SYMPTOMS
When you install FastBack Plus for Windows, version 1.0, using Windows for Workgroups, the following warning message appears:

SYSTEM.INI Includes Non-Standard Drivers!

Some other application (possibly a backup product from a different manufacturer) has modified your SYSTEM.INI file to use incompatible, non-standard VDMAD and/or VFD drivers. These drivers may cause failures in many applications, including FastBack Plus Windows.

Install will first backup your SYSTEM.INI as SYSTEM.FBP, and then restore it to use the Microsoft standard drivers. This change is necessary for correct operation.

FastBack Plus Windows continues installation and changes the virtual DMA device entry in the SYSTEM.INI file to device=*VDMAD.



CAUSE
The warning message is the result of a change in the name of the virtual DMA device driver in Windows for Workgroups. Windows versions 3.0 and 3.1 specify this device in the [386Enh] section of the SYSTEM.INI file as follows: device=*VDMAD With Windows for Workgroups, this entry is changed to: device=VDMAD.386



WORKAROUND
To allow Windows for Workgroups to function properly, you need to restore the default Windows for Workgroups entry. Use any text editor (such as Notepad) and change the virtual DMA device entry in the [386Enh] section of the SYSTEM.INI file to: device=VDMAD.386



STATUS
Fifth Generation Systems has confirmed that FastBack Plus Windows operates properly with the default Windows for Workgroups setting for the virtual DMA device driver. Future versions of FastBack Plus Windows should recognize this change with Windows for Workgroups.

FastBack Plus Windows is manufactured by Fifth Generation Systems, Inc., a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
