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.

MORE INFORMATION
================
