boot errors - getting past the ok prompt after install

[wdbreen]

Gday Guys,
I have just done an intsall of ubuntu-server on a sun netra 1125. The install went well until it rebooted for the first time. It tried to boot and gave the error:
"The file just loaded does not appear to be executable"

Then just an ok prompt.

My OBP version is 3.29

I need some help on getting past this point.

Cheers

Can you boot into rescue mode from CD and then chroot (the menu proposes to do so) into your already-installed linux root partition?

Sounds like either SILO's installation went wrong or the symlinks in / or /boot for the initrd-kernel are somehow
broken. I don't have a Sun box running permanently at home to copy& paste from. On my PC this looks somehow like this:

marc@blaze:/$ ls -al
[...]
lrwxrwxrwx 1 root root 32 2006-06-28 18:56 initrd.img -> boot/initrd.img-2.6.15-25-server
lrwxrwxrwx 1 root root 32 2006-06-22 20:26 initrd.img.old -> boot/initrd.img-2.6.15-23-server
[...]
lrwxrwxrwx 1 root root 29 2006-06-28 18:56 vmlinuz -> boot/vmlinuz-2.6.15-25-server
lrwxrwxrwx 1 root root 29 2006-06-22 20:26 vmlinuz.old -> boot/vmlinuz-2.6.15-23-server
[...]

Your kernel and initrd.img file names will probably be different.
In general, silo.conf refers to the symlink of initrd.img and will look for vmlinuz in the "root =" partition given in silo.conf.

Check that thes files or their symlinks exist in the places SILO will be looking for them.

Sounds to me as if you are using a CD image intended for another platform (like i386 or amd64). Use the SPARC image (http://releases.ubuntu.com/6.06/ubuntu-6.06-server-sparc.iso).

I had thought of that one, too. But how would he have been able to do an installation in the first place? He (or she?) claims the installation was successful...

I don't think that a CD-based installation would allow for messing the process up so badly that a kernel for a different architecture was installed. On the other hand.. no one ever knows...

To the OP:
Can you tell us what CD image you used?

Thanks for your replies guys!
Not long after i attempted a boot scsi0:0 (where the image is stored!) and it worked. Just need to look at some of the /boot files netztier referred to or the environment variables for booting.

Yes, it was a SPARC image i used. It was succesful, just not all the way. Having fun learning though.

Any idea when Ubuntu may release a desktop-sparc iso so that users can grab a gnome or kde gui??

That's another idea to check for - what file does OBP try to load when you have it boot disk at the ok > prompt

Hm. I see - I'll just have to do a proper installation fromn scratch with ubuntu-sparc server. My active setups are still based on the Dapper 6.06beta CDs. Aren't the ubuntu-desktop, kubuntu-desktop or xubuntu-desktop packages available for Sparc?

I even see kernel releases for my beta-based installations - so instead of installing a server-oriented kernel, a desktop-oriented kernel might also boost things a bit (I think it's the "preemptive" flag that does the trick - back in my gentoo days that thing really helped).
