The information in this article applies to:


 * Microsoft Windows 95
 * Microsoft Windows 95 OEM Service Release, version 2.0

SYMPTOMS
When you use a Zoomed Video (ZV) PC Card with Windows 95, the card is not recognized correctly.

In Microsoft Windows 95 OEM Service Release version 2 (OSR2), ZV PC Card devices are recognized, but are not configured. The driver is loaded, but is never asked to start. Device Manager indicates that the device has a problem with a Code 7.

CAUSE
Windows 95 and OSR2 do not include support for Zoomed Video.

Most of the support to enable a ZV PC Card was added to OSR2, but was not enabled when OSR2 was shipped. As a result, the logical configurations for these devices get filtered out and the device cannot be started.

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

  PCCARD.VXD  version 4.00.1112  dated 11/1/96  78,553 bytes

NOTE: This update has been created for Microsoft Windows 95 OSR2 to enable the configuration of ZV PC Card devices. It is up to vendors to test this update with their ZV PC Cards on OSR2.

STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 95 OEM Service Release 2 (OSR2). An update to address this problem is now available, but is not fully regression tested and should be applied only to computers experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft does not recommend implementing this update at this time. Contact Microsoft Technical Support for additional information about the availability of this update.

This issue is resolved in Microsoft Windows 98.
