I have seen some documentation that says
you can switch Windows NT to run as a single CPU system with a
command line switch in the BOOT.INI file. I have not tested this as
I don't have a multi CPU computer. So I don't know if it really
works. To do this add a new line to the BOOT.INI (by coping one of
the existing lines) with the /onecpu option on the end as show
below:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation
Version 4.00"
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation
Version 4.00 One CPU" /onecpu
This
Knowledge base article is no longer relevant for users of
CitectSCADA version 6.10 and higher as Citect32.exe has been
modified into separate server and client components that can be
configured to run on separate CPUs and/or processes. These
modifications improve both the performance and stability of the
CitectSCADA runtime environment. For more information, see KB
Q4227.
