V5.5 runs well on MV-II with full load of ram. If your less than full
ram consider 4.7 though 5.2 also runs ok that way.

Another option is after netbooting BACKUP you can do an image copy the disk to
the MVII, either net is slow but still faster than TK50!!! I've done this.
The 3100 I use has a small (100mb RZ2x) and it's a bootable system though
cramped and I can use backup and image copy it to RD54 sized drives via
'net. That way I clone the OS to machines then tweek it (system name and
all that stuff). Saves a bunch of time and messing with TK50s that tend to
do annoying things.
IF you have a SCSI adaptor (even if you can't leave it in the system) you
can create a disk on a 3100 or whatever and then transport the adaptor and
media to the MVII and copy to the MSCP drive.
