SYMPTOMS

When you use Device Manager to view the input/output (I/O) addresses of devices in your computer, some I/O addresses may be used by Alias Of <device>, where <device> is the name of a device that is currently in your computer.

CAUSE

This behavior can occur if your computer contains unused I/O addresses.

STATUS

This behavior is by design.

MORE INFORMATION

In Microsoft Windows 95, all unused I/O addresses are assigned to In Use By Unknown Device. In Windows 98, all unused I/O addresses are assigned to aliases of devices that are currently in your computer. I/O addresses that are assigned to a device alias can be used by new devices you add to your computer.
