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. :)
