That's what I gathered from freebsd-smp@ in last few months.
I just thought I would try and see what happened. :)

I couldn't find one.  Maybe I can get a new version of the
BIOS?  Are there any known problems with this version?  I
see on the SMP page that another person has made this board
work with version 1.4.

A million smileys to Steve Passe! :) :) ...

Yes, this works.  When you get a minute or two can you explain to
me the downside of making this change, if any?  I don't want to seem
like I'm looking a gift horse (or should that be super hacker :) in
the mouth, but I would like to know nonetheless.  Will this make things
run slower?  If so, how much?

Anyway, add me to the list of happy campers.  I am running the
'make world' stress test as I type this and everything is chugging
right along.

Are there any more tests that you would like for me to try?

Thanks a zillion,

Steve

PS: I will be working on merging in the Lite2 stuff to my local
    smp-sys tree this week (along with a bunch of other things) if
    there's any interest.  I am about five directories away from
    having src/sbin userland code up to Lite2, and when I get done
    with this I'm off to smp-sys land. :)
