Upgrading WinNT 3.51 to 4.0 w/ NCR/Symbios Logic Controller

RESOLUTION

Prior to upgrading, use the Windows NT Setup program to remove the Symbios Logic PCI (53c8XX) SCSI adapter driver and add the NCR PCI (53c810) adapter driver included with the Microsoft Windows NT 3.51 compact disc. This process installs the Microsoft Ncrc810.sys driver. Then perform the Windows NT 4.0 upgrade as normal.

Some systems will not function with the Ncrc810.sys driver. Owners of those systems that can't use the Microsoft provided Ncrc810.sys driver, or users that have upgraded Windows NT with the Symcxx.sys driver in place, should contact Symbios Logic for technical support. Symbios Logic's technical support can be reached at (719) 533-7230.
