First off Duncan, you have to think about this. 2 four GIG sets of memory?
That would mean you would have some combination of 8 Gigs of ram/hard drive
space. Anyone with that much power wouldn't be using os/2.

Each and every DOS program get's it's own virtual machine. Windows programs
can either run under one virtual machine, or under several virtual
machines, at your option. If I understand the OS/2 programs right (and I
probably don't) they each get their own virtual machines also, but they are
different from the dos and windows programs.

James Blackwell
