Having issue(s) with Sunblade 1000 and x3668a (370-3753) card. HELP!

    I bought both of these off of eBay and it seems that the Sunblade will
    boot up off of the CDROM
    that I'm using (Sol 10 5/08). However, I see a pixelated display
    instead of something "readable"
    on my HP 19" flat panel (it's locking in at 1280x10224-75 MHz).

    I am not sure what to do at this point. I noticed that there are 3
    jumpers on the card itself. Do
    these need to be in a certain position? Do I need to somehow find a
    null modem 25-pin serial to
    9-pin cable to check the settings?

    I'm stumped. I didn't have this kind of problem when using the same
    monitor on my Sunblade 100.

    You mean 1280x1024x75? (You got an extra '2' in the second
    figure).

    Did you buy them together, or separately?

    Does the screen show garbled before you actually try to boot, or
    only once the Sol-10 DVD is booted? (If you can't see the screen, how
    do you boot from the DVD-ROM? You need to see to type "boot cdrom" at
    the "ok" prompt.

    Is it possible that the monitor is locked to a resolution which
    does not work for the card? (I don't know the HP monitors, so I don't
    know whether there is a configuration menu which allows you to lock to a
    given resolution.
    My FEH (Field Engineer's Handbook) shows nothing about the
    jumpers, so you should leave them alone.
    What is wrong with *making* a null modem cable? You can find
    the pinout information in many places. If you have a small soldering
    iron, get the solder-tail type connectors. If you have the right
    crimper, use crimp terminal connectors. Since the voltage is no higher
    than about 12V at very low current, you can even leave the connectors
    without enclosure shells for short term use.

    Once you have that -- unplug the keyboard and the monitor, power
    up (without booting), and from the "ok" prompt, type:

    printenv output-device

    If it just shows "screen" you should be fine. If it shows

    screen:r1280x1024x75

    then this is forcing your resolution. Instead, try:

    setenv output-device screen

    so it will go to its default 1152x900 -- or to what it decides on when
    exchanging information with the monitor.

    Or -- you can try to make a temporary reset to default values by
    waiting until the power switch LED starts blinking, and press it twice
    -- about a second apart -- shortly after the blinking starts. This will
    reset the nvram settings to default -- only for the duration of this
    boot cycle. You can then try typing "set default" (I may not be
    remembering the words quite right -- can someone else confirm this?)
    You had a lot less powerful graphics card on the SB-100 --
    unless you added a card to it to replace the built-in framebuffer. And
    the monitor may be locked to a mode which is better for the SB-100.

    Good Luck,
    DoN.

    Don;

    Yep...you caught me on a typo -- it was 1280x1024x75.

    I bought them seperately, from two different vendors.

    LCD is blank until after the boot disk is read. NOTE: I wait
    until I hear the beep, use the L1-A sequence, then type in "boot
    cdrom"
    to get the machine to start the boot off of the boot disk.

    I will either scrounge up a cable from our IT department or consider
    making
    a null cable that I can use with my PC & Hyperterminal. (I'm also
    going to
    check around to see if I might even have one already).

    I'll try your suggestion about going to the default setting as well.
    I've looked at the HP menu settings and I can't seem to find a way to
    set the
    display options directly.

    Thanks for the suggestions. I'll see what happens tonight...

    Hi Don!

    Thanks for the tip about using the power switch to bring the system
    up in a "default" state. It worked!

    I saw the logo for the graphics card on the screen and also text
    about the system (here I thought I got a 1 Gb system, when now
    I find it has 8Gb of ram).

    I went into the nvram entries and found that entry 0 was corrupted.
    I checked my monitor to see what mode it locked onto (1280x1024x60),
    and programmed that value into location 0. I was then able to reboot
    the
    machine and see the banner & logo show up on my display.

    Looks like all I have to do now is to buy another fc-al disk drive (I
    only have a 33 Gb drive
    in this box).

    Thanks again!

    The maximum it will hold. Congratulations!
    Great. But "entry 0" rather puzzles me. From what you
    programmed, I presume that you mean the "output-device" entry.
    Note that they can be quite happy with the 156 GB 1" drives.
    I'm using several in various systems. That is enough so you can put
    everything on a single drive and mirror that onto a second drive every
    so often.
    You're welcome. Glad that it worked for you.

    Hmm ... a corrupt value may suggest that the coin cell clipped
    into the system board near the second CPU should be replaced. If you
    find it going incommunicado again after being powered off for a while,
    that is likely to be the cause.

    Good Luck,
    DoN.
