B-2 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 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-1 lists the default I/O address ranges assigned by the PnP
system to various devices on your audio card.
