If your card encounters a conflict with a peripheral device, you may need to change its resource settings. If you are using Windows 95, run the Device Manager. If you are using Windows 3.1x, run the configuration utility that comes with your PnP configuration manager. For details, see "Resolving Hardware Conflicts" on page C-5.

Understanding the Installation
If your card encounters a conflict with a peripheral device, you
may need to change its resource settings.
If you are using
Windows 95, run the Device Manager.
If you are using
Windows 3.1x, run the configuration utility that comes with
your PnP configuration manager.
For details, see “Resolving
Hardware Conflicts” on page C-5.
When any resource setting
is changed, ensure that the environment variables (see
“Understanding the Environment Variables” on page A-3)
reflect the changes as well.
You can view your system
environment by typing
SET
at the DOS prompt.
Input/Output (I/O) Addresses
I/O addresses are communication areas used by your computer’s
central processor to distinguish among various peripheral devices
connected to your system when sending or receiving data.
Refer to “General Specifications” of the
Knowing Your Audio
Card
leaflet to find out which devices marked
§
are available on
your card.
