Running RawIO

[Rishi Chopra]

I am newbie who just installed RawIO ('cd /usr/ports/benchmarks/rawio',
'make install') but am having trouble running the benchmark.

I run 'pkg_info -L rawio-1.2' to see that the program is installed in
/usr/local/bin/rawio.  To run the program, I used:

'/usr/local/bin/rawio -a /dev/da0'

but the only ouput is a list of command-line switches and their definitions.
Am I doing something wrong?  My system only has 1 hard drive, and I've tried
using /dev/rasr0 with the same result.
