Since you don't see the netbsd boot program showing up I would guess your
mop stuff is not working.
The notes indicate that the mop file name on the mop server must be upper
case.  I'd check your mop configuration on the mop server.  This is what I
have for my mop configuration:
====
csserver2.wheaton.edu> pwd
/tftpboot/mop
csserver2.wheaton.edu> ls -l
total 134
lrwxr-xr-x  1 root  wheel      8 Sep 12 08:36 MOPBOOT.SYS@ -> boot.mop
-rw-r--r--  1 root  wheel  68096 Sep 12 08:36 boot.mop
====

(The mopd is running on NetBSD system).

Annother thing you might try is init before you attempt to boot.  There
were several times things did not work on my MV3100 when attempting to
boot and init seemed to resolve the problem.
