CardBus Card in Docking Station May Not Be Configured


The information in this article applies to:

  • Microsoft Windows 95 OEM Service Release, versions 2, 2.1


On certain laptop computers running Windows 95 OEM Service Release 2 (OSR2), when a CardBus card is inserted into a CardBus slot in the docking station the CardBus card may not be recognized or configured or may not function.


There is a hardware problem with some docking stations that prevents IRQs available to the PCI bus from being assigned to CardBus devices in the docking station.


This issue is resolved by the following updated file for Windows 95 and OSR2, and later versions of this file:

   CBSS.VXD  version 4.00.1112  dated 9/16/96  15,737 bytes
   PCI.VXD   version 4.00.1112  dated 9/16/96  42,271 bytes 


Microsoft has confirmed this to be a problem with certain computers running Microsoft Windows 95 OEM Service Release 2. A software fix to this problem is in development, but has not been regression tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Technical Support for additional information about the availability of this fix.

This issue is resolved in Microsoft Windows 98.
