Indeed you should run cpu060. That'll tell you if it has FPU or not, for sure.

ShowConfig checks AFB_68881 flag for FPU... And this flag is only set when 6888x FPU emulation routines have been loaded (the flag is set by 68060.library).

Code: [Select]
/*
 * The AFB_FPU40 bit is set when a working 68040 FPU
 * is in the system.  If this bit is set and both the
 * AFB_68881 and AFB_68882 bits are not set, then the 68040
 * math emulation code has not been loaded and only 68040
 * FPU instructions are available.  This bit is valid *ONLY*
 * if the AFB_68040 bit is set.
 */

The same applies to 68060.

So non-functional 680x0.library will result in ShowConfig not reporting the FPU, even if it does exist.

@ Piru, if you are referring to the "CPU060" command that comes with the phase5 060 cards then I did try that and it didn't work.  From a cli I ran it but it just hung the shell, no output.  (I can try it with different 060 libs though - I tried it with the supplied ralph babel/jeff boyer libs).

I did try Thomas Richter's 060 libraries on the computer and  "ShowConfig" did report that an FPU was present.  
I also loaded Thomas's MuRedox program and now your "WhichAmiga" utilitiy runs and says there is an FPU, but I am still getting weird crashes.

Then I went back to the ralph babel/jeff boyer libraries and ShowConfig STILL reported an fpu present...so there is not consistancy there...?? I don't get it. :(
