Please try again, and please try it with different values, both above
and below 512K.  Also, run CWSPARAM and set CWSDPMI's run option flags
to 1.  See below for the reasons.

This means that you have only 532K of conventional memory and NO UMBs
or extended memory!  In other words, CWSDPMI *must* work out of
conventional memory, and it must *not* use UMBs.  Run-time option 1
forces it not to use UMBs, setting the minimum application memory to
an appropriate value should force it to use conventional memory
instead of the (unavailable) XMS.

But I don't understand what happened to the 3MB of your extended
memory?  Do you have any memory managers installed?  Please post your
AUTOEXEC.BAT and CONFIG.SYS.

This is probably a very good idea.

This is a low amount of disk space.  Did you try to disable the
swapping by pointing the swap file to a non-existent drive (run
CWSPARAM to do that)?  If not, please do.
