What do these prom messages mean?????

I just picked up a Tatung Ultrasparc I 167mhz machine at a
local computer club sale.  It gives me the following message:

   Can't clear ESP interrupts:  Check SCSI Term. Power Fuse.

I would think it has a blown scsi bus power fuse somewhere?

Where?  I am not familar with this particular machine.

Is there an online manual or pdf appropriate for this machine
that I should download?

Thanks

I got that very message from my SS20 after a power failure 18 days
ago.  Turned out that after I powered down everything on the SCSI
bus and then powered it all back up, it was fine.  I think these
antique DEC RZ55's I have hanging off the SS20 (or maybe the SS20
itself) don't deal well with power glitches.

Sounds like it doesn't it?  They are easy to blow, especially if you
are hot {un,}plugging equipment.

Not sure with tatungs - if it was an original sun, look for a
cylindrical plastic device somewhere near the scsi bus.  The fuse does
not look like your standard 3AG with a metal cap at each end, oh no,
these ones have a couple of wire "legs" that both stick out the same
end - these plug into a little socket on the board.

Have a look on <http://sunsolve.sun.com/> and see if you can get some
documentation on the "real" sun model - Tatung may (just may) have
taken the Sun design and used that in manufacture.  The clone I have
looks pretty much the same as a real sun board, the only difference
are the peripherals (using 50pin narrow drives instead of SCA drives
used by Sun in the same model)

Re: What do these prom messages mean?????

I still get the:

  Can't clear ESP interrupts: Check SCSI Term. Power Fuse.

message whether or not I have repowered the machine up or
down or not.  Also, it occurs even if nothing is on the scsi bus,
or all drives and cdrom are on the scsi bus (bus terminated at
both ends, of course).  I did a set-defaults to clear the nvam,
just in case anything funky was going on there, and also tried
without terminators and with different terminators.  It is beginning
to smell like something might be amiss with the scsi bus chips,
and I may see if I can dredge up another U1 motherboard to try.

Other than that, dunno what is going on.  Anyone else see this
kind of message on U1 machines?

Thanks

Not familiar with the machine, but the following google:
http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=sun+scsi+fuse&btnG=Google+Search

Pulled up:
http://www.netsys.com/sunmgr/1998-10/msg00037.html

which looks to contain some handy advice.

In summary:
- Make sure termination is correct. Only devices at the ends of the bus 
  should be terminated.
- If the fuse was blown by too many terminators, then having fixed the 
  problem you could configure another device to provide terminator power. 
  Most HD can provide power for the terminator with an updated jumper.

Finally, if all is lost, SBUS scsi cards can be had dirt cheap on ebay.

Re: What do these prom messages mean?????

I finally managed to get it up enough to get it to do a POST,
which reported a blown MACIO U1101 on the motherboard.
I guess it is time to find another U1 motherboard, since I
don't have the tools to do chip level work on these critters.

Speed is not always the most important factor.

Sounds great! I'd like to try your Xs24 server if it's possible.

Re: 24bit display problem

(I was going to send this off-list, but this is the second person in a
short interval who's been interested, so I'll tell the whole list.)

> Sounds great!  I'd like to try your Xs24 server if it's possible.

It should be FTPable from ftp.rodents.montreal.qc.ca:/mouse/X/Xs24.
(The FTP server can gzip and bzip2 on demand; you're supposed to be
able to get Xs24.gz or Xs24.bz2, even though they're not shown in the
directory listing.)  If you have trouble, please let me know.

You likely will need to tweak the tcx driver in your kernel a little.
I had to patch mine, and, on looking over a moderm tcx.c, I find that
it has only some of the changes applied.  I'm not sure they're all
necessary, but at least a few are.  In any case, the patches I applied
are also up for FTP, from the same machine, in
/mouse/source-tree/patches/working/src/sys/arch/sparc/dev/tcx.c.  (The
tcx driver has since moved to sys/dev/sbus, which is where it really
belongs.)

It seems sparc/machdep.c rev 1.230 fixes this problem.

With 1.6U kernel, time for compiling my custom kernel says:
> 13907.897u 11339.194s 7:31:19.53 -65.-3%	0+0k 84+13413io 287pf+23w
(I don't know why it shows negative values BTW)
With 1.6W kernel:
> 13744.456u 1748.553s 4:32:30.59 94.7%	0+0k 68+13313io 315pf+23w

I think now old sun4c machines become usable again after UBC merge.
Thanks Paul!

What kind of storage tray is a sun 540-3234 or 540-3005

I picked up a nice rack mass storage array with a bunch of 9g
drives in it.  The rack is powered by a differential controller that
runs to three boxes of drives that are 68 pin scsi (non-differential).
I would like very much to run one of the drive trays externally on
my Ultra 1.  I can't seem to find any model ID info on the mass
storage cabinet or the individual drive trays, so I can dig up some
docs on the critters.  The only numbers I can find are:

  540-3005

and

  540-3234

each holding 7 drive boxes,  540-2942.  It appears they are wired
for 240v, and I need to find out if they can be switched to 110v.
The label on the back has a possible model number OSM-3000-02
with a part number 501-8745.

None of these numbers seems to key out on a search.

Any insight as to what they are, and where some docs might be,
is appreciated.

Thanks

Bob Keys
