I may be wrong, but as I remember, the way a CPU without co-processor
works is this: if there appears a floating point instruction and there
is no FPU, the CPU generates that ``floating exception'' to leave the
possibility to the software to get around that.
For example, FreeBSD has a built-in FPU emulator that works if the
FPU isn't present.
Maybe that top just reports those exceptions as they appear and this
isn't a bug but a feature :-) ?
Can you get your hand on an 387 FPU? Perhaps you can put it into your
machine and try again - then those exceptions shouldn't appear.
I don't have a 386 here available, so I can't try it out, sorry.
Bye,
Martin
