  • Microsoft Windows NT Workstation version 3.51

SYMPTOMS

Windows NT may fail to shut down on some computers if the external cache options are not set correctly in the CMOS settings. If you do not have external cache on your motherboard, but the option is enabled in the CMOS settings, you may experience this problem.

RESOLUTION

To correct this problem, turn off your external cache option in CMOS by entering your computer's setup program.

MORE INFORMATION

Please notice that information contained in the SETUP.TXT file on the Windows NT 3.51 Server CD-ROM is misleading with regard to this problem. The SETUP.TXT file states: 

   Digital Venturis Systems with S3 Based Video
   --------------------------------------------
   The Digital Venturis line of computers with S3 based
   video may experience problems when attempting to
   restart. When selecting Shutdown/Restart, the
   system may freeze when attempting to reset the S3
   video. This is in no way detrimental to the system,
   simply restart via the reset button or power off the
   computer. This issue will be addressed in the near
   future.
This statement does not address the real issue: the problem occurs because the cache option is enabled in CMOS. Furthermore, current versions of the DEC Venturis have no reset button.
