It's been a long time since anyone has mentioned so many obsolete software
products in a single message. LOL
I can't help you out other than point out that the two memory standards
(DPMI and VCPI) pre-date Windows and *its* memory management and may never
be compatible. If they are compatible, great and good. It's an accident, but
a great accident. <g>
Wow ... what a blast from the past.
