Sun Blade 100 issue

    I'm currently trying to get a Blade 100 working. It will not output to the monitor. It currently has no OS. I can get into OBP via serial, but even though it outputs text, it will not accept keyboard input via serial. Does anybody know what is going on, and how to reset it to work via USB keyboard and VGA monitor?

    Hmm ... looking at the last edition of the Sun FEH (Field
    Engineer's Handbook_, I see in addition to the USB connectors, and only
    one serial port a pair of connectors (four pins in a straight line) just
    around the corner from the USB connectors, labeled:

    J33 PS2 Mouse Connector
    J34 PS2 Keyboard connector

    which suggests that those may be the default keyboard and mouse
    connectors. Inside the box, are there wires going to those two four-pin
    connectors from jacks on the back of the chassis? It has been a *long*
    time since I last did anything with a SB-100, but I don't remember any
    problems at the time. Mine is deep into a storage shed, and it is dark
    and cold out there right now, so I'm not going to try to dig my way to
    it. :) (Hmm ... also, based on the PDF files I have stored here, it was
    a SB-150, not a SB-100.)

    Note that since it says "PS2", it would not be the normal Sun
    keyboard and mouse, which would use a single connector for both, and
    would be an 8-pin connector instead of the 6-pin used for PS2. So -- if
    you have those connectors on yours, try a normal PC keyboard for

    But -- the service manual for the SB-150 says four USB
    connectors, of which two are for the keyboard and mouse .

    Various monitors listed, witht he minimum being a 1152x900
    resolution, and others up to 1920x1200. The connector is listed as a
    VGA connector.

    Is it possible that an alternative framebuffer (video card) is
    present in the machine, and it is taking over the function? It could
    have another VGA connector, or the 13W3 connector used for earlier Sun
    monitors. (13W3, in case you have not seen the earlier ones, is the
    same shell as the DB-25, but has three coax pins, and ten normal pins,
    with the coax pins carrying the three video color signals.

    If there is a second framebuffer card, pull it and see what
    difference that makes. It may fall back to default.

    Now -- one way to reset to defaults is via a Non-USB keyboard,
    where you turn on power and hold both the STOP key (upper left of left
    keypad) and 'N' key down until the keyboard LEDs flash. (This assumes a
    Sun keyboard and the DIN-8 connector, which I see no provisions for on
    this system. With USB keyboads it does not look at them soon enough to
    do any good here -- but there is an equivalent way listed (for the
    SB-150, and hopefully it will work on the SB-100 as well).

    1) After turnin gon the power to your system, wait until
    the front panel power indicator LED begins to blink and
    you hear an audible beep.

    2) Quickly press the front panel power switch twice (similar
    to the way you would double-click a mouse.

    A screen similat to the following is displayed to indicate that
    you have sucessfully reset the NVRAM contents to the default
    values. If a screen similar to the following is not displayed,
    repeat steps 1 and 2.

    Sun Blade 150 (UltraSPARC-IIe 650MHz), Keyboard Present
    Copyright 1998-2002 Sun Microsystems, Inc. All rights reserved.
    OpenBoot 4.6 build_10, 1024 MB memory installed, Serial
    Ethernet address 0:3:ba:e:57:73, Host ID: 830e5773.
    Safe NVRAM mode, the following nvram configuration variables
    been overridden:
    'diag-switch?' is true
    'use-nvramrc?' is false
    'input-device', 'output-device' are defaulted
    'ttya-mode', 'ttyb-mode' are defaulted

    These changes are temporary and the original values will be
    restored after the next hardware or software reset.



    Then, you can type "set-defaults" to reset *all* to default

    Hopefully, enough of this will apply to the SB-100 as well as
    the SB-150.

    The part number for the SB-150 service manual is 816-4379-10,
    and maybe you can find the corresponding one for the SB-100.

    Good Luck,

    No other ports for keyboard, only USB. Yes, I know about the Sun keyboard reset routine as I own an Ultra 5.

    No other graphics apart from on board.

    Power button is how I brought up the serial console, but it is ignoring keyboard input via serial.

  4. By default, it should accept input if no keyboard is attached.

    Are you sure the serial port is properly connected? I seem to remember
    that not getting it input might be caused by wrong wiring.

    What does it say during starting about input & output>?

    Have you tried a monitor & USB keyboard?

    If Casper says so, it is true. (Glad to see you still here.
    Looks as though you are still with what is left of Sun, too, if I
    interpret your spam-proofed email correctly.)
    I remember that some of the earlier boxen were paying attention
    to the CTS pin or the CD pin -- and that has to be pulled true to get
    output from the system -- but I think that ended before the SS-10 or
    even the SS-5.

    But -- maybe the system you are using as a terminal is expecting
    the CTS pin to be true. To be sure, force CTS and DTR both true on both
    sides of the connection.
    I suspect that the OBPROM EEPROM settings are directing the
    input and output to the USB and monitor -- so you need to issue a
    reset-all, but you can't until you can talk to it. Sort of a Catch-22.

    Here are some (examples from a "Sun Fire V120", not a SB-100)
    which might be causing you problems, depending on how they are set:


    Note the "output_device" settings. If it just says "screen" you
    should be fine. As shown, it is expecting a particular resolution of
    monitor, and if your monitor won't do that, you won't get anything
    useful on the screen. It could also say "ttya" or "ttyb" on each. I
    guess that it could even be set up to accept input from one serial port
    and send output to the other, though I can't imagine why anyone would
    want to do that. And if they did that, they could have a different baud
    rate on input vs output.
    Even a Windows USB keyboard could do it -- though it makes
    things more difficult. And the monitor needs to be happy with the
    1152x900 resolution -- but some other resolution may be set in the
    EEPROM settings.

    Good Luck,

  6. I am not always right and the last time I used a Ultra-5 or 10 is
    a long, long time ago. Also, if the defaults have been overwrritten
    it might want to read from the keyboard. And, yes I'm at Oracle and
    still in Solaris engineering.

    IIRC, if you get output on the serial port, then it certainly will
    not send output to the framwbuffer.

    It gets worse, there is now an SB150 which also won't output to the monitor!

    What can I type blind at the system keyboard to sort this out?
    Feel free to email me:

  8. You could try Stop-N (if you have a Sun keyboard); it resets the
    keyboard to the default (as long as it doesn't have a password set)

    I have accessed the 150 via the serial port, and this one takes the keyboard input via serial. Oddly, still can't get video on either an old CRT or a modern LCD. Are these systems a bit picky about what monitors they will work with?

    I will have to try Stop-N on the 100. Will that select the console keyboard as default, and input via serial when on serial with no keyboard? No password is set.
