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.
