The Phoenix AT BIOS that I have experience with has a bug in the coprocessor
detect routine.  The coprocessor detected line down at the bottom just says
whether or not it sees a coprocessor.  But there's a bug in the routine, so
it never sees it.  Try running Norton's SI, or any program that must have a
coprocessor, and see what it says. (I have a short program that prints out
the first 16 fibbonacci numbers which requires a coprocessor that I can send
you if you can't find anything else.)
