Thanks to those who responded to my question.

SUMMARY
=======
Gaussian 98W cannot use more than one processor but you can install
several copies of Gaussian in different directories, with different
scratch directories, and run them individually. The Windows Operating
System dynamically assigns jobs to the processors on the basis of
usage; each job should go to a different processor.
One person was concerned that this may violate the Gaussian license.
Doug Fox responded with an alternate method for starting multiple
Gaussian jobs (command line from a DOS prompt similar to Unix).
Although no definitive, I think it resolves this issue.
