MC68881VERSION(8)           System Manager's Manual          MC68881VERSION(8)



NAME
       mc68881version  -  print  the MC68881 mask number and approximate clock
       rate

SYNOPSIS
       /usr/etc/mc68881version

AVAILABILITY
       Sun-2, Sun-3, and Sun-4 systems only.

DESCRIPTION
       mc68881version determines whether an MC68881 or MC68882  floating-point
       coprocessor  is available, and if so, determines its apparent mask num-
       ber and approximate clock rate and prints them on the standard  output.
       The  reported clock rate is derived by timing floating-point operations
       with getrusage(2) and is thus somewhat variable; best  results  may  be
       obtained  in single-user mode.  The same applies to the differentiation
       between MC68881 and MC68882 ; these can be distinguished in  user  mode
       only by timing tests.

SEE ALSO
       getrusage(2)
