The following article from the SCO Information Tools database should help 
with your problem.   I'm posting because I think this may be of general
interest.

Does SCO UNIX System V/386 Release 3.2.0 support Weitek coprocessors?

KEYWORDS:  weitek coprocessor math 3.2.0   unix

RELEASE:   SCO UNIX System V/386 Operating System Release 3.2.0

PROBLEM:   Does SCO UNIX System V/386 Release 3.2.0 support Weitek 
	   coprocessors?  Does the SCO XENIX System V Development 
	   System create code that utilizes them?

SOLUTION:  Yes, SCO UNIX does run binaries that were compiled to
	   use a Weitek coprocessor.  However, currently the SCO 
	   XENIX System V Development System does not have a way 
	   of creating code to use a Weitek.  It is a feature under 
	   consideration for a future release.  Thus, currently the 
	   Weitek coprocessor is only used by SCO UNIX if the program 
	   was a compiled by a product that will create Weitek code.

	   In order for the Weitek chip to be recognized, one file
	   needs to be edited in the following way:

	     In the file /etc/conf/sdevice.d/weitek, there should be
	     one line:

		  weitek N 1 0 0 ...

             Change the "N" (for no) to a "Y" (for yes).

	     Issue the following command to relink the UNIX kernel:

		  cd /etc/conf/cf.d
		  ./link_unix

             Answer "yes" when asked if this kernel should boot by 
	     default; answer "yes" again to rebuild the kernel
	     environment.

	     Reboot the machine; the Weitek chip will be recognized.
