder.

2. Open the System Setup folder.

3. Open the Install/Remove folder.

4. Double click on Selective Install.

5. From the System Configuration window, select Multimedia Device 
   Support.

6. Select the driver for the sound card in the system from the 
   Supported Devices list and press the ADD button.

7. Press the Device Settings button under the list of 
   Devices in System to be Installed.

8. Select a different port address from the list 
   (start with 240) and click on OK.

9. Complete the selective install and restart the system.

Note: The plug-and-play ESS 1868 card does not have this problem.
