It's definite that the 10.0 stock "-smp" kernel omits PAE and hence

have thought it capable of handling that, but I've never tried and
don't have any real information. Maybe it's one of those things where
you have to buy the deluxe, chrome-plated, bug-reduced "enterprise"
version, or something...
Certainly that's a safe course of action, but there's very little risk
to adding or switching to the -bigsmp kernel on your existing 10.0
installation.
Then again, 10.3 seems very nice, and there's no reason not to upgrade,
other than the usual fact: Putting a new system in order, so
everything's just the way you like it, is always a time-consuming task,
especially if you're as picky and particular as I am, have a large
complement of packages installed, run several servers and so on.

Randall,
I think you are spot on in your response.
Stranger things have happened.
It is OS related. The BIOS page shows all 4096M recognized and
available. Neither the 10.0 default kernel or XP will use any more
than 3072.

I haven't tried the big-smp kernel yet. I have a spare 250G
drive I'll throw in and load 10.3 on with the smp kernel and see how
that goes. Thanks!
