I'm 99% sure you need either to upgrade to MCL 2.0.1 or install the
"Centris-without-FPU" patch.  Both the upgrade and that patch are
available on Digitool's FTP server via anonymous FTP.  (Or if you
prefer, you can upgrade through APDA for $25 and get a new CD-ROM
of MCL 2.0.1.)

The reason the problem doesn't show up on the Duo 230 is that its
CPU is a 68030.  The FPU problem was that originally there were
no models of 68040 without an FPU, and so the code assumed that
if there was a 68040 there was also an FPU.  The 68LC040 changed
that assumption.
