press the HALT Button or (Control-P)
>>>boot -fl s

i tried following from bootprom(or whatever its called on dec systems)

passwd -c
passwd -s
new Password: ********
Retype new Password: ********
boot

But that didnt change the password.

According to The DECsystem 5100 Operator's Guide, "boot -s" should get you to single user mode.

Think i tried that but im gonna boot it up and try again, but after what i remember it came up asking for password once again.

I am new to ultrix but not to unix.

And by the way i think i got a hardcopy of the book somewhere(i got aprox 500kg of manuals with it)


Result:
KN230 V1.2
08-00-2b-25-27-9a
0x5000000
S> boot -s
-Usage: boot
S>
