Protected Memory mode.
The syntax changed from 4.11...
Hmmm. looking around I don't see an reference to it in my stuff.
Googling....[link|http://developer.novell.com/research/sections/netmanage/netnovice/2001/june/n010601.htm|Best I can find]
I expect 4.11 doesn't have true protected memory space options, but at least you can try it.
I know for sure the Early Betas of NW5 had it... I suspect the last of the 4.11 intranetware service packs may have too.
