help with open boot prompt

    i have a 1993 vinage sparc 10 system which was to be tossed so i grabbed
    it. i got a scsi(1) 7-cd changer plugged into the scsi(2) port on the
    box and i am ready to change the root passwd.

    however, upon booting the sys says scsi not responding
    i dont know much about the "ok" prompt but i see it is set to boot from
    disk, (but not net). how can i check that the cd is functional and to
    make the sys boot from cd?

    i have 11/99 solaris 7 software disk...that should be old enough for the
    sparc 10 right? what level of the os will run on the sparc 10?

    i've got Solaris 9 on an Ultra 10. X even works fairly well for a
    333mhz system. Solaris 7 even works on my old SS2 (sun4c), but i'm not
    using X.
    there's detailed instructions to be found on Sun's site on the open
    boot system and it's commands.

    The Sparc expects its boot CDROM to be on SCSI ID6. You can check
    whether this is the case from the OpenPROM, or, perhaps simpler, hold
    STOP + N as it boots to load defaults and then it will be set that way!

    I suspect though that you will have no joy with your CD changer as a
    boot device. Sparcs need a player that'll support an unusual block size.
    Many Toshiba SCSI devices seem to work for example, but many other
    brands don't.

    I'm sure others here will be able to fill in the (many) gaps and be a
    lot more precise, but I hope this stops you banging your head against a
    brick wall until they do!

    You may want to consider net-booting from another machine instead...

    the cd changer is a nakamichi mbr-7 with all of 2x speed :)
    after a bit of random keystrokes i got....

    "ok probe-scsi-all" returns (amongst other things)
    /[email protected],e0000000/[email protected],e0001000/[email protected],8100/esp00,8000

    "ok boot cdrom" returns
    Boot device:/iommu/sbus/[email protected],400000/[email protected],800000/[email protected],0:9 File and

    SCSI device 6,0 not responding
    Can't open boot device

    not sure what the probe-scsi-all is saying but it doesnt look like the
    cd is #6.
    how can i change it's id?

    Depends on the drive, most of them have a rotary or pushbutton selector
    on the back of the case to set the ID number. Make sure the end of the
    chain is terminated too.
    James Sweet, Mar 9, 2006

  7. That's it? The "other things" are probably the important bits. Does a
    CD device appear? What target?

    You should probably post the entire output. It shouldn't be more than a
    few lines in size.

    'cdrom' is just an alias for a particular target on a particular bus.
    You can give an alternate path to 'boot'.

    However, I really don't understand the :9 on the end of the string... I
    thought that should be a character from 'a' to 'h' representing the
    slice, and a sparc10 would want the sun4m slice of 'd'.

  8. HI,
    The Lastest Solaris release that will run on the SS10 is Solaris 9.

    Rich Teer Guest

    The OP (Peter) is talking about the sun4m-based SPARCstation 10, not
    the sun4u-based Ultra 10 to which you refer.

    Solaris 9 is the latest release of Solaris that supports the SS10.

    sorry. showing my ignorance here. didn't realize there was a
    difference between an ss10 and ultra-10. afaik they were one in the same :(

    why is that? 64 bit?

    cd changer is a nakamichi mbr-7 with all of 2x speed :)
    the target is 1
    th output list each of the 7, (0-6) cd's
    target 3 is the hd
    the :9 represents the fat fingers on my hands...it is indeed :d

    IIRC, drop of Supersparc (HyperSparc) CPU support.

  14. I wouldn't say that 64 bit was the *cause*, but it's certainly

    Dropping support for sun4m reduces the amount of code that has to be
    supported. Once you make the decision that sun4m isn't supported, then
    all the remaining SPARC platforms can handle 64 bit kernel mode and you
    can drop support for 32 bit kernel mode for more savings.

    They also dropped UltraSPARC 1 support, so Solaris 10 won't run on my
    now-10-year-old 167MHz Ultra 1E. Of course, the bug that allows the
    processor to be stalled when running 64 bit code might have something
    to do with it ;-).

    The big payoff is to eliminate all 32 kernels, which they didn't do.
    They kept 32 bit x86.

    Peter did you ever get a satisfactory answer to your problem.

    all scsi cdroms have 3 id jumpers each having a binary weighting, of 1,
    2, 4 combining what is on and what is off sets up any id between 0 and 7.
    you will therefore want two set together, to set it to 6

    probe-scsi will tell you when you have got it rights.

    to boot from scsi cdrom to sparc you will also need to set the blocksize
    jumper from to either 512 or 2048, cant remember which one is PCx86 and
    which is sparc, but only one will work for sparc.

    then on sparc 10 you should by default have the 1st disk set to ID 3,
    and the second to id 1, this is just convention, and will ensure that
    its setup as sun intended, it does not mean that it has to be that way,
    its just how it was origionaly deployed.

    make sure your bios (nvram in suns language) is setup to defaults with
    the command set-defaults.

    now "boot cdrom", or b cdrom depending upon the prompt, ie OK or ?>

    regards peter

    then finaly when all its setup

    Well, if you take into account how relatively new 64-bit is to the x86
    world (*snicker*), you can hardly blame them for doing that.

    64-bit isn't *that* new to x86 and, as far as I can tell, there wasn't a
    significant installed base of Solaris on x86. So that leaves new
    installs on old or improperly spec'ed hardware.
