I just netbooted a vax station 4000/90 from the boot loader distributed
with NetBSD 6.1.3.

I used a NetBSD/i386 running 6.1 as server, started

  mopd -s /usr/tftpboot/mop sk0

with this content:

lrwxr-xr-x  1 root  wheel     11 Apr  1  2009 0000f85169e1.SYS@ -> MOPBOOT.SYS
-rw-r--r--  1 root  wheel  60176 Feb  3 14:04 MOPBOOT.SYS
-r--r--r--  1 root  wheel  63600 Apr  1  2009 MOPBOOT.SYS_working
[/usr/tftpboot/mop] root@night-porter # file MOPBOOT.SYS
MOPBOOT.SYS: ELF 32-bit LSB executable, Digital VAX, version 1 (SYSV), 
statically linked, stripped

and MOPBOOT.SYS is just a copy of the netboot/boot program from 6.1.3.

This is the mopd from NetBSD base.
