Returns: CF    NC (clear) if successful; else AX = DPMI Error Code
AX    coprocessor status bits (see below)
                                                                  
Info: This obtains information about a numeric coprocessor -- whether
one exists, its type, etc.

AX on return, contains the following bit codes:
1 1
 5 4  -  7 6 5 4 3 2 1 0 
     ...   type          
      -                   bit  mask
                   0: 0001H 1=enabled for this client
                1: 0002H 1=client is emulating coproc
                2: 0004H 1=numeric coproc is present
                3: 0008H 1=host is emulating coproc
              4-7: 00f0H coprocessor type: 0=none
2=80287; 3=80387; 4=80486
5=Pentium coproc

Notes: You can use INT 31H 0400H to determine the CPU type, but you
should not make any assumptions about the presence or features of
a coprocessor based on the return from that call.
