First: i cannot compile correctly mopd under linux. Why? I don't
understand. But i can find on the net linux binaries (if you want, i can
send to you, or put to public ftp)

!!!Do this:
************ On linux station type: "ifconfig eth0 allmulti" ************
Without this, the VAX cannot boot from linux host.

And the GENERIC 1.4.2 (and i think 1.4.1 too) has a problem:
probe boot via bootp and bootparamd too. I cannot determine wich boot,
wich protocol.
Ex.:
1st boot probe:	VAX probe via bootp
2nd boot probe:	VAX probe via bootparamd
3rd boot probe:	VAX probe via bootp
4th boot probe:	VAX probe via bootp
5th boot probe:	VAX probe via bootparamd
(I think: this is random-change)
Of course, the first boot stage: get mopboot image from host is
succesfull.
In second boot stage probe bootp or bootparamd.

If you have VMS and network on your VAX, you can boot (or install) NetBSD
more easy than linux-mopd-bootp*-.... way.

One way if you have VMS (not fine, but if not working anything else):
Convert the boot image (not the boot.mop!) to the ASCII format.
Example: bin2hex,.....
Send this ascii file to the VAX over console.
Convert back to binary.
At now, you can write to any hdd, about:

$mount dxx: /foreign
If not good anything, add the /blocksize=512 qualifier to the mount
command line.

$copy netbsd.img dxx: /contiguous

at now: halt the system, and the chevron type: "boot dxx:"
