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... > Also I am seeing EMM386.EXE protection errors from time to time... Any > assistance on EMM386.EXE set up would be appreciated. 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?
