Jim, your instructions combined with Tim Wiley’s kernel build instructions worked great! I also used upgrade-manager to upgrade to 8.04 and it worked fan-tastic!! I’m now running 8.04 on my RAQ3 and I’m hoping to clone the drive into my RAQ3i as well. Thanks very much!!!

….um. Never mind. Turns out that running an nfs user server off a Ubuntu Dapper LiveCD does not and will not work.

BTW, note that the chroot step of the procedure assumes that the NFS server is running on x86 hardware. If you run it on SPARC/PPC/Itanium the chroot for apt-get will definitely not work. Just a friendly FYI.

Jim -

Hey, thanks for the guide on how to configure ubuntu on the Qube 3. Just a quick question - I configured a ubuntu NFS server using a LiveCD and then followed pretty much all of the instructions - except that right after I pick the network boot option I see the Qube3 come in for the DHCP lease (good) and then try for the NFS mount (also good), but for some reason it immediately ran into a kernel panic.

Any idea what I should look into for troubleshooting?

I've done all steps shown in the howto and installed the prebuilt kernel with: dpkg -i kernel * I symlinked vmlinux.bz2 with the vmllinuz file provied by the installer after a reboot the qube stops working with the following output (via serial console) EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Freeing unused kernel memory: 100k freed BOOTLOADER: Mapping in physical locations BOOTLOADER: load_addr=0xc2004000 ret_data=0xc2205cc4 BOOTLOADER: opening "/boot/vmlinux.bz2" BOOTLOADER: reading "/boot/vmlinux.bz2" BOOTLOADER: read 1312774bytes BOOTLOADER: unmounting / BOOTLOADER: calling reboot notifiers md: stopping all md devices. flushing ide devices: hda BOOTLOADER: mapping 22M-32M for ride home BOOTLOADER: disabling interrupts BOOTLOADER: flushing cache BOOTLOADER: Leap of faith!

I’m afraid I’ve fallen at the first hurdle. There’s no inittab in 7.10!

I€™ve just bought a Qube3 on eBay and, thanks to your HowTo, I probably saved several hours in installing Ubuntu.

I€™d like to add one thing, I had one issue, after completing strictly your install guide, the Qube was refusing to boot the new kernel and kept using the one in ROM. After several hours and retries, I realized that the issue wasn’t coming from the new kernel but from the cmos settings. I guess the former owner was issue the Qube with 2 disks in mirroring, the boot device and root device were set to ‘md1′ instead of ‘hda1′, this is why the Qube couldn’t even find my new kernel. I put back the correct value, rebooted and (yeepee!!) managed to get my Ubuntu 6.06 login prompt.

For those who might have the same issue, here are the commands to check and change those values.
Enter ROM mode by pressing when asked on the console, you should get this prompt:

Cobalt:Main Menu> boot

Cobalt:Boot Menu> read_boot_dev
md1

Cobalt:Boot Menu> set_boot_dev hda1
Boot device is set to 0×0301

Cobalt:Boot Menu> read_root_dev
md1

Cobalt:Boot Menu> set_root_dev hda1
Root device is set to 0×0301

Cobalt:Boot Menu> read_boot_type
From disk

Cobalt:Boot Menu> reboot
Rebooting - please wait……….

The Qube will now try to load your new kernel!!!

Thanks again for sharing your work,
Cheers,
Fabrice

Firt of all thanks a lot for your outstanding job! I don’t know Linux at all and I managed to have a RAQ 3 up and running just needing a couple of “educated guesses” following step by step the whole process indicated by you. I point them out just in case someone as dummy as myself in Linux could benefit of them:sudo apt-get install debootstrap nfs-user-serverdidn’t work for me prior to copy the sources.listand run apt-get updateI wanted to get the files from the cd and prior to issue the command sudo debootstrap dapper /nfsroot-x86 file:/media/cdrom0/ubuntu/ I had to mount the CD-ROM drive using mount /dev/hdc -t iso9660 /media/cdrom0I don’t know why but I didn’t managed to have more than the root and the swap partitionAt the beginning I wanted to use your “out of the box” kernel but “skipping” to the point you indicated I didn’t have a clue on how to proceed, so I went for compile a new onebeing such a “zero” on Linux I was shocked when a blue and gray window popped-up asking me to edit the kernel. I just exited having no clue and the installation luckily continuedduring this process I had a lots a wanrning (coming up from perl and/or python I cannot remember) asking to check the locales. Shall I check (how???) them and recompile the kernel?All the rest was perfect! Thanks a lot again for the great job and the opportunity you gave to lot of people like me to continue to us our beloved Cobalt boxes!
Ciao

IT WORKS!!! It’s only in search of a DHCP server… this explain the sliding cursor.
Many thanks for the support!

Without a null modem cable it’s impossible to say what’s happening. You’ll have to get one. I think you’re putting the cart before the horse to wonder if you’ve destroyed your Qube without spending a few dollars on a serial cable.
