MC68881VERSION(8) System Manager's Manual MC68881VERSION(8)
mc68881version - print the MC68881 mask number and approximate clock
Sun-2, Sun-3, and Sun-4 systems only.
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.
