386, yes. 286, no.

CWSDPMI.

On your favourite simtel.net mirror in the directory v2.

Yes, with a DPMI server supporting virtual memory (CWSDPMI does).

No, WINDOZE is the DPMI server. Any writing on disk will be done by
WINDOZE. Set as high as possible values in the DPMI memory DOZE box
properties (65535). Alternatively, boot into plain DOZE and use
CWSDPMI here as well (which will give you more memory than WINDOZE if
you have the disk space).


Right,
