The information in this article applies to:

  • Microsoft Windows NT Workstation versions 3.5 and 3.51
  • Microsoft Windows NT Server versions 3.5 and 3.51

SUMMARY

When you run 16-bit applications under Windows NT on an IBM Model 320 Microchannel computer with multiple processors, only the first processor is used. This is not true for the EISA version of the IBM Model 320. Because the second processor on MCA computers does not perform, some applications perform more slowly on a dual processor computer of this model than one with a single processor.
