Look here, and scroll down to the part about Virtual memory space.

Oh, gawd yes. tweaking qemm to get it to do what it had to do. And all the
fun with EMS, XMS, and EEMS. But it _was_ stupid, silly and not very
efficient. Just the only game in town at the time.

Yup. But you won't be able to run XP on it with all those processors. But
think of the power. The mind boggles. Not something I'll be able to buy, but
still something I could _conceive_ of buying.

I know what you mean. I salivated on my keyboard when I saw this. LOL

But you know that you could run it with Server 2003 SP1 x64, right?


Wayne

Oh, yes, I could run Server on it. If I could afford it, of course.

Just get the Trial version, and keep re-formatting and re-installing every
179 days. ROFLOL


Wayne

The issue isn't the copy of Server -- I'm sure I could score that. And I
can't even imagine the pain of rebuilding my server every 6 months. Yuckk.
OTOH, one of those boxes does NOT come cheap. And no one's offering me any
freebies. If I were buying the server box of my dreams right now, it would be
the HP DL-585. Now that is one sweet box.
