Third Port Detected with CMD PCI Dual Port IDE Controller

• Microsoft Windows 95

SYMPTOMS

When you are using a CMD PCI Dual Port IDE controller with at least one device on both the primary and secondary port, Device Manager displays a third port. The third port is displayed with an exclamation point inside a yellow circle.

CAUSE

The Plug and Play BIOS in your computer is erroneously reporting that a third port is present.

RESOLUTION

Windows 95 does not allocate any resources to the third port, and the existence of the third port in Device Manager should not cause any problems. However, if you want to disable the third port, follow these steps:

1. Use the right mouse button to click My Computer, then click Properties on the menu that appears.

2. Click the Device Manager tab.

3. Click the third port, then click Properties. Note that you may need to expand a branch of the hardware tree by double-clicking the branch, or by clicking the plus sign (+) to the left of the branch, before you can click the port.

4. Click the Original Configuration (Current) check box to clear it, then click OK.
