[comp.sys.att] 3B2 Device table wierdness

bill@ssbn.WLK.COM (Bill Kennedy) (02/04/90)

This one has me stumped and I don't even know how or exactly
when it happened.  I have a 3B2/310, 2Mb, MAU, XM chassis
with CTC and a second 72Mb drive in it.  I have had to replace
the power supply and the internal hard disk, this happened
between the power supply and drive, I _think_.

The sign on and edt display used to show that I had the SBD,
two HD72's, PORTS, MAU, and CTC.  During the failure or
replacement of the power supply or drive 0 it started saying
that I have the SBD, HD10, NULL, PORTS, MAU, and CTC.  There
is nothing wrong with the second drive or the first one for
that matter, but the display is wrong.  I've RTFM'd and if
it's there it's not in a FM that I have.  Does anyone know
how I can change /dgn/dgn_edt or NVRAM to make it reflect
the correct configuration?

Please email (since this is so odd) and if others want to know
too, I'll post the answer.  Thanks!

Brian Kantor (brian@ucsd.EDU) got me started, and I got several replies,
so I figured I'd summarize and maybe keep some others out of a dead end
street that has my footprints in it.  Thanks to all!

:
:I assume that you have 2 72MB drives and not a 10MB within you 3B2.
:If this is true, then I know what you have done, I think :-),
:Firstly, You have used drives that were NOT used previously in a 3B2.
:Secondly, you have formated these drives with the Idtools package.
:If this is what you did, then you didn't enter the correct drive type
:when you entered all of the data to format the drive.
:I think you must of entered '0 or 1' instead of '8'.
:If you don't know what I am talking about please talk to the person who
:formated your 72MB drives. Otherwise If you need a walk-though then I will
:give you the steps you need to go though to correct the problem.
:
:I had the same problem when I added a second 72MB drive to my 310. It
:came out as NULL and then as a Floppy device until I fixed the drive type.
:The information about drive types, I found out, is within the 3B2
:maintainance manual that comes with the Idtools.
:
:Hope this helps.

Mike Pearce had a perfect bulls eye, what he describes is *exactly* what
I had done.  Brian got me prowling around, and Mike confirms what I thought
I figured out.

:Try shutting down the system to firmware mode (either use shutdown -i5 -g0 -y)
:or do a normal shutdown and hit the reset button as soon as the system passes
:diagnostics.
:
:You will be asked for a name of a program to edit, at which point type
:"filledt".  This will re-write the equipped devices table for the appropriate
:devices.

What Richard describes, and then Mark (below) brings up an interesting
"feature".  I found a command, edittbl that will take some text and make
it into a file suitable for filledt and even put it in /dgn for you.  I
will ASSume that this means that you could invent some names for subdevices
and build your own table to describe a Frammis IV disk drive, Fortesite IX
tape drive, etc.  Then you could filledt with that and have something other
than those devices named for you.

:The command you need to run. I believe, is 'filledt(8)'.  It usually runs
:automatically at power-up, but I do remember some problems in the past.
