Article ID: Q132858

The information in this article applies to:

Microsoft Windows NT Workstation version 3.51
Microsoft Windows NT Server version 3.51

SYMPTOMS

After you install Windows NT 3.51 on a Motorola PowerStack computer that has 16 megabytes (MB) of memory and a Cirrus video adapter, Windows NT 3.51 stops responding (hangs) during startup.

CAUSE

This problem occurs due to low system memory. The Cirrus miniport driver maps 16 MB of virtual memory (frame buffer) during startup and does not release it.

RESOLUTION

To correct this problem, install the latest U.S. Service Pack for Windows NT version 3.51.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 3.51. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
