[comp.sys.att] Help with AT&T 3B2/300

best@seas.gwu.edu (keith best) (02/14/90)

I need help from some Unix gurus out there....preferably those familiar with
AT&T's line of 3B2 computers.  The library where I work has a 3B2/300 computer 
that has not been used in about 4 years.  I recently tried to set it up for someproductive use but I do not have the passwords for ROOT or SYSADM.  Therefore, it is practically useless.  The previous system administrators are no longer available.
I have all the original software and documentation (I hope) and would not discard the idea of deleting everything and reloading the system from scratch.  I have followed the ROOT RECOVERY METHOD as outlined in the documents to the letter without success.
Previously when I tried to access the FIRMWARE mode, I got an NVRAM SANITY 
failure: I have since replaced the battery, but now I get a SYSTEM FAILURE: 
CONSULT YOUR SYSTEM ADMINISTRATION UTILITIES GUIDES.  This guide does not mention this error message.  The FLOPPY KEY disk gives the same error.
The system is running SYSTEM V Release 2.0 3B2 Version 2.0.  We are way past
support from AT&T who donated the computer system so we would appreciate any
help from knowledgeable users out there.
                                                   Thanks in advance

I am in exactly the same situation as Keith. I too, have an aging 3b2/300
that was being thrown out and I volunteered to take it over. We don't have
the floppy key disk for the system. When I turn it on, it gives me the
same NVRAM SANITY FAILURE mentioned by Keith. And yes, I replaced the battery
too. I still get the same message.

Any ideas from those who have tried to restore a 3b2/300 to life ? Your posting
may help save the life of a 3b2. Write soon; operators are standing by... :-)

The System failure message is nothing to be overly concerned about.  When that
message comes up, you should enter your firmware password, (the default, as
can be found in TFM is "mcp".  If the password doesn't work, check the parity
of your terminal.  Try using 8 bit no parity or 7 bit space parity on the 
console terminal.

Once you've entered firmware mode, you will probobly be more comfortable if
you rebuild the system from scratch.  There are two reasons for this.  1)
If you don't know the configuration and setup of the system, it will start you
out with a clean slate.  2) You will probably learn more about the system by
setting it up yourself.

If you have further questions, feel free to e-mail me.

What you need to do is type in: mcp and return. The machine will not echo
the characters back to you. If you get:
SYSTEM FAILURE: CONSULT YOUR SYSTEM ADMINISTRATION UTILITIES GUIDE
again then check to make sure that you have your terminal set up to
9600 baud no parity. You should then see:
Enter name of program to execute [  ]:
you type in unix and enter.
Next you will see:
Option Number    Slot     Name
---------------------------------------
       0          0     FD5       
       1          0     HD30          

Enter Load Device Option Number [1 (HD30)]:

Type in 0 to boot from the first floppy of the core set. After a minute or
so the machine will come up and ask you if you want to do a complete restore, partial restore, upgrade or dual disk upgrade. You should then type in:
magic mode and return. You will then be get a shell so you can mount the hard 
disk and remove the password from root. To mount the hard disk
type in /etc/mount /dev/dsk/c1d0s0 /mnt. Then cd /mnt/etc and
use ../bin/ed to edit the passwd file. After you have done this
you can cd / and /etc/umount /dev/dsk/c1d0s0. Next step is to type in /etc/uadmin 2 1
to get the machine to reboot.

If you have the boot disks used to install UNIX, you may be able to start
the disk, excape (del, or ctl \ ) the install process and have a unix running.
then mount the root partition, and zap the password in /etc/passwd.

CAVIATE: This is how to do it on ATT UNIX for 386 machines.  It may also
work for you.
