[comp.sys.att] 3B2 Floppy Key Problem

paulm@psu-cs.UUCP (Paul Mauvais) (10/15/88)

I have a 3B2/300 with 2MB of RAM and an internal 30MB HD

Someone in charge of the 3B2 before me changed the hardware
password to something different from the default, and now
no one knows what.  So, I follow the nifty manual directions
and use my floppy key to reset the NVRAM.  

Nothing.  It resets the date/time just fine, but does nothing
to the hardware/diag password at all.

Any suggestions on what I can do??

No problem.  Just remove the cover, locate the battery and disconnect
it for a minute.  The password will go back to it's default.

  You have a better idea? Now's the time..

The way we reset it is to unplug the nicad battery pack.  It is in the right
front corner of the machine.  Just pop the lid and unplug it....
Beware, ALL VRAM is scrozzed, so you will have to reset date, time and nodename.
The Firmware password will be reset to "mcp".

In order to find the firmware password (I don't know of a hardware
password) if one can log in as root, just use the crash(1M) program.
The crash command "nvram fwnvr" will display various firmware
parameters, among them the firmware password.  This works for my 600
running 3.1.1.  I haven't used an earlier 3B2 release in a long time,
so I don't remember if that particular crash command existed previously.
I would hope so.


Enjoy,
Gregg

  Neat!  I didn't know that existed.  I read this, turned around to my 3B2
and typed the crash command, got the ">" prompt, typed 'nvram fwnvr' and
it worked.  This is on a 310 running release 2.0.4.

The easiest thing to do is to unplug the battery source to the NVRAM.  This
returns all the internally stored items to their initial state including
the firmware password.  In case you don't know it, it's default value is mcp.
Another thing to note when entering the firmware password is that the terminal
must be set to 9600 baud, and space for parity.

I had a similar experience once, I even went as far as to
remove the NV-RAM battery.  No luck. . . .

I was about to call out a very expensive serice call when it suddenly
hit me.  Some idiot (in this case me) had set the console to even
parity.

It turns out that, while the UNIX System /dev/console driver was
only seven-bit significant, the firmware is eight-bit significant.
When I set the terminal back to 9600-8-1-N the password worked fine.
(yes verginia, it will be "mcp"  [Thank you Disney Productions] ;-)

Boy was that a stumpper for about 5 hours ;-)

On a side note:  Using the floppy key is identical in function to
removing the batery (aledgedly) but you must *make* the key
durring the inital installation (or any time there-after) yourself.
The disk labeled "FLOPPY KEY" that comes with the rest of the stuff
is just a blank, formatted diskette.

This is the case because the key must have the serial number of
your system board written on it (with other information too)
for it to work in your system.  This means that you can't use
one key in another machine.  (those of you who have floppy
keys already know this, but a lot of people I used to work
with didn't.  Not fun, nor funny.  So I thought I'd take the
extra bandwidth to mention it.)
