Ultra 10 - no output to monitor

Ultra 10 - no output to monitor

Post by Flatulous » Mon, 03 Dec 2007 12:00:13


I have the following system, which I purchased on eBay as parts and
assembled:
Sun Ultra 10 Elite 3D with 512MB
SymBios 22801 SCSI card
Seagate ST118273W 18.2GB 68-pin SCSI drive
68-pin ribbon cable
Sun Type 5 keyboard and mouse
Sun 17-inch CRT

Well, actually, the last two items are from an old MicroSPARC system
that I have. I think I assembled everything correctly... SCSI card in
PCI slot, jumpers set, hard drive power and ribbon cable attached,
keyboard and monitor connected. I have Solaris 8 that I want to
install, if that will work on this configuration.

When I turn the system on, it sounds normal, lights flash on the
keyboard, but the monitor remains black. Stop-A does nothing. I even
attached a PC monitor to the D-sub port, but no joy there either. It
seemed like there was some signalling coming from the CPU to the PC
monitor, but after a couple of flickers, it remained black. As I
mentioned, I have a MicorSPARC that I did system maintenance on for a
few years, so I'm pretty familiar with Sun/Solaris. I'm really
stumped about this. Is the CPU I bought on eBay D.O.A.? Any help
would be appreciated.

Did you try connecting a terminal to the console port (serial port
A)? It could have all output forced to the serial console in OBP.
Setting the OBP to defaults would fix that.

Yes, I thought that's what it might be, having read some of the other
threads. I'll give that a try. Thanks.

One other possibility could be that the resolution is set to one
which the monitor will not support. I've had the same problem with A
couple of machines which I have just retired (and thus the
"output-device=" setting was for a resolution which kept our LCD screens
happy, but not the 17" Sun monitor. I got just the same results which
you did -- with the final status being that both the green and amber
LEDs were on on the monitor.

So -- give it the magic keypress which will force the OBP
settings to the defaults (in particular, "Output-Device=screen" without
a resolution on it. The magic keypress is "STOP-N", in case you didn't
know.

If it *does* turn out to be the system board -- you can probably
pick up an Ultra-5 for less money -- and they are the same, just in a
different package -- so you can swap the board to your current box to
take advantage of all the extra room in the Ultra-10 box.

Good Luck,
DoN.

Thanks for the helpful suggestions. I tried Stop-N early on when I
found there was a problem and have tried it several times since. It
has no effect that I can discern. I was thinking of trying a tty
connection to the serial port using a null modem cable from my PC and
HyperTerminal. Do I need to disconnect the keyboard for that? I read
somewhere that you won't get a tty connection if the keyboard is
plugged in. Is it possible the prom battery is dead? It sounds like
I need to replace the prom if that's the case.

Regarding the monitor resolution, the light remains green and there's
no indication of a signal of any kind to the Sun monitor. The hard
drive is currently blank, no system installed, so no monitor
resolution settings coming from Solaris. What's the default monitor
resolution coming from the BIOS? I think the monitor is designed for
1152x900.

I feel like I'm in a little over my head here. I've done a fair
amount of system admin on a working sun box, but have not gotten into
the hardware like this before. I'm much more comfortable in the PC
hardware arena.

Hi
Use something like teraterm as you can send a break command when you
see the system info appear.

http://hp.vector.co.jp/authors/VA002416/teraterm.html

It will default to ttya( or b) if a console cable is connected. Look at
the Ultra10 Service manual for the pinouts. I have some of the sun DB-9
-> RJ-45 connectors so it's easier :-)

On my sunblades you can double click on the power button after the
beep to set defaults.

Okay, a little progress. I installed teraterm on my PC, connected a
null modem cable from the PC to ttya, and got an ok prompt after
starting the Sun. Specifically, I got this:

Data Access Error
ok

From the teraterm Control menu, I sent a break, Alt-B. I then hooked
the Sun back up to the monitor and keyboard, but still get nothing on
power up. Well, I get a single loud beep and the keyboard lights
flash on a couple of times, but nothing on either monitor. Any other
suggestions would be greatly appreciated.

Connect null modem cable (9600,n,8) to ttya on your U10, then turn it on
with Stop-D pressed. U10 will go through Power-On Self Test sequence,
dumping its results to ttya. Hopefully you'll see what's wrong.
If you've got Type-5 or Type-6 Sun keyboard, its LEDs indicate certain
types of errors.

What is input-device and output-device set to?

At the ok> prompt you type printenv to find out what all the current
settings are.
The input-device should be set to 'keyboard' and the output-device should be
whatever video connector you're using.
Usually 'monitor' is the correct setting for most purposes.

