VP/ix seems to do the same thing.  The equipment byte in the "virtual CMOS"
says there's a FPP whether there is or not.  (VP/ix 1.1, ISC 1.0.6)

I've had an FPP initialization problem crop up recently, too.  When upgrading
from 1.0.5 to 1.0.6 on a Micronics motherboard with a 287, Unix no longer 
recognizes the coprocessor.  I wrote a little program that uses the sysi86()
call to check floating point hardware.  Under 1.0.5, it said there was a 287,
under 1.0.6, it says no FP hardware.  And floating programs are very slow 
under 1.0.6; it's obviously not using the coprocessor.  Has anyone else had
this problem?
