Upgrading to Windows NT 4.0 Service Packs 4 or 5 if you use Digi Serial I/O

We produce Patch Sets for mvBase that offer resolutions to known problems. Microsoft Corporation does the same for Windows NT in the form of Service Packs. Both Pick and Microsoft recommend that you always keep up to date with the most recent Patch Sets (Pick) or Service Packs (MS).

If you are upgrading your Windows NT Server or Workstation to NT Service Pack 4 or 5 and you use Digi ISA/PCI AccelePort C/X C/CON 8 & 16 serial I/O then you should follow this recommendation from Digi:

The Digi C/X driver should be installed after Windows NT Service Pack 4 or 5 has been installed. If the driver is already installed, remove it, perform the upgrade to Service Pack 4 or 5 and then reinstall it.

Support is aware of a few incidents where customers have not un-installed/re-installed the driver when upgrading to SP4/5 and the mvBase workstation would not start.

NOTE: If you are going to have to re-install the Digi driver, our Engineering staff strongly recommends that you install the most recent version from Digi.

As of December 1999 this is the 'W' driver. It has been certified for use with mvBase. It can be obtained from Digi's web site at:
