Hi John,

great to hear that! I just checked out mptutil on 7.0 and it works
fine with a bunch of Dell PERC 5iR :)

Do you mind if i grab the sources and create a port of it? I guess many
people are eagerly waiting to monitor their mpt arrays as stated on
several lists. This would also give mptutil a much greater base of
testers.

Best regards
Patrick
