You introduction really made me wanting to try out DOSEMU. It's unfortunate
that I allocated all my hard disk space (120GB) of my computer to Windows,
so the option would be limited to a Virtual Machine. Thus I'll try your
idea, with DeLi + DOSEMU inside VMware or Virtual Box. Thank you for your
Robbie (Decheng) Fan
