Thanks!!!  When I get ready, and if I get some stuff working,
I'll also let you know.  I have the mptable program for FreeBSD
(I had to modify the FreeBSD config so that the Dell would work,
 it has more INTRs than FreeBSD normally configures), it provides
the (sometimes interesting) mapping info also!!!