To run a full diagnostic at the ok> prompt do:

ok> setenv auto-boot? false
ok> setenv diag-level max
ok> setenv diag-switch? true
ok> power-off

Then power the machine back on via the front power button.

Be sure to put diag-switch? back to false when you're done to avoid a full
diag every time you do a power cycle.

Hmm, it certainly did. Near the end it said:
Status of this POST run: PASS

Unless I missed something, here's the only anomoly, which appeared
right at the end before the ok prompt:
Probing /pci@1f,0/pci@1 at Device 1 Data Access Error

I think this is the same Data Access Error I'm getting at boot up
without the diagnostics.

The only other anomoly is that boot cdrom always terminates
prematurely with: Memory Address not Aligned

I now have a theory about what is going on, at least as far as the
keyboard and monitor is concerned. The U10 service manual lists
supported I/O devices, which includes 17-inch color monitor, but
indicates 1280x1024 resolution. I believe the one I'm using,
purchased in the mid 1990s, only goes up to 1152x900. It could be
that the system is not recognizing this as a valid Sun monitor (for
the U10) and is forcing a ttya connection, also disabling the keyboard
in the process.

I wonder what would happen if I removed the Elite 3D card and had just
a PC monitor connected to the D-sub port. Would it default to the
onboard VGA? I really don't need the Elite 3D for my application. I
was hoping to use a PC monitor anyway.

Thanks very much foir all the help I've gotten here. I'd be dead in
the water without it.

O.K. It does have to be held while the system is powered on,
and kept held through a certain point in the power-on sequence.


Yes -- you have to unplug the keyboard to divert I/O to/from the
terminal. And do you have a breakout box to make sure that each system
is talking on the right pin and listening on the right pin? You will
want to connect to the 25-pin serial port (labeled "A" or "TTY A", not
the 15-pin one.


Hmm ... I think that you would simply get a problem in the
HostID and the ethernet Mac address (both of which are normally
displayed at boot time -- either on the screen or on the ASCII
terminal.)


Hmm ... green is a signal that there are horizontal and vertical
sync being received by the monitor -- unless it is too old a monitor to
have the power-saving capability, in which case it won't even *have* an
amber LED beside the green one.


That is the default for the system -- pretty much the default
for most Suns (except really old ones some of which had 1600x1200 B&W
only -- and took near forever to warm up enough to see anything on the
screen. These would have been 19" monitors, and for Sun-3 machines at
the latest.

Note that some monitors pull to ground certain pins to signal a
resolution other than the default -- and if the system's framebuffer
can't generate that resolution, you won't get anything from it.

Does your Ultra-10 have the framebuffer card installed which
gives a 13W3 connection, or are you using the VGA style HD-15 connector
which is part of the system board? If all else fails, pull that card,
and connect a PC monitor to the VGA connector and see what you get. It
won't support as wide a range of resolutions, nor as much color depth,
but it should work for diagnostics purposes at least. The two Ultra-10s
which I am using as web servers both have the fancy (Creator-3D) cards
pulled and use the VGA connector,, because that is all that I need for
the web servers. If I want to view the images in proper color, I
connect via the web to the systems. :-)


While I've spent a lot of time with various Suns in various
stages of working or not -- all the way back to the 2/120. :-)

Good Luck,
DoN.

You don't have it connected to a net hub I presume? It can be
either 10BaseT or 100BaseT -- the system auto switches. But -- this
failure should not prevent the rest of the boot sequence.


Reasonable for it to complain -- because you can't test its read
or write capabilities without a floppy in the drive. But this should
not stop things either.

Now -- you should get your "data access error" when it tries to
read the unformatted hard disk -- but it should go on past that, too,
and eventually come back to the "ok" prompt.

I did not notice it reaching the stage of testing the RAM.

How much RAM do you have in it -- and where? The FEH, for the
375-0066, 375-0079 and 375-0115 system boards states "The minimum memory
requirement is two DIMMs in any bank. And the banks are two adjacent
DIMM sockets -- bank 0 being the pair closest to the edge of the board,
and bank 1 being the pair closest to the UPA slot (the slot for the
Creator-3D framebuffer, which is *not* a PCI bus card.)

Hmm ... also -- are there any PCI cards in the system? I would
pull them, and the Creator-3D framebuffer, and perhaps half of the DIMMs
if you have all four DIMMs. If it does not pass the RAM test then, try
exchanging the two which you still have in with the two which you
pulled. I have seen failed DIMMs, or failed cards lock up the bus on
various systems.

Good Luck,
DoN.
