Thank you for your response. I have almost given up this after several
month of trial and errors.
I do not update grub but I have a symlink to grub.cfg with the kexec
--load vmlinuz etc. in the grub.cfg file.
As I understand it the boat.efi looks in the com.apple.Boot.plist to
find the "mach_kernel" and there it stops. I have tried different
"mach_kernels" with no success.
It seems to me that the mach_kernel is not loaded or can not find the
/boot/grub/grub.cfg or menu.lst (ln -s grub.cfg menu.lst).
How do I find out if the "mach_kernel" is loaded and is seraching for
the menu.lst?
Is the Ubuntu 8.04 the way to go with a "mach_kernel" proven to work?
Please help me out here.
Thanks
Sten

You can't use update-grub, since kexec won't use grub, kexec is the
new bootloader.
I think either update-grub is wiping out your menu.lst or turning it
into a symlink pointing to grub.cfg.
Try copying menu.lst to /boot/mb_boot_tv.conf which is looked for
before menu.lst according to source:
http://code.google.com/p/atv-bootloader/source/browse/trunk/initramfs/apps/boot_linux.sh
make sure you don't have a /mb_boot_tv.conf.
Then with each update to kernel, you'll need to manually update the /
boot/mb_boot_tv.conf file to point
to your new kernel.

I need help!
I can not get the installed Mythbuntu to boot from my Apple TV
internal disk.
I have tried many different installs at this point and spent days
(weeks) to try to get it work.
This is what I have and what I want to do.
1. I have an Apple TV with an internal 160GB PATA disk
2. I have the latest atv-boatloader with the right Parted GNU 1.8.8 on
a 9 GB usb stick
3. The atv-boatloader on the usb stick works perfect all the time and
is always the rescue point
4. I want to over-write the existing Apple TV internal PATA disk and
use it for Mythbuntu
5. I want to use Mythbuntu as a frontend with my Synology 107 NAS as
backend
6. I want to use VLAN as the player
This is what I have done so far
1. First I downloaded a LiveCD with Mythbuntu 10.10 to install on my
Apple TV
2. I made 3 partions on the disk since I was told the “EFI” and OSBoot
partition was not needed
3. I formatted the partitions as I was told in “Create and format
proper Apple TV” partitions”
4. I made a copy of the boot.efi from my usb stick to the recovery
partition on the atv disk
5. I downloaded the recovery files to my usb stick and made a copy to
the recovery partition on the atv disk as well
6. I did the checksum on the boot.efi
7. I booted the LiveCD with Mythbuntu 10.10 and dubble click the
install
8. After I successfully booted the Mythbuntu LiveCD and dubble-
clicked the Install, it hangs
9. I downloaded and burned several copies with the same result
10. Then I reformatted the entire disk with 5 partitions as in the
example “partitioning Linux”
11. The result was the same and my conclusion was that Mythbuntu 10.10
does not work with AppleTV – there is no information on Internet about
it
12. I downloaded and burned Mythbuntu 9.10 – back to basic and I
could do the Installation
13. After finishing the installation I tried to boot from the internal
disk without success
This is what I have done to try to boot from the internal Apple TV
disk
I have checked all files on the Apple TV disk and they looks ok
however the Grub.cfg refers to hd0,4 and that is /dev/sda5 not sda4.
The boot_linux.sh has the wrong initrd.gz
My Mythbuntu distribution is on hd0,3 and that is /dev/sda4. /dev/sda5
is the linux swap partition.
The update-grub does not work or I don’t know how to update the Grub.
I edited the menu.lst as follows:
default 0
title Mythbuntu
root (hd0,3)
kernel /boot/vmlinuz-2.6.31-14-generic root=/dev/sda4 ro quiet
processor.max_cstate=2
initrd /boot/initrd.img-2.6.31-14-generic
boot
I did update-grub and get an error. I looked in the file and saw a
command string but do not know how to execute.
I tried to boot the Apple TV manually using kexec like follows:
Mount /dev/sda4 /tmp
cd /tmp
kexec –load vmlinuz –initrd=initrd.img –command-line=”root=/dev/sda4
initrd=initrd.img”
kexec –e
First I saw a pink screen and then the TV went black. My atv is
connected to the TV with HDMI and I remembered that the LiveCD Install
did only have component for HD TV.
I changed the TV to component and there it was. So the kexec could
boot the Mythbuntu from my internal atv disk but not from the menu.lst
script above.
I updated the Mythbuntu to 10.04.1 LTS lucid, and it worked when I
used the vmlinus.old and initrd.img.old not with the new vmlinuz and
initrd.img. The kernel release is 2.6.24.3
Now I need help to automatic boat from the atv with the menu.lst
above.
I have tried everything I can think about but it seems to me as the
boot.efi never find the right loadpoint.
Thanks
Sten
