HP3000/922 attempts at booting...a little further now!

Wow! That helped a LOT! I can now get booted, the OS loads and I
get to a login prompt. Any pointers on
how to proceed at this point? (to get logged on, find out more about
how the system is configured etc)?
(I have no info on usernames/passwords on this system).

>>> The external drives have ID's of 2 and 4.
