This info, in fact, is probably wrong. Looking through my paper files,
from OpenCD, there is available a 48KB file "md5sum.exe"
which goes into \winnt\system32. I apparently had already d/l this
file and put it there manually. Look at //theopencd.sunsite.dk/md5.php

Tnx Doug for reply, I thought it would be radically different.
