Ah, yes, I believe this is a limitation of DR-DOS EMM386.EXE. But at least
it works... I tried installing Qualitas Memory Manager on top of DR-DOS
and it crashes with a stack error when it sees more than 64 MB of memory.  
I believe you can use more memory than that with Quarterdeck Memory
Manager if you can find a copy.

But, what is the problem with only 64 MB of memory? What DOS application 
do you want to use that is unhappy with only 64 MB memory? I just learnt 
to live with this limitation...

Hmm, me too. My old DOS graphics app doesn't like DR-DOS NWCACHE.EXE
combined with DR-DOS EMM386.EXE (It either refuses to run, or sometimes I
can get it to run, but then it crashes drawing graphics). The fix was to
install Norton Utilities and use NCACHE2.EXE instead. Otherwise, other
programs seem to work fine (WordPerfect, Arachne etc). What app are you
having problems with?
