In my (recent) experience, DOSEMU runs approximately 13x slower on F8-x86_64 than it did with F7-i386, on exactly the same machine. Conversely, it also shows that you CAN still run this type of software on x86_64, at the cost of requiring your CPU to do more emulation to get you there. Perhaps MS is simply not interested in adding this capability to Windows. This is a very interesting read if you want to know more about this subject: http://thebs413.blogspot.com/2005/10/what-is-x86-64-long-mode-memory-model.html -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
