Same testing as with any early 90's server. If the server boots and
squeals to holy hell you prob have a bad drive, but the system is pretty
robust and if you have multiple drives it might seal it off and boot

Run the SHOW DEV command if you don't know what to B/1 (boot with diaglog)
to. This way you can reset the password if you don't know it. My system's
boot drive is DIA0:, yours will likely be different. Keep trying them until
it works. My VAX 4000 also has a DIA1: and a DIA5: among others.
>>> B/1 DIA0:
This will eventually drop you to the SYSBOOT prompt.
SYSBOOT> SET/STARTUP OPA0:
SYSBOOT> SET WINDOW_SYSTEM 0
SYSBOOT> SET WRITESYSPARAMS 0
This will drop you to the $ prompt.
$ SET DEFAULT SYS$SYSTEM:
$ RUN SYS$SYSTEM:AUTHORIZE
This will drop you to the UAF prompt.
UAF> MODIFY SYSTEM /PASSWORD=whateveryouwant
This will bring you back to the $ prompt. Log out
The VAX upon return then asked me to reset my password to something 8-32
