Why do you say OS/2 is not an option. You are flailing away desparately with junk software that is bound to cause you such difficulties, and unless you have extremely odd requirements, which are certainly not clear from your post, OS/2 would entirely solve your problems at a cost of $49. Using OS/2 you should find that you have plenty of conventional memory for DOS programs, and that further more you can run several of them at a time (I do so all the time on my TP750). In addition, if you just run DOS, I would say that you wasted money getting a 16M card, clearly there is no way you can make decent use of that extra memory.
