James,

    Ok, can I assume, since you mention you're running s10 fcs, that you
    have patch 118844-30 (5.10 x86 kernel patch) installed?
    ----
    I do not believe I have that patch installed.  But I see from the
    README that it has the multiboot file I need.
    ----
    Further, what *exactly* do you mean by this sentence
    "I am at a loss of how to generate the grub files"
    Which files are you referring to?
    ----
    There are several files in /boot which I don't know how to generate,
    but I assume bootadm does this.

Again, which files are you referring to?

/sbin/bootadm regenerates *one* file, which is
/platform/i86pc/boot_archive.

The other files that you might possibly be referring to are ones that are
supplied in Solaris 10 update 1 or with the patch that I mentioned.
....

    Did you ever have grub working on this system with Solaris?
    ----
    My box was built from the original s10 which had the old solaris
    boot mechanism, I don't think this was released externally.  I tried
    live upgrade, but to make a long story short, I rebooted it and the
    solaris boot started saying my root slice is invalid.  I fsck'd the
    disks and everything was clean, and all the data is there.  So, I
    believe once I get the grub working everything will come up.
    Do you have any idea how I can add that patch to the alternate root
    (I see it has the multiboot file), or should I just copy
    /platform/i86pc/multiboot from another x86 machine then install the
    patch after it is up?

So the answer to my question is, in fact, "no this host has not ever been
successfully booted with grub."


You mention that you get a message (from what?) saying that your root
slice is invalid. Please check your root device's path and compare it
to what is in /boot/solaris/bootenv.rc.

Once you've done that, you could rtfm on patchadd.

Finally, if you want grub on this system, please either grab a copy
of Solaris 10 update 1 and (upgrade) install that, or install the patch
mentioned above using the requisite and blessed procedures.

You're playing with how the system boots. Don't assume that you can
just get your Solaris 10 fcs system to use grub unless you follow the
procedures that Sun has documented and supplied.
