When you run mopd use 'mopd -d' initally (or "mopd -d -d" as more "-d" 
options get you into higher diagnostic levels). WHen your vax tries to boot 
it should show up on the tty where mopd is running.

Most common problem is that mopd wants things in all UPPPERCASE like 
MOPBOOT.SYS even though you type the name to the vax in lower case.
