Umm. A 4GB limit would be just fine in my case. In fact I will probably=20=

not need much more than 3GB, it is just that I've tried running my=20
machines in 96MB each and that was too painful so I need to break the=20
2GB barrier.

I'm confused. Although I've never tried it myself I've seen numerous=20
messages on various mailing lists about NetBSD/i386 on machines with=20
more than 2GB memory. I was under the impression that the limitation=20
primarily was that the i386 arch cannot address more than 2GB per=20
process. What am I missing?
