What this code does: 

    This code can be used to identify if a Cyrix CPU and or Cyrix FPU 
    is present and what stepping it is.      

What files are included/what they do:

   build           -         The build file     
   isv86.asm       -         Test to determine if the current system
                             is in V86 or real mode
   id_fpu.asm      -         Determine if FPU is a Cyrix FPU
   lowlev.asm      -         2 routines to read/write Cyrix
                             configuration internal registers.
   cpuid.asm       -         Support to determine if CPUID is
                             available and a routine to use CPUID
   isfpu.asm       -         Check if an FPU is present
   id.asm          -         Test for Cyrix CPU 
   bad_op.asm      -         Invalid opcode handler 
   aorb.c          -         Test for A or B step DLC/SLC
   cpu_type.c      -         Figure out what Cyrix CPU is present
   is486.asm       -         Check for 80486 level present
   displycx.c      -         CPU name screen print
   cyrix.rsp       -         response file for many file names
   cx_funcs.h      -         prototypes
   cpu_type.h      -         CPU DIR0 Values
   cxid.c          -         Main routine
   cxid.exe        -         Compilation/Link of above
