That is very interesting.  Will the kernel use the two 2GB partitions
effciently?  I won't do the install until later, so I can still do this.
Very interesting.

We are not using 7.3 with this server because Dean says that Counterpoint
(the POS app) is having trouble running in 7.3  Perhaps something changed in
the many modules that must be loaded to run Counterpoint between 7.2  and
7.3  We are looking at it.
