Thanks, that works! I also turned off write lock, which makes it happier.

Wow, that boot sure takes forever. What the heck is it *doing* for all of that time? :)

And at the moment, it's still booting, as I sip my morning coffee. Just started printing like heck and beeping... Ah, it's printing all of the licenses that have terminated. Maybe I should have lied about the date? Looks like the hostname is PIKE. Sure glad my iPhone boots more quietly.

VMS use not authorized on this node. I sure hope it won't enforce that before I can try a backup!

Finally! A login prompt! And no clue about the passwords. Uh, how can I shut this beast down without a  valid login? !?

Great. :)
