Setup May Detect Already Installed Hardware on MCA Computer

• Microsoft Windows 95

SYMPTOMS

When you re-install or upgrade the copy of Windows 95 on a Micro Channel Architecture (MCA) computer, one or more installed devices may be listed twice in Device Manager.

CAUSE

This problem can occur if you install a device manually using the Add New Hardware Wizard before you re-install or upgrade Windows 95. During Setup, a hardware detection routine runs to determine what devices are installed in the computer. On MCA computers, the hardware detection routine cannot determine which devices were already installed in Device Manager if the devices were installed manually.

RESOLUTION

To remove a duplicate device in Device Manager, 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 device, then click Remove. 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 device.

4. Click OK.

1. Click the Start button, point to Settings, then click Control Panel.

2. Double-click the Add New Hardware icon.

3. Click Next.

4. Verify that the Yes (Recommended) option button is selected, then click Next.

5. Click Next.
