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 Appendix D, “Resolving Conflicts”. When any resource setting is changed, ensure the environment variables (see “Understanding the Environment Variables” on page B-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.

Table B-1lists the default I/O address ranges assigned by the PnP system to various devices on your audio card.
