Sunblade 2500 Firmware update seems to have failed. Can anyone help?

I recently updated the firmware on my Sunblade 2500 (Red) with patch # 119232-02. All seemed to go well, the machine shut down, and is now dead.

Upon power-on, it just sits there, the monitor doesn't synch up, and the fans are spinning 'fast', like they do when the machine is first powered up.

No keyboard lights, nothing.

How do I recover from this? Do I need to buy another prom for the machine? I understand that the part number is 525-2024, but I don't want to buy it and find out that I'm wrong.

Any help would be greatly appreciated.

Thank you in advance!!

    Hello Adam,

    did you read the patch installation instructions and Note 3: Modifications to Diagnostic Operation ?

    Did the flash programming really successfully finish ?
    Maybe it's just the extented diagnostics that require more time (the output is directed to the serial console port until the POST has finished and the framebuffer is initialized).

    The boot-rom isn't socketed ! If the flash operation failed and even flash recovery doesn't work, you have to replace the system board.
    Under rare circumstances flash recovery (FPROM high half booting) is the required.
    *Excerpt from the readme (with added comments):*

    Erasing the top half of the Flash PROM.
    Programming OBP into the top half of the Flash PROM.
    Verifying OBP in the top half of the Flash PROM.

    two copies of OBP, top half updated, bottom half=current

    Erasing the bottom half of the Flash PROM.
    Programming OBP into the bottom half of Flash PROM.
    Verifying OBP in the bottom half of the Flash PROM.

    new OBP in default location, bottom half

    Erasing the top half of the Flash PROM.
    Programming POST into the top half of Flash PROM.
    Verifying POST in the top half of the Flash PROM.

    finally program the updated POST

    Programming was successful.
    High half booting (by closing/installing Jumper JP5 on the system board) is required if the second step fails.

    Thank you sir.

    I've connected my null terminal cable, and it is indeed stuck in POST mode.

    I'm at the Sun Demon menu, looks something like

    0> 0 Return
    0> 1 Run all Tests in this Menu
    0> 2 Configure POST Environment
    0> 3 Peek/Poke interface
    0> 4 Scripting define
    0> 5 Enable/Disable CPU Caches
    0> 6 IO-Bridge Tests
    0> 7 CPU Tests
    0> 8 Memory Tests
    0> 9 Dump Device Registers
    0> ? Help



    How do I exit?

    When I try to exit, I get

    0>Selection:0
    0>At top level of menus, return to OBP?[y,n]:y
    0>Standalone POST, no OBP in prom, returning to POST menu.

    When I opened the case, JP5 was already closed.

    What do I do now?

    Thanks in advance!!

    Hello,

    When I opened the case, JP5 was already closed.

    My fault ! JP5 jumpered is the default (low half booting) for normal operation.

    0>Standalone POST, no OBP in prom, returning to POST menu.

    I think something went wrong during the update. If you remove the jumper and then power-on, does the system normally start ?

    Unfortunately I neither have access to a Blade 2500 nor to the Sun Knowledge Base.

    Michael:

    No luck. With it opened or closed, I still get the same DEMON menu, and it always complains that there is no OBP in PROM. So, it seems I can get into the PROM, but Open Boot is just not there.

    Is it time to replace the board? I'll buy one today if needed. Once I do that; move my CPUs and memory over, and assemble everything as it was, it should work?

    Thanks again!!

    Adam
