I have gotten bug reports that it reports zero memory if there is over 2GB present. I suggest running in raw mode (no HIMEM) or XMS mode (only HIMEM, no EMM). It would be intersting to know what http://clio.rice.edu/djgpp/meminfo.exe reports on your machine in this configuration. > I have downloaded cwsdpmi, but then I get a "no channel" error. You will need to be more specific (exact error message) since this message does not originate in cwsdpmi. People have successfully used cwsdpmi on machines with 4GB of memory (even though only 2GB of is is usable) - it's just a matter of getting the configuration right.
