CardBus PCMCIA Controller Disabled After Second Boot

• Microsoft Windows 95 OEM Service Release versions 2, 2.1

SYMPTOMS

After the second boot with a CardBus PCMCIA controller installed in your computer, Device Manager may display a red "X" for the two PCMCIA sockets (meaning they are disabled).

CAUSE

CardBus controllers are dynamically enumerated during the first boot after installation even though they are installed disabled. On the second boot, Windows 95 recognizes that the device is disabled and reports this in Device Manager.

RESOLUTION

Enable the PCMCIA controller. To do this, follow these steps:

1. In Control Panel, double-click System.

2. Click the PCMCIA controller, and then click Properties.

3. In the Device Usage box, click the "(Current)" check box to select it.

4. Click OK.

5. Click Close. When you are prompted to restart the computer, do so.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

CardBus controllers are PCI devices that are dynamically enumerated by the PCI enumerator. The drivers load during Setup, ignoring the Disable bit in the registry. During the second boot, Windows Configuration Manager recognizes the registry entry indicating that the device is disabled, displays a red "X" in Device Manager, and does not start the controller. CardBus controllers must be explicitly enabled to invoke the PCMCIA Wizard on the second boot.
